Orthogonal Design of Competing Deprotonation Process in Cation‐Mediated Ni(OH)2 for Achieving Industrial Level Biomass Electrooxidation

Advanced Science, EarlyView.
A Cu‐mediated Ni(OH)2 catalyst with orthogonal activity by precise valence engineering simultaneously accelerates rate‐determining aldehyde C─H activation in HMF oxidation and impedes O─H deprotonation in competing OER. This multi‐functional synergistic catalysis enables FDCA production at industrial‐level current densities without sacrificing FEFDCA ...

Carboxyphenolate Coordination Frameworks for High‐Voltage Calcium Storage

Advanced Science, EarlyView.
A hexaanionic carboxyphenolate coordination framework, Ca2‐M‐THBPD (M = Mg, Ca, Ba), exhibits ligand‐centered enolate‐quinonoid redox activity enabling tunable, high‐voltage Ca2+ storage (3.5 V vs Ca2+/Ca) modulated by spectator cations. The amorphous structure accommodates reversible divalent‐ion insertion, contributing to enhanced cycling stability ...

Determination of Sulfur in High-sulfur Bauxite by Alkali Fusion-Inductively Coupled Plasma-Optical Emission Spectrometry

Yankuang ceshi, 2017
When Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) is used to analyze the sulfur content of high-sulfur (S≤8%) bauxite, commonly used acid dissolving and alkali fusion methods cannot oxidize sulfur completely, leading to a false ...

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

Advanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Determination of As, Sb and Bi in Soil and Stream Sediment by a Self-developed Hydride Generation System Coupled with Inductively Coupled Plasma-Optical Emission Spectrometry

Yankuang ceshi, 2015
Hydride Generation (HG) combined with Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) has excellent analytical sensitivity. However, the instable chemical reactions of HG may cause unsatisfactory analytical precision.

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.
