Copper indium gallium selenide (CIGS) thin-film solar cells remain among the most promising photovoltaic technologies due to their high absorption coefficient, tunable bandgap, and compatibility with low-temperature processing. This manuscript presents a comprehensive numerical investigation of performance enhancement strategies for CIGS-based solar cells using one-dimensional and multidimensional simulation frameworks. Device optimization is analyzed by systematically varying absorber composition, bandgap grading, [...]

Integrating Life Cycle Cost (LCC), Life Cycle Assessment (LCA), and Social Life Cycle Assessment (S-LCA) has emerged as a pivotal approach for evaluating the multi-dimensional performance of construction materials. However, existing studies often treat these dimensions in isolation, failing to provide a holistic representation of sustainable development. Furthermore, while material selection in the preliminary design phase fundamentally dictates the sustainability trajectory of a project, there remains a critical r [...]

Worldwide, the incidence of allergenicity is rising rapidly, making it an ongoing clinical challenge and public health concern. The current treatment options for allergies include allergen avoidance, medications to improve symptoms, and immunotherapy to desensitize affected individuals to specific allergens. However, these approaches have limitations, and there is an urgent need for novel and more effective therapies. Allergies are a compelling candidate for gene editing (GE) given their prevalence and the inadequa [...]

The textile industry is a major source of environmental pollution due to the discharge of highly colored and chemically complex wastewater containing toxic, mutagenic, and carcinogenic compounds that are often resistant to conventional treatment. Although conventional chemical coagulants and flocculants such as alum and synthetic polymers are effective, their application raises concerns about excessive sludge generation, residual toxicity, and long-term environmental impacts. This short review critically evaluates [...]

A new series of bis-quadridentate ligands (L1-L3) and their corresponding zinc(II) complexes (Complex 1-3) were rationally designed, synthesized, and characterized. The ligand framework features multiple donor sites that enable stable coordination to zinc(II), yielding well-defined metal complexes. The structures of the synthesized compounds were confirmed using a combination of analytical and spectroscopic techniques. Thermal gravimetric analysis revealed that all zinc complexes exhibit exceptional thermal stabili [...]

Molecular dynamics is an essential tool for studying the formation of surface patterns in their early stages under low-energy bombardment. Recently, it has been shown that semiconductor surfaces such as Si can reorganize under ultra-low-energy conditions to form surface patterns. In this work, we investigate the formation of patterns on metal surfaces under these conditions. To accelerate the process, a longitudinal substrate model was employed, with clusters selected as projectiles. As is well known, pattern forma [...]

This study explores the use of plant extract to reduce corrosion on low-carbon steel reinforcement embedded in concrete. It is globally known that structures exposed to corrosive environments can collapse due to deterioration of the steel rods embedded in the concrete. The corrosion-inhibition potential of leaves, bark, and root extracts of Boswelia dalzelia (BD) on concrete reinforcement was investigated using a half-cell potentiometer and scanning electron microscopy (SEM) analysis. The half-cell potential readin [...]

This work addresses the application of a method to examine the spatial extent of ecological resources and green space on small Department of Energy (DOE) sites and comparison to ecological resources and green space in the surrounding region. Increasingly, governmental regulators, resource trustees, and the public are concerned that federal facilities are protecting human health and the environment, including ecological resources on their sites. This paper uses the National Land Cover/Land Use Database to examine an [...]

Effective thermal management in polymeric materials still represents a considerable challenge for emerging applications, such as wearable electronics, soft robotics, and sustainable composite systems, wherein flexibility and environmental compatibility are of utmost importance. This research utilizes non-equilibrium molecular dynamics (NEMD) simulations to examine interfacial thermal resistance (ITR) and effective thermal conductivity (keff) in bio-based PBS-ENR-PBS trilayer systems. Two varieties of epoxidized nat [...]

In bottling companies, spur gears play a vital role in ensuring efficient mechanical power transmission in bottling machines. Therefore, the maintainability of spur gears in these machines is important because it directly affects the overall efficiency, productivity, and cost-effectiveness of bottling operations. The study focused on data collection for different tasks performed on a failed gear from January to December of a particular year based on task time and frequency of occurrence, which are important factors [...]
