Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

CuO‐CuAl2O4 Catalyst for Synthesis of 1‐Methylindole by Alcohol Amine Method

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cu‐based catalysts used for the vapor‐phase synthesis of 1‐methylindole from N‐methylaniline and ethylene glycol are prone to Cu sintering and deactivation under the reaction conditions. In this work, CuO‐CuAl2O4 catalysts were prepared by a coprecipitation method and applied to the synthesis of 1‐methylindole via alcohol amine route.

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Comparative Study of High Voltage Spinel∥Lithium Titanate Lithium‐ion Batteries in Ethylene Carbonate Free Electrolytes

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
FEC and sulfone‐based co‐solvents are investigated as EC‐free electrolytes for LNMO∥LTO cells. FEC‐containing electrolytes demonstrate enhanced electrochemical stability by stabilizing the CEI and SEI layers, mitigating transition metal migration. Conversely, sulfone electrolytes form thinner CEIs and thick, sulfur‐rich SEIs, which are less effective ...
