Rice University lab combines graphene nanoribbons with tin oxide for improved anodes Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes. Proof-of-concept anodes – the part of the battery that stores lithium ions – built with graphene nanoribbons (GNRs) and tin oxide showed an initial capacity better than the theoretical capacity of tin...

Door To Clean-Energy Alternatives Opened With Nanoparticle
2013-06-13 15:40:07

Pennsylvania State University Cheaper clean-energy technologies could be made possible thanks to a new discovery. Led by Raymond Schaak, a professor of chemistry at Penn State University, research team members have found that an important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. The results of the research will be published in the...

Ecole Polytechnique Fédérale de Lausanne A colloid is a substance spread out evenly inside another substance. Everyday examples include milk, styrofoam, hair sprays, paints, shaving foam, gels and even dust, mud and fog. One of the most interesting properties of colloids is their ability to self-assemble — to aggregate spontaneously into well-defined structures, driven by nothing but local interactions between the colloid's particles. Self-assembly has been...

Light-Carved ‘Nano-Volcanoes’ Could Help With New Drug Delivery Technologies
2013-06-13 14:37:12

North Carolina State University Researchers from North Carolina State University have developed a method for creating “nano-volcanoes” by shining various colors of light through a nanoscale “crystal ball” made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies. The researchers create the nano-volcanoes by placing spherical, transparent polymer nanoparticles directly onto...

Polymer Structures Serve As 'Nanoreactors' For Producing Nanocrystals With Uniform Sizes, Shapes
2013-06-12 14:09:01

Georgia Institute of Technology Tiny chemistry Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal...

Toolbox For Nanoparticle Manipulation Expanded With New Microfluidic Method
2013-06-06 14:03:40

University of Illinois at Urbana-Champaign Researchers at the University of Illinois at Urbana-Champaign have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. “This method is a first-of-its-kind tool for manipulation and trapping of small nanoparticles in solution,” explained Charles M. Schroeder, an assistant professor in the...

Many solids are produced from melting. Depending on how quickly they cool off, invariably, internal tensile stresses begin to build up. One example are Prince Rupert's Drops, or Dutch tears: you can hit their thick end with a hammer without breaking them while a slight pressure applied to their thin end is enough to shatter the entire tear. The properties of safety or even gorilla glass are determined to a large extent by their internal tensile stresses. However, until now, our understanding...


Word of the Day
