Researchers from Tokyo Metropolitan University have shown that a newly engineered catalyst made of gold nanoparticles supported on a metal oxide framework shows breakdown of ammonia impurities in air, with excellent selectivity for conversion to nitrogen gas. Importantly, it is effective at room temperature, making it suitable for everyday air purification systems. The team successfully identified the mechanism behind this behavior, paving the way towards the design of other novel catalytic materials.
Researchers from Tokyo Metropolitan University have shown that the tunable hydrophobic nature of dense siloxane gels is strongly correlated with their catalytic activity, explicitly demonstrating how molecules with different hydrophobic nature at the molecular level interact differently with surfaces of differing hydrophobicity. This is also the first time a siloxane gel has been shown to be highly effective for the reaction of silyl ethers, commonly used as a protecting agent.
A new system devised by researchers at MIT can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a Coast Guard cutter, the system pinpointed a motor with burnt-out wiring that could have led to a serious onboard fire.
A Rice University-led study discovers a mechanism by which molecules affect the plasmonic response of gold nanorods. The mechanism could be used to enhance applications like catalysis that involve plasmon-driven chemistry.
Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge. The techniques developed so far have produced rather poor results. However, University of Groningen scientists, led by Professor of Photophysics and Optoelectronics Maria Antonietta Loi, have now cracked it -- using a blade and a dipping solution. The results were published in the journal Nanoscale on March 15, 2019.
Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.
The method developed by Juho Karhu in his PhD thesis work is a first step towards creating a precise measuring device.
Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems - but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories. An international collaboration from Japan and Massachusetts unveiled an improved algorithm to track motor performance and speed estimation. Experiments demonstrate the potential effectiveness and advantages of the proposed algorithm: fast speed estimation transient and ease of tuning.
Researchers have discovered that a bacterium found in camel crickets is capable of breaking down lignin -- the stuff that makes wood tough -- opening new research pathways for the development of biofuels and chemical manufacturing. The study also highlights the potential inherent in using ecosystem analysis as a tool for targeting research into the identification of commercially valuable microorganisms with industrial applications.
A new system for synthesizing quantum dots across the entire spectrum of visible light drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control.
