Feb 25, 2022 (Nanowerk News) Researchers from the University of Turku, Finland, found that the axis of rotation of a black hole in a binary system is tilted more than 40 degrees relative to the axis of stellar orbit. The finding challenges current theoretical models of black hole formation. The...
Chemically programmed nanotranslators facilitate communication between microorganisms from different kingdoms
Feb 25, 2022 (Nanowerk Spotlight) Bacteria use chemical signals to communicate with one another through a process called quorum sensing, which allows a population of single-celled microbes to work like a multicellular organism. Originally discovered in the early 1970s in unusual bioluminescent marine bacteria, it is now believed that all...
New evidence proves acceleration of quasar outflows at scale of tens of parsecs
Feb 25, 2022 (Nanowerk News) Dr. HE Zhicheng and his coworkers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences created a new way to measure the physical properties of galactic ionized gas, and discovered the acceleration of quasar outflows at the scale...
Novel nanoparticle-based anode materials for lithium-ion batteries
Feb 25, 2022 (Nanowerk News) Lithium-ion batteries (LIBs), known for their longevity, excellent charge storage characteristics, high energy density, and high operating voltage, have become the cornerstone of portable electronics, electronic vehicles, and the alternate energy economy. Manipulating the electrode material of LIBs is the most decisive and feasible method...
A new, Inexpensive metal hydroxide-organic frameworks speed the production of oxygen from water
Feb 25, 2022 (Nanowerk News) An electrochemical reaction that splits apart water molecules to produce oxygen is at the heart of multiple approaches aiming to produce alternative fuels for transportation. But this reaction has to be facilitated by a catalyst material, and today’s versions require the use of rare and...
Using proteins for engineered nanoelectronics
Feb 25, 2022 (Nanowerk News) Proteins are among the most versatile and ubiquitous biomolecules on earth. Nature uses them for everything from building tissues to regulating metabolism to defending the body against disease. Now, a new study shows that proteins have other, largely unexplored capabilities. Under the right conditions, they...
Development of a diamond transistor with high hole mobility
Feb 24, 2022 (Nanowerk News) Using a new fabrication technique, NIMS has developed a diamond field-effect transistor (FET) with high hole mobility, which allows reduced conduction loss and higher operational speed (Nature Electronics, "High-mobility p-channel wide-bandgap transistors based on hydrogen-terminated diamond/hexagonal boron nitride heterostructures"). This new FET also exhibits normally-off...
Microparticles show ability to turn in reverse, paving the way for microfluidic devices
Feb 24, 2022 (Nanowerk News) In a new study from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers have identified how a self-organized vortex of rotating microparticles in a fluid will reverse direction when an electric stimulus is interrupted and then reapplied with the same orientation, providing fundamental...
Scientists invent imaging method to assess quality of 3D-printed metal parts
