Jun 05, 2023 (Nanowerk News) What the international team of researchers actually set out to do was to detect a mysterious chemical object: a dielectron in solution. A dielectron is made up of two electrons, but unlike an atom, it has no nucleus. Up to now, scientists have been unable...
Shining a light on neuromorphic computing
Jun 05, 2023 (Nanowerk News) AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system - both hardware and software combined - has been a decades-long challenge. Engineers at the University of Pittsburgh...
Smart surgical implant coatings provide early failure warning while preventing infection
Jun 05, 2023 (Nanowerk News) Newly developed “smart” coatings for surgical orthopedic implants can monitor strain on the devices to provide early warning of implant failures while killing infection-causing bacteria, University of Illinois Urbana-Champaign researchers report. The coatings integrate flexible sensors with a nanostructured antibacterial surface inspired by the wings...
Imaging agents light up two cancer biomarkers at once to give more complete picture of tumor
Jun 05, 2023 (Nanowerk News) Cancer surgeons may soon have a more complete view of tumors during surgery thanks to new imaging agents that can illuminate multiple biomarkers at once, University of Illinois Urbana-Champaign researchers report. The fluorescent nanoparticles, wrapped in the membranes of red blood cells, target tumors better...
Disks, spikes and clouds
Jun 05, 2023 (Nanowerk News) The detection of gravitational waves produced by the merger of black holes is teaching us a lot about the properties of these extreme objects. A team of researchers in the group of Gianfranco Bertone at the University of Amsterdam is devising new techniques to extract...
AI for discovering where and how nanoparticles bind with proteins
Jun 05, 2023 (Nanowerk News) Identifying whether and how a nanoparticle and protein will bind with one another is an important step toward being able to design antibiotics and antivirals on demand, and a computer model developed at the University of Michigan can do it. The new tool could help...
3D printed nanocomposite sensor for water pollution monitoring
Jun 05, 2023 (Nanowerk News) A new form of low-cost, 3D-printed water pollution sensor could make a splash in the world of environmental monitoring, its developers say. A team of researchers from universities in Scotland, Portugal and Germany developed the sensor, which can help detect the presence of very low...
Quantum effects detected in hydrogen and noble gas collisions
Jun 05, 2023 (Nanowerk News) A Freie Universität Berlin research team headed by quantum physicist Professor Christiane Koch has demonstrated how hydrogen molecules behave when they collide with noble gas atoms such as helium or neon. In an article published in the journal Science ("Tomography of Feshbach resonance states"), the...
Carbon-based stimuli-responsive nanomaterials: classification and application
Jun 05, 2023 (Nanowerk News) Carbon-based stimuli-responsive nanomaterials are gaining much attention due to their versatility, including disease diagnosis and treatment. They work under endogenous (pH, temperature, enzyme, and redox) or exogenous (temperature, light, magnetic field, ultrasound) stimuli. Carbon-based stimuli-responsive nanomaterials can be used as smart materials with dynamically tunable...
Buckle up! A new class of materials is here
Jun 02, 2023 (Nanowerk News) Usually, the two characterizations of a material are mutually exclusive: something is either stiff, or it can absorb vibrations well – but rarely both. However, if we could make materials that are both stiff and good at absorbing vibrations, there would be a whole host...
