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.


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.

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...

Plant mitochondria are highly responsive organelles that vary their metabolism in response to a wide range of chemical and environmental conditions. Quantitative proteomics studies have begun to allow the analysis of these large-scale protein changes in mitochondria. However studies of...


Nanostructured Materials Through Ultrasonic Spray Pyrolysis

Advances in materials have often been led by the development of new synthetic methods that provide control over size, morphology and structure. The preparation of materials in a scalable and continuous manner is critical when development moves beyond lab-scale quantities.

Lanthanide Ions as Photon Managers for Solar Cells

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).
