Nanosheet-based electronics could be one drop away

“A surprisingly simple method improves ‘drop casting’ fabrication of tiled nanosheets that could be used in next-generation electronic devices. All you need is a pipette and a hotplate. Scientists at Japan’s Nagoya University and the National Institute for Materials …

New way to control electrical charge in 2D materials: Put a flake on it

“Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material, alpha-RuCl3, on top of it. A paper published in the journal Nano …

Supercapacitors challenge batteries

“A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid …

Perfect transmission through barrier using sound: research team led by Professor Xiang Zhang proves for the first time a century-old quantum theory

“The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat. A research team led by Professor Xiang …

Researchers invent method to ‘sketch’ quantum devices with focused electrons

“Technique is 10,000 faster than previous methods, and can create active nanostructured gates directly below two-dimensional materials such as graphene It has long been a dream to invent new materials from the “top down” choosing which atoms go where …

Ultrafast gas-flows through tiniest holes in 2D membranes

“Researchers from National Graphene Institute at The University of Manchester and University of Pennsylvania have identified ultrafast gas-flows through the tiniest holes in one-atom-thin membranes, in a study published in Science Advances. The work - alongside another study from University of …

Sheets of carbon nanotubes come in a rainbow of colors

“Study: Nanotube films come in 466 colors, could be used in electronics, solar panels Nanomaterials researchers in Finland, the United States and China have created a color atlas for 466 unique varieties of single-walled carbon nanotubes. The nanotube color atlas …

Toward imperceptible electronics that you cannot see or feel

“Researchers from Osaka University fabricated ultrathin, flexible, transparent sensors with cross-aligned silver nanowire microelectrodes fabricated using print technique that are scalable and require minimal raw materials Transparent electronics—such as head-up displays that allow pilots to read flight data while …

Atom-thin transistor uses half the voltage of common semiconductors, boosts current density

“University at Buffalo researchers are reporting a new, two-dimensional transistor made of graphene and the compound molybdenum disulfide that could help usher in a new era of computing. As described in a paper accepted at the 2020 IEEE International Electron …

Stretchable micro-supercapacitors to self-power wearable devices

“A stretchable system that can harvest energy from human breathing and motion for use in wearable health-monitoring devices may be possible, according to an international team of researchers, led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in Penn …
