Abstract:
Nanotechnology and nanomedicine is a cutting-edge field that is growing, providing new solutions in different areas. These new technologies in the medical area cover many possibilities for the study, treatment and diagnosis of different diseases in a more efficient and personalized way. A key tool recently developed in biomedical engineering research thanks to this technology are implantable sensors. The development of miniaturized implantable biosensors in the human body has revolutionized the field of medicine in terms of diagnosis, and monitoring of numerous conditions and diseases, such as cardiovascular disorders and metabolic problems. One of the great advances that these sensors have introduced is their ability to monitor clinical data practically in real time, obtaining records of the body's biophysical and biochemical parameters in a continuous way and for extended periods. This talk will present new technologies in implantable sensors specificaally in blood vessels, which allow for continuous monitoring and early detection of diseases. We will show the developments achieved in this area by our research group for different applications, such as monitoring ischemia in fetuses for detection of fetal growth restriction and the detection of biomarkers of heart disease for early diagnosis. Future trends and the advantages and limitations of this technology will be discussed.

Abstract:
Nanomedicine is the use of nanomaterials to improve disease prevention, detection, and treatment which has resulted in hundreds of FDA approved medical products. While nanomedicine has been around for several decades, new technological advances are pushing its boundaries. For example, this presentation will present an over 25 year journey of commercializing nano orthopedic implants now in over 30,000 patients to date showing no signs of failure. Current orthopedic implants face a failure rate of 5 – 10% and sometimes as high as 60% for bone cancer patients. Further, Artificial Intelligence (AI) has revolutionized numerous industries to date. However, its use in nanomedicine has remained few and far between. One area that AI has significantly improved nanomedicine is through implantable sensors and neurological applications. This talk will present research in which implantable sensors, using AI, can learn from patient’s response to implants and predict future outcomes. Such implantable sensors not only incorporate AI, but also communicate to a handheld device, and can reverse AI predicted adverse events. Examples will be given in which AI implantable sensors have been used in neurology to inhibit implant infection and promote prolonged neural function. Moreover, in vitro and in vivo experiments will be provided that demonstrate how nanotechnology can be incorporated into neurology to help human health.

Abstract:
Spin-devices are operated by flipping spins without moving charges in space, which can lead to ultra-low-energy switching and can replace the traditional energy-consuming transistors in our future information processing systems. Particularly, the electric field-induced magnetization switching has emerged as an energy-efficient paradigm. Here we review the recent developments on ultra-low-energy, fast, and area-efficient spin-devices using strain-mediated magnetoelectric multiferroic composites. The feasibilities are shown for both the digital logic design and the analog computing with transistor-like high-gain region in the input-output characteristics. We further show that the exchange-coupled nanomagnets can increase thermal stability tremendously at low dimensions and thus would pave the pathway towards ultra-high-density non-volatile information storage and logic systems. We also review the equivalent spin-circuit representation of spin-devices by considering spin potential and spin current, which is crucial for explaining and proposing experiments. We construct the spin-circuit representation of spin pumping, which occurs when there is a material adjacent to a precessing magnetization and therefore it is particularly necessary to be incorporated in the device characteristics measurements. We further develop a general strategy to determine the interfacial complex spin mixing conductance from the experimental results of ferromagnetic resonance and spin pumping for magnetic insulators, which are very promising for energy-efficient spintronic devices. We also construct the spin-circuit representation of spin-torque ferromagnetic resonance particularly using magnetic insulators and heavy metals and spin pumping into topological insulators, considering both the bulk and surface states with parallel channels, which allows for the explanation of high spin Hall angle close to the maximum magnitude of one from the experimental results. We further review the recent progress on experimental results e.g., fabrication of ultrathin samples and thickness measurements, ferromagnetic resonance for the characterization of magnetization damping parameter and ultrasensitive measurements of strains for the development of energy-efficient spin-electronics.

Abstract:
Concussive head injury (CHI) is one of the major risk factors in developing Alzheimer’s disease (AD) in military personnel at later stages of life. Breakdown of the blood-brain barrier (BBB) in CHI leads to extravasation of plasma amyloid beta protein (AbP) into the brain fluid compartments precipitating AD brain pathology. Oxidative stress in CHI or AD is likely to enhance production of nitric oxide indicating a role of its synthesizing enzyme neuronal nitric oxide synthase (NOS) in brain pathology. Thus, exploration of the novel roles of nanomedicine in AD or CHI reducing NOS upregulation for neuroprotection are emerging. Recent research shows that stem cells and neurotrophic factors play key roles in CHI induced aggravation of AD brain pathologies. Previous studies in our laboratory demonstrated that CHI exacerbates AD brain pathology in model experiments. Accordingly, it is quite likely that nanodelivery of NOS antibodies together with cerebrolysin and mesenchymal stem cells (MSCs) will induce superior neuroprotection in AD associated with CHI. In this presentation, co-administration of TiO2 nanowired cerebrolysin- a balanced composition of several neurotrophic factors and active peptide fragments, together with MSCs and monoclonal antibodies (mAb) to neuronal NOS is presented for superior neuroprotection following exacerbation of brain pathology in AD by CHI based on our own investigations. Our observations show that nanowired delivery of cerebrolysin, MSCs and neuronal NOS in combination induce superior neuroprotection in brain pathology in AD exacerbated by CHI, not reported earlier.

Abstract:
Sleep deprivation induces amyloid beta peptide and phosphorylated tau deposits in the brain and cerebrospinal fluid together with altered serotonin metabolism. Thus, it is likely that sleep deprivation is one of the pre-disposing factors in precipitating Alzheimer’s disease (AD) brain pathology. Our previous studies indicate significant brain pathology following sleep deprivation or AD. Keeping these views in consideration in this presentation ananodelivery of monoclonal antibodies to amyloid beta peptide (AbP), phosphorylated tau (p-tau) and tumor necrosis factor alpha (TNF-a) in sleep deprivation induced AD is discussed based on our own investigations. Our results suggest that nanowired delivery of monoclonal antibodies to AbP with p-tau and TNF-a induces superior neuroprotection in AD caused by sleep deprivation, not reported earlier.

Abstract:
This talk will focus on the description of surface functionalized ultrafine CoFe2O4 Nanoparticles (NPs), with mean diameter ~ 5 nm. The investigated properties include DC magnetization and AC susceptibility measurements over the temperature range of 4 – 400 K. All evaluated NPs present the same CoFe2O4 core, with different molecular surface coatings, increasing gradually the number of carbon atoms in the coating layer, in the following list: Glycine (C2H5NO2), Alanine (C3H7NO2), Amino butanoic acid (C4H9NO2), Amino hexanoic acid (C6H13NO2), and Amino dodecanoic acid (C12H25NO2). Importantly, samples were intentionally fabricated in order to modulate the core-core magnetic dipolar interaction, as the thickness of the coating layer increases with the number of carbon atoms in the coating molecule. The magnetic data of the uncoated CoFe2O4 NPs it is also presented for comparison. All investigated CoFe2O4 NPs (coated and uncoated) are in magnetically blocked state at room temperature as evidenced by ZFC/FC measurements and the presence of hysteresis with ~700 Oe coercivity. Low temperature magnetization scans show slightly constricted hysteresis loops with coercivity decreasing systematically while the number of carbon atoms in the coating molecule decreases, possibly resulting from differences in magnetic dipole coupling between NPs. Large thermomagnetic irreversibility, slow monotonic increase in the FC magnetization and non-saturation of the magnetization give evidence for the Cluster Glass (CG) nature in the CoFe2O4 NPs. The out of phase part of AC susceptibility for all samples shows a clear frequency dependent hump which is analyzed to distinguish Super Para Magnetic (SPM), Cluster Glass (CG) and Spin Glass (SG) behavior by using Néel-Arrhenius, Vogel- Fulcher, and power law fitting.

Abstract: 
Water quality monitoring plays a major role in safety and public health management. Bacteria detection in water solutions can prevent contamination and diseases. This paper presents a Kretschmann surface plasmon resonance sensor for bacteria detection in water solutions. The sensor had a 633 nm He-Ne laser source and a BK7 prism with angle interrogation to assess its feasibility. The sensor was coated with Ag/ZnO/Graphene. The coated sensor showed a 70% sensitivity improvement over the Silver-coated sensor. This improvement in sensitivity is crucial for early detection of bacteria in water solutions, ultimately leading to more effective contamination prevention measures. The results demonstrate the potential of the Kretschmann surface plasmon resonance sensor for enhancing water quality monitoring and public health safety.

Abstract:
Silicon Carbide (SiC) has emerged as a leading material in power electronics due to its superior physical and electrical properties compared to conventional Silicon (Si). With a wide bandgap (~3.26 eV for 4H-SiC), high thermal conductivity, and a high critical electric field strength, SiC enables devices that operate at higher temperatures (>200?°C), switch at faster speeds, and withstand higher voltages. These characteristics lead to reduced conduction and switching losses, improved energy efficiency, and smaller, lighter system designs. As a result, SiC devices are increasingly adopted in demanding applications such as electric vehicles (EVs), renewable energy systems, aerospace, and industrial power conversion. The synthesis of high-quality SiC involves both traditional and advanced techniques. While the Acheson process remains foundational for producing bulk material, methods like Physical Vapor Transport (PVT), Chemical Vapor Deposition (CVD), and sublimation are employed to grow high-purity single-crystal SiC. PVT is the standard technique for producing large-diameter 4H-SiC boules, whereas CVD is the method of choice for epitaxial layer growth due to its precise control over doping and thickness—essential for device performance. Fabricating SiC-based Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) requires a sequence of high-precision steps. These include epitaxial layer deposition, ion implantation to form source and drain regions, high-temperature annealing for dopant activation, thermal oxidation for gate oxide formation, and gate electrode deposition. A significant challenge lies in the high interface trap density at the SiC/SiO? interface, which can degrade channel mobility. To mitigate this, post-oxidation annealing in nitric oxide (NO) or alternative nitridation treatments is applied. Advanced lithography, etching, and metallization processes complete the device fabrication. In conclusion, SiC is redefining the landscape of power electronics. While challenges in crystal growth, defect control, and interface engineering remain, ongoing research continues to unlock the full potential of SiC, paving the way for the next generation of efficient, reliable, and compact power devices.

Currently a Master’s student in Rehabilitation Sciences at Universidade Nove de Julho (São Paulo, Brazil), Kimberlly conducts in vitro research using C2C12 cells exposed to hyperglycemic conditions and treated with photobiomodulation. Her work explores cellular mechanisms and the therapeutic potential of light in metabolic disorders related to diabetes. Passionate about innovation and driven by scientific challenges, she aims to contribute to advancing health and rehabilitation through evidence-based discoveries.

Abstract:
Introduction: Chronic hyperglycemia is associated with metabolic changes that contribute to complications of diabetes mellitus, including insulin resistance and reduced glucose uptake. In vitro models using the C2C12 myoblasts lineage are widely used to investigate cellular mechanisms triggered by excess glucose, especially in muscle differentiation processes. Photobiomodulation (PBM), applied by means of low-level laser irradiation, has been shown to be able to modulate mitochondrial bioenergetics, reduce pro-inflammatory markers, and favor cell viability and differentiation. However, there is still a paucity of studies investigating the effects of PBM in conditions of metabolic stress, such as hyperglycemia. The present study aims to evaluate whether PBM can attenuate changes induced by the hyperglycemic condition in C2C12 cells cultured in vitro. C2C12 cells will be exposed to glucose concentrations of 5.5 mM (control), 25 mM, 45 mM, and 60 mM, with or without PBM treatment. Irradiation will be performed using an AlGaAs diode laser (780 nm, 70 mW, 26.25 J/cm², 15 s exposure time), followed by incubation for 24 h, 48 h, and 72 h in 96-well plates (10? cells/well). Cell viability will be assessed using the MTT assay, ATP synthesis will be measured with a luminescence-based kit, and cellular morphology will also be evaluated. Previous studies have demonstrated beneficial effects of PBM on mitochondrial function and gene expression in C2C12 cells, supporting the chosen model and experimental parameters. It is hypothesized that PBM will attenuate the deleterious effects of hyperglycemia, preserving functional characteristics and promoting cellular metabolism in C2C12. Statistical analysis: Data will be analyzed using ANOVA followed by Tukey’s post hoc test.

Mohammad Hossein Shaker, born in Tehran in 1998, moved to Brazil in 2019 and earned his Dentistry degree from Universidade Nove de Julho (UNINOVE) in 2023. He is currently pursuing a Master’s in Biophotonics Medicine at UNINOVE under Prof. Dr. Cinthya Cosme Gutierrez Duran, focusing on lasers and photobiomodulation in health sciences. His research includes laser therapy for post-operative pain, dental crowding treatments (CPAQV Journal, 2024), and the effects of photobiomodulation on oxidative stress in macrophages.

He has also designed clinical protocols for rhinoplasty recovery and platelet viability. Professionally, he has experience in São Paulo dental clinics with post-surgical laser therapy and PRP applications, and training in anatomical dissection at USP. His current focus is macrophage modulation and innovative therapeutic strategies for inflammation and oxidative stress control.

Abstract:
Oxidative stress is a key factor in the pathogenesis of chronic inflammatory diseases, leading to cellular dysfunction and increased production of pro-inflammatory mediators. Macrophages play a central role in the immune response, and their activation under oxidative stress contributes significantly to the inflammatory process. The J774A.1 murine macrophage lineage is a well-established in vitro model for studying inflammatory responses and oxidative stress. Photobiomodulation (PBM), using low-level laser therapy, has demonstrated anti-inflammatory and antioxidant effects in various cellular models by modulating mitochondrial function and reducing Reactive Oxygen Species (ROS) production. However, its effects specifically on macrophages under controlled oxidative stress conditions remain underexplored. This study aims to investigate whether PBM can attenuate the inflammatory and oxidative damage induced by Hydrogen Peroxide (H?O?) in J774A.1 macrophages. Cells will be exposed to different concentrations of H?O? (50 ?M, 100 ?M, and 200 ?M) to induce oxidative stress and will be treated or not with PBM using a red laser (660 nm, 50 mW, 3 J/cm², 60 s/well). Cell viability (MTT assay), morphological changes, and the production of inflammatory markers (TNF-?, IL-6, iNOS) and Nitric Oxide (NO) will be analyzed. Previous studies support the use of PBM parameters for biostimulation and its potential to modulate immune responses. We expect that PBM will reduce cell death and suppress the release of pro-inflammatory cytokines and NO in H?O?-stressed macrophages, demonstrating its protective and anti-inflammatory potential. This ongoing study may contribute to understanding the mechanisms of PBM as a non-pharmacological strategy for managing oxidative stress-related inflammatory conditions.

Abstract:
Neck pain, defined as painful conditions associated with the cervical spine, is a common syndrome that often causes pain and restricted movement. Among the available therapeutic approaches, manual therapies are widely used and have shown positive outcomes in many cases. The pompage technique, a form of manual therapy, aims to reduce pain and improve cervical range of motion (ROM), motor control, and overall function. Photobiomodulation (PBM) using LEDs represents another non-invasive and easily applied modality with potential therapeutic benefits. This randomized, controlled, double-blind clinical trial investigated the effects of pompage, with or without LED-based PBM therapy, on cervical ROM in patients with chronic nonspecific neck pain. Participants of both sexes, aged 18–62 years, were screened, and eight individuals completed the study protocol. They were randomized into two groups: (1) Pompage group (n=5), receiving only manual therapy with pompage; and (2) Pompage + LED group (n=3), receiving pompage followed by PBM therapy with an LED plate (264 diodes: 132 red at 660 nm and 132 infrared at 850 nm; 8 mW each; 9.6 J/cm²; 16 mW/cm²; 10 minutes per session). All participants attended 10 sessions, twice weekly. Cervical ROM was assessed with a goniometer before and after the intervention. Results: The pompage group showed a significant improvement in cervical extension and left lateral rotation ROM at the end of the treatment compared to baseline (P=0.02). The Pompage + LED group did not show statistically significant differences, although mean improvements were observed. Conclusion: Pompage alone promoted significant gains in cervical ROM in patients with chronic nonspecific neck pain, whereas the addition of LED PBM did not yield further statistically significant benefits.

TriLite’s technology is based on compact optical solutions, proprietary, multi-parameter algorithms, which deploy advanced machine learning algorithms to offer the LBS modules of unprecedented size, weight and image quality. Our award-winning, compact and lightweight Trixel® 3 LBS display engine combines a single two-dimensional MEMS mirror, unified RGB laser module approach, micro-optics, and a unique Trajectory Control Module that shifts the calibration complexity from hardware to software. Our projection display works in all environments, ranging from the direct sunlight to the dark rooms.  It offers low power consumption, adequate contrast and brightness, full color  (? 214 % over sRGB), and low latency to ensure that the projected augmented reality images naturally integrate with the real-object surroundings and are prone to spatial motion (a key characteristic to avoid the motion sickness). Trixel 3 has been designed from the ground-up concept to mass-manufacturing and is fully compatible with the state-of-the-art waveguides without requiring the projection or relay optics, making an entire compact and appealing wearable system. The presentation will also focus on advantages of the LBS technology in comparison with other existing displays such as for example, micro-LED (µLED), LCOS and OLED displays. 
Biography:
Dr. Bo Qu is currently an associate professor and doctoral supervisor at Peking University. He specializes in the field of organic optoelectronics (e.g., perovskite solar cells). To date, he has published over 100 SCI-indexed papers in international academic journals. Among them, more than 40 papers have been published in internationally authoritative journals such as Science, Chemical Society Reviews, Adv. Science, Small and Adv. Func. Mater., etc.

Abstract:
Perovskite solar cells (PSCs) have attracted broad attention. The certified efficiency has exceeded 26%, which is comparable to silicon-based counterparts. However, the environmental problems caused by the lead in perovskite restrict their large-scale applications. If a monovalent metal ion and a trivalent metal ion are used instead of two lead ions, a double perovskite A2M+M3+X6 is realized. In order to resolve toxicity of lead-based perovskites, Bo Qu group prepared PSCs based on lead-free double perovskite Cs2AgBiBr6 in 2017 (Adv. Sci. 2018, 5, 1700759), and then fabricated semi-transparent solar cells with an average visible light transmittance of  73% ( Sol. RRL 2020, 4, 2000056). However, the relatively large bandgap (~2.0 eV) of  Cs2AgBiBr6 hinders its optoelectronic applications in longer wavelength bands of visible and near-infrared regions. We replaced some of Bi elements in Cs2AgBiBr6 with trace doping (~1%) of iron (Adv. Function. Mater. 2021, 322109891) and ruthenium (Mater. Adv. 2022, 3, 4932) to broaden its absorption range to near-infrared region (1200-1350 nm). The above single crystal materials exhibit excellent near-infrared light detection. And we were invited to write a review article (J. Phys. Chem. Lett. 2023, 14, 5310). At present, the photovoltaic performance of lead-free perovskite still does not meet theoretical expectations. We have summarized the problems that exist in different lead-free perovskites (Mater. Today Energy 2018, 8, 157; Adv. Energy Mater. 2019, 1902496) and these limitations were mainly ascribed to low carrier transport and self trapping effects caused by low structural or electronic dimension of lead-free perovskites, as well as the non-radiative recombination. The bottleneck in the application of lead-free perovskite photovoltaics can be overcome by regulating the structural or electronic dimensions, and we were invited to publish a cover article in Chemical Society Reviews (2024, 531769-1788) entitled "Breaking the Bottleneck of Lead Free Perovskite Solar Cells through Dimensional Modulation". On the other hand, ?black-phase formamidinium lead iodide (a-FAPbI3) perovskites are the desired phase for photovoltaic applications, but water can trigger formation of photoinactive impurity phases. The conventional coordinative solvent dimethyl sulfoxide (DMSO) promoted photoinactive impurity phases formation under high relative humidity (RH) conditions because of its hygroscopic nature. Recently, we introduced chlorine-containing organic molecules to form a capping layer that blocked moisture penetration while preserving DMSO-based complexes to regulate crystal growth. We report PCE of >24.5% for perovskite solar cells fabricated across an RH range of 20 to 60%, and 23.4% at 80% RH. The unencapsulated device retained 96% of its initial performance in air (with 40 to 60% RH) after 500-hour maximum power point operation.(Science, 2024, 385, 161-167).

Camilo Cadena is a Philosopher and an undergraduate Physics student at the Industrial University of Santander. He is a part of the Optics and Signal Processing Research Group, where I focus on polarization and birefringence, working with geometric algebras and quaternions, as well as Python-based computational tools. He is particularly interested in advancing technology in these research areas

Abstract:
In the characterization of a birefringent medium, two fundamental groups of parameters can be distinguished. On one hand, the intrinsic parameters describe the medium’s inherent birefringence —encompassing the elliptical retardation, the azimuth, and the ellipticity of the principal modes. On the other hand, the equivalent parameters, derived from Jones’ Theorem I, decompose the elliptical birefringence into a combination of equivalent linear birefringence (with its corresponding retardation and azimuth) and equivalent circular birefringence (optical activity). To date, most experimental methods tend to measure one or the other group of parameters separately, which can lead to ambiguous results due to the non-injective relationships between them. In this work, we present a methodology that simultaneously and independently determines both sets of parameters without ambiguity, by means of a polarimetric and geometric analysis on the Poincaré sphere. Furthermore, we introduce a clear physical interpretation of the equivalent parameters based on the Law of Elliptical Birefringents, which enables the determination of all possible emerging polarization states of the birefringent medium without requiring its rotation.The effectiveness of this proposal was validated in devices with different birefringence configurations, showing agreement among measurements, theoretical results, and other experiments. Thus, we demonstrate that jointly determining the intrinsic and equivalent parameters provides a comprehensive description of birefringence, avoiding common ambiguities and enhancing potential applications in metrology, polarization control, and optical device design.

Abstract:
Surface Plasmon Resonance (SPR)-based biosensors are renowned for their high sensitivity, real-time monitoring, and label-free detection, making them vital tools in medicine, industry, and agriculture. SPR occurs at the metal–dielectric interface when free electron oscillations create confined surface excitations. The most common configuration, the Kretschmann setup, involves a prism, a thin metal film, and a sensitive medium. This study presents a Surface Plasmon Resonance (SPR) sensor design that includes an SF10 prism, a 70 nm silver layer, and a periodic structure of graphene and a 7 nm MoS? layer, all optimized for malaria diagnostics. In this arrangement, a thin metal film is deposited on a prism to exploit SPR phenomena for sensing. Additionally, layers with unique optical properties, such as graphene and two-dimensional transition metal dichalcogenides (MX?), are often incorporated to enhance the sensor's performance and operate in the near-infrared (NIR) range. NIR wavelengths yield sharper resonance curves and permit imaging of thicker films with higher contrast. Using an incoherent light source in NIR helps eliminate laser fringe issues. Reflectivity is a parameter calculated using the ABCD matrix method in the Kretschmann framework to detect changes in the refractive index of the sample. The sensor detects refractive index changes in Red Blood Cells (RBCs) to distinguish healthy cells from malaria-infected ones in three stages: ring, trophozoite, and schizont. The refractive index of healthy RBCs was 1.399±0.006 RIU, while infected RBCs showed values of 1.395±0.005 RIU (ring), 1.383±0.005 RIU (trophozoite), and 1.373±0.006 RIU (schizont). Sensitivity measurements reached 198.08 and 201.52 deg/RIU for refractive index changes of 0.005 and 0.007, respectively. Optimized reflectivity values were 0.9530±0.006 a.u. (healthy), and 0.9439, 0.8946, and 0.8193 a.u. for the three infection stages. These results enable reliable differentiation between healthy and infected RBCs, demonstrating SPR's potential in malaria diagnosis through precise reflectivity analysis.

Abstract:
Despite their significant potential to enhance device performance, superconductors are still underutilized in Terahertz (THz) photonics. Our research aims to address this gap by employing nano-superconductor layers to create photonic bandgaps (PBGs), which are essential for improving the efficiency and precision of optical and photonic devices. The unique properties of THz PBGs facilitate advancements in high tech components such as sensors, filters, and communication systems. As a result, there is increasing interest in tuning and manipulating these PBGs for specific applications. This study explores the interaction of transverse electric (TE) and transverse magnetic (TM) modes of THz waves with photonic layered media using the Transfer Matrix Method under various controlled conditions. We designed a one-dimensional photonic crystal (1DPC) comprising two types of high temperature superconductors, HgBa2CaCu2O(6+x) (Hg-1212) and Bi2Sr2Ca2Cu3O(10+x) (Bi-2223), along with two suitable dielectrics. The periodic arrangement of these layers results in a transmittance spectrum featuring several omnidirectional PBGs and tunable peaks sensitive to factors such as periodicity, lattice constants, and the angle of incidence. To optimize the spectrum for selective filtering of specific wavelengths, we utilized Mixed-Quasi-Periodic (MQP) sequences that combine the 1st-order Cantor and 2nd-order Thue-Morse sequences. This approach resulted in the formation of Dirac-delta-function-like peaks within the frequency range of 9.9 to 10.8 THz. By carefully tailoring the photonic band gaps (PBGs) and transmittance properties, the proposed structure is well-suited for advanced THz applications, including precision spectral filtering in communication systems, high-resolution imaging for medical diagnostics, and enhanced material characterization in industrial sensing. Our findings demonstrate that MQP sequences can create new opportunities in THz photonics by allowing for precise control of PBGs within superconducting photonic media.

Abstract: 
This work reports a novel eco-friendly synthesis of copper oxide nanoparticles (CuO NPs) using plant extract. These nanoparticles demonstrated strong potential for applications in both environmental remediation and antimicrobial activity. X-ray diffraction analysis confirmed the monoclinic crystal structure of the CuO NPs, with a calculated crystallite size of 11 nm. Morphological characterization using scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) revealed a diverse range of shapes, including elongated, hexagonal, and pentagonal forms, features that enhance surface reactivity. Energy-dispersive X-ray spectroscopy (EDX) confirmed the elemental presence of copper and oxygen in the synthesized material. UV-visible spectroscopy showed a distinct absorption peak at 363 nm, indicating the successful formation of a visible-light-responsive CuO photocatalyst. The optical band gap was estimated to be 2.36 eV based on the absorption spectrum. For adsorption studies, key operational parameters such as pH, initial dye concentration, catalyst dosage, and contact time, were systematically optimized. Under visible light irradiation, the CuO NPs achieved 98.9% degradation of Methyl Orange dye within 90 minutes. Kinetic analysis followed a pseudo-first-order model, with a rate constant of 0.073?min?¹. Furthermore, the synthesized nanoparticles exhibited notable antibacterial activity, forming clear inhibition zones against both Gram-positive and Gram-negative bacteria. Overall, this green synthesis route offers a sustainable and low-toxicity strategy for producing multifunctional CuO NPs, highlighting their potential in wastewater treatment and antimicrobial defense.
