Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

The synthesis diagnostic test systems on the basis of polymer microspheres in the presence of polyvinylpyrrolidone modified with an amino acid

Тонкие химические технологии, 2010
Styrene-divinylbenzene particles (6 microns in diameter) with carboxyl groups on the surface have been synthesized by seed polymerization in the presence of an organosilicon carboxyl-containing surfactant soluble in the monomer phase.

DFT Study of Binding and Electron Transfer from a Metal-Free Dye with Carboxyl, Hydroxyl, and Sulfonic Anchors to a Titanium Dioxide Nanocluster

International Journal of Photoenergy, 2013
We report results of density functional theory (DFT) calculations of a metal-free dye, 5-(4-sulfophenylazo)salicylic acid disodium salt, known as Mordant Yellow 10 (MY-10), used as sensitizer for TiO2 dye-sensitized solar cells (DSSCs).

An Ultrafast Self‐Gelling Versatile Hydrogel for Rapid Infected Burn Wound Repair in Military Medicine

Advanced Functional Materials, EarlyView.
A self‐gelling PG@PAC (POD/Gel‐CDH@PA/CHX) powder is developed for infected burn care in austere settings. Upon contact with wound exudate, it instantly forms an adhesive hydrogel, providing simultaneous hemostasis, broad‐spectrum antibacterial activity, reactive oxygen species scavenging, and immunomodulation. In a murine model of S.

PRODUCTION OF NANOCELLULOSE FROM NATIVE CELLULOSE – VARIOUS OPTIONS UTILIZING ULTRASOUND

BioResources, 2011
In this study three different ways of applying ultrasound for the production of nanocellulose from native cellulose were explored. In the first option bleached hardwood kraft pulp was oxidized with the ultrasound (US) assisted TEMPO/NaBr/NaOCl-system (US-

The reactivity of carboxyl groups in chymotrypsinogen

FEBS Letters, 1969
Recent work from this laboratory reported the functional and structural consequences of the modification of carboxylates in chymotrypsinogen (ChTg), chymotrypsin (ChTi), trypsinogen (Tg) and trypsin (Ti) [l] with glycine ethyl ester (GEE) under the influence of l-ethyl ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Reactivity of carboxyl groups in modified proteins [PDF]

FEBS Letters, 1971
The reactivities of carboxyl groups to carbodiimides in non‐reduced, S‐carboxymethyl, and S‐cyanoethyl proteins have been compared. When disulphide bonds are split, a decrease in reactivity was found, relatively minor in the S‐carboxymethyl derivative and almost complete loss of reactivities in the S‐cyanoethyl derivative.
