Strings that can vibrate forever (kind of)

 Nanotechnology News
 22 May 2024
Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to...

Ethylene from CO2: Building-kit catalyst

 Physics General News
 22 May 2024
Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms...

Recycling carbon dioxide into household chemicals

 Nanotechnology News
 22 May 2024
Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products....

Powering wearable devices with high-performing carbon nanotube yarns

 Nanotechnology News
 21 May 2024
Carbon nanotube (CNT) yarns are promising for flexible and fabric-type wearable materials that can convert waste heat into thermoelectricity. To improve the thermoelectric properties of CNT yarns, researchers dispersed CNT filaments in a highly viscous glycerol, enabling the production of CNT yarn...

Blueprints of self-assembly

 Nanotechnology News
 20 May 2024
Scientists have taken a step closer to replicating nature's processes of self-assembly. The study describes the synthetic construction of a tiny, self-assembled crystal known as a 'pyrochlore,' which bears unique optical properties. The advance provides a steppingstone to the eventual construction...

Expanding on the fundamental principles of liquid movement

 Nanotechnology News
 20 May 2024
We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile...

Ion irradiation offers promise for 2D material probing

 Nanotechnology News
 17 May 2024
Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions...

Magnetic imprint on deconfined nuclear matter

 Physics General News
 17 May 2024
Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study...
