Particle & Particle Systems Characterization
Researchers 'nanoweld' by applying light to aligned nanorods in solid materials
Researchers from North Carolina State University have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.

Titanium dioxide nanoreactor
Tiny particles of titanium dioxide are found as key ingredients in wall paints, sunscreens, and toothpaste; they act as reflectors of light or as abrasives. However with decreasing particle size and a corresponding change in their surface-to-volume ratio, their properties change so that crystalline titanium dioxide nanoparticles acquire catalytic ability: Activated by the UV component in sunlight, they break down toxins or catalyze other relevant reactions.

New technology in the magnetic cooling of chips
Luis Hueso, the CICnanoGUNE researcher, together with researchers from the University of Cambridge, among others, has developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened. The work has been published recently in the prestigious journal Nature Materials.

Painting with catalysts: Nano-engineered materials for detoxifying water by use of sunlight
Only light, aerial oxygen, and a catalyst are needed to remove pollutants from water. RUB researchers led by Prof. Radim Beránek collaborate with colleagues from seven different countries in order to develop a photocatalyst that is efficient enough to be profitable. The aim is to implement the newly developed photocatalysts into a liquid paint with which photoreactors can easily be coated. The EU supports the project within its 7th Framework Programme with 3.7 million Euro funding for three years.

Researchers create semiconductor 'nano-shish-kebabs' with potential for 3-D technologies
Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a "nano-shish-kebab," consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. But looks can be deceiving, as the nanowire and nanosheets are actually a single, three-dimensional structure consisting of a single, seamless series of germanium sulfide crystals. The structure holds promise for use in the creation of new, three-dimensional technologies.

New material interface improves functioning of non-silicon-based electronic devices
For the first time, researchers have designed a special material interface that has been shown to add to and to improve the functioning of non-silicon-based electronic devices, such as those used in certain kinds of random access memory. The new method could be used to design improved, more-efficient, multilevel and multifunctional devices, as well as enhanced nanoelectronic components -- such as non-volatile information storage and processing; and spintronic components

Forging a new periodic table using nanostructures
Northwestern University's Chad Mirkin has developed a new set of building blocks based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. Mirkin has built more than 200 different crystal structures with 17 different particle arrangements. Some of the lattice types can be found in nature, but many are new structures that have no naturally occurring mineral counterpart.

Not your conventional nucleic acids
Northwestern University's Chad Mirkin has invented and developed a powerful nanomaterial that could revolutionize biomedicine: spherical nucleic acids (SNAs). The novel arrangement of nucleic acids imparts interesting chemical and physical properties that are very different from conventional nucleic acids. Potential applications include using SNAs to carry nucleic acid-based therapeutics to the brain for the treatment of glioblastoma, the most aggressive form of brain cancer, as well as other neurological disorders such as Alzheimer's and Parkinson's diseases.

A quantum dot energy harvester
A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. The engines would be microscopic in size, and have no moving parts. Each would only produce a tiny amount of power but by combining millions of the engines in a layered structure, enough of them could make a notable difference in the energy consumption of a computer.

Detecting cocaine 'naturally'
Since the beginning of time, living organisms have developed ingenious mechanisms to monitor their environment. As part of an international study, a team of researchers has adapted some of these natural mechanisms to detect specific molecules such as cocaine more accurately and quickly. Their work may greatly facilitate the rapid screening -- less than five minutes -- of many drugs, infectious diseases, and cancers.
