Researchers at Hewlett Packard Labs in California, the University of Massachusetts Amherst and Seoul National University are reporting on a new low-current, self-rectifying memristor made from titanium ion electron traps in a niobium oxide matrix. The device might be used as an embedded memory on low-power chips and for storing data in Internet of Things (IoT) appliances......
Researchers at the University of Minnesota in Minneapolis have invented a new ultralow power technique to trap nanoparticles in the sub-10 nm gaps between two gold electrodes. The technique, which overcomes many of the problems encountered in traditional dielectrophoresis experiments, could help make portable biosensors.....http://nanotechweb.org/cws/article/tech/66547
Researchers at the University of Oxford in the UK and the Massachusetts Institute of Technology in the US are the first to combine experimental and theoretical approaches at the atomic level to study how monolayer molybdenum sulphide (a typical 2D material) fractures. Thanks to transmission electron microscopy observations, backed up with large-scale molecular dynamics simulations, they have found that atomically sharp cracks propagate throughout the material in a way that generates the least energy to break the material apart. The experiments reveal fundamental aspects of fracture mechanics that are simply not possible to see in thicker materials, and they could help to design more reliable nanodevices made from 2D structures.........http://nanotechweb.org/cws/article/tech/66614
By functionalizing the surface of a variety of nano-objects (such as nanowires, nanosheets, nanocubes and even biological cells) with polyphenols, researchers at the University of Melbourne in Australia say that they can turn them into superstructured assemblies. The technique, which literally transforms the nanobject into a LEGO brick-like structure with stubs, could be used to make devices like complex sensors, drug carriers, structures for carrying out complicated chemical reactions and even synthetic cells with sub-compartments.........http://nanotechweb.org/cws/article/tech/66617
