Nanoindent on deformed copper imaged with channeling contrast. Nanoindentation is a tool to measure the hardness very localised at a low force. Therefore surface defects such as scratches or, as can be seen here, the oxide layer might have an influence on the measurement.

Aerators should be regularly kept cleaned or replaced. The mesh in the aerator can collect lead debris, and then leach this toxic metal into the water passing through it. Aerators cap the ends of most drinking-water faucets. In some cases, they’re used to conserve water by reducing a faucet’s maximum flow rate; in others their primary function is to concentrate the flow of water so that it delivers more pressure and cleaning power. But these little metal cages also collect debris. Including lead. And unless you’re regularly cleaning out those aerators, you might be developing a toxic mini gravel field through which your drinking water must pass before reaching your glass or coffee pot. Indeed, one lead poisoning case in North Carolina involved a child (see link below): www.dcwater.com/waterquality/faqs.cfm

The picture was taken after the growth by CVD of silicon nanowires on a copper foil with gold on top. When I saw it I remembered the perturbation caused by sun storms on magnetic field of the earth. These nanowires will be used to manufacture anodes of ion-Li batteries.

The Scanning Electron Microscope (SEM) image is of the head of an embryonic Zebrafish. This is a model organism currently being used for studies into the genetic causes of neurodegeneration. This research project involves Kim Wager, a Ph.D. student jointly supervised by Dr Claire Russell (RVC) and Professor Robert Harvey (UCL School of Pharmacy). The Zebrafish was imaged under a FEI Quanta 200F Scanning Electron Microscope. Firstly, the sample was chemically fixed in 4% (w/v) paraformaldehyde in 0.1M Sodium Cacodylate buffer, followed by dehydration in graduated alcohol and drying in a Leica Critical Point (CPD300) dryer. Prior to imaging, the specimen was given a 5nm gold coating in a Quorum Q150 Sputter coater and imaged at 5KV. In addition, a high tilt angle of 65 degrees enhanced the full structure of the head region. A high-resolution digital image was captured, imported into Photoshop and was artistically coloured by Ms Annie Cavanagh.

Hydroxyapatite is a form of calcium phosphate that has a large number of applications such as bone implants, and drug delivery systems. For each application, the use of calcium based materials is optimized by specifying their geometry, dimension, density, pore size, mechanical strength, purity, and chemical phase.

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.
