Research involving reactive silicone chemistry has focused on the production of pure silicon and hybrid materials, hydrosilylation, ring-opening and atom transfer polymerizations, polymerizations with controlled stereochemistry, and condensation reactions.
Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.

The soaring global demand for energy, coupled with the limited supply of fossil fuels, has increased the need for renewable, low-cost energy sources. Organic electronics have shown great promise for applications in lighting, power, and circuitry, with rapidly improving performance
HILIC mode chromatography using an Ascentis® Express OH5 resolved the majority of the acyl-L-carnitines tested. It may be possible to use MS/MS and particular fragment ions to resolve the two coeluting pairs.
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.
Immunohistochemistry (IHC) techniques and applications have greatly improved, dermatopathology is still largely based on H&E stained slides.This paper outlines ways in which IHC antibodies can be utilized for dermatopathology.
