The world's smallest tunnels have a width of a few nanometers only. Researchers from Karlsruhe Institute of Technology (KIT) and Rice University, USA, have dug such tunnels into graphite samples. This will allow structuring of the interior of materials through self-organization in the nanometer range and tailoring of nanoporous graphite for applications in medicine and battery technology. Results are now presented in the scientific journal Nature Communications (DOI: 10.1038/ncomms2399).
Researchers at Syracuse University's Department of Biomedical and Chemical Engineering at L.C. Smith College of Engineering and Computer Science are studying the toxicity of commonly used nanoparticles, particles up to one million times smaller than a millimeter that could potentially penetrate and damage cell membranes.
Looking toward improved batteries for charging electric cars and storing energy from renewable but intermittent solar and wind, scientists at Oak Ridge National Laboratory have developed the first high-performance, nanostructured solid electrolyte for more energy-dense lithium ion batteries.
Each year, Clarkson University is permitted to nominate up to four outstanding undergraduates for the prestigious Goldwater Scholarship. Nominees must intend to pursue research careers in science, math or engineering.
It stiffens when heated and retains moisture a hundred times better than other gels. Chemists at Radboud University Nijmegen have created a gel made from helical polymers. The molecules twist together to form a ‘nano rope’, from which strong, stiff networks are produced. What is unusual is that a solution of the material is liquid when cold and turns into a gel when warmed – exactly the opposite of what happens to gelatine, for example. The leading scientific journal Nature published a paper showing how the ‘super gel’ works and its properties on 24 January. Together with the business community, the researchers are also developing various biomedical applications for this extraordinary gel.
The Nanotechnology Platform Project is a project which was commissioned by Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT) with the aim of producing research results that will lead to innovations, in which 25 research institutions with leading-edge nanotechnology facilities and equipment in the three fields of Microstructural Characterization, Nanofabrication, and Molecule & Material Synthesis will provide opportunities for researchers in industry, academia, and government agencies throughout Japan to use those facilities.
The strong binding of gold on electronically modified calcium oxide can now be understood in detail. In a computational study, researchers Jenni Andersin, Janne Nevalaita, Karoliina Honkala and Hannu Häkkinen at the University of Jyväskylä Nanoscience Center have shown how redox chemistry entirely determines the adsorption strength of gold on the modified oxide where one metal atom is replaced with molybdenum. The study was funded by the Academy of Finland.
Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to University at Buffalo researchers.
Researchers at the Aalto University School of Chemical Technology have applied atomic layer deposition (ALD) technique to the synthesis of thermoelectric materials. Converting waste energy into electricity, these materials are a promising means of producing energy cost-effectively and without carbon dioxide emissions in the future.
Two teams of researchers from The University of Texas at Dallas have been chosen to help a $194 million national network create the technologies of the next generation.
