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.

Surfactant-Mediated Modulation of Hydrophobic Interactions in Associative Polymer Solutions Containing Cyclodextrin

LANGMUIR, 25(2), 794–802.

By: S. Talwar n, J. Harding n, K. Oleson n & S. Khan n

MeSH headings : Cyclodextrins / chemistry; Hydrophobic and Hydrophilic Interactions; Molecular Structure; Polymers / chemistry; Rheology; Solutions; Surface-Active Agents / chemistry; Viscosity
TL;DR: The ability of nonionic surfactants to modulate the rheological characteristics of comblike hydrophobically modified associative polymer solutions containing cyclodextrin (CD) is examined and it is revealed that the extent and rate of recovery of zero shear viscosity as well as dynamic moduli are strongly influenced by the type of CD (alpha versus beta) aswell as the HLB of the surfactant.

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.

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.

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.

INTERNATIONAL JOURNAL OF BIOLOGICAL MACROMOLECULES, 31(1-3), 37–44.

By: M. Burke n, S. Ha n, M. Pysz n & S. Khan n

author keywords: whey protein; rheology; gels; enzyme; low pH
MeSH headings : Dose-Response Relationship, Drug; Enzymes / chemistry; Hot Temperature; Hydrogen-Ion Concentration; Plant Proteins / chemistry; Proteins / chemistry; Temperature; Time Factors; Transaminases / chemistry
TL;DR: Dynamic rheological measurements reveal that the gel elastic modulus and yield stress increase substantially when heat treatment is supplemented with enzyme treatment, which leads to two types of gel microstructure at short and long enzyme treatment times, with the extent of enzyme diffusion modulating the structure at intermediate times.
