Zinc‐Mediated Photodegradation of Nitrophenols in Aqueous Solution: Devising Environmental Mitigation Strategies With Ultrafast Spectroscopic Insights

Electron, EarlyView.
We implement a suite of steady‐state and time‐resolved spectroscopic techniques to elucidate the zinc‐mediated photodegradation of nitrophenols in aqueous solution. From ultrafast electronic spectroscopy of aci‐nitrophenol on femtosecond‐to‐nanosecond timescales to tracking photoproducts with absorption and vibrational signatures (through ground‐state ...

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Titanium Dioxide Induced Immobilization of Small Platinum Nanoparticles on Carbon Spherogels: A Strategy Towards Stable and Efficient Electrocatalysts for the Hydrogen Evolution Reaction

Small, EarlyView.
Platinum nanoparticles are immobilized on hollow carbon spherogels using supercritical deposition, enabling precise control over nanoparticle size, loading, and spatial distribution. Incorporation of an internal TiO2 sublayer in the hollow sphere support induces enhanced metal–support interactions, markedly improving hydrogen evolution activity and ...

Can Entropically Unfavorable Topological Hydrogen‐Bonded Networks Form From Tetrakis‐ or Pentakis(4‐Carboxyphenyl)benzene Derivative?

Small, EarlyView.
1,2,3,5‐Tetrakis‐ and 1,2,3,4,5‐pentakis(4‐carboxyphenyl)benzene derivatives (1235CPB and 12345CPB) form H‐bonded networks with sql‐ and cem‐topologies, respectively. Furthermore,1235CPB forms a more complicated cqe‐topological network structure with three types of voids in crystalline states under the same crystallization condition, although the ...

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...
