Minimally invasive surgery is increasingly used to target small lesions and a growing demand exists for miniaturized medical tools. These include microcatheters, articulated micro-forceps or tweezers to sense and actuate ...
In a recent report published on Science Advances, Andrew Seredinski and co-workers presented a graphene-based Josephson junction with dedicated side gates fabricated from the same sheet of graphene as the junction itself. ...
In a recent study on materials science and nanomedicine, Young-Geun Park and co-workers at the departments of Nanoscience, Nanomedicine and Materials Science and Engineering in the Republic of Korea developed an unconventional ...
When electrons that repel each other are confined to a small space, they can form an ordered crystalline state known as a Wigner crystal. Observing the fragile crystal is tricky, since it requires extreme conditions including ...
Understanding nonequilibrium phenomena to effectively control it is an outstanding challenge in science and engineering. In a recent study, Trond. I. Andersen and colleagues at the departments of physics, chemistry, materials ...
Scientists have dedicated intense work in recent years to convert environmental energy into electricity to meet the ongoing demands for a cleaner and more sustainable power source. Harvesting environmental mechanical energy ...
Scientists have recently developed a light controlled nano-switch to lay groundwork for atomic device development in nanotechnology. They engineered the switches at the nanoscale in a first step toward fully integrated electronic ...
Miniaturized semiconductor devices with energy harvesting features have paved the way to wearable technologies and sensors. Although thermoelectric systems have attractive features in this context, the ability to maintain ...
As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...
(Phys.org)—Researchers have used a simple inkjet printer to print a "bio-ink" of cyanobacteria onto a conductive surface, creating a biophotovoltaic cell. Unlike conventional photovoltaic cells that operate only when exposed ...
