Some physical properties of chitosan in propionic acid solutions [PDF]

open access: yesMaejo International Journal of Science and Technology, 2007
Surface tensions, contact angles and conductivities of propionic acid solutions containing different amounts of chitosan were measured at a room temperature to a temperature accuracy of 0.2. The value of critical coagulation concentration (CCC) was then

THE EFFECT OF TEMPERATURE AND MIXED-SOLVENT COMPOSITION ON THE INTRINSIC VISCOSITY OF GR–S

open access: yes, 1948
The intrinsic viscosity of a sample of GR–S has been measured, at temperatures ranging from 0° to 65 °C., in several solvents made progressively 'poorer' (to the point of precipitation) by the addition of nonsolvent.

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

open access: yesAdvanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

open access: yesAdvanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.
