Čudesna molekula benzotriazol [PDF]
Kemija u Industriji, 2007 In this paper, a review of reactions with benzotriazole as synthetic auxiliary is given. In contrast to most other azoles, benzotriazole reacts with phosgene in molar ratio 1:1 yielding carboxylic acid chloride (BtcCl, 1), which readily reacts with ...

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.

Design, synthesis and anticonvulsant activity of some new 5,7-dibromoisatin semicarbazone derivatives [PDF]
, 2013 A series of 5,7-dibromoisatin semicarbazones have been synthesized in good yield, involving aryl urea and aryl semicarbazide formation. The structures of the synthesized compounds were confirmed on the basis of their spectral data. All the compounds were

Synthesis and anticonvulsant activity of some 1-cyclohexylidine/ cycloheptylidine-4-substitued semicarbazide derivatives [PDF]
, 2020 Aryl semicarbazide derivatives are reported to possess anticonvulsant activity. On the other hand unsubstituted and small substituents (less than 3 carbon atom) containing cyclohexanones prevented both pentylenetetrazole and MES induced seizures ...

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

SusMat, Volume 5, Issue 6, December 2025.This review summarizes advances in tin (Sn)‐based perovskite solar cells, a promising lead‐free alternative. It examines the main causes of Voc and fill factor losses, including Sn2+ oxidation, undercoordinated sites, and deep‐level traps. Strategies such as molecular coordination, surface passivation, compositional tuning, interface engineering, and ...
