Since the early days of nanotechnology, people have used the scanning tunnelling microscope (STM) to manipulate atoms either mechanically or from the force due to charge injection. More recently researchers have noted that charge injected from an STM tip can manipulate molecules some distance away, by “remote control”. Now experiments have visualised the quantum mechanical […]
A technique called cryogenic near-field infrared microscopy has allowed researchers to observe how the electrical properties of the correlated insulator vanadium oxide (V2O3) evolve as it switches from being a metal to an insulator
Researchers at the University of Wollongong in Australia and the University of Texas at Dallas in the US have succeeded in fabricating stretchy, electrically conductive textiles based on Spandex and carbon nanotubes. The composite yarns, which were literally knitted together, could be used to make actuators and sensors for use in applications such as artificial […]
The nitrogen-vacancy (NV) defect in diamond can be used as a magnetometer to characterise the broadband magnetic fields generated by hard-disk write heads, according to new experiments by researchers in Germany and the UK. The new work could help further miniaturize these devices so that they can store more data….. http://nanotechweb.org/cws/article/tech/66356 A write head
Researchers in the US and Spain have developed a new way to assemble plasmonic nanoparticles using an optical technique that they have dubbed plasmon-enhanced thermophoresis. The technique, which relies on optically controlling a temperature field gradient, requires much less power than traditional methods such as optical tweezers. It could assemble nanoparticles into functional superstructures and […]
Reports of the element silicon – a king pin of the electronics industry for the past five decades – in the topical form of a 2D material have animated the community. Yet the discovery is not without dispute. While studies of multilayer ‘silicene’ report many intriguing properties, debate has flared over the ability to realize […]
