Engineers have discovered a way to grow graphene nanoribbons with desirable semiconducting properties directly on a conventional germanium semiconductor wafer. This breakthrough could allow manufacturers to easily use graphene nanoribbons in hybrid integrated circuits, which promise to significantly boost the performance of next-generation electronic devices.
Graphene has number of interesting properties that have led researchers to suggest either modifying components of Li-ion batteries, or using graphene as the energy-storage medium instead as promising solutions.
Scientists have created a solid-state memory technology that allows for high-density storage with a minimum incidence of computer errors. The memories are based on tantalum oxide, a common insulator in electronics.
The Hybrid Photonic Mode-Synthesizing Atomic Force Microscope will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.
To see proteins in their native environment, scientists can blast powerful X-rays at tiny volumes of proteins in solution. Resulting 'diffraction patterns' can then be interpreted to reconstruct information about the protein's molecular structure. An emerging technique called fluctuation X-ray scattering could provide more detail than traditional solution scattering.
Scientists have developed a new hydrogel that works like an artificial muscle - quickly stretching and contracting in response to changing temperature. They have also managed to use the polymer to build an L-shaped object that slowly walks forward as the temperature is repeatedly raised and lowered.
Scientists have succeeded in combining two established measurement techniques for the first time: near-field optical microscopy and ultra-fast spectroscopy. Computer-assisted technology developed especially for this purpose combines the advantages of both methods and suppresses unwanted noise. This makes highly precise filming of dynamic processes at the nanometer scale possible.
A team of polymer physicists and chemists has developed a way to create an ultra-soft dry silicone rubber. This new rubber features tunable softness to match a variety of biological tissues, opening new opportunities in biomedical research and engineering.
