From e-waste to gold: the path to CO₂ sustainability
Synthesis of TTF-COF and TPE-COF. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-55156-3 A Cornell University-led research team has developed a method to extract gold from e-waste and use the recovered precious metal as a catalyst to convert the greenhouse gas carbon dioxide (CO2) into organic materials. According to Amin Zadehnazari, a postdoctoral researcher in Yongkeun Joh Associate’s Alireza Abbaspourrad lab, this…

Study tracing the path of Ebola to the skin surface
Credit: Unsplash/CC0 Public Domain Ebola is a deadly bleeding disease caused by a virus that is endemic in parts of East and West Africa. Most people know that the main route of human-to-human transmission is through contact with the body fluids of an infected person. However, in more recent outbreaks, such as the 2013-2016 Ebola outbreak in West Africa, infectious…

The angles where atoms meet could provide a path to new materials under extreme conditions
Credit: Nano Letters (2024). DOI: 10.1021/acs.nanolett.4c02395 How can we design materials that are stronger and lighter? What about new materials for extreme conditions such as jet engines and spacecraft? Associate Professor of Materials Science and Engineering in the PC Rossin College of Engineering and Applied Sciences at Lehigh University The answer, says one Fadi Abdel-Jawad, may lie in the infinitesimal…

Theoretical physicists reveal how twisting layers of material creates mysterious electron path deflection effects
(Left) Atomic force microscopy image showing a sample of twisted layers of WS2 (a material made of tungsten and sulfur). Scale bar represents 4 micrometers (4 millionths of a meter). (Right) Diagram showing how to measure the Hall effect (lateral voltage) in twisted materials. The red arrow represents the path of the electron, and V0 and VH are the voltages…
