Expanded Vermiculite

Courtesy of Mr. FRANCISCO RANGEL

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.

Atomic Structure of a Family of Amyloid Fibrils

Courtesy of Dr. Anthony Fitzpatrick

Pictured are the atomic-resolution structures of three amyloid polymorphs against a (falsely coloured) background image of the fibrils taken with a transmission electron microscope. Determining the fibril structures, and defining the major structural elements and interactions contributing to their hierarchical self-assembly, provides insight into the formation of polymorphic amyloid in a range of protein deposition disorders including Alzheimer’s and Parkinson’s diseases.

Dendritic cell

Courtesy of Prof. David Pérez-Morga

False-colored SEM image of a migrating mouse dendritic cell (5.2 µm), showing membrane projections known as lamellipodia (green). Dendritic cells are sentinels of the immune system that are posted in peripheral tissues, ingest intruders and then migrate to the lymphoid organs. There, they expose some of their digested protein fragments (antigens) using their cell membrane as a showcase, report on the intruder and interact with- and instruct effector immune cells known as T-lymphocytes.
