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 ...

Sulfonated, Disulfide‐Bridged Polymer Networks for Atmospheric Water Harvesting

Small, EarlyView.
Atmospheric water harvesting is a promising solution to the water crisis. Here, disulfide‐containing hyper‐crosslinked‐style polymers are prepared by combined Friedel–Crafts alkylation and thiol self‐condensation. Exhibiting exceptional uptake capacities, the polymers demonstrate dynamic bonding behavior.

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

Small, EarlyView.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

Small, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Ba[C(CN)3]2 and Pb[C(CN)3]2: Two Remarkably Different Heavy Main‐Group Metal Bistricyanomethanides

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Metathesis reactions of either barium dichloride, BaCl2, or lead dichloride, PbCl2, respectively, with Ag[C(CN)3] in water yielded single crystals of anhydrous Ba[C(CN)3]2 and Pb[C(CN)3]2. Ba[C(CN)3]2 crystallizes in the monoclinic space group P21/n (no. 14) with the lattice parameters a = 437.98(3) pm, b = 1685.36(11) pm, c = 1398.87(9) pm, β = 96.541(

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 ...

Clearing the Air: How Fine Particulate Matter Regulations Reshape Farmland Values in U.S. Corn and Soybean Regions

Journal of Agricultural Economics, EarlyView.
ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.
