Nanoink High Density Tip Arrays for Polymer Pen Lithography Allows for high-throughput deposition of molecules

NanoInk announced today the availability of High Density (HD) Tip Arrays for Polymer Pen Lithography (PPL). These high-density elastomeric pen arrays are ideal for high-throughput deposition of ink materials. Similar to standard Dip Pen Nanolithography® (DPN®) with regular silicon nitride pens, High Density Tip Arrays can be used for the deposition of molecules with well-controlled …

Metallic Hydrogen: A Game Changing Rocket Propellant

Atomic metallic hydrogen, if metastable at ambient pressure and temperature could be used as the most powerful chemical rocket fuel, as the atoms recombine to form molecular hydrogen. This light-weight high-energy density material would revolutionize rocketry, allowing single-stage rockets to enter orbit and chemically fueled rockets to explore our solar system. To transform solid molecular …

Transformation thermodynamics: cloaking and concentrating heat flux

Optics Express – Transformation thermodynamics: cloaking and concentrating heat flux We adapt tools of transformation optics, governed by a (elliptic) wave equation, to thermodynamics, governed by the (parabolic) heat equation. We apply this new concept to an invibility cloak in order to thermally protect a region (a dead core) and to a concentrator to focus …

Simple, cheap way to mass-produce graphene nanosheets

Mixing a little dry ice and a simple industrial process cheaply mass-produces high-quality graphene nanosheets, researchers in South Korea and Case Western Reserve University report. Graphene, which is made from graphite, the same stuff as “lead” in pencils, has been hailed as the most important synthetic material in a century. Sheets conduct electricity better than …

Electrical control of a solid-state flying qubit

Nature Nanotechnology – Electrical control of a solid-state flying qubit Solid-state approaches to quantum information technology are attractive because they are scalable. The coherent transport of quantum information over large distances is a requirement for any practical quantum computer and has been demonstrated by coupling super-conducting qubits to photons1. Single electrons have also been transferred …

Promising Graphene Supercapacitor

An Electrochemical capacitors (ECs) that combines the power performance of capacitors with the high energy density of batteries would represent a significant advance in energy storage technology. This requires new electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional ECs that use activated carbon electrodes. Now …

Non-magnetic materials can be magnetically doped in high concentrations in a highly controlled way

Nanotechnologists from the University of Twente’s MESA+ and MIRA research institutes have developed a method for incorporating magnetic elements into non-magnetic materials in a highly controlled way. Using this technique, it is possible to drastically change the electrical behaviour of metals and even to give semiconductors magnetic properties. University of Twente researchers were able to …

Gene fusion in lung cancer afflicting never-smokers may be target for therapy

Smoking is a well-known risk factor for lung cancer, but nearly 25% of all lung cancer patients have never smoked. In a study published online today in Genome Research (www.genome.org), researchers have identified a previously unknown gene fusion event that could explain a significant proportion of lung cancer cases in never-smokers, and might serve as …
