POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

The latest geodynamics in Central Asia: primary and secondary mantle melting anomalies in the context of orogenesis, rifting, and lithospheric plate motions and interactions

Геодинамика и тектонофизика, 2017
A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting.

Highly Robust Membrane Electrode Assembly Using Engineered Dual‐Phase Iridium Oxide Catalysts Breaking the Activity–Durability Trade‐Off in Proton Exchange Membrane Water Electrolysis

Advanced Science, EarlyView.
The dual‐phase iridium oxide catalyst was synthesized via a hard‐template‐assisted method, overcoming the conventional activity–durability trade‐off observed in Ir‐based catalysts. The HDP‐IrOx exhibits excellent catalytic activity and long‐term stability through the synergistic coupling between amorphous and crystalline phases, offering new insights ...

Compositional Tuning and Surface Restructuring Synergistically Enhance Perovskite Ferrite Catalysts for Hydrogen Evolution in a Membrane‐Less Electrolyzer

Advanced Energy Materials, EarlyView.
In this work, a self‐restructuring Fe‐based perovskite catalyst is developed, leveraging in situ amorphization to achieve a “self‐improving” behavior for hydrogen evolution. When integrated into a custom‐built membrane‐less electrolyzer, the system demonstrates a record‐breaking 1000 h stability, providing a robust and practical pathway for the ...

Morphology of the Reykjanes ridge junction with the rift zones of Iceland

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
The joint zone between subaquatic Reykjanes Ridge and Icelandic rift zones known as Reykjanes Rift Zone is a unique transform zone formed in conditions of interaction between the mantle plume and the mid-oceanic ridge.

Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, EarlyView.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.

Late Cenozoic intraplate volcanism as a trigger for hydrothermal venting in the Arctic southwestern Eurasia Basin

Communications Earth & Environment
Intraplate volcanism has occurred for the last 35 million years within Northeast Atlantic and Arctic margins, including the western Barents Sea, Svalbard, and northern Greenland. Earlier studies have suggested that some of this volcanism might be sourced

Covalent Organic Framework–Carbon Nanotube Core–Shell Nanohybrids for Enhanced Catalytic Site Utilization of Molecular Catalysts in CO2 Electroreduction

Angewandte Chemie International Edition, EarlyView.
Covalent organic framework–carbon nanotube (COF–CNT) core–shell nanohybrids are developed as an efficient platform to enhance the site utilization of molecular catalysts for electrochemical CO2 reduction. The well‐defined nanostructure promotes catalytic site accessibility, achieving CO turnover frequencies among the highest reported to date.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...
