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 ...

Peroxynitrite-mediated lipid oxidation and nitration: mechanisms and consequences
, 2009 Lipid oxidation and nitration represents a novel area of research of relevance in the understanding of inflammatory processes. Peroxynitrite, the product of the diffusion-limited reaction between nitric oxide and superoxide anion, mediates oxidative ...

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries
Advanced Science, EarlyView.A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving

Solid acid catalysts for fluorotoluene nitration using nitric acid
, 2003 Fluorotoluenes have been nitrated regioselectively in the liquid phase under mild conditions using solid acid catalysts. Excellent yields were obtained with 70% nitric acid as nitrating agent.

Advanced Science, EarlyView.A one‐pot, aqueous, and scalable method for synthesizing chiral lanthanide supramolecular emitters using terbium and threonine is reported. The aqueous solution of these chiral emitters displays the following features: (i) 100 % transparency, (ii) tunable luminescence and CPL, and (iii) a pH feedback loop that controls the “on‐off” states of ...

Nitration of the methylnaphthalenes
, 1965 The nitration of naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene has been studied under a variety of conditions. Relative rates by competition and isomer distributions have been determined using gas chromatographic analyses. The derived partial

Advanced Science, EarlyView.Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Studies in the nitration of thioxanthene
, 1952 Thioxanthene is a heterocyclic sulfur compound first synthesized by Graebe and Schultess in 1891. It was prepared by the pyrolysis of phenyl o-tolyl sulfide and in a second and better method, by the reduction of thioxanthone to thioxanthene. Thioxanthene

Copper-Catalyzed Tyrosine Nitration
, 2016 Tyrosine nitration, often observed during neurodegenerative disorders under nitrative stress, is usually considered to be induced chemically either by nitric oxide and oxygen forming nitrogen dioxide or by the decomposition of peroxynitrite.
