On Oxalyl Halide Isothiocyanates Part I: Syntheses and Isomerism
European Journal of Inorganic Chemistry, EarlyView.Oxalyl halide isothiocyanates can be prepared from oxalyl halide with one equivalent of NH4SCN in liquid SO2. While oxalyl bromide isothiocyanate can be isolated as a liquid, the respective chloride compound readily undergoes isomerization under formation of a thiazole ring, which is obtained as a solid.

Cation Distribution in Li2CaSiO4:Gd, Pr, Na Uncovered Through Anomalous Diffraction
European Journal of Inorganic Chemistry, EarlyView.Li2CaSiO4 co‐doped with Gd3+ and Pr3+ shows strong blue‐to‐UV‐B up‐conversion. Herein, we explore the doping element distribution in order to discern the reason for the strongly supportive co‐doping effect using high‐resolution Rietveld refinement and multiple‐edge anomalous dispersion measurements.

FlexMat, EarlyView.By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy
iNew Medicine, EarlyView.ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Irrigation and Drainage, EarlyView.ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Journal of the Chinese Chemical Society, EarlyView.The photophysical performance of gold‐doped copper‐rich nanoclusters can be tuned by surface functionalization. Subtle ligand modification enhances intermolecular interactions, thereby reducing nonradiative decay and markedly improving photoluminescence. Comparative photographs and quantum yield values (Φ = 55% vs.

Journal of the Chinese Chemical Society, EarlyView.While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?
