Measurement of 5,8,11, 14-icosatetraynoic acid in plasma by gas-liquid chromatography

Journal of Lipid Research, 1981
A gas-liquid chromatography-flame ionization detection method is described for measuring plasma levels of eicosatetraynoic acid using eicosatriynoic acid as an internal standard. The technique is simple, rapid, and reproducible. Eicosatetraynoic acid and

Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

Carbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.
