New fused triazinium systems from (alkoxycarbonyl)azinium N-aminides [PDF]
, 2007 2-(Alkoxycarbonyl)cycloimmonium N-aminides are efficient 1,4-dipoles that react with different types of reagents such as carbodiimides, benzoyliso(thio)cyanates and heterocyclic imidoyl chlorides to give new heterobetaines containing fused [l,2,4 ...

Further studies on the iodine concentration of conventional, organic and UHT semi-skimmed milk at retail in the UK [PDF]
, 2017 Milk is the largest source of iodine in UK diets and earlier studies showed organic summer and winter milk to be significantly lower in iodine than conventional milk. One study also showed UHT milk to have lower iodine concentration.

Synthesis of N-Fmoc-ProtectedAmino Alkyl Thiocyanates/Selenocyanates and their Applicationin the Preparation of 5-Substituted S/Se-Linked Tetrazoles [PDF]
, 2011 A novel class of N-Fmoc-protected amino alkyl thiocy- anates/selenocyanates has been prepared by thiocyanation/seleno-cyanation of the corresponding alkyl iodides. These thiocyanates/selenocyanates undergo a facile [2+3]-cycloaddition reaction

Theory of Chiral Order in Random Copolymers
, 1995 Recent experiments have found that polyisocyanates composed of a mixture of opposite enantiomers follow a chiral ``majority rule:'' the chiral order of the copolymer, measured by optical activity, is dominated by whichever enantiomer is in the majority ...

Synthesis of Cyanate Esters Based on Mono-O-Methylated Bisphenols with Sulfur-Containing Bridges
Molecules, 2019 We described a synthetic approach to bisphenol-based monocyanate esters based on mono-O-methylation of parental bisphenols followed by cyanation of the residual phenolic hydroxyl. Structures of the synthesized compounds were determined by the application

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
