Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

Advanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning

Formation‐Stage Interfacial Regulation of δ‐MnO2 Enables Stable and Reversible Aqueous Zn‐Ion Storage

Advanced Science, EarlyView.
Precursor‐embedded Fe regulates the nucleation and growth of δ‐MnO2, enabling a more accessible and stable Zn‐storage interface with accelerated kinetics and suppressed Mn dissolution, while preserving the intrinsic Mn redox chemistry. ABSTRACT Layered δ‐MnO2 is a promising cathode for aqueous zinc‐ion batteries, yet its practical application remains ...

Pure Laparoscopic Left Hemihepatectomy for Hepatic Peribiliary Cysts with Biliary Intraepithelial Neoplasia

Case Reports in Surgery, 2016
Introduction. Hepatic peribiliary cysts (HPCs) usually originate due to the cystic dilatation of the intrahepatic extramural peribiliary glands. We describe our rare experience of pure laparoscopic left hemihepatectomy (PLLH) in a patient with HPCs ...

DTX3 Suppresses the NPM3–RUVBL1 Axis to Inhibit Homologous Recombination Repair and Abrogate Tumor Radioresistance

Advanced Science, EarlyView.
Deltex 3 (DTX3) catalyzes K27‐linked ubiquitination of nucleophosmin 3 to disrupt homologous recombination repair and reverse tumor radioresistance. Low DTX3 predicts poor survival and radiotherapy recurrence, serving as a radiosensitizing therapeutic target.

A Novel One-step Synthesis of Quinoline-2(1)-thiones and Selones by Treating 3-Aryl-3-(2-aminophenyl)-1-propyn-3-ols with a Base and Elemental Sulfur or Selenium

Natural Product Communications, 2015
A one-step conversion of 3-aryl-3-(2-aminophenyl)-1-propyn-3-ols into quinoline-2(1 H )-thiones and quinoline-2(1 H )-selones was achieved only by treating the substrates with n -butyllithium and either elemental sulfur or selenium, respectively.

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

Advanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Mechanistic Origin of Capacity Limitation in Sidorenkite‐Type Na3‐xFe(PO4)(CO3) Carbonophosphate Cathodes for Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
The potential–capacity profile reveals a one‐electron limitation in sidorenkite Na3−xFe(PO4)(CO3). Structural analysis shows that Fe4+ formation induces lattice strain and suppresses electronic conductivity, blocking further Na extraction. These findings establish key design rules: preserve crystallinity, avoid Jahn–Teller–active d4 configurations, and
