Abstract The major challenge in developing efficient photovoltaic devices is achieving highlight absorption, optimal charge transport, and low recombination losses. In this work, the effect of the immersion bath numbers in the chemical bath deposition (CBD) technique on the properties of bismuth oxysulfide (Bi₂O₂S) thin films, as emergent materials, was studied. The films were synthesized under eco-friendly conditions, using a low-concentration bismuth nitrate precursor and thioacetamide as the sulfur source, and under basic conditions at moderate temperature, with a reaction time of 3 h. X-ray diffraction demonstrated the formation of a crystalline Bi₂O₂S phase, and the morphological… More >

Abstract This study presents a comparative investigation of the structural, DC electrical, and magnetic properties of pure cadmium sulfide (CdS) and 10% chromium-doped CdS (Cd_0.9Cr_0.1S) nanocrystalline thin films deposited by thermal evaporation. X-ray diffraction analysis confirmed the polycrystalline hexagonal (wurtzite) structure of both films with no detectable secondary phases. Upon Cr doping, the full width at half maximum (FWHM) of the principal diffraction peaks increased systematically, leading to a reduction in average crystallite size from 19.8 nm to 13.9 nm, accompanied by an increase in lattice strain (from 2.48 to 3.52) × 10⁻³ and dislocation density (from… More >

Abstract The human exposure to hazardous ionizing radiation is increased due to the progression of nuclear technology across energy, medicine, and industrial sectors, etc. Developing transparent shielding materials is essential to overcome the structural and opacity limitations of traditional materials like concrete. The 30TeO₂-xPbO₂-xBi₂O₃-(70 − 2x)B₂O₃ (x = 10, 12, 14 and 16 mol%) glasses are prepared via the melt-quenching technique. The density (ρ) increases from 4.759 to 5.561 g cm⁻³ due to the incorporation of heavy metal oxides (HMOs). The molar volume (V_m) increases from 32.194 to 33.657 cm³ mol⁻¹. The oxygen packing density (OPD) decreased from 80.761… More >

Abstract Using first principles calculations, we have systematically studied the structural, elastic, mechanical, lattice dynamic, and thermodynamic properties of the CuBS₂ semiconductor. The calculated structural parameters are in good agreement with the experimental values. The obtained elastic constants confirm that the compound is mechanically stable. The B/G ratio of CuBS₂ indicating that this crystal possesses ductile characteristics. Using the ELATE software, 3D and 2D visualizations of anisotropic elastic properties, namely, the maximum and minimum values of Young’s modulus (E), shear modulus (G), linear compressibility (β), and Poisson’s ratio (ν), have been analyzed. Furthermore, we calculated the elastic anisotropy index (A^U, A_B,… More >

Abstract Thin films of Cu_xZn_1−xS nanocomposite with varying copper content (x = 0.3, 0.5, and 0.7) were successfully synthesized by the pulsed laser deposition (PLD) technique from their fabricated powders by the precipitation method for optoelectronic applications. The impact of Cu content on the film’s structural, morphological, optical, and electrical characteristics was investigated. Elemental composition analyses indicated that thin CZS films consisted only of their constituent elements and were free of any noted impurities. XRD patterns demonstrated that all as-grown thin films were polycrystalline in nature and adopted various planes and phases of CuS and ZnS binary… More >

Abstract Cadmium (Cd) doping has enhanced the mineral properties, glass mesh, and movement traits of the Se₉₀Te₁₀ glassy alloy. The (Se₉₀Te₁₀)₉₅Cd₅ alloy has a strength 0.032 kN, accompanied by limited ductility, and displays brittle fracture behavior typical of amorphous chalcogenide glasses. (DSC) at varying heating rates was employed to examine the crystallization kinetics in bulk Se₉₀Te₁₀ and (Se₉₀Te₁₀)₉₅Cd₅ compositions; X-ray diffraction analysis was utilized to identify the crystalline structure of Se₉₀Te₁₀ and (Se₉₀Te₁₀)₉₅Cd₅, confirming the non-crystalline nature of both materials. Various kinetic frameworks were developed utilizing activation energies for glass transition and crystallization processes. “The Kissinger equation” was employed More >

Abstract The rapid proliferation of Internet of Things (IoT) devices across smart homes, healthcare facilities, industrial networks, and smart cities has raised critical security concerns, particularly regarding device authentication. IoT devices are typically characterized by limited computational resources, constrained memory, and restricted energy budgets, which renders the deployment of traditional cryptographic protocols infeasible; consequently, lightweight authentication schemes are required. Although numerous lightweight authentication protocols have been proposed, a systematic risk evaluation of such protocols against established threat modeling frameworks remains largely absent from the existing literature. This paper presents a systematic literature review (SLR) based on… More >

Abstract Food packaging films play a crucial role in maintaining food quality and safeguarding human health, making the development of advanced packaging materials an important research priority. Conventional petroleum-based plastic films suffer from poor degradability and may pose environmental and potential health concerns, while many currently available preservative films still exhibit limited freshness-retention performance. Therefore, the development of environmentally friendly, non-toxic, biodegradable, and efficient food-packaging materials is of great significance. In this study, coaxial electrospinning was employed to fabricate a core–shell nanofiber film by encapsulating resveratrol within gelatin/zein (GA/ZN) fibers, aiming to enhance the preservation performance… More >

Abstract Inflammatory liver injury represents a significant clinical challenge, characterized by a hostile immune microenvironment and extensive tissue damage. Although silymarin and mesenchymal stromal cells (MSCs) show promise in treating inflammatory liver injury, their efficacy is restricted by the drug’s poor bioavailability while MSC therapy is hampered by low cellular viability under inflammatory stress. To overcome these challenges, we engineered a droplet-microfluidic-assisted platform to co-encapsulate silymarin and MSCs within uniform, biocompatible polyethylene glycol-norbornene (PEGNB) hydrogel microspheres. This design establishes a dual-functional scaffold that supports MSC survival by shielding them from the harsh milieu while enabling the… More >

Abstract Reducing the oil-to-water ratio (OWR) of oil-based drilling fluids (OBDFs) to ultra-low levels (e.g., 55:45) exacerbates barite sag—a failure mode driven by barite’s inherent hydrophilicity and the weakened suspending capacity of the oil phase. Conventional low-molecular-weight wetting agents fail under these demanding conditions due to weak adsorption and thermal instability. In direct response to the solid-phase control challenge described above, we designed and synthesized a new hyperbranched polymeric wetting agent (HP-Wet) via a deliberate molecular topology strategy. The HP-Wet architecture incorporates phosphonate groups for robust anchoring onto barite surfaces and long alkyl chains to confer… More >
