Iron nanoparticles encapsulated in a rust-preventing polymer coating could hold potential for cleaning up groundwater contaminated with toxic chemicals.
In Harvard’s Pierce Hall, the surface of a small germanium-coated gold sheet shines vividly in crimson. A centimeter to the right, where the same metallic coating is literally only about 20 atoms thicker, the surface is a dark blue, almost black. The colors form the logo of the Harvard School of Engineering and Applied Sciences (SEAS), where researchers have demonstrated a new way to customize the color of metal surfaces by exploiting a completely overlooked optical phenomenon.
Magnolia Solar Corp. (Magnolia Solar), developer of thin-film solar cell technologies employing nanostructured materials and designs, announced that Dr. Roger E. Welser, the Chief Technology Officer of its wholly owned subsidiary, Magnolia Solar Inc., presented a paper at the 2012 MRS Fall Meeting in Boston, MA, entitled "Nanostructured Transparent Conductive Oxides for Photovoltaic Applications," as part of a special session on photovoltaic technologies.
A joint project between New Zealand-based companies GNS Science and Resene Paints will develop a new low-cost way of producing a powder containing metal oxide nanoparticles that can be readily incorporated into existing paint manufacturing methods.
Nanocoatings are opening up new market opportunities in the global coatings arena. Properties such as corrosion resistance, flame retardancy, UV stability, gloss retention, and chemical and mechanical properties are improved significantly using nanomaterials.
Rice University researchers have settled a long-standing controversy over the mechanism by which silver nanoparticles, the most widely used nanomaterial in the world, kill bacteria.
Scientists at the University of Twente’s MESA+ Institute for Nanotechnology have developed a new material that is not only extremely water repellent but also extremely oil repellent.
A Rice University laboratory has come up with a one-size-fits-almost-all way to measure batches of single-walled nanotubes that promises to help researchers and industry make more efficient use of the wondrous carbon material.
An invisible quick response (QR) code has been created by researchers in an attempt to increase security on printed documents and reduce the possibility of counterfeiting, a costly problem for governments and private industry.
Grit blasting of metal surfaces, a routine surface preparation technique prior to painting, is expensive, labor-intensive, time-consuming, and generates a large amount of hazardous, powdery waste
