Organo-montimorillonites containing a reactive thiophene group for polythiophenes nanocomposites

Cerâmica
A sodium montmorillonite clay (Na+MMT) was modified with different contents of a reactive salt derived from thiophene (trimethyl-(2-thiophen-3-yl-ethyl)-ammonium bromide) (TMETA). The thiophene salt in the organoclay (xtioMMT) was oxidatively polymerized

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.

CO2‐to‐CO Electrolysis in Pure Water at Ampere‐Level Current Density and 1000 h Stability via a Rapid‐Transport Fixed‐Charge Interface

Advanced Science, EarlyView.
CO2 reduction in pure water is enabled by a rapid‐transport fixed‐charge interface that couples nanochannels with a cationic microenvironment. This design eliminates the mass transport plateau, stabilizes key reaction intermediates, and suppresses the hydrogen evolution reaction, ultimately achieving ampere‐level current densities and stable operation ...

Engineering Trace‐Amount Electrolyte Additives for Aqueous Zinc Batteries

Advanced Energy Materials, EarlyView.
Large‐amount additives primarily modify the bulk electrolyte by coordinating with Zn2+ or reshaping the hydrogen‐bond network, thereby altering the overall solution chemistry. In contrast, trace‐amount additives mainly operate at the electrode–electrolyte interface, regulating Zn deposition through electric double‐layer modulation, interfacial ...
