Ring of Plasmonics

The image shows a special plasmonic structure. On top of a gold layer a larger ellipse was created with electron beam lithography and ion beam etching. Subsequently, an additional gold layer was deposited. In the deeper ellipse structure eight smaller plasmonic ring structures were milled with the FEI Helios 650. The outer ellipse structure should enhance the signal of the smaller plasmonic ring structures.

Sub-micron pre-solar grain from outer space

A 250nm pre-solar grain was isolated from the substrate using FEI Quanta 3D-FEG. The grain is seen on top of the center pillar right under the Pt cap. The process is extremely delicate and precise, thanks to the stability of this FIB system. The sample is from a meteorite somewhere from outer space and the pre-solar grain was first identified in it by its unique isotopic signature.

Expanded Vermiculite

Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. In lightweight plaster and concrete, vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.
