Open AccessAchieving volatile potassium promoted ammonia synthesis via mechanochemistry
Potassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) is better in theory. The reason K2O is used is because metallic K, which volatilizes around 400 °C, sep...

Ultralow-dielectric-constant amorphous boron nitride
Decrease in processing speed due to increased resistance and capacitance delay is a major obstacle for the down-scaling of electronics1–3. Minimizing the dimensions of interconnects (metal wires that connect diff...

Open AccessObservation of Restored Topological Surface States in Magnetically Doped Topological Insulator
The introduction of ferromagnetic order in topological insulators in general breaks the time-reversal symmetry and a gap is opened in topological surface bands. Various studies have focused on gap-opened magne...

Open AccessInvestigation of Thermally Induced Degradation in CH3NH3PbI3 Perovskite Solar Cells using In-situ Synchrotron Radiation Analysis
In this study, we employ a combination of various in-situ surface analysis techniques to investigate the thermally induced degradation processes in MAPbI3 perovskite solar cells (PeSCs) as a function of temperatu...

Open AccessCoulomb nanoradiator-mediated, site-specific thrombolytic proton treatment with a traversing pristine Bragg peak
Traversing proton beam-irradiated, mid/high-Z nanoparticles produce site-specific enhancement of X-ray photon-electron emission via the Coulomb nanoradiator (CNR) effect, resulting in a nano- to micro-scale th...

Direct visualization of a cycloaddition reaction on frozen asymmetric Si dimers at room temperature
We firstly report an experimental visualization of a cycloaddition reaction on RT frozen asymmetric Si dimers. The frozen Si dimers with a local c(4 × 2) order were prepared by pinning flip-flop** Si dimers ...

Rotation curve of galaxies by the force induced by mass of moving particles
Many attempts have been made to explain the flat rotation curve of spiral galaxies regardless of distance from the center, in disagreement with the Newtonian prediction that this speed should diminish as the i...

Investigation of Amorphous InGaZnO Based TFT Interface Properties with Synchrotron Radiation Analysis
We investigated the amorphous indium gallium zinc oxide (IGZO) based TFT interface properties using synchrotron radiation analysis. Near edge x-ray absorption fine structure shows the presence of N2 molecules bet...
