On‐Demand Chemically Degradable Hydrogels for Biological Applications
ChemBioChem, Volume 27, Issue 6, 27 March 2026.This review explores the mechanisms and kinetics of chemically induced on‐demand degradation in hydrogels designed for painless dressing removal and traceless dissolution across various biological applications. Covalent bond cleavage and noncovalent disruption triggers are compared, highlighting opportunities for load‐bearing scaffolds with faster ...

Enantioselective Growth of Chiral Serine‐Induced β‐Ag2Se Crystals from an Organoselenium Compound
Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.Chiral amino acids direct the enantioselective crystallization of β‐Ag2Se nanocrystals from an organoselenium precursor. L‐ and D‐serine induce distinct morphologies and opposite homochiral adsorption preferences, transferring molecular handedness into the inorganic lattice.

Laser Raman spectra of semicarbazide hydrobromide
, 1981 Semicarbazide hydrobromide which is isomorphous with SEM.HCl, was expected to belong to a new family of ferroelectrics. Dielectric, thermal and other studies on these crystals have yielded results which show many peculiarities but not confirmed ...

Some semicarbazide derivatives and their antimicrobial activity
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1993 Various semicarbazides and thiosemicarbazides (1-5) and their cyclised products, triazoles, oxadiazoles and thiadiazoles (6-9) have been reported to possess antibacterial, antitubercular and antifungal activities. Based on these findings it w as of interest to prepare some new arylsemicarbazide and arylthiosemicarbazide derivatives and to evaluate ...

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds
ChemMedChem, Volume 21, Issue 2, January 2026.Representative functional groups known for urease inhibition are reviewed within diverse scaffolds using structure–activity analyses to identify features associated with high inhibitory activity. Urease is a metalloenzyme produced by a wide range of organisms and plays a critical role in nitrogen microbial metabolism by catalyzing the hydrolysis of ...

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.High‐consistency silicone rubbers can be foamed with various chemical and physical blowing agents. However, due to the toxic and, therewith, harmful effects of chemical blowing agents, physical blowing agents are becoming increasingly important. In this thesis, the influence of the viscosity adjusted via the silica content of different high‐consistency

Convulsant Effects of Semicarbazide in Epileptic Monkeys.
Experimental Biology and Medicine, 1956 Summary(1) Threshold convulsant dosages to rapid intravenous injection of semicarbazide were significantly lower in chronically epileptic monkeys than in normal unoperated controls. (2) Clinical seizures following intravenous injection of threshold convulsant doses of semicarbazide occurred after a latent period of 2 to 3 1/2 hours. With suprathreshold
