The fabrication of many objects, machines, and devices around us rely on the controlled deformation of metals by industrial processes such as bending, shearing, and stamping. Is this technology transferrable to nanoscale? Can we build similarly complex devices and machines with very small dimensions? Scientists from Aalto University in Finland and the University of Washington in the US have just demonstrated this to be possible. By combining ion processing and nanolithography they have...

Understanding Glass Like Never Before

[ Watch the Video: Brownian Diffusion of a Colloidal Tetrahedral Cluster ] Michael Harper for redOrbit.com — Your Universe Online Scientists are insatiable people. Their never-ending quest to know the “how” and “why” of every little thing has brought us where we are today. As a result of tireless research, scientists have found a way to deliver robotic rovers into space, what materials are more conducive to the transference of data, and what happens...

New Way To Prevent Cracking In Nanoparticle Films Discovered
2012-10-15 14:33:36

Making uniform coatings is a common engineering challenge, and, when working at the nanoscale, even the tiniest cracks or defects can be a big problem. New research from University of Pennsylvania engineers has shown a new way of avoiding such cracks when depositing thin films of nanoparticles. The research was led by graduate student Jacob Prosser and assistant professor Daeyeon Lee, both of the Department of Chemical and Biomolecular Engineering in Penn´s School of Engineering and...

Shape Matters In DNA Nanoparticle Therapy
2012-10-12 10:49:44

Particles could become a safer, more effective delivery vehicle for gene therapy Researchers from Johns Hopkins and Northwestern universities have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases. This study, to be published in the Oct. 12 online edition of the journal Advanced Materials, is also noteworthy because this...

Total market value is expected to reach $53.5 billion in 2017 after increasing at a five-year compound annual growth rate (CAGR) of 19.9%. Drug...

Nickelblock Is The Love-hate Relationship Between Nickel And Battery Electrodes
2012-09-28 13:04:12

Images show how nickel, which enhances battery capacity, also appears to hinder charging rates Anyone who owns an electronic device knows that lithium ion batteries could work better and last longer. Now, scientists examining battery materials on the nano-scale reveal how nickel forms a physical barrier that impedes the shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. Published last week in Nano Letters, the research also suggests a way to...

Clean Clothes Can Clear The Air

April Flowers for redOrbit.com - Your Universe Online A new laundry additive that contains microscopic pollution-eating particles may soon be on the market. The product, called CatClo, is the result of a collaboration between the University of Sheffield and the London College of Fashion. Initial support for the product came from the Engineering and Physical Sciences Research Council (ESPRC). Clothing would only need to be washed in the additive once because the nanoparticles of...

Positive results shown for cancer, Alzheimer´s and obesity drugs Nanoparticles have shown great promise in the targeted delivery of drugs to cells, but researchers at the University of Georgia have refined the drug delivery process further by using nanoparticles to deliver drugs to a specific organelle within cells. By targeting mitochondria, often called "the powerhouse of cells," the researchers increased the effectiveness of mitochondria-acting therapeutics used to treat cancer,...

Low-powered Nanotweezers May Benefit Cellular-level Studies By Demonstrating New Capabilities
2012-09-17 17:08:19

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. “We already know that plasmonic nanoantennas enhance local fields by up to several orders of magnitude, and thus, previously showed that we can use these structures with a regular CW laser source to make...
