A multi-institutional team of scientists has taken an important step in understanding where atoms are located on the surfaces of rough materials, information that could be very useful in diverse commercial applications, such as developing green energy and understanding how materials rust.
Today, the Office of Science and Technology Policy issued a Request for Information (RFI) seeking suggestions for Nanotechnology-Inspired Grand Challenges for the Next Decade. A Grand Challenge is an ambitious but achievable goal that requires advances in science and technology to achieve, and that has the potential to capture the public's imagination.
A complete description of nanoscale thermal transport is a fundamental problem that has defied understanding for decades. Here, researchers uncover a new regime of thermal transport near nanoscale structures, where counterintuitively, nanoscale hot spots cool more quickly when placed close together than when they are widely separated.
An international research group has developed a method for measuring crystal vibrations in graphene. Understanding these vibrations is a critical step toward controlling future technologies based on graphene.
Heat may be the key to killing certain types of cancer, and new research has yielded unexpected results that should help optimize the design of magnetic nanoparticles that can be used to deliver heat directly to cancerous tumors.
Researchers have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3D-bioprinter. They also added carbon nanotubes to create electrically conductive material.
Scientists report the development of two novel devices that derive power directly from evaporation - a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car.
Researchers have solved the long-standing conundrum of how the boundary between grains of graphene affects heat conductivity in thin films of the miracle substance - bringing developers a step closer to being able to engineer films at a scale useful for cooling microelectronic devices and hundreds of other nano-tech applications.
Researchers published first experimental results showing that ordinary nanocrystals possess intrinsic chirality and can be produced under normal conditions as a half-and-half mixture of mirror images of each other.
Researchers have developed a new technique for visualizing light propagation through an optical nanofiber. The result is a non-invasive measurement of the fiber size and shape and a real-time view of how light fields evolve along the nanofiber.
