Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

The synergistic effect of silica fume and γ-C2S on the carbonation resistance of supersulfated cement

Developments in the Built Environment
The poor carbonation resistance of supersulfated cement (SSC) is one of the key bottlenecks limiting its engineering applications. This paper investigates the synergistic effect of γ-C2S and silica fume (SF) on improving the carbonation resistance of SSC.

Proposal for classification of concrete quality based on accelerated carbonation tests

Case Studies in Construction Materials, 2023
Reinforcement corrosion is a problem affecting the durability of most concrete structures. When concrete is employed without proper care, it may function inadequately as a barrier, allowing aggressive ions or acidic substances in the atmosphere to attack

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Verification of Interaction Between Cl⁻ Erosion and Carbonation in Marine Concrete

Journal of Marine Science and Engineering
Marine concrete frequently experiences performance degradation due to the combined effects of chloride ion (Cl−) erosion and carbonation. While many studies have examined the separate effects of Cl− erosion and carbonation, their combined impact on ...

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.
