Scientists uncovered an anomalous metallic behavior in an otherwise insulating ceramic material. The team used ultrashort light pulses with a wide range of colors to watch what happens when the insulating quasi two-dimensional material La2CuO4 (LCO) becomes a three-dimensional metal through laser irradiation. • Email to a friend • Researchers have produced a gel from cellulose fibres and biodegradable nanoparticles that liquifies when pressed through the nozzle of a 3D printer, but then quickly returns to its original shape. • Email to a friend • Researchers presented the test results of an innovative oncotherapy technology based on hyperthermia - heating a tumor to a certain temperature due to nanoparticles introduced into it. The drug based on cobalt ferrite nanoparticles cured 100% of the mice with intestinal cancer from the experimental group. • Email to a friend • New experiments have placed the best limits yet on impermeability of graphene and other two-dimensional materials to gases and liquids. The work has also revealed that the carbon sheet can act as a powerful catalyst for hydrogen splitting, a finding that promises cheap and abundant catalysts in the future. • Email to a friend • Scientists have a new strategy for 'trapping and zapping' antibiotic resistant genes, the pieces of bacteria that, even though theirs hosts are dead, can find their way into and boost the resistance of other bacteria. • Email to a friend • Researchers have developed a method to produce a wood-derived, fully bio-based, and environmentally friendly flexible electronic circuit. They tailored the wood nanostructure to create a wood film with high transparency, flexibility, and strong mechanical properties. This material compares favorably with previously published two-dimensional cellulose-based materials developed for electronics or structural applications. This flexible circuit highlights the fact that wood can be used as a feedstock, with the potential to displace petroleum-based material for high-value products. • Email to a friend • Scientists have developed powerful tools to unmask the diversity of amyloid fibrils, which are associated with Alzheimer?s disease and other neurodegenerative disorders. They made the breakthrough by developing gold nanoparticles that combine with cryogenic transmission electron microscopy, to provide rapid and unprecedented images of fibrils. • Email to a friend • The high conversion of dark to bright excitons in long carbon nanotubes can lead to more efficient optoelectronics devices. • Email to a friend • Using a simple post-annealing process, scientists created a flexible organic cell that degrades by less than 5 percent over 3,000 hours in atmospheric conditions and that simultaneously has an energy conversion ratio - a key indicator of solar cell performance - of 13 percent. • Email to a friend • Nanoengineers developed a safety feature that prevents lithium metal batteries from rapidly heating up and catching fire in case of an internal short circuit. • Email to a friend • |
