In Situ Reconstructed Crystalline–Amorphous CuNi Nanotubes Unifying Activity and Stability for Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Controlled electrochemical reconstruction creates a crystalline–amorphous CuNi nanotube that unifies catalytic activity and durability for alkaline oxygen evolution. The conductive metallic core and active amorphous oxide shell work synergistically to deliver low overpotential and exceptional stability exceeding 1000 h, offering a new strategy for ...

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

open access: yesCase 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 ...

Adaptive and Highly Efficient Thermoregulation Based on Multi‐Dimensional Janus Film

open access: yesAdvanced Science, EarlyView.
A switchable TiO2/MXene/PDMS Janus membrane enables dual‐mode radiative cooling and solar heating, achieving sub‐ambient cooling of 17.89°C and above‐ambient heating of 13.82°C. Adaptive temperature regulation was demonstrated with a low power integrated autonomous smart curtain system, providing a sustainable and energy‐efficient alternative for ...

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

open access: yesAngewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Mn2+ Ion‐Mediated Zn Dendrite Suppression and Reversible Stripping in Aqueous Zn‐Ion Batteries as Revealed by In Situ Liquid‐Cell TEM

open access: yesAdvanced Science, EarlyView.
In situ EC‐LPTEM directly visualizes how Mn2+ ions regulate Zn electrodeposition and dissolution in aqueous electrolytes. Mn2+ suppresses heterogeneous growth and dendritic elongation while promoting more reversible stripping. These findings reveal additive‐regulated interfacial processes during Zn deposition and dissolution and provide guidance for ...

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

open access: yesNatural 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.

Balancing Bulk Solution Chemistry and Cation Solvation for Stable Aqueous Aluminum Batteries

open access: yesAdvanced Science, EarlyView.
A dual‐scale electrolyte design balances bulk solution chemistry and cation solvation in aqueous aluminum batteries. Regulation of the bulk solution preserves high ionic conductivity and electrochemical stability, while modulation of the Al3+ solvation environment lowers desolvation penalties and suppresses hydrogen evolution. This balanced electrolyte

Adaptive Cu Reconstruction in Heterostructure Drives High‐Rate Nitrate‐to‐Ammonia Conversion

open access: yesAdvanced Science, EarlyView.
An adaptively reconstructed Cu/CoOX heterojunction, featuring a surface‐localized, hydroxyl‐rich oxidized Cu species, forms in situ from a CuO/CoOX (Co1Cu9OX) pre‐catalyst during electrochemical nitrate reduction. The self‐adaptive reconstruction and the incorporation of heterostructure regulate nitrogen‐containing intermediate adsorption and *H supply,
