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.

Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

European Journal of Organic Chemistry, EarlyView.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Biosensing With Nanofluidics

Exploration, EarlyView.
Nanofluidic biosensors employing in‐plane, out‐of‐plane, and free‐plane architectures transduce biomolecular information into fluidic signals through nanoscale manipulation of confined fluids, offering a quantitative and highly sensitive platform for biochemical detection. ABSTRACT Nanofluidics, the study of fluid transport confined within nanochannels

o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

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 ...
