Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Blood Compatibility of Oxidized Bacterial Cellulose/Silk Fibroin Composite Membrane

open access: yes, 2015
In this work, the oxidized bacterial cellulose (BC) was modified by silk fibroin (SF) to improve its blood compatibility. The oxidized BC pellicles were added to the aqueous silk fibroin solution containing crosslinking agents at room temperature for ...

CXCL16 and oxLDL are induced in the onset of diabetic nephropathy

open access: yes, 2009
Diabetic nephropathy (DN) is a major cause of end-stage renal failure worldwide. Oxidative stress has been reported to be a major culprit of the disease and increased oxidized low density lipoprotein (oxLDL) immune complexes were found in patients with ...

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

open access: yesAdvanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

Formation of Carbonyl and Carboxyl Groups on Cellulosic Pulps: Effect on Alkali Resistance

open access: yesBioResources, 2014
Ozone bleaching generates carbonyl groups on the cellulose polymer when applied to unbleached kraft pulps. This suggests that pulp fully bleached with a totally chlorine-free (TCF) sequence may contain more oxidized groups than standard elemental ...
