Partially Renewable Poly(butylene 2,5-furandicarboxylate-co-isophthalate) Copolyesters Obtained by ROP

New Hydrogel obtained by Chitosan and Dextrin-VA Co-polymerization

Introduction Hydrogels are a class of three-dimensional, highly hydrated polymeric networks (1). They are suitable for biomedical applications because of their high tissue compatibility mainly caused by the high water content of the gels (2). Chitosan (CS) (poly[β-(1-4)-2-amino-2-deoxy-Dglucopyranose]) is a non-toxic and biocompatible copolymer of N-glucosamine and N-acetyl-glucosamine produced...

Characteristics of Biochar Obtained by Hydrothermal Carbonization of Cellulose for Renewable Energy

The effect of hydrothermal carbonization on the properties of cellulose present in lignocellulosic biomass was investigated for converting it into a renewable energy resource with high energy recovery efficiency. The biochar obtained from cellulose subjected to hydrothermal carbonization showed a significant increase in its carbon content and a calorific value. 13C NMR spectroscopy showed that ...

Allocation of Partially Renewable Resources -concept, Models and Applications

Enterprises facing pressure to reduce costs and to make better use of existing staff or equipment can, at least in part, meet this pressure by more efficient and intelligent planning; methods for this task lie at the heart of management science and operations research. Successful application of such methods depends on unambiguous model formulations; these in turn call for expressive modelling c...

Biodegradation of new series of aliphatic copolyesters by fungi

Biodegradable aliphatic random copolyesters poly(butylene succinate-co-butylene adipate), PBSA and poly(butylene succinate-co-butylene azelate), PBSAz were synthesized from 1,4 butane diol, succinic acid and adipic acid/azelaic acid through direct melt polycondensation with Titanium Tetra isopropoxide (TTiPO) as a catalyst. These polyesters were characterized by Viscosity measurements, 1H NMR s...
