Abstract: Molecular machines stand as an enthralling frontier where chemistry, physics, and material science converge, unravelling the fundamental principles governing molecular behaviour and functionality. These intricately designed structures, constructed from individual molecules, exhibit mechanical-like movements and functions at the molecular scale, akin to their macroscopic counterparts but on a significantly smaller level. Rooted in principles of molecular recognition, conformational changes, and energy transduction, these machines dynamically respond to external stimuli, facilitating tasks such as molecular transport, switching, and mechanical work.......

Abstract: Majority of rural Africans use inefficient energy sources like wood and fossil fuels, which are not environmentally friendly and hazardous to human health. Bioethanol is an alternative clean source of energy that can be obtained from biomass and other agricultural wastes. Producing bioethanol from agricultural wastes cleans up the environment as it prevents the cutting of trees for wood fuel, thus solve the problem of de- forestation. It also gives farmers an additional source of income from otherwise wasted agricultural materials, reduces indoor pollution, and.......

Abstract: Performance-enhancing drugs (PEDs) have spread throughout many sports, often tainting the spirit of competition. PED use among athletes is reported at varying frequencies, ranging from 5 to 31%. What's more, some of these drugs seriously endanger the health and safety of sportsmen. Human growth hormone, creatine, erythropoietin and blood doping, amphetamines and stimulants, and beta-hydroxy-beta-methylbutyrate are examples of common......

Abstract: Water scarcity and pollution are major challenges in the world today. The major water pollutants include heavy metals, pesticides, dioxins, furans, phenolics, and dyes. Consumption of these pollutants triggers the emergence of diseases, including cancer in both humans and animals. Dyes are colored pollutants that hinder photosynthesis and increase the biochemical oxygen demand (BOD) by preventing the penetration of light in water. They get into the water bodies through the disposal of untreated and partially treated wastewater by agricultural and industrial processes. Therefore, there is a need for an affordable and effective technique for water treatment. Adsorption is proven to be the superior technique compared to the others, as it is easy to design, reusability, and effectiveness in removing a wide range of pollutants from aqueous solutions. The adsorbents used should be abundant, affordable, and with the desired adsorption properties. In addition, they should be porous, with high specific surface......

Abstract: This study investigated the potential of a dye extract from the Cola acuminata seeds to inhibit corrosion of mild steel in Hydrochloric acid (1M HCl). A combined approach using experiments and theoretical calculations (quantum chemistry) was employed. Weight loss, electrochemical techniques, and computer modeling were used to assess the extract's effectiveness. Adsorption and thermodynamic properties were examined to understand how the extract interacts with the metal surface. Increasing the extract concentration significantly improved its ability to prevent corrosion......
