The stereochemistry of acenaphthylene glycols [PDF]
, 1937 The preparation of acenaphthylene from acenaphthene has been carried out under varying conditions, and a maximum yield of about 50% has been obtained. From acenaphthylene the acenaphthylene glycols have begin prepared by way of the dibromides.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Glycols Partitioning At High Pressures In Gas Processing Systems
, 2017 Glycols are commonly used chemicals in the gas processing industry, for example monoethylene glycol is (MEG) injected at the well head to prevent hydrate formation; glycols are also used in dehydration units to remove water from natural gas streams ...

THE ACTIVATION OF PURIFIED HUMAN PLASMINOGEN IN SOLUTIONS OF ETHYLENE GLYCOLS
, 1963 Ethylene glycols have been found to allow activation of purified preparations of human plasminogen. The activity of the enzyme formed, plasmin, was measured using TAMe (p-toluene-sulphonyl-L-arginine methyl ester) as a substrate.

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 ...
