Coâ‚‚free molten metal catalysts for hydrogen production improve efficiency by up to 36.3%
Development of selenium-promoted molten metal catalysts with improved activity and hydrogen production efficiency. Credit: Korea Institute of Chemical Technology (Krict) Korean researchers have developed advanced liquid metal catalysts incorporating selenium (SE) to increase the efficiency of turquoise hydrogen production. Turquoise hydrogen is produced through methane (CHâ‚„) pyrolysis, and produces solid carbon as a by-product, without releasing carbon (COâ‚‚) while producing…

Research reveals that a quantum ‘umbilical cord’ connects the metal and insulator states of many materials
DFT+DMFT calculations for copper oxide waterfalls. Credit: Nature Communications (2025). DOI: 10.1038/s41467-024-55465-7 Some materials exhibit a kind of umbilical cord between different quantum states. Researchers at the Vienna University of Technology have shown that this “umbilical cord” is common to many materials. This is the basic principle of quantum theory. Certain physical quantities may only assume very specific values. All…

Single-atomic metal layer reveals unexpected spin-polarized current control by light
When circularly polarized light is applied to a thallium-lead alloy, the majority of the electrons “up-spin” and flow in the correct direction (spin-polarized current). Credit: Taniuchi et al. 2025 Researchers at the University of Tokyo have demonstrated that the direction of spin-polarized current is restricted to only one direction in a single atomic layer of a thallium-lead alloy when irradiated…

Team synthesizes cost-effective and durable non-precious metal alloy as an alternative to iridium oxide anodes
Credit: Yoshikazu Ito Despite the growing importance of hydrogen as a future energy source, transporting gaseous hydrogen safely and on a large scale remains challenging. Researchers are exploring ways to transport hydrogen in the form of liquid methylcyclohexane (MCH) by reacting it with toluene. One such approach is organic hydride electrosynthesis. In this process, toluene is transferred from the cathode…

Heavy metal toxicity in the ocean increases: How climate change will affect ocean pollutants
Conceptual illustration of natural and anthropogenic sources, sinks, and transport pathways of trace element pollutants in coastal ecosystems that may interact with climate change (CC) factors. Credit: Communications Earth & Environmental (2024). DOI: 10.1038/s43247-024-01679-y Toxic trace elements such as lead, mercury, arsenic, and cadmium occur naturally in small amounts in coastal waters. However, the contribution of human activities such as…
