Green and Controllable Synthesis of Au–Ag Bimetal Nanoparticles by Xylan for Surface-Enhanced Raman Scattering

ACS Sustainable Chemistry and Engineering, 2019
In surface-enhanced Raman scattering, Ag nanoparticles are broadly employed. However, their lack of oxidation resistance means that their performance diminishes and is difficult to repeat. In this study, with addition of xylan, Au–Ag core–shell and alloy

Cationisation of galactomannan and xylan hemicelluloses

Carbohydrate Polymers, 2011
In this study, the cationisation of galactomannan and xylan hemicellulose types was investigated with 2,3-epoxypropyltrimethylammonium chloride (ETA) as reagent, under alkaline conditions. The degree of substitution was accurately determined by H-1 NMR spectroscopy after hydrolysis in a DCl/D2O mixture and confirmed by elemental analyses. The influence

Eucalyptus xylan: An in-house-produced substrate for xylanase evaluation to substitute birchwood xylan

Carbohydrate Polymers, 2018
Over the past decades, most studies with xylanases have used Birchwood xylan as the standard substrate for activity assays. However, recently, Birchwood xylan production was discontinued by major suppliers, creating an important demand for a substitute.

The kinetics of xylan pyrolysis

Thermochimica Acta, 1980
Abstract The study concerned itself with the investigation of the kinetics of xylan in an inert atmosphere. It was found that there were two basic mechanisms for degradation in the temperature range studied, nucleation and diffusion. The range of temperatures studied was 200–290°C.
