Japanese researchers have developed a catalyst that selectively degrades polyurethane in mixed plastic waste, allowing for the separation and chemical recycling of complex materials. The breakthrough opens up new possibilities for waste management, particularly in industries such as end-of-life vehicle recycling and mattress disposal.
University of Delaware researchers have developed a spray-jet method that recovers precious metals and other materials from used hydrogen-energy devices. The new recycling approach uses no harsh chemicals or burning, preserving the membrane itself while extracting platinum and iridium separately.
Researchers at Rice University developed a new catalyst that reduces iridium needed in proton exchange membrane water electrolyzers, maintaining industrial-level performance for over 1,500 hours. The innovation uses just one-sixth as much iridium as conventional systems, addressing a significant economic and supply chain bottleneck.
Researchers have discovered a new material that matches or exceeds the performance of commercial iridium-based materials, but at a fraction of the cost. The breakthrough was achieved using a powerful new tool called a megalibrary, which rapidly screened vast combinations of metals to find a suitable alternative.
A new catalyst structure featuring mesoporous single-crystalline Co3O4 doped with atomically dispersed iridium (Ir) has been proposed as a potential pathway toward cost-effective hydrogen production. The material achieves efficient use of Ir while maintaining stability, reducing leaching during reaction.
Scientists identify the origin of magnetic moment enhancement in an iridium-doped iron-cobalt alloy through high-throughput X-ray measurements. The study reveals that Ir addition leads to increased electron localization and spin-orbit coupling, resulting in enhanced magnetic moments.
Researchers from Tokyo Metropolitan University developed a new dye that strongly absorbs second near-IR radiation, transforming it to heat. This breakthrough enables clearer imaging and better delivery of heat for therapies in deep tissue medicine.
Researchers at HZB developed a new P2X catalyst requiring less iridium than commercial materials, showing remarkable stability and different mechanisms for oxygen evolution. The study provides valuable information about catalyst performance and stability.
Researchers have developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. The use of inexpensive nickel compounds replaces costly and rare iridium, leading to significant advancements in understanding fundamental catalysis mechanisms.
