Bio‐Inspired Carbon Spheres Enable Active Sites Multiscale‐Anchoring and Pre‐Reduction

Carbon Energy, EarlyView.
Combining the wet‐spinning technique with a “bionic design” concept, a bio‐inspired carbon sphere support with internal finger‐shaped pores and external craquelure structures is designed and constructed, and the corresponding carbon sphere reactor is fabricated through the multiscale anchoring and the pre‐reduced promoting, and verified for application

The M5 photoelectron line of Ag metal measured in coincidence with the M5–N45N45 Auger-electron spectral line

, 2005
The M5 (3d5/2) photoelectron line of Ag metal was measured in coincidence with the M5–N45N45 (1G or 3F) Auger-electron line by Auger-photoelectron coincidence spectroscopy (APECS). The M5 photoelectron line of Ag metal measured in coincidence with either

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Quantifying Efficiency Roll‐Off Factors in Quantum‐Dot Light‐Emitting Diodes

Advanced Science
The application of quantum‐dot light‐emitting diodes (QLEDs) is hindered by efficiency roll‐off at high current densities. Factors contributing to this roll‐off include Auger recombination, electric field‐induced quenching, Joule heating, and electron ...

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 ...

Electron energy-loss spectroscopy: DFT modelling and application to experiment [PDF]

, 2010
The all-electron density functional theory (DFT) code Wien2k has an established track record of modelling energy-loss near-edge structure (ELNES). The pseudopotential DFT code CASTEP can reproduce results found using Wien2k.

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1

EcoEnergy, EarlyView.
A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...
