Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes

Chemistry – A European Journal, EarlyView.
A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

Photometric Diagnostic of the Sheath Dynamics and Electron Density Trends in Single and Dual Frequency CCRF Argon Plasmas

Contributions to Plasma Physics, EarlyView.
ABSTRACT A methodological study is presented on a noninvasive photometric diagnostic for determining trends in electron density and sheath dynamics in single (1f) and a dual (2f) radio frequency capacitively coupled (CCRF) argon plasmas. The 1f discharges are operated at 13.56 and 27.12 MHz, respectively, while the 2f discharge is driven by both ...

The $n {-} \bar n$ oscillations in neutron fluxes running from Sun to Earth

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The process of $n {-} \bar n$ oscillations in the solar cosmic-rays is considered. It is shown that it has high intensity with respect to the analogic processes on the Earth $(I_{c{-}r}/I_{Earth} \propto 10^8)$, because magnetic field strongly suppresses
