Polarographic Determination of Vinyl Compounds
BUNSEKI KAGAKU, 1955 Polarographic determination of several vinyl compounds have been investigated with the use of tetramethylammonium ion, (CH3)4N+, and tetrabutylammonium ion, (C4H9)4N+, as the supporting electrolytes. The vinyl esters, such as vinyl acetate, vinyl butylate, and vinyl benzoate, can be determined from the wave of acetaldehyde which is produced by the ...

Advanced Healthcare Materials, EarlyView.Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]
, 2016 The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.

A tale of two reductases: extending the bacteriochlorophyll biosynthetic pathway in E. coli.
PLoS ONE, 2014 The creation of a synthetic microbe that can harvest energy from sunlight to drive its metabolic processes is an attractive approach to the economically viable biosynthetic production of target compounds.

Palladium Catalyzed Reactions of 2-Nitroaniline with Vinylethers
E-Journal of Chemistry, 2007 A new method for the synthesis of hemiaminal ether have been suggested. The reactions of 2-nitro aniline with vinyl ether in the presence of PdCl2(CH3CN)2 produces hemiaminal ether compounds. The resulting products have been identified by spectral data.

Advanced Healthcare Materials, EarlyView.Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...
