Battery technology hasn't kept pace with advancements in portable electronics, but the race is on to fix this. One revolutionary concept being pursued by a team of researchers in New Zealand involves creating "wearable energy harvesters" capable of converting movement from humans or found in nature into battery power.
Queen's researchers have discovered that nanoparticles, which are now present in everything from socks to salad dressing and suntan lotion, may have irreparably damaging effects on soil systems and the environment.
At Karlsruhe Institute of Technology (KIT), researchers of the DFG Center for Functional Nanostructures succeeded in specifically cultivating cells on three-dimensional structures. The fascinating thing is that the cells are offered small "holds" in the micrometer range on the scaffold, to which they can adhere. Adhesion is possible to these holds only, not to the remaining structure.
Participants of this year's edition of the European Commission's Nano - Safety for Success Dialogue met under the heading of assessing the science and issues at the science / regulation interface. The event, organised by Health and Consumers Directorate General of the European Commission, took place in Brussels on 29-30 March 2011.
Researchers at the University of Warwick have developed a gold plated window as the transparent electrode for organic solar cells. Contrary to what one might expect, these electrodes have the potential to be relatively cheap since the thickness of gold used is only eight nanometers.
Modifying a protein from a plant much favored by science, researchers at the University of California, San Diego School of Medicine and colleagues have created a new type of genetic tag visible under an electron microscope, illuminating life in never-before-seen detail.
NASA and co-researchers from the United States, South Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969.
Making DNA sequences being passed through nanochannels a thousand times thinner than a human hair to the point that they take on the form of diminutive spaghetti. This is an innovative technique, known as DNA stretching, and is one of the lines of research in which CIC microGUNE is working, and about which they have already published two scientific articles and are shortly to apply for a patent.
A very simple bench-top technique that uses the force of acoustical waves to create a variety of 3D structures will benefit the rapidly expanding field of metamaterials and their myriad applications - including "invisibility cloaks".
