Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and

Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...
