Graphene-Based Nanomat Could Lead to Next-Generation Catalysts
Microwave oven cooks up solar cell material
University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used ...
Durable carbon nanotube sensors can be etched with mechanical pencils
Carbon nanotubes offer a powerful new way to detect harmful gases in the environment. However, the methods typically used to build carbon nanotube sensors are hazardous and not suited for large-scale production.
Engineers create ultra-sensitive artificial skin
Graphene on boron nitride work may lead to breakthrough in microchip technology
(Phys.org) -- Graphene is the wonder material that could solve the problem of making ever faster computers and smaller mobile devices when current silicon microchip technology hits an inevitable wall. Graphene, ...
An unlikely route to ferroelectricity
(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain ...
Electron hopping in graphene oxide leads to highly sensitive sensing
Electronic nose prototype may be worn for safety-sniffing
3-D, after-the-fact focus image sensors invented
(PhysOrg.com) -- At the heart of digital photography is a chip called an image sensor that captures a map of the intensity of the light as it comes through the lens and converts it to an electronic signal.
Barrier to faster graphene devices identified and suppressed
These days graphene is the rock star of materials science, but it has an Achilles heel: It is exceptionally sensitive to its electrical environment.
Researchers find best routes to self-assembling 3-D shapes
Material chemists and engineers would love to figure out how to create self-assembling shells, containers or structures that could be used as tiny drug-carrying containers or to build 3-D sensors and electronic ...
New stretchable electronics device promises to make cardiac ablation therapy simpler
In an improvement over open-heart surgery, cardiologists now use catheters to eliminate damaged heart tissue in certain patients, such as those with arrhythmias. But this, too, can be a long and painful procedure ...
Researchers control conduction, surface states in topological insulator nanoribbons
In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their ...
New high-sensitivity electronic skin can feel a butterfly's footsteps
Stanford researchers have developed an ultrasensitive, highly flexible, electronic sensor that can feel a touch as light as an alighting fly. Manufactured in large sheets, the sensors could be used in artificial ...
