Abstract:
... The backbone of Dendrobium officinale polysaccharide (DOP) was reported to be glucomannan. But the dispute continues due to the limitation of conventional analysis methods (e.g., the overlapped NMR signals). Herein, we describe an oligosaccharide sequencing analysis that successfully corrects the backbone to mannan. This analysis involves producing oligosaccharide fragments from mild acid hydrolys ...

Abstract:
... Rapid production of nanoscale carbon-based designs with complex 3D geometry has been recently enabled by nano-3D printing via two-photon polymerization (2PP) combined with post-pyrolysis of the printed polymer. Upon pyrolysis, the design is converted to predominantly carbon, but it remains critical to select the appropriate 2PP printing parameters to produce a high stiffness and strength carbon ma ...

Abstract:
... 2D MXenes (transition metal carbides, Ti₃C₂Tₓ) with large surface area and metallic conductivity are widely used as supporters in catalysts. Unfortunately, the single MXene sheets would deteriorate in the presence of oxygen and water, which is almost the same as the environment of oxygen reduction reaction (ORR). Herein, an “armor” was constructed to encapsulate the oxidizable MXene by a confined ...

AMase-treated starch (ATS) showed an increase in weight-average molecular weight (Mw) at a short reaction time, and the action mode of AMase revealed two trends separated by the E/S. At high E/S (≥2 U/g), Mw increas ...
