A pioneering new technique that could make light-based cancer treatment more effective and safer for patients, while reducing its cost, has been developed by researchers from the University of Sheffield.  Scientists at Texas Heart Institute (THI) and Rice University have used biocompatible fibres made of carbon nanotubes (CNTs) as electrical bridges to restore conductivity to damaged hearts.  A team of researchers from China, the U.S. and Japan has developed a way to strengthen graphene-based membranes intended for use in desalination projects-by fortifying them with nanotubes.  The team arrived at their results by imaging gold nanoparticles, with diameters ranging from 2 to 5 nanometres, via aberration corrected scanning transmission electron microscope.  Nanoparticles of less than 100 nanometres in size are used to engineer new materials and nanotechnologies across a variety of sectors.  For years, researchers have been trying to find ways to grow an optimal nanowire, using crystals with perfectly aligned layers all along the wire.  Ferroelectric materials have a spontaneous dipole moment which can point up or down.  Researchers have successfully demonstrated that hypothetical particles that were proposed by Franz Preisach in 1935 actually exist.  Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light.  Materials scientists at Duke University computationally predicted the electrical and optical properties of semiconductors made from extended organic molecules sandwiched by inorganic structures.
