The Isolation and Spectroscopic Characterization of Products from the Metatheses of Alkyl Oleates [PDF]
The products from the metathesis reactions of methyl and ethyl oleate were isolated using column chromatography. The various components obtained were characterized using infrared (IR), 1Hand 13C nuclear magnetic resonance spectroscopy (NMR) and gas ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Isotope Ratio Monitoring Gas Chromatography Mass Spectrometry (IRM-GCMS) [PDF]
On Earth, the C-13 content of organic compounds is depleted by roughly 13 to 23 permil from atmospheric carbon dioxide. This difference is largely due to isotope effects associated with the fixation of inorganic carbon by photosynthetic organisms.

Real-time 2D separation by LC × differential ion mobility hyphenated to mass spectrometry [PDF]
The liquid chromatography-mass spectrometry (LC-MS) analysis of complex samples such as biological fluid extracts is widespread when searching for new biomarkers as in metabolomics.

This study explores a cost‐effective alternative by incorporating oxophilic dopants into non‐precious metal hosts to enhance water dissociation and catalyst stability. Computational screening identified Ni─V, Ni─Mo, and Co─V as top candidates. Subsequent experiments confirmed Ni20V exhibits superior HER activity, achieving 76 mV lower overpotential ...

The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...
