Suppression of Electric Field-Induced Segregation in Sky-Blue Perovskite Light-Emitting Electrochemical Cells.

Inexpensive perovskite light-emitting devices fabricated by a simple wet chemical approach have recently demonstrated very prospective characteristics such as narrowband emission, low turn-on bias, high brightness, and high external quantum efficiency of electroluminescence, and have presented a good alternative to well-established technology of epitaxially grown III-V semiconducting alloys. Engineering of highly efficient perovskite light-emitting devices emitting green, red, and near-infrared light has been demonstrated in numerous reports and has faced no major fundamental limitations. On the contrary, the devices emitting blue light, in particular, based on 3D mixed-halide perovskites, suffer from electric field-induced phase separation (segregation).

Electronic structure of CsPbBrCl perovskites: synthesis, experimental characterization, and DFT simulations.

All-inorganic lead halide perovskites of various compositions have emerged as a prospective family of materials for light-emitting devices and photonic applications. However, a comprehensive study of their structural and electronic properties is still missing. Moreover, thin film fabrication of these perovskites comprising heterohalide anions by wet chemistry approaches also remains challenging.

[The role of NADPH-oxidase in paracrine and autocrine regulation of platelet functional activity].

NADPH-oxidase (NOX) is a novel transmembrane enzyme that appears to have pivotal role in the control of platelet signal pathways. The NOX activity in platelets is controlled by agonist receptors activation, which, in turn are modulated by NOX. This review focuses on participation of NOX in autocrine and paracrine regulation of platelet activation, aggregation secretion, protein synthesis and cell recruitment processes during thrombus formation.
