All‐Inorganic Cesium Zinc Halides as Ultra‐Stable Lead‐Free Perovskite Electrodes for Li‐Ion Batteries

Advanced Electronic Materials, EarlyView.
Here we explore the use of lead‐free metal halide perovskites in lithium ion batteries. Cesium zinc chloride and bromide both show reasonable discharge capacities and high stability compared to lead based perovskites. ABSTRACT Halide perovskites have recently gained attention for use as electrode materials in lithium‐ion batteries. However, lead halide

Correlation of the Auger electrons direction of movement with the internal electron conversion direction of movement [PDF]

Ядерна фізика та енергетика, 2013
On installation of coincidences of -quanta with electrons and with law energy electrons about zero area the spatial correlation of the direction emitting Auger-electrons and electron of internal conversion was investigated at the 152Eu decay.

Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

Advanced Electronic Materials, EarlyView.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...

FIELD INVESTIGATIONS OF DEFORMATIONS IN SOFT SURROUNDING ROCKS OF ROADWAY WITH ROOF-BOLTING SUPPORT BY AUGER MINING OF THIN COAL SEAMS

Rudarsko-geološko-naftni Zbornik, 2022
Coal auger mining is a promising technology used for excavating thin coal seams. The efficiency of auger mining is largely related to the stability of mine roadways in the influence zone of the coal-face.

Precise Tailoring of Charge Transport Characteristics in Zr and Hf Doped Indium Tin Oxide Thin Film Transistors

Advanced Electronic Materials, EarlyView.
Zirconium, hafnium, and mixed zirconium/hafnium doped indium tin oxide thin films are accessible by atomic layer deposition. The amorphous functional films are about 8 nm thick and show a high interdiffusion of all elements. Their transistor characteristics can be modulated depending on the amount of Zr and Hf oxide phases incorporated in these thin ...

Effect of Gate Length Relative to Recess Coverage on the Performance of Enhancement‐Mode β‐Ga2O3 MOSFETs

Advanced Electronic Materials, EarlyView.
Gate‐length engineering in recessed‐gate enhancement‐mode β‐Ga2O3 metal‐oxide‐semiconductor filed effect transistors was investigated by extending the gate to fully cover the etched recess. Complete recess coverage improves electrostatic control, reduces series resistance, shifts the threshold voltage positively, and enhances mobility, on‐resistance ...

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

Advanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

Combining ToF‐SIMS and Multivariate Analysis to Resolve Active Sites on Ni‐Based HER Catalysts

Angewandte Chemie, EarlyView.
Time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), combined with principal component analysis (PCA) and multivariate curve resolution (MCR), disentangles ultrathin mixtures of Ni, NiO, and Ni(OH)2 on model Ni electrodes. By revealing a hydroxide‐specific ion marker linked to hydrogen evolution reaction (HER) activity, the method offers a new ...

Independence of optical absorption on Auger ionization in single-walled carbon nanotubes revealed by ultrafast e–h photodoping

New Journal of Physics, 2016
Auger-ionized free-carriers in a one-dimensional semiconductor are predicted to result in a strong band-gap renormalization. Isolated single-walled carbon nanotubes (SWCNT) under high-intensity laser irradiation exhibit strong nonlinear photoluminescence
