New form of Carbon Nanostructure is Stronger Than Diamond
Researchers from the University of California, Irvine, and a few other institutions present a new class of nanolattices that is constructed from closed-cell plate-architectures.
Single Layer of Carbon Atoms Can Boost Gigahertz Signals to Terahertz Frequencies
A new experiment by Physicist Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P) showed that the single layer of carbon atoms (graphene) can transform electronic signals at gigahertz frequencies into higher-frequency terahertz signals.
New Graphene Foam Stays Squishy Even at the Coldest Temperatures
Typical elastic materials made from flexible polymers lose their elasticity at about 55 degrees Celsius. Of course, materials do exist that can handle frigid temperatures without breaking, but elasticity and ductility are generally compromised at these low temperatures.
Generating Electricity Just from Thin Air
Yao and his team designed a device and named ‘Air-gen’ and claimed that it can produce a sustained voltage of around 0.5 volts across a 7-micrometer-thick film, with a current density of around 17 microamperes per square centimeter and the driving force behind this energy generation is the humidity that is naturally present in the air.
Next Generation Sound Device: Graphene-Based Sound Device
A team of researchers at UC Berkeley and Berkeley Lab found that graphene has mechanical properties that will make it ideally suited for wide-band ultrasonic...
WIFI Signals Turned Into Usable Power Source
A team of physicists at Massachusetts Institute of Technology (MIT) have now devised a blueprint to design a device that would be able to convert ambient terahertz waves,...
Do You have Color Blindness? No Worry! Contact Lens Based on Metasurface is on its way
Typically, humans can distinguish around 1 million colors but for some these numbers is not the same as others as their color perception is limited in...
Carbon Nanotubes Forecast When Vegetables Spoil And Buds Will Bloom
Timothy Swager, Darryl Fong, and colleagues at MIT and the Nanotechnology National Laboratory for Agriculture in Brazil used carbon nanotubes (CNTs)...
Nanosensor Knows When Plants Are Stressed
By tracking hydrogen peroxide (H2O2), MIT engineers were able to observe how plants respond to stresses such as injury, infection, and light damage using...
