Researchers at the Harbin Institute of Technology in China and the University of Michigan in the US are reporting on a new high surface area 3D composite made from reduced graphene oxide loaded with lithium iron phosphate nanoparticles. The material, assembled layer by layer, has a reversible lithium storage capacity as high as 148 mA […]
Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been produced in the lab, and the researchers believe that they could provide valuable insights into the angular momentum of light. On […]
Electron pairing without superconductivity has been seen for the first time by a team of physicists in the US. Confirming a prediction made in 1969, the electron pairs were spotted in strontium titanate using a single-electron transistor. The observation could provide useful insights into the nature of superconductivity, and perhaps even help in the design […]
Researchers at the Delft University of Technology in The Netherlands say they have succeeded in detecting individual DNA-bound proteins using solid-state nanopores for the first time. The technique could form the basis of a high-speed method to probe DNA-protein interactions – useful for DNA sequencing and for detecting the biomarkers in genetically inherited diseases…. http://nanotechweb.org/cws/article/tech/61188 […]
Researchers at the University of California, San Francisco, say they have a developed a new type of thin-film, biocompatible cell-encapsulation device from a polymer called polycaprolactone. The structure might be employed in cell replacement therapy to treat diseases like diabetes…….. http://nanotechweb.org/cws/article/tech/61200 The device
Nanostructured networks lend certain attributes of nanoparticles to macroscale systems
Researchers at Imperial College London and the Houston Methodist Research Institute in Texas say they have made biocompatible porous silicon nanoneedles that can efficiently deliver nucleic acids and nanoparticles into biological cells without damaging them. The needles can deliver these therapeutics into live cells that are normally difficult to transfect and the technique might help […]
A new type of metallic state of matter has been discovered by an international team of researchers studying a superconductor made from carbon-60 molecules or “buckyballs”. The team found the new state after changing the distance between neighbouring buckyballs by doping the material with rubidium. The study reveals that the material has a rich combination […]
Researchers in Germany, Moldova and Australia have developed a new way to build 3D architectures of semiconducting crystallites by growing gallium nitride (GaN) nano- and micro-buds on an aerographitic “tree”. The technique might be used to create flexible composites as next-generation nanomaterials for electronic, photonic and sensor applications….. http://nanotechweb.org/cws/article/tech/61134 3D aerographite
Researchers in Italy have made the first “bionicomposite” from carbon nanotubes or graphene and spider silk. The resulting fibres, which are the toughest and strongest ever measured, were produced by simply placing the spiders in a box and spraying them with water containing the carbon nanomaterials. The reinforced silk could find use in a wide […]
“Grand Challenges Thailand” launched Bangkok, Thailand (8May) – Deputy Prime Minister of Thailand announced the Launch of the Grand Challenges Thailand,
Although interactions are at the core of most advances in nanoscale science, research projects usually study just a few interactions at a time. Now researchers have come up with a design strategy to make and study networks of billions of interacting nanowires using a combination of top-down and bottom-up fabrication and traditional electronic measurement technology. […]
Researchers in the Korea and US say they have made amorphous indium-gallium-zinc oxide thin-film transistors that are completely soluble in water. The transient devices, which “disappear” once they have served their purpose, might be used in a wide range of new technologies, such as temporary, biodegradable medical implants, environmental sensors, and hardware for secure data […]
Researchers at Northwestern University in the US say they have printed the first biocompatible 3D graphene-based composite from liquid ink. The 3D structure is strong and flexible with electrical conductivities of 800 S/m, which is 10 times higher than previously reported values for 3D printed carbon materials. The composite also appears to help regenerate damaged […]
Researchers at the King Abdullah University of Science and Technology in Saudi Arabia (KAUST) say they have succeeded in designing a new type of nanotube tunnelling field-effect transistor (TFET) that has a much higher drive current than TFETs made from nanowires. The new TFET also switches on and off faster while running on less power […]
