Characteristic infrared frequencies of rotational isomers of alkyl chlorides [PDF]
, 1962 A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond.

Acta Crystallographica Section E Structure Reports Online, 2009 The title compound, C(4)H(10)N(+)·Cl(-), was obtained as a decomposition product from 2,6-bis-(pyrrolidin-yl)pyridine. The anion lies on the same cristallographic mirror plane as the N atom of the cation, the complete cation being generated by mirror symmetry.

Workplace Health & Safety, 2017 Methylene chloride is an industrial solvent used in commercial paint strippers and degreasing agents. This chemical is widely used in consumer products, yet without appropriate protections, exposure may lead to death. Already banned in some countries, the Environmental Protection Agency (EPA) recently proposed limiting its use in the United States.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Synthesis and applications of alkenyl chlorides (vinyl chlorides): a review. [PDF]
Beilstein J Org ChemInternational audienceAlkenyl chlorides constitute a synthetically valuable yet historically underexplored class of organohalides. First prepared in 1868 by Charles Friedel - best known for the Friedel-Crafts reaction - via the reaction of ketones with ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
