X-ray single crystal analysis of CBEDEA shows that the molecule crystallized in the triclinic crystal system, ...

The condensation reaction of biphenyl-4-carbonyl isothiocyanate/4-chlorobenzoyl isothiocyanate with diphenylamine yielded two new compounds; N-diphenyl-N'-(biphenyl-4-carbonyl) thiocarbamide (1) and N, N-diphenyl-N'-(4-chlorobenzoyl) thiocarbamide (2). Structure of the compounds were d...

This contribution describes the facile preparation of functional yolk–shell nanoparticles (YSNs) made up of different compositions confined within a hollow porous carbon shell ([email protected], M = multiple Cu, NiO nanoparticles or ZnO nanowires). These new yolk–shell hybrid materials have b...

Berberine hydrochloride (Brb) is a well-known herbal drug that holds a great promise in the recent years thanks to its various pharmacological actions. Currently, Brb is extensively researched as a natural surrogate with evidenced potentiality against numerous types of skin diseases including sk...

The efficient separation of pentlandite from serpentine remains a challenging issue in the processing of nickel sulfide ores. In this study, selective magnetic coating-magnetic separation was employed to separate the pentlandite from serpentine with adding NaOL as a coagulant, which is different...

The effect of calcium ions on the adsorption of sodium oleate on the mineral surfaces and flotation separation of cassiterite from quartz were studied in this work through micro-flotation tests, zeta potential measurements, solution chemistry calculation, surface adsorption experiments, and X-ra...

The effects of Pb(II) ions on the flotation of hemimorphite was investigated by micro-flotation tests, zeta-potential measurements, solution chemistry and Fourier transform infrared spectroscopy. The micro-flotation results indicated that the Pb(II) effectively improved the flotation of hemimorp...

The flotation of pyrochlore using two common oxide collectors, octyl hydroxamic acid (OHA) and sodium oleate (NaOl), was studied by microflotation tests on high purity pyrochlore sample and batch flotation tests on a pyrochlore ore sample.
