N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis
Advanced Synthesis &Catalysis, EarlyView.Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Promiscuous, non-catalytic, tandem carbohydrate-binding modules modulate the cell-wall structure and development of transgenic tobacco (Nicotiana tabacum) plants [PDF]
, 2007 We have compared heterologous expression of two types of carbohydrate binding module (CBM) in tobacco cell walls. These are the promiscuous CBM29 modules (a tandem CBM29-1-2 and its single derivative CBM29-2), derived from a non-catalytic protein1 ...

Structure of Hardwood Xylan and Specificity ofStreptomyces β-Xylanase toward the Xylan [PDF]
Bioscience, Biotechnology, and Biochemistry, 1994 Three kinds of xylo-oligosaccharides having structures of 3(2)-beta-xylosylxylobiose, 3(2)-beta-xylobiosylxylobiose, and 2(2)-beta-xylobiosyl-xylobiose were isolated from an enzymatic hydrolysate of hardwood xylan with Streptomyces beta-xylanase. The structures suggest that the hardwood xylan has both (1-->2)- and (1-->3)-beta-D-xylopyranosyl linkages ...

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.
