Off-grid water pumping systems (OGWPS) have become an increasingly popular area of research in the search for sustainable energy solutions. This paper presents a finite element method (FEM)-based design and analysis of Brushless-DC (BLDC) and Switched Reluctance Motors (SRM) designed for low-power water pumping applications. Utilizing adaptive finite element analysis (FEA), both motors were designed with identical ratings and design parameters to ensure a fair comparison.

Due to the high cost of the available Pt electrocatalysts, the large-scale water electrolysis production of hydrogen has been hindered. Hydrogen generation via electrochemical water splitting is a renewable energy essential to a sustainable society, creating a distinct material interface that shows Pt-like properties with long-term stability crucial to hydrogen evolution reactions (HERs). Here, we synthesized the guanine-assisted facile synthesis of 1 wt % Pt/MoC/C having a layered type morphology via solid state calcined process followed by chemical reduction.

Food waste offers a potential source for bioethanol production, but productivity depends on the chemical composition of the raw materials and the processes involved. However, assessment of the environmental sustainability of these processes is often absent and can be carried out using the Life Cycle Assessment (LCA) methodology. This study aimed to perform an LCA on bioethanol production from mixtures of different wastes, including tubers, fruits, and processed foods, focusing on the gate-to-gate phase.

Breast cancer is a multifaceted and prevalent malignancy, impacting a considerable proportion of women globally. Numerous signaling pathways intricately regulate cellular functions such as growth, proliferation, and survival. Among the various regulators, lncRNAs have emerged as significant players despite their inability to encode proteins.

Tear trough deformity (TTD) is a significant cosmetic concern, with current treatments relying primarily on invasive injectable fillers, which are costly and carry risks of complications. Despite the widespread use of hyaluronic acid (HA) in cosmetic applications, its poor dermal permeation has limited the development of effective topical fillers for TTD.This study aim to develop and evaluate a novel hyaluronic acid nanogel (nanofiller, NF) as a non-invasive topical filler for TTD.
