The intersection of health inequalities and COVID‐19: Evidence from National Health Insurance Big Data in South Korea

American Journal of Community Psychology, EarlyView.
Abstract Health inequalities persist along lines of income and wealth, shaped by unequal access to healthcare, differences in health behaviors, and pre‐existing chronic conditions. The COVID‐19 pandemic further put families in Korea under health strain and worsened their health outcomes.

Observation of suppressed Auger mechanism in type-I quantum well structures with delocalized electron-hole wavefunctions

AIP Advances, 2015
We report the first observation of non-threshold Auger mechanism for a quantum well structure with Type-I band alignment. Excitation-dependent photoluminescence measurements were used to extract the Auger recombination coefficients from 77 K up to room ...

Kontrolle heterogener Katalyse mittels Unter‐Oberflächen‐Sauerstoff

Angewandte Chemie, EarlyView.
Während der CO‐Oxidation auf Rhodiumoberflächen wird die Reaktionsdynamik in der Gegenwart von Unter‐Oberflächen‐Sauerstoff (Osub) deutlich verändert. Unter‐Oberflächen‐Sauerstoff stabilisiert vorübergehend durch Oberflächenreaktionen gebildetes physisorbiertes CO2, was diesem ermöglicht, vorübergehend zu binden und mit der Oberfläche zu thermalisieren.

Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

Advanced Physics Research, EarlyView.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

Archaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Halide perovskites in wide‐spectrum photodetection

Bulletin of the Korean Chemical Society, EarlyView.
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.

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.
