May 03, 2022 (Nanowerk News) For zeolites, a class of minerals used in industrial and chemical processes, smaller may be better. Synthesizing small zeolites only a few nanometers across could make them more effective and efficient. How small can they go? Around three nanometers is the limit, according to new...
Ruthenium atoms on copper nanowire mesh a more environmentally friendly way to produce ammonia
May 03, 2022 (Nanowerk News) A dash of ruthenium atoms on a mesh of copper nanowires could be one step toward a revolution in the global ammonia industry that also helps the environment. Collaborators at Rice University’s George R. Brown School of Engineering, Arizona State University and Pacific Northwest National...
Magnetism helps futuristic cell research
May 03, 2022 (Nanowerk News) Scientists at Korea's Daegu Gyeongbuk Institute of Science and Technology (DGIST) have successfully sorted individual cells according to their size by making them jump off magnetic trampolines and into different clustering rooms. They published their results in the journal Advanced Science ("Magnetophoretic Micro-Distributor for Controlled...
Dual membrane offers hope for long-term energy storage
May 03, 2022 (Nanowerk News) A new approach to battery design could provide the key to low-cost, long-term energy storage, according to Imperial College London researchers. The team of engineers and chemists have created a polysulfide-air redox flow battery (PSA RFB) with not one, but two membranes. The dual membrane...
Search reveals eight new sources of black hole echoes
May 03, 2022 (Nanowerk News) Scattered across our Milky Way galaxy are tens of millions of black holes — immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black holes are dark by definition, except on the rare occasions when they feed. As...
Spacecraft navigation uses x-rays from dead stars
May 03, 2022 (Nanowerk News) The remnants of a collapsed neutron star, called a pulsar, are magnetically charged and spinning anywhere from one rotation per second to hundreds of rotations per second. These celestial bodies, each 12 to 15 miles in diameter, generate light in the x-ray wavelength range. Researchers...
