In nanotube growth, errors are not an option
At the right temperature, with the right catalyst, there's no reason a perfect single-walled carbon nanotube 50,000 times thinner than a human hair can't be grown a meter long. That calculation is one result of a study by collaborators at Rice, Hong Kong Polytechnic and Tsinghua universities who explored the self-healing mechanism that could make such extraordinary growth possible.

Study improves understanding of surface molecules in controlling size of gold nanoparticles
North Carolina State University researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles – with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.

University of Utah chemists use nanopores to detect DNA damage
Scientists worldwide are racing to sequence DNA -- decipher genetic blueprints -- faster and cheaper than ever by passing strands of the genetic material through molecule-sized pores. Now, University of Utah scientists have adapted this "nanopore" method to find DNA damage that can lead to mutations and disease.

Got mass? Princeton scientists observe electrons become both heavy and speedy
A Princeton University-led team of scientists has shown how electrons moving in certain solids can behave as though they are a thousand times more massive than free electrons, yet at the same time act as speedy superconductors.

Self-assembling nanocubes for next generation antennas and lenses
Researchers at the University of California, San Diego Jacobs School of Engineering have developed a technique that enables metallic nanocrystals to self-assemble into larger, complex materials for next-generation antennas and lenses. The metal nanocrystals are cube-shaped and, like bricks or Tetris blocks, spontaneously organize themselves into larger-scale structures with precise orientations relative to one another. Their findings were published online June 10 in the journal Nature Nanotechnology.

UCSB scientists synthesize first genetically evolved semiconductor material
In the not-too-distant future, scientists may be able to use DNA to grow their own specialized materials, thanks to the concept of directed evolution. UC Santa Barbara scientists have, for the first time, used genetic engineering and molecular evolution to develop the enzymatic synthesis of a semiconductor.

Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters.

A new spin on antifreeze
A team of researchers from Harvard University have invented a way to keep any metal surface free of ice and frost. The treated surfaces quickly shed even tiny, incipient condensation droplets or frost simply through gravity. The technology prevents ice sheets from developing on surfaces -- and any ice that does form, slides off effortlessly.

Nanoparticles in polluted air, smoke & nanotechnology products have serious impact on health
New groundbreaking research by scientists at Trinity College Dublin has found that exposure to nanoparticles can have a serious impact on health, linking it to rheumatoid arthritis and the development of other serious autoimmune diseases. The findings, published in 'Nanomedicine', have health and safety implications for the manufacture, use and ultimate disposal of nanotechnology products and materials. They also identified new cellular targets for the development of potential drug therapies in combating the development of autoimmune diseases.

A SMART(er) way to track influenza
Brown University researchers have created a reliable and fast flu-detection test that can be carried in a first-aid kit. The novel prototype device isolates influenza RNA using a combination of magnetics and microfluidics, then amplifies and detects probes bound to the RNA. The technology could lead to real-time tracking of influenza. Results are published in the Journal of Molecular Diagnostics.

Researchers develop a 'time bomb' to fight cardiovascular disease
Atherosclerosis, resulting in a narrowing of the arteries and the development of cardiovascular disease, is the leading cause of death worldwide. Until now, no treatment could target diseased areas exclusively, in order to increase drug efficacy and reduce side effects. To help bridge this gap, a group of researchers from UNIGE, HUG and the University of Basel have developed a veritable 'time bomb,' a treatment that can recognize the diseased areas and treat only them.
