Hydrophobicity Modulated Interfacial Water Distribution for Enhanced Kinetics of HER

Advanced Science, EarlyView.
In electrocatalysis, hydrophilic structures improve interfacial water management by forming a continuous, compact water film that facilitates proton/hydrogen transport, thereby lowering the effective adsorption free energy of H*. By contrast, hydrophobic structures enable rapid gas transport and promote the capture and local enrichment of gaseous ...

Towards Phosphorus Free Ionic Liquid Anti-Wear Lubricant Additives

Lubricants, 2016
The development of improved anti-wear additives would enable the use of lower viscosity oils that would lead to improved efficiency. Ionic liquids have the potential to be this type of new anti-wear additive.

Integrated Hydrophilic Interdigitated Network for Silicone Rubber via a Gradient Polarity Modification Strategy

Advanced Science, EarlyView.
This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Adsorption of Forever Chemical Pollutants: The Physical Chemistry of PFAS Near Surfaces

Advanced Science, EarlyView.
Current adsorption‐based remediation techniques for removing per‐ and polyfluoroalkyl substances (PFAS) from water are limited by knowledge gaps on PFAS behavior near solid surfaces. This review provides a state of the art on theoretical and experimental aspects of PFAS adsorption.

3D‐Printable Nanoporous Thermosets via Disulfide‐Based Polymerization‐Induced Microphase Separation

Angewandte Chemie, EarlyView.
α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...

Entropy Decoding the Fundamental Law of Phase Competition in Glass Formation

Advanced Science, EarlyView.
We validate the integration of intermetallic and eutectic phases as initial phases for composition design. The phase competition mechanism in glass formation is quantitatively clarified based on the melting entropy of competing phases. Glass‐forming ability is modulated by tuning phase competition via the melting entropy of initial phases.

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.
