A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism - one of the four fundamental forces in the universe, and harnessed in all electronic devices - may not accurately account for the behavior of atoms in exotic, highly charged states.
A smile can say more than a thousand words, the saying goes. Orthodontics can help improve the appearance and position of people's teeth and jawbones, for better functioning teeth and more attractive smiles. In recent years, dental correction orthodontics have used braces made from clear plastic polymer to good effect, but now they are hoping to improve on this with help from nanotechnology.
A philosopher, a scientist and a software engineer have come together to propose a new centre at Cambridge to address developments in human technologies that might pose "extinction-level" risks to our species, from biotechnology to artificial intelligence.
Military uniforms of the future may offer a new layer of protection to wearers thanks to research at the UMass Amherst and elsewhere, developing a nanotube-based fabric that repels chemical and biological agents
Researchers at the CEA, CNRS and Joseph Fourier University, in Grenoble and Saclay, have developed two new cobalt-based materials that may be used to replace platinum, a rare and expensive metal, in producing hydrogen from water (electrolysis).
Researchers have taken the first step towards building graphene-based components. They successfully managed to increase the graphene conduction electrons' spin-orbit coupling by a factor of 10,000 - enough to allow them to construct a switch that can be controlled via small electric fields.
Properties of several of the most external atomic layers of materials can be studied at Mazovia Centre for Surface Analysis by a number of modern techniques. Just opened at the Institute of Physical Chemistry of the Polish Academy of Sciences, Warsaw, Poland, the Centre provides a spectrum of surface analysis tools including a state-of-the-art scanning electron microscope and specialised spectroscopic equipment for surface studies in high and ultra high vacuum.
In a new study, using tools including those found at the Synchrotron Radiation Center, scientists have developed a process for making a never-before-seen, atomically thin, composite material containing ordered layers of graphene and nanocrystals of graphene monoxide.
It is merely the arrangement of the carbon that makes it look so different. Highly ordered carbon makes a hard gemstone, incoherent and powdery carbon is more appropriate for a barbecue or writing letters. High pressures and temperatures can change the properties of carbon, and graphite becomes diamond. Researchers at the Leibniz Institute for New Materials were surprised to observed similar changes when monitoring nanoparticles.
