| New product features with metallic nanoparticles Posted: 20 Jun 2013 04:14 AM PDT Scientists are developing new techniques for the production of metallic nanoparticles. A new production reactor, operating at atmospheric pressure, reduces the production costs of multicomponent particles. It enables the production of metallic nanomaterials, which are not yet commercially available, for research and product development needs.  |
| Alternative energy: A cooler way to clean hydrogen Posted: 19 Jun 2013 01:15 PM PDT A process known as ethanol steam reforming is creating opportunities for fuel cell researchers, thanks to the recent rise of the bioethanol industry. This technique generates hydrogen gas (H2) directly within fuel cell systems onboard vehicles by decomposing bioethanol in the presence of special catalysts -- an approach that could use current gasoline delivery infrastructures to power alternative energy transportation.  |
| Hybrid nanostructures: Getting to the core Posted: 19 Jun 2013 01:15 PM PDT Material scientists expect the new multifunctional properties of hybrid nanostructures will transform the development of high-performance devices, including batteries, high-sensitivity sensors and solar cells. These self-assembling nanostructures are typically generated by depositing ultrasmall objects with different properties on the surfaces of tiny semiconducting wires. However, the factors that govern their formation remain elusive, making these structures difficult to control and design.  |
| Posted: 19 Jun 2013 01:15 PM PDT A 'sandwich' of three iron alloy layers could help to create computer hard drives that can store more data than ever before. This new development, based on a new technology called heat-assisted magnetic recording (HAMR), could boost the capacity of disks.  |
