(Phys.org)—By carefully placing a tiny piece of diamond within a few nanometers of a carbon nanotube, and then sending an electric current through the nanotube, researchers have designed a device that could one day form ...
Even if you don't know it by name, everyone is familiar with Newton's third law, which states that for every action, there is an equal and opposite reaction. This idea can be seen in many everyday situations, such as when ...
(Phys.org)—While some advanced humanoid robots already look eerily lifelike, robots in the future may actually become partly alive. Currently, researchers are working on integrating living cells and other biological components ...
(Phys.org) -- Mechanical energy is all around us, whether in the form of a vehicle's vibrations, ocean waves, or vibrating train tracks. However, much of this energy is irregular and oscillatory - for example, road bumps ...
(PhysOrg.com) -- In order to develop next-generation electric vehicles, solar energy systems, and other clean energy technologies, researchers need an efficient way to store the energy. One of the key energy storage devices ...
A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex ...
