Apr 07, 2022 (Nanowerk News) Extremely small arrays of magnets with strange and unusual properties can order themselves by increasing entropy, or the tendency of physical systems to disorder, a behavior that appears to contradict standard thermodynamics — but doesn’t. “Paradoxically, the system orders because it wants to be more...
Researchers engineer electrically tunable graphene devices to study rare physics
Apr 07, 2022 (Nanowerk News) An international team, co-led by researchers at The University of Manchester’s National Graphene Institute (NGI) in the UK and the Penn State College of Engineering in the US, has developed a tunable graphene-based platform that allows for fine control over the interaction between light and...
The use of photons to create an artificial quantum neuron
Apr 07, 2022 (Nanowerk News) Artificial intelligence algorithms are based on mathematical models called neural networks, inspired by the biological structure of the human brain, which is made up of interconnected nodes (neurons). Just as in our brain the learning process is based on the rearrangement of the connections between...

Laser additive manufacturing of Si/ZrO2 tunable crystalline phase 3D nanostructures
Apr 07, 2022 (Nanowerk News) A route for laser nano-printing of 3D crystalline structures was developed. The method employs ultrafast laser lithography, used as additive manufacturing tool for producing true 3D nanostructures, and combined with high temperature thermal post-treatment, converting the printed material into fully inorganic substance. The carried out...
Astronomers detect galactic space laser
Apr 07, 2022 (Nanowerk News) A powerful radio-wave laser, called a ‘megamaser’, has been observed by the MeerKAT telescope in South Africa. The record-breaking find is the most distant megamaser of its kind ever detected, at about five billion light years from Earth. The light from the megamaser has travelled...
Nerve stimulation with the help of implantable mini solar cells
Apr 07, 2022 (Nanowerk News) An international research team has successfully developed and tested a concept in which nerves are stimulated with light pulses. The method provides considerable advantages for medicine and opens up a wide range of possible applications. The technology enables completely new types of implants that can...
Microcavities as a sensor platform
