General description

The structure of copper(I) chloride is similar to zinc-blende crystal at room temperature, at 407 °C the structure is wurtzite and at still higher temperature it forms copper(I) chloride vapor as determined by mass spectroscopy.

Application

Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.
CuCl may be used as an initiator for hydrostannation of α,β-unsaturated ketones and other similar radical reactions.

The ternary chalcogenide Cu3VSe4 (CVSe) with sulvanite structure has been theoretically predicted to be a promising candidate for photovoltaic applications due to its suitable bandgap for solar absorption and the relatively earth-abundant elements in its composition. To realize the absorber...

Here we describe the development of versatile antifouling polyethersulfone (PES) filtration membranes modified via surface grafting of zwitterionic polymers from a reactive amphiphilic copolymer additive. Amphiphilic polyethersulfone-block-poly(2-hydroxyethyl methacrylate) (PES-b-PHEMA) was beforehand designed and used as the blending additive of PES...

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
