Oxygen‐Regulated GaN‐Based Sensors Fabricated by MOCVD for Switchable Gas Detection: Exhaled Gas Smart Platform for Non‐Invasive Disease Detection

Advanced Science, EarlyView.
This work presents highly consistent GaN‐based thin‐film gas sensors prepared by MOCVD for non‐invasive breath analysis. The sensors exhibit tunable selectivity from oxidizing to reducing gases by incorporating In composition, ultra‐low detection limits and humidity resistance.

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.

Cu─O─Al Interfacial Engineering on Cu Nanowires for Durable CO2 Electroreduction Into Multi‐Carbon Products

Advanced Science, EarlyView.
A Cu nanowire/AlOx core‐shell catalyst is reported for CO2 electroreduction. Acting as a Lewis acid, the AlOx shell not only stabilizes Cu+ species at the Cu─O─Al interface but also creates an alkaline local microenvironment via *OH adsorption. This dual functionality stabilizes the catalyst structure while promoting the C─C coupling process, resulting

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.

Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

Advanced Science, EarlyView.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

In Situ Construction of Cu1+/Cu0 and Cu2+/Cu0 Pairs of Cu‐Based Catalysts for Electrocatalytic Nitrate Reduction

Advanced Science, EarlyView.
CuO and CuPO (Cu2P2O7 and Cu3(PO4)2) as precursors are in suit construction two distinct copper‐based active sites during the NO3RR reaction: Cu1+/Cu0 (derived from CuO) and Cu2+/Cu0 (derived from CuPO). Cu1+/Cu0 is the key to achieving high activity and high selectivity.

Photocatalytic Asymmetric C‐C Coupling for CO2 Reduction on Cu‐Zn Bimetallic Catalysts with Dipole‐Limiting Effects

Advanced Science, EarlyView.
Asymmetric Cu–Zn dual sites on EDTA‐grafted Ti‐MOF amplify the dipole‐limiting domain field (DLDF), facilitating C–C coupling. This strategy yields an exceptional C2H4 production rate of 308.72 µmol g−1 h−1 with 98.4% electron selectivity in photocatalytic CO2 reduction, highlighting the potential of asymmetric site engineering and local field ...

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...
