Photochemical Isomerizations of Thiosemicarbazide, a Matrix Isolation Study
Two thione conformers of monomeric thiosemicarbazide were trapped from the gas phase into a low-temperature Ar matrix. A phototransformation converting the less stable form of the compound into the most stable conformer was induced by irradiation with ...

ABSTRACT This study aimed to evaluate the toxicological effects of occupational exposure to factory‐derived particulate matter (PM2.5) on human skin, emphasizing its role as a potential target organ of environmental toxicants. An epidemiological survey comparing factory and nonfactory workers was conducted by assessing their skin elasticity and color ...

Growth and characterization of thiosemicarbazide hydrochloride: A semiorganic NLO material
Thiosemicarbazide hydrochloride (TSCHCL) was synthesized by mixing thiosemicarbazide and hydrochloride in 1:1 molar ratio in double distilled water. Single crystals of TSCHCL were grown by slow evaporation at room temperature and were characterized by ...

1-(Biphenyl-4-ylmethylidene)thiosemicarbazide monohydrate [PDF]
In the title compound, C14H13N3S·H2O, the thiosemicarbazide group is nearly planar, with a maximum deviation of 0.072 (2) Å from the ideal least-squares plane, and shows an E conformation. In the crystal packing, the

Urea provides an important nitrogen source for microbial populations in an ultraoligotrophic sea
Urea is an organic nitrogen (N) compound directly utilized by both heterotrophic prokaryotes and some photoautotrophs. Reports of either ambient urea concentrations or urea uptake rates from the ultraoligotrophic eastern Mediterranean Sea are lacking. We investigated urea distribution and uptake in the upper water column in the Levantine basin during ...
