In this study, surface chemistry and flotation properties of the gold-bearing galena pyrite minerals Menderes region, Izmir, Turkey were investigated with use xanthate-thiocarbamate-monothiophosphate collectors. context, micro-flotation experiments, zeta potential, bubble-particle attachment time measurements conducted in presence Thiophosphate (Aero S-8045), Xanthate (SIBX), Thiocarbamate floa...

Vinylidene fluoride (VDF) emulsion polymerization is conducted in the presence of xanthate-end functionalized poly(ethylene glycol)s leading to stable PVDF latexes.

In the mol-ecule of the title compound, [Sb(C(7)H(11)OS(2))(3)], the anti-mony(III) is coordinated by the S atoms of three O-alkyl xanthate groups acting as monodentate ligands, forming a distorted trigonal-pyramidal coordination.

This paper attempts to analyze the propagation characteristics of radio signal inside a partially open drain environment using an empirical approach. The proposed research topic concerns a unique situation in several Asian countries because the drainage systems in these countries differ notably from those in the US and Europe in that the former are partially open on the top while the latter are...

A reference counting garbage collector cannot reclaim unreachable cyclic structures of objects. Therefore, reference counting collectors either use a backup tracing collector seldom, or employ a cycle collector to reclaim cyclic structures. Recently, the first on-the-fly cycle collector, that may run concurrently with program threads, was presented by Bacon and Rajan [3]. This demonstrated the ...

the shape of a solar collector is an important factor in solar-to-thermal energy conversion. conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. the present study is an experimentally investigated of the performance of the solar coni...

Convergent routes to various classes of lactams exploiting the unique radical chemistry xanthates are described. Emphasis is placed on reactions leading by direct cyclization, intermolecular additions alkenes followed ring closure, and furnishing amino esters acids precursors that can be converted into ionic condensations. The possibility modifying existing lactam structures briefly discussed. ...

1-[(Ethoxycarbonothioyl)sulfanyl]cyclobutyl acetate (xanthate 7) was found to add electronically unbiased alkenes and certain heteroarenes. In the latter case, this corresponds a variant of Minisci reaction allows late-stage modification biologically active substances. Saponification furnishes corresponding cyclobutanols, which, in case nicotine adduct, can be converted into fluorocyclobutanes ...
