Abstract

Mild steel has tendency to form a protective film in caustic environments; however, elevated temperatures and freshly exposed metal surfaces usually prevent stable film formation—leading to rapid and active corrosion rate of mild steel. This study reports the potential of using ethanol extract of African peach leaf as alternative corrosion inhibitor of mild steel in 1.0 M NaOH solution. Gravimetric and electrochemical measurements were carried to unravel the mechanisms of the corrosion reduction [...]

Performance Enhancement of CIGS Thin-Film Solar Cells through Numerical Modeling

Damir Istamov and

Asliddin Komilov

Received: 04 March 2026; Published: 16 June 2026; doi: 10.21926/rpse.2602011

Abstract

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 compositi [...]

Received: 06 January 2026; Published: 04 June 2026; doi: 10.21926/rpse.2602010

Abstract

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 [...]

Applications of CRISPR-Cas9 Gene Editing Technology in Food Allergy Therapy: A Comprehensive Review

Ahmad M. Khalil

Received: 06 January 2026; Published: 29 May 2026; doi: 10.21926/rpse.2602009

Abstract

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 prevale [...]

Abstract

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 c [...]

Rajendrasinh N. Jadeja

Received: 12 February 2026; Published: 30 April 2026; doi: 10.21926/rpse.2602007

Abstract

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 re [...]

Received: 04 March 2026; Published: 24 April 2026; doi: 10.21926/rpse.2602006

Abstract

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 [...]

Abstract

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) [...]
