Oct 18, 2023 (Nanowerk News) Since its initial discovery in 2004 at the University of Manchester, graphene has made a big splash in the scientific community. Its discoverers won a Nobel Prize in 2010 for developing the idea – then the race was on to find ways to produce and...
Scientists apply giant wave mechanics on a nanometric scale
Oct 18, 2023 (Nanowerk News) Researchers have shown how the principles of rogue waves – huge 30-metre waves that arise unexpectedly in the ocean – can be applied on a nano scale, with dozens of applications from medicine to manufacturing. Key Takeaways Researchers at the University of Warwick have discovered...
Researchers succeed in accelerating electrons using a nano device
Oct 18, 2023 (Nanowerk News) Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic...
From a five-layer graphene sandwich, a rare electronic state emerges
Oct 18, 2023 (Nanowerk News) Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire...
A paradigm shift in mechanobiology
Oct 18, 2023 (Nanowerk News) A research group from the University of Turku and Turku Bioscience Centre together with Misvik Biology Ltd in Finland have developed a new method for studying how cancer cells function in softer and stiffer tissue environments. This insight challenges the existing paradigm, opening up new...
Using AI to develop hydrogen fuel cell catalysts more efficiently and economically
Oct 18, 2023 (Nanowerk News) Proton exchange membrane hydrogen fuel cells (PEMFCs) used in hydrogen vehicles use expensive platinum catalysts to facilitate the oxygen reduction reaction at the anode. There are a vast number of elemental combinations and compositions that need to be explored to develop more efficient and cost-effective...
scientists develop a skin patch that painlessly delivers drugs into the body
Oct 18, 2023 (Nanowerk News) An affordable microneedle skin patch that delivers a controlled dosage of medicine directly into the body, eliminating the need for injections or oral medication, has been developed by a team led by scientists at the University of Bath. Key Takeaways Scientists at the University of...
A new view of all objects in the universe

The study also offers new ideas about how our universe may have started. The study is published in the latest issue of...
physicists boost microscopes beyond limits
Oct 17, 2023 (Nanowerk News) Ever since Antonie van Leeuwenhoek discovered the world of bacteria through a microscope in the late seventeenth century, humans have tried to look deeper into the world of the infinitesimally small. Key Takeaways Physicists at the University of Sydney have developed a method to surpass...
Discovery of nanoscale ferroelectricity in simple metal oxides paves way for advanced electronic devices
Oct 17, 2023 (Nanowerk News) A new study published in ACS Nano ("Robust Switchable Polarization and Coupled Electronic Characteristics of Magnesium-Doped Zinc Oxide") provides the first observation of nanoscale intrinsic ferroelectricity in magnesium-substituted zinc oxide thin films, i.e. metal oxide thin films with simple wurtzite crystal structures. Ferroelectrics akin to...
