a series of transition metal complexes with two thiosemicarbazide schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (abtsc) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (tcts) were synthesized with co(ii), ni(ii), zn(ii), cd(ii) and ag(i) salts (chloride and acetate). these complexes were characterized by different methods including proton nuclear magnetic resonance (1hnmr), ...

Transient precursor states are often experimentally observed for molecules adsorbing on surfaces. However, such precursor states are typically rather short-lived, quickly yielding to more stable adsorption configurations. Here we employ first-principles calculations to systematically explore the interaction mechanism for benzene derivatives on metal surfaces, enabling us to selectively tune the...

hie-124 is a new member of ultra-short acting hypnotics’ drug family. in this research, the synthesis ofanalogues of hie-124 drug in the heterocyclic thiazole ring replaced to thiadiazole, will be presented.thiadiazolodiazepines during a two-step reaction starting from the amino thiadiazole resultedfrom-various derivatives of benzoic acid and thiosemicarbazide were synthesized. in the first ste...

An< accurate, stable and very fast corner finder (for feature based vision) has been developed', based on a novel definition of corners, using:no image derivatives. This note describes the algorithm and the results obtained from its use.
