Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor -- meaning that it could be used to make "spintronic" devices, which rely on magnetic force to operate, rather than electrical currents.
'Nanobiomaterials: Development and Applications' gives you a broad, interdisciplinary view of current developments as well as new findings and applications in bionanomaterials. The book brings together the work of international contributors who are actively engaged at the forefront of research in their respective disciplines.
Researchers in China present a simple synthetic strategy by gas flow directed assembly of a unique interlocking alignment of the Si nanowires (SiNWs) to produce, for the first time, a flexible transparent and self-standing silicon nanowires paper, which consists of interconnected SiNWs with the diameter of about 10 nm via simply free-catalyst thermal evaporation in a vertical high-frequency induction furnace.
A new technique lets scientists efficiently resolve elements' locations in three dimensions. The technique combines scanning transmission electron microscopy and X-ray energy dispersive spectrometry with a new detector arrangement and a brighter electron beam. The result is a three-dimensional map of the elements' placement on a sample smaller than a single blood cell.
Chemists, physicists and computer scientists at the University of Warwick have come together to devise a new powerful and very versatile way of controlling the speed and direction of motion of microscopic structures in water using what they have dubbed chemically 'motorised microscopic matchsticks'.
A revolutionary new solar energy technology that turns water into steam without boiling the entire container of water has become the basis for new devices to sanitize medical and dental instruments and human waste in developing countries.
Scientists at the University of Southampton are to study the 3D architecture of healthy human tissues down to the nanometre scale (one billionth of a meter), to develop regenerative cell techniques for musculoskeletal repair.
Researchers from the University of Pennsylvania have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.
A nanoparticle shaped like a spiky ball, with magnetic properties, has been uncovered in a new method of synthesising carbon nanotubes by physicists at Queen Mary University of London and the University of Kent.
Making large quantities of reliable, inexpensive nanoparticles for batteries, solar cells, catalysts and other energy applications has proven challenging due to manufacturing limits. A Cornell research team is working to improve such processes with a $1.5 million National Science Foundation (NSF) grant to support scalable nanomanufacturing and device integration.
