Aug 21, 2024 (Nanowerk News) The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these formulas don’t work in every situation. To compensate, they have added ad hoc “correction factors”...
New computational method simulates nanostructure formation with applications in catalysis and medicine
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...
Researchers coax nanoparticles to reconfigure themselves
Aug 19, 2024 (Nanowerk News) A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, according to a new study by researchers at the...
Real-time cardiovascular monitoring with novel hybrid smart stent system
Aug 19, 2024 (Nanowerk Spotlight) Cardiovascular diseases remain a leading cause of death worldwide, with atherosclerosis being a primary contributor. The narrowing of blood vessels due to plaque buildup can lead to life-threatening conditions, prompting the development of various interventional treatments. Stents, small mesh tubes inserted into arteries to keep...
