The Effects of Enzyme Pretreatment Extraction on Lipid Recovery With Normal Phase HPLC

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT With the increasing interest in the commercialization of microalgal fermentation‐based products, sustainable and efficient oil extraction methods have been developed for manufacturing and analytical testing. Due to the variability and resilience of micro‐algae cell walls, traditional lipid extraction methods such as Folch and Bligh and Dyer ...

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Changing a Winning Team—Replacement of Brominated Flame Retardant and Antimony Trioxide in Acrylonitrile–Butadiene–Styrene

Journal of Applied Polymer Science, EarlyView.
This comprehensive study investigates reducing the amount of brominated flame retardant (Br) and/or antimony trioxide (ATO) in acrylonitrile–butadiene–styrene. Therefore, condensed‐phase flame‐retardant mechanisms are introduced into the flame‐inhibition system.
