FIB

Ti-rich Sulfide from Meteorite

Sub-micrometer grains of a Ti-rich sulfide phase were discovered in the Yamato 691 meteorite. The FIB was used at NASA-JSC Labs. to extract a thin x-section of the grains. Subsequent TEM analyses verified the composition and crystal structure of the phase and and a new mineral was discovered. In the picrure, the sub-micron grain of the new mineral is shown in yellow color.

Gallium Phosphide

Pyramidal shape (ice cream like) of a GaP nanocolumn tipped by a spherical ball containing Ga + In metallic liquid. The metallic ball is coverd by a carbon nanomembrane. The structure was grown by the Metallorganic Chemical Vapours Phase Technique. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.

Faucet Aerator III

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

Cross section of soft-drink plastic bottle label

This is a cross-section of the film that is used to produce the labels of soft-drink plastic bottles, such as cola. As can be seen on the image the internal structure of the film is more complex than one might think, containing different layer types and particles.
