This study reports a sustainable Ni–Mo bimetallic catalyst supported on zirconium-modified SBA-15 for selective hydrogenation of fatty acids to high-value fatty alcohols. The catalyst enables nearly complete conversion of oleic acid to octadecanol under mild conditions and demonstrates excellent stability and recyclability. It offers a greener, cost-effective alternative to noble-metal catalysts for producing bio-renewable chemicals …

This study presents a simple and efficient method for making flexible conductive materials by forming porous silver films on a PDMS substrate. Silver is first converted into silver acetate through a green acetoxylation process using ethyl acetate, and then thermally decomposed to create a porous silver layer. We tested different silver sources, including pure silver …

Garcinia latissima Miq. has been traditionally used by local communities in Indonesia for wound healing and to relieve itching. A phytochemical investigation of the stem bark of G. latissima led to the isolation of tocotrienol and triterpenoid derivatives, including previously undescribed metabolites. Among the isolates, (20R)-eupha-8,25-diene-3β,24ξ-diol suppressed nitric oxide production in LPS-stimulated RAW 264.7 cells …

Artificial three-dimensional (3D) skin has been used as an alternative material for toxicity testing, studying skin diseases, and skin tissue engineering. The 3D skin can be fabricated using supporting materials that facilitate cell attachment, promote nutrients and air permeation, and eventually accommodate 3D cellular construction. Herein, fish gelatin-hyaluronic acid porous scaffold were employed as the …
