Luminescent behavior of the K2SiF6:Mn4+ red phosphor at high fluxes and at the microscopic level [PDF]

, 2016
Phosphor-converted white light-emitting diodes (LEDs) are becoming increasingly popular for general lighting. The non-rare-earth phosphorK(2)SiF(6): Mn4+, showing promising saturated red d-d-line emission, was investigated.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Defect Analysis of the β– to γ–Ga2O3 Phase Transition

Advanced Functional Materials, EarlyView.
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

NEW ADDUCTS BETWEEN N-[FERROCENYLMETHYL] DIMETHYLAMMONIUM AND HALOMETALLATES: SYNTHESIS AND INFRARED STUDY

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2016
Eight new adducts between N-[ferrocenylmethyl]dimethylammonium and halometallates were obtained in ethanolic media. From an infrared study, the suggested structures are monomeric or dimeric for tin compounds which contain [SnCl4(OH)2]2-, [(SnCl5)]- and
