Aug 20, 2024 (Nanowerk News) Researchers from the group of Prof. Carles Bo, at the Institute of Chemical Research of Catalonia (ICIQ-CERCA), have described a computational methodology that simulates complex processes involving different chemical species and diverse conditions. These processes lead to the formation of nanostructures called polyoxometalates (POMs), with...
Explanation found for X-ray radiation from black holes
Aug 20, 2024 (Nanowerk News) Researchers at the University of Helsinki have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas. Using...
Planets contain more water than thought
Aug 20, 2024 (Nanowerk News) We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets – planets that orbit another star outside our solar system. “It...
Smart fabrics detect and repel pathogens to prevent hospital infections
Aug 20, 2024 (Nanowerk Spotlight) In healthcare settings, textiles like bed sheets, scrubs and curtains can harbor dangerous pathogens, facilitating the spread of infections among patients and staff. Despite advances in antimicrobial fabrics, controlling the transmission of bacteria, viruses and other microorganisms via hospital textiles remains an ongoing challenge. Previous...
Towards ultrathin sources of entangled photons
Aug 20, 2024 (Nanowerk News) Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources. Quantum entanglement is the cornerstone of...
Novel ratchet with geometrically symmetric gear driven by asymmetric surface wettability
Aug 20, 2024 (Nanowerk News) The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typically consisting of a gear and a pawl, which restricts the movement...
