Hepatocellular carcinoma (HCC) is the most common primary liver tumor and one of the fifth most common tumors worldwide. In this article we report the results of in vivo studies of potential anticancer agent "[188Re] rhenium-ImDendrim" derived from [188Re]rhenium-nitro-imidazole-methyl -1,2,3-triazol-methyl-di-(2-pycolyl)amine as radioactive ligand loaded 5th generation poly-L-lysine denrimer (...

The high-valent oxo-molybdenum(VI) and -rhenium(VII) and -(V) derivatives MoO2Cl2, ReCH3O3 (MTO) and ReIO2(PPh3)2 catalyze the selective hydrogenation of alkynes to alkenes at 80 degrees C under 40 atm of pressure. The reduction of sulfoxides to sulfides has also been performed by oxo-rhenium and -molybdenum complexes using hydrogen as a reducing agent. Activation of hydrogen by MoO2Cl2 and MoO...

Gel-permeation chromatography (GPC) has been used to analyze transition-metal-based squares, triangles, and related supramolecular complexes. Using rhenium-containing molecular squares of different sizes, a linear calibration curve has been established, which was used for confirming the relative sizes of other assemblies. GPC can also discriminate cyclic trimers and tetramers of a dirhodium bui...

Garg* Correction for ‘Synthetic chemistry fuels interdisciplinary approaches to the production of artemisinin’ by Michael A. Corsello et al., Nat. Prod. Rep., 2015, DOI: 10.1039/c4np00113c. Due to a production error, in section 6 in the sentence that reads “First, ...

a r t i c l e i n f o a b s t r a c t Keywords: Reverse Monte Carlo EXAFS Wavelet analysis Germanium Rhenium trioxide In this work we present the Reverse Monte Carlo (RMC) modeling scheme, designed to probe the local structural and thermal disorder in crystalline materials by fitting the wavelet transform (WT) of the EXAFS signal. Application of the method to the analysis of the Ge K-edge and R...

NaRe$_2$(PO$_4$)$_3$ phosphate-based ceramic with the structure of kosnarite mineral was obtained by spark plasma sintering. Rhenium (Re) served as a chemical and structural analog technetium. The relative density 85%. mechanism Re static leaching from at room temperature investigated. rate rhenium $1.3\times10^{-5}$ g/(cm$^2$*day).

A thermal stress range analysis of tungsten-rhenium thin film thermocouples based on ceramic substrates is presented to analyze the falling off and breakage problems caused by the mismatch of the thermal stresses in thin film thermocouples (TFTCs) and substrate, and nano-indentation experiments are done to measure and calculate the film stress to compare with the simulation results. Optimal des...

Selective dissolution of a tungsten (85 wt.%)–rhenium (15 wt.%) alloy with rhenium in hydrochloric acid at the temperature 298 K and anodic polarization modes was carried out to develop porous catalytic substrate recycle rare metals. The parameters effective selective tungsten–rhenium alloy, including differences applied potentials electrolyte composition, were found. It established that sample...

Rhenium-catalyzed stereoselective transposition of allylic alcohols is reported.

Four rhenium(I) chromophores attached to a dirhodium(n) core form a new hexametallic light-harvesting assembly as characterised by X-ray crystallography, UV-vis spectroscopy and electrochemistry.
