Mechanistic Control of Cathode–Electrolyte Interphase Formation in Gel Polymer Electrolyte for Lithium‐Ion Batteries

open access: yesAngewandte Chemie, EarlyView.
To regulate a distinct degradation pathway introduced by residual monomers in in‐situ gel polymer electrolytes (GPEs), tris(4‐fluorophenyl)phosphine (TFPP) is coupled with a voltage hold (VH) protocol. TFPP first covers the high‐Ni cathode surface and then preferentially decomposes during the hold step, forming a cathode–electrolyte interphase (CEI ...

SYNTHESIS OF TRIMETHYLOLPROPANE ESTER BASED ON CHICKEN FAT AS BIOLUBRICANTS

open access: yesRevista Mexicana de Ingeniería Química, 2018
In this project, chicken fat was transesterificated to methyl esters of chicken fat (MECF) with an efficiency of 80%, subsequently added trimethylolpropane (TMP) to get as majority product esters of trimethylolpropane (biolubricants). Temperature, molar ratio MECF:TMP and catalyst were evaluated using a mixed-level factorial design.

Enzymatic Synthesis of a Polyol Ester from Levulinic Acid and Trimethylolpropane and Its Tribological Behavior as Potential Biolubricant Basestock

open access: yes, 2020
In this study, a polyol ester from levulinic acid (LA) and trimethylolpropane (TMP) was synthesized by enzymatic catalysis in a solvent-free system. The total conversion of TMP reached up to 84% on average after lipase recycling for five times.
