A NOTE ON THE STABILITY OF SOME SUBSTITUTED SEMICARBAZIDES

open access: yes, 1945
Recently Baker and Gilbert (J. Amer. Chem. Soc, 1942, 64, 2777) have studied the kinetics of the transformation of hydrazine cyanate into semicarbazide and also of the conversion of semicarbazide into hydrazine cyanate.

On‐Demand Chemically Degradable Hydrogels for Biological Applications

open access: yesChemBioChem, 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

open access: yesAdvanced 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.

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds

open access: yesChemMedChem, 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 ...

Some semicarbazide derivatives and their antimicrobial activity

open access: yesCommunications, 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 ...

Influence of Material Viscosity on the Properties of Extruded High‐Consistency Silicone Rubber Foam Profiles

open access: yesAdvances 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
