Polypyrrole-Coated Low-Crystallinity Iron Oxide Grown on Carbon Cloth Enabling Enhanced Electrochemical Supercapacitor Performance

Molecules, 2023
It is highly attractive to design pseudocapacitive metal oxides as anodes for supercapacitors (SCs). However, as they have poor conductivity and lack active sites, they generally exhibit an unsatisfied capacitance under high current density.

Separation of dolichol from dehydrodolichol by a simple two-plate thin-layer chromatography.

Journal of Lipid Research, 1992
A novel thin-layer chromatographic procedure was devised to separate dolichol and dehydrodolichol from each other with the concomitant separation of each family with respect to the carbon chain length.

Enzymatic conversion reactions of 5-hydroxymethylfurfural (HMF) to bio-based 2,5-diformylfuran (DFF) and 2,5-furandicarboxylic acid (FDCA) with air: mechanisms, pathways and synthesis selectivity

Biotechnology for Biofuels, 2020
Background 2,5-Furandicarboxylic acid (FDCA) is one of the top biomass-derived value-added chemicals. It can be produced from fructose and other C6 sugars via formation of 5-hydroxymethilfurfural (HMF) intermediate.

Peripheral chemical reactions

Chemical Physics Letters, 1993
Abstract Forward scattering of the products of direct exoergic atom transfer reactions is proposed as an indication for a peripheral attraction: a reaction in which an atom at the periphery of the reactants is abstracted. Model computations for the O( 1 D) + N 2 O reaction are used to illustrate the proposed mechanism. The opacity function has a peak
