Covariance mapping of two-photon double core hole states in C2H2 and C2H6 produced by an x-ray free electron laser

New Journal of Physics, 2015
Few-photon ionization and relaxation processes in acetylene (C _2 H _2 ) and ethane (C _2 H _6 ) were investigated at the linac coherent light source x-ray free electron laser (FEL) at SLAC, Stanford using a highly efficient multi-particle correlation ...

Water‐Activated Proton Transfer Mediated by Subnanoscale CeO2‐Cu2O Interfaces for Near‐Unity CH4 Selectivity in Photothermal CO2 Reduction

EcoEnergy, EarlyView.
Subnanoscale CeO2‐Cu2O particles can efficiently catalyze the hydrogenation of the key intermediate *CO to CH4 at an impressive rate of 2818 μmol g−1 h−1 in photothermal CO2 reduction. ABSTRACT Water‐mediated photothermal CO2 reduction to CH4 is promising for renewable energy storage and carbon neutrality, but its selectivity and efficiency are limited

Studies of Solids and Surfaces by Auger Electron Spectroscopy

, 1986
Although the applications of Auger electron spectroscopy in surface analysis have by far outweighed its use as a tool to investigate electron states of solids and surfaces, there are a variety of situations where Auger spectroscopy provides unique ...

Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

EcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Noble Metal Auger Spectroscopy As A Probe Of Electronic Structure: Mapping Fermi Energies In Trimetallic Alloys

, 2015
XPS binding energy shifts in alloys are sensitive to valence occupation changes. Since binding energies are defined relative to the Fermi energy, exploitation of this property of the shifts has been hampered by ignorance of relative Fermi energies ...

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...
