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 ...

Heterogeneity in mantle carbon content from CO2-undersaturated basalts

Nature Communications, 2017
Melting dynamics are affected by the amount of carbon in the Earth’s mantle. Le Voyeret al. report undegassed carbon concentrations from olivine-hosted melt inclusions from the Mid-Atlantic Ridge finding that carbon content varies by two orders of ...

Colloidal Quasi‐2D Cs2AgBiBr6 Double Perovskite Nanosheets: Synthesis and Application as High‐Performance Photodetectors

Small, EarlyView.
Layered quasi‐2D Cs2AgBiBr6 nanosheets, with large lateral dimensions of up to 1.4 µm, which are only a few nanometers thick, were synthesized as a result of systematic investigation of the roles of ligands and reaction temperature. The nanosheets were used to develop high‐performance photodetectors, yielding detectivity in the order of 1012 Jones with

Hydrous Regions of the Mantle Transition Zone Lie Beneath Areas of Continental Intraplate Volcanism

Geochemistry, Geophysics, Geosystems
Great volumes of water are carried downward into the mantle transition zone (MTZ, 410–670 km depth) by subducting slabs. If this water is later drawn upward, the resulting mantle melting may generate continental intraplate volcanism (IPV).

Systemic Governance From Below: Story Telling to Empower Access to the Commons Through Mapping and Modelling: A Mixed Methods Approach

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Access to forests, farming land and the Citarum river is limited in Tarumajaya; furthermore, many do not own their own housing and are dependent on the public and private landowners in the area. The region of Tarumajaya faces significant challenges in access to crucial resources such as forests, farming land and the Citarum river, leading to a

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

Environmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

The effect of ilmenite viscosity on the dynamics and evolution of an overturned lunar cumulate mantle

Geophysical Research Letters, 2017
Lunar cumulate mantle overturn and the subsequent upwelling of overturned mantle cumulates provide a potential framework for understanding the first‐order thermochemical evolution of the Moon.

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

A Tilted Broad Plume Underneath the Greenland Cratonic Keels

Geophysical Research Letters
To advance our comprehension of the complex geological history and mantle dynamics in the North Atlantic region, we employ all available broadband seismic data recorded in Greenland to reveal an abnormal mantle transition zone (MTZ) structure.
