- 16/09/2021 Next generation electronics: Expanding the possibilities with silver nanowires Today's nanoscale technologies are sophisticated enough to be applied in an endless number of useful devices, from sensors in touch screen devices and household appliances to wearable biosensors that can monitor chemical levels in our blood, muscle movement, breathing and pulse rate. In addition, there are technologies for precision devices such as high-resolution scanning probe microscopes which enable one to visualize surfaces not only at the atomic level, but even the individual atoms themselves.
- 14/09/2021 Physicists develop new unique scanning tunneling microscope with magnetic cooling to study quantum effects Scanning tunneling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years to explore the world of nanoscopic phenomena. A new approach is now creating new possibilities for using the devices to study quantum effects.
- 07/09/2021 Highly durable biomimetic nanotrough electrodes for proton exchange membrane fuel cells Membrane electrode assembly is the core part of proton exchange membrane fuel cells (PEMFCs). However, the high consumption of platinum and poor durability of carbon supported platinum nanoparticles (Pt/C) in the conventional cathode prohibit the large-scale commercialization of fuel cell vehicles.
- 02/09/2021 A peculiar state of matter in layers of semiconductors Scientists around the world are developing new hardware for quantum computers, a new type of device that could accelerate drug design, financial modeling, and weather prediction. These computers rely on qubits, bits of matter that can represent some combination of 1 and 0 simultaneously. The problem is that qubits are fickle, degrading into regular bits when interactions with surrounding matter interfere. But new research at MIT suggests a way to protect their states, using a phenomenon called many-body localization (MBL).
- 31/08/2021 Redox-less electron transfer in ‘weird’ material could allow powerful batteries A material has been identified that should have the strange property of being able to both store and lose electrons without the usual associated redox reactions. The redox-less process, predicted to occur in a fluoride-ion based material, could enable long-lasting, high capacity next generation batteries.
- 26/08/2021 Progress in algorithms makes small, noisy quantum computers viable Instead of waiting for fully mature quantum computers to emerge, researchers have developed hybrid classical/quantum algorithms to extract the most performance -- and potentially quantum advantage --
- 24/08/2021 Theories predict 2D nanofluidic channels showing nonlinear conduction function as memory-effect transistors A team of researchers at Sorbonne Université has developed a way to show 2D nanofluidic channels carrying out nonlinear conduction functions as memory-effect transistors, using theory and simulations. In their paper published in the journal Science, the group describes their work with aqueous electrolytes confined in a two-dimensional gap between graphite layers and what they learned from it. Yaqi Hou and Xu Hou with Xiamen University have published a Perspective piece in the same journal issue outlining work involved in replicating the ways that neurons communicate using ionic and neurotransmitter conduction, and the work done by the team in France.
