Identification of some lipid peroxides by thin-layer chromatography
Journal of Lipid Research, 1965 Solvent systems are described which permit class separations of various peroxidized lipids by thin-layer chromatography. This procedure has proved useful in biological studies and for testing the deterioration of lipids.Proof is given that the least ...

Advanced Materials Interfaces, EarlyView.The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.

A modified procedure for thin-layer chromatography of phospholipids
Journal of Lipid Research, 1982 We have found that when lipid samples from a variety of tissues are run on EDTA-impregnated plates in a solvent system which contains a reduced amount of acetic acid and water compared with that used by Skipski et al. (1964. Biochem. J.

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells
Advanced Materials Technologies, EarlyView.Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Thin-layer chromatography as a method of control furan compounds in transformer oil
Известия высших учебных заведений: Проблемы энергетики, 2017 Thin-layer chromatography is one of the most common methods for the determination of furan derivatives in transformer oils. The article suggested improvement in the method by the use of thin-layer plates based on zeolite materials and a variety solvents ...

Enantioselective Total Synthesis of (—)-Acetylaranotin, a Dihydrooxepine Epidithiodiketopiperazine [PDF]
, 2012 The first total synthesis of the dihydrooxepine-containing epidithiodiketopiperazine (ETP) (−)-acetylaranotin (1) is reported. The key steps of the synthesis include an enantioselective azomethine ylide (1,3)-dipolar cycloaddition reaction to set the ...

Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics
Advanced Materials Technologies, EarlyView.Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and
