Au9+ swift heavy ion irradiation of Zn[CS(NH2)2]3SO4 crystal: Crystalline perfection and optical properties [PDF]
, 2014 The single crystal of tris(thiourea)zinc sulphate (Zn[CS(NH2)2]3SO4) was irradiated by 150 MeV Au9+ swift heavy ions and analyzed in comparison with pure crystal for crystalline perfection and optical properties. The Fourier transform infrared and x-ray powder diffraction inferred that swift ions lead the disordering and breaking of molecular bonds in ...

Selective adsorption of Co2+ and Mn2+ by cobalt/manganese imprinted thiourea-chitosan
Fushe yanjiu yu fushe gongyi xuebao, 2022 A cobalt/manganese-imprinted adsorbent grafted with thiourea (T-Co/Mn-CTS) was synthesized through the combination of the amino groups of thiourea with imprinted chitosan (Co/Mn-CTS) by using a sol-gel method along with a reverse-phase suspension method.

A Molecular Hyper-message Passing Network with Functional Group Information [PDF]
arXiv, 2021 We proposed the molecular hyper-message passing network (MolHMPN) that predicts the properties of a molecule with prior knowledge-guided subgraph. Modeling higher-order connectivities in molecules is necessary as changes in both the pair-wise and higher-order interactions among atoms results in the change of molecular properties.

3-(2-Hydroxyethyl)-3-methyl-1-(4-methylbenzoyl)thiourea
IUCrData, 2016 The title thiourea derivative, C12H16N2O2S, has a twisted conformation with the dihedral angle between the NC(=S)N and O=CC6 planes being 35.45 (5)°. The observed conformation allows for an intramolecular N—H...O hydrogen bond.

Comments on the paper Growth and Characterization of Pure and Thiourea-Doped L-Alanine Single Crystals for NLO Devices [PDF]
arXiv, 2015 we show that the pure and thiourea-doped glycyl-L-alanine hydrochloride (GLAH and TU-GLAH) crystals claimed to have been grown by the authors of the title paper (Journal of Russian Laser Research, 34, 346-350 (2013)) are dubious crystals.

High-responsivity hybrid α-Ag2S/Si photodetector prepared by pulsed laser ablation in liquid
Beilstein Journal of Nanotechnology, 2020 We report the synthesis of α-Ag2S nanoparticles (NPs) by one-step laser ablation of a silver target in aqueous solution of thiourea (Tu, CH4N2S) mixed with cationic cetyltrimethylammonium bromide (CTAB) as surfactant. The effect of the CTAB surfactant on
