Environmentally Friendly Chemistry with Organophosphorus Syntheses in Focus [PDF]

, 2014
The use of the microwave (MW) technique has many advan tages in organophosphorus chemistry. MW irradiation may replace a catalyst, or simplify a catalytic system. New reactions may also become possible under MW irradiation. In most cases, microwaves just

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

Advanced 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

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

Advanced Science, EarlyView.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

Polyelectrolyte Multilayer: Caged PTFE Particles in Water for Continuous, Sonochemical H2O2 Synthesis

Advanced Science, EarlyView.
A yolk–shell PTFE‐based composite (YSP) enables tunable, robust hydrophobic–water interfaces for efficient, on‐demand sonocatalytic H2O2 generation and pollutant degradation. ABSTRACT The use of polytetrafluoroethylene (PTFE) particles to promote sonochemical H2O2 production has attracted growing interest, as cavitation bubbles formed at or near their ...

WGM Single‐Molecule Validation of pH‐Dependent Molecular Energetics at Gold Nanointerfaces: Influence of Buffer Molecules on Glyphosate Ligand Binding

Advanced Science, EarlyView.
Single‐molecule optical sensing reveals how pH and buffer molecules regulate glyphosate interactions with gold nanorods. Combined experiments and theoretical calculations show that changes in molecular charge and competition from buffer species determine whether glyphosate binds transiently or persistently.
