Photoluminescence of Mechanochemically Manufactured Rare‐Earth Doped CsPbCl3 Microcrystals

Advanced Photonics Research, EarlyView.
The mechanochemical approach presented in this work allows for exceptional control over dopant incorporation, producing high‐quality powders suited to melt‐growth of single crystals. Through complementary structural characterization techniques (X‐ray diffraction, energy‐dispersive X‐ray spectroscopy, and X‐ray fluorescence), the nominal doping ...

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

Advanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

Nanocatalytic Neuroprotection and Neurological Recovery Post‐Traumatic Brain Injury

Advanced Science, EarlyView.
This study demonstrates that combining Ce0.7Zr0.3O2 nanozymes with nimodipine enhances neuroprotection after traumatic brain injury. The therapy reduces oxidative stress, neuronal apoptosis, and improves blood–brain barrier integrity, with nanozymes effective at low doses.

Reaction Suppression Between a High‐Ni Cathode Material (NMC622) and Li7La3Zr2O12 on Co‐Sintering for Manufacturing Bulk‐Type All‐Solid‐State Batteries: A New Method and Its Mechanism

Advanced Science, EarlyView.
A bulk‐type all‐solid‐state battery is produced by co‐sintering the proprietary NMC622 and LLZ. This proprietary NMC622 can avoid the formation of impurity phases under co‐sintering. The reduced Ni2+ fraction in NMC622 and the presence of a self‐formed Li2CO3 surface layer result in this outcome. It is possible to realize a rechargeable all‐solid‐state

Vacancy Engineered Zero‐Valent Iron Steer Hydrogen Spillover toward Per‐ and Polychlorinated Organics Rapid Complete Dechlorination

Advanced Science, EarlyView.
Zero‐valent iron with a vacancy‐rich carbon shell and lattice Cu doping in Fe0 cores generates a dechlorination mechanism combining enhanced electron transfer and modulated H* spillover, which significantly lowers the energy barrier for dechlorinating low‐chlorinated intermediates, accelerates C─Cl bond dissociation, and then delivers breakthrough ...

Electrical and Hydrogen Reduction Enhances Kinetics in Doped Zirconia and Ceria: II. Mapping Electrode Polarization and Vacancy Condensation in YSZ

, 2017
Knowing the correlation between grain boundary mobility and oxygen potential in yttria stabilized zirconia (YSZ), we have utilized the grain size as a microstructural marker to map local oxygen potential. Abrupt oxygen potential transition is established

Toward decarbonization of the titanium industry via hydrogen plasma smelting reduction

Advanced Science, EarlyView.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Catastrophic Degradation in Solid Oxide Fuel Cells Caused by Air Supply Interruption in Real‐World Operations: Fundamental Mechanisms and Mitigation Strategies

Advanced Science, EarlyView.
Interrupting the air supply during the operation of solid oxide fuel cells leads to irreversible chemical degradation of the cathode materials, primarily driven by strontium at the A‐site of perovskite structures. Alternative strontium‐free materials effectively address this issue, ensuring high performance and reliable operation during operational ...
