Fabrication of PDMS-Stabilized porous silver films derived from recovered silver sources as flexible conductive materials

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 …

Discovery of anti-inflammatory compounds from the stem bark of Garcinia latissima

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 skin from fish gelatin-hyaluronic acid porous scaffold

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 …

One class self-organizing maps with Monte Carlo permutation for gemstone classification using Raman spectroscopy

Accurately identifying gemstones is important for authentication and quality control. In this study, we developed an artificial intelligence method that uses self-organizing maps (SOMs) combined with Monte Carlo testing to classify gemstones from their Raman vibrational patterns. The model was optimized for map size and training cycles, and its reliability was evaluated through repeated random …

Modified MOF catalysts: CO2 to value-added products

This research focuses on the design and modification of high surface area, porous materials known as metal-organic frameworks (MOFs). The objective is to utilize these materials as catalysts to convert carbon dioxide (CO2) into high-value cyclic carbonates, which are crucial for the polymer and battery industries. MOFs typically suffer from diffusion limitations because their pores …
