Promethium-148 has been produced by two methods: (1) (n, γ) reaction on Pm-147, (2) (p, n) reaction on enriched Nd-148. In both instances two activities were observed: 5.4d Pm-148 and 41.8d Pm-148. The decay of these isomers has been followed by use of ion-chambers, betacounters, and gamma scin...

Currently, forty-one cesium, thirty-five lanthanum, thirty-two praseodymium, and thirty-one promethium isotopes have been observed and the discovery of these isotopes is described here. For each isotope a brief synopsis of the first refereed publication, including the production and identificati...

In this paper, we describe the 147Pm production yields and level of impurities from several targets that consisted of milligram quantities of highly enriched 146Nd oxide irradiated at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory for durations ranging from 24 to 180 h. A ...

S-nitrosylation, regulated by S-nitrosoglutathione reductase (GSNOR), is considered as an important route for nitric oxide (NO)-modulated stress tolerance in plants. However, genetic evidence for the GSNOR-mediated integrated regulation of S-nitrosylation and plant stress response remains elusiv...

This work aims to describe the wine fermentation characteristics of 23 natural S. cerevisiae × S. kudriavzevii hybrid yeasts related to fermentative environments isolated from different regions and their significance for the aroma spectra of the produced wines. Fermentations were performed at 1...

The identification of S-nitrosated substrates and their target cysteine residues is a crucial step to understand the signaling functions of nitric oxide (NO) inside the cells. Here, we show that the key nitrogen metabolic enzyme glutamine synthetase (GS) is a S-nitrosation target in Medicago tru...

The N-methyl-d-aspartate receptor (NMDAR) antagonist (R,S)-ketamine produces rapid and sustained antidepressant effects in treatment-resistant patients with depression although intranasal use of (R,S)-ketamine in ketamine abusers is popular. In March 5, 2019, nasal spray of (S)-ketamine for trea...

Cu2ZnSn(S,Se)4 (CZTSSe) absorber layers with various S/(S + Se) ratios at the surface and in the bulk were synthesized to investigate the effect of the S/(S + Se) ratios on the formation of secondary phases in the CZTSSe absorber layer. The higher density ZnS and Cu2SnSe3 (CTSe) secondary phases...

A novel reaction-based O-acyl pyrene amidoxime derivative was easily synthesized from pyrene-1-carbaldehyde in three step and fully characterized. The sensing ability of the receptor towards various anions were investigated. The receptor exhibited distinct fluorescent behavior by a 45-fold incre...

Balanced charge transport is crucial to realize efficient organic light-emitting diodes. In this work, pyrene derivatives featuring variable number of cyano-functionalized carbazoles are synthesized and characterized by photophysical, electrochemical, thermal and electroluminescence studies. The...

I.r. spectroscopy was used to determine the enthalpy of hydrogen bond complex formation of 1-cyclohexyluracil with acetylglycine N-methylamide, in chloroform solution. Enthalpy of association is found to be −5.4 Kcal/mole for the dimer of acetylglycine N-methylamide and −4.7 Kcal/mole for the mi...

Optically active N-formyl-N-hydroxy-α-phenylalanine methylamide (1) and N-formyl-N-hydroxy-β-phenylalanine methylamide (2) were evaluated as inhibitors for thermolysin (TLN) to find that while the d-form is more potent than its enantiomer in the case of the hydroxamate of α-Phe-NHMe, in the i...

Readily available air- and moisture-stable dimeric chloro-bridged CN-, CS- and CP-cyclopalladated complexes with the (sp2)C–Pd bond react with 4.5 equiv. of KPPh2 in THF to give the corresponding P,N-, P,S- and P,P-bidentate ligands in 35–63% yield. The phosphination method is applicable to fi...

The Knudsen mass-loss effusion technique was used to measure the vapour pressures at different temperatures of the following halobenzoic acids: 2-chlorobenzoic acid, between T = (320.16 and 339.15) K, 3-chlorobenzoic acid, between T = (320.13 and 340.13) K, 4-chlorobenzoic acid, between T = (333...

In this study, the molecular conformation, vibrational and electronic transition analysis of 2,3-difluorobenzoic acid and 2,4-difluorobenzoic acid (C7H4F2O2) were presented using experimental techniques (FT-IR, FT-Raman and UV) and quantum chemical calculations. FT-IR and FT-Raman spectra in sol...

Myocardial fuel selection is a key feature of the health and function of the heart, with clear links between myocardial function and fuel selection and important impacts of fuel selection on ischemia tolerance. Radiopharmaceuticals provide uniquely valuable tools for in vivo, non-invasive assess...

Absolute vapor pressures and molar sublimation enthalpies of 2-, 3-, and 4-monohalogenobenzoic acids (halogen = fluorine and iodine) were derived from transpiration measurements. Molar enthalpies of fusion were measured by DSC. Thermochemical data available in the literature were collected, eval...
