Metal-catalyzed direct arylation of 1,2-azoles
(Academic Press, 2019)
Over the last 20 years, there has been significant progress in the direct CH (het)arylation chemistry of a wide variety of (het)arenes. Herein, the application of direct CH arylation on the 1,2-azoles: pyrazoles, isothiazoles, ...
Agricultural biomass/waste as adsorbents for toxic metal decontamination of aqueous solutions
(2019)
Toxic metals can be present in the environment, causing negative effects on the ecosystem and human health. Although several technologies have been used for decontamination purposes, biosorption is an environmentally ...
Selective separation and determination of uranium in calcite and gypsum after EDTA-mediated sample dissolution and cation-exchange
(2019)
The present paper describes a relatively simple, effective, very selective and economic method for the determination of uranium in calcite and (phospho)gypsum samples. The analysis is performed by alpha-spectroscopy after ...
U(VI) adsorption by biochar fiber–MnO2 composites
(2019)
The removal of U(VI) by biochar fibers from aqueous solutions has been investigated prior and after MnO2 surface-deposition. The removal efficiency has been studied as a function of pH, U(VI) concentration, ionic strength, ...
Recovery of uranium from phosphate rock with EDTA-mediated dissolution and cation exchange
(2019)
The present study describes an alternative, environmentally friendly, simple, and material- and cost-effective process for the selective separation and recovery of uranium from phosphate rocks by cation-exchange using an ...
Water-stable 2-D Zr MOFs with exceptional UO22+ sorption capability
(Royal Society of Chemistry, 2019-12-02)
Two new 8-connected 2-D MOFs, UCY-13 and UCY-14, based on Zr6 secondary building units (SBUs) and angular dicarboxylate ligands are reported. UCY-13 and UCY-14 display remarkable stability in various types of aqueous media, ...
Antiproliferative activity and apoptosis induction, of organo-antimony(III)–copper(I) conjugates, against human breast cancer cells
(Springer, 2019)
Three known organo-antimony(III)–copper(I), mixed-metal small bioactive molecules (SBAMs) of formula [Cu(tpSb)3Cl] (1), [Cu2(tpSb)4Br2] (2) and [Cu2(tpSb)4I2] (3) (tpSb = triphenylstibine) were used for the clarification ...
