Contributors: X. Zhang n, S. Khan n, C. Saquing n & L. Ji n

TL;DR: PAN nanofibers obtained from composite fibers with higher silica contents exhibited more nonuniform surface morphology, and the Brunauer-Emmett-Teller (BET) surface area of porous PAN nan ofibers made from PAN/silica (5 wt%) composite precursors is higher than that of pure nonporous PAN nanofibia.

Rheological properties of guar galactomannan solutions during hydrolysis with galactomannanase and alpha-galactosidase enzyme mixtures

BIOMACROMOLECULES, 8(3), 949–956.

By: S. Mahammad n, D. Comfort n, R. Kelly n & S. Khan n

MeSH headings : Carbohydrate Conformation; Galactans / metabolism; Galactose / analogs & derivatives; Hydrogen-Ion Concentration; Hydrolysis; Kinetics; Mannans / chemistry; Mannans / metabolism; Mannose / chemistry; Mannosidases / chemistry; Models, Chemical; Models, Statistical; Plant Gums / metabolism; Polysaccharides / chemistry; Rheology / methods; Time Factors; alpha-Galactosidase / chemistry
TL;DR: A rheology-based kinetic model is developed to estimate the reaction rate constants and interpret synergistic effects of multiple enzyme contributions and reveals that both the native and the debranched guar have the same activation energy for beta-mannanase action, although debranching considerably increases the frequency of enzyme-guar interactions.

Viscoelastic behavior of cellulose acetate in a mixed solvent system

MeSH headings : Acetamides / chemistry; Cellulose / analogs & derivatives; Cellulose / chemistry; Elasticity; Gels / chemistry; Hydrogen Bonding; Rheology; Solvents / chemistry; Viscosity; Water / chemistry
TL;DR: The changes in dynamic rheological behavior of the system during gelation correlate well with the combined solubility parameter (delta) and, in particular, the Hansen hydrogen-bonding solubilities parameter index ( delta(h)) of the solvent system, suggesting hydrogen- bonding interactions may be the major route initiating the sol-gel process.

MeSH headings : Amides / chemistry; Cross-Linking Reagents / chemistry; Lactoglobulins / chemistry; Models, Molecular; Protein Conformation; Protein Structure, Secondary; Sensitivity and Specificity; Spectroscopy, Fourier Transform Infrared / methods; Transglutaminases / chemistry
TL;DR: The changes in the C-H stretching region clearly indicate that hydrophobic interactions are altered upon enzymatic cross-linking by transglutaminase, and denaturing by thermal treatment dissociates the beta-sheets in the native structure, leading to new intermolecular beta- sheets being formed.

TL;DR: A new mathematical model based on Michaelis Menten (MM) kinetics is developed to predict the changes in molecular weight distribution (MWD) during the enzymatic depolymerization of guar galactomannan, and analyses confirm that an increase in PDI during the depolymersization is not necessarily due to nonrandom scission, as previously concluded.
