Because of the causes due to kinetics and gas-solid reprecipitation and sintering mechanisms, in a silicon nitride (MgO doped) porous body, an exaggerated whiskers and ribbon-like whiskers growth thrusting agglomerates of uprooted smaller Si3N4 particles by suspending them into the void of the porosity

The arrays of nickel nanowires have been produced by electro-deposition of nickel into the pores of porous alumina membranes. The membrane has been resolved by chemical etching and free standing nanowires perpendicular to a substrate have been obtained. Due to their ferromagnetic properties, the nanowires have possible applications in high density magnetic recording media. The picture shows a cross section view of the nickel nanowire array.

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.

False-colored SEM image of the surface of a kidney stone. Urolithiasis is a common condition, with a prevalence of about 10%. Various types of urinary calculi have been described upon their mineral content and/or their morphology. The depicted stone is made of calcium phosphate crystals.

Ceria has been extensively used as catalyst support for different reactions at Division of Catalysis and Chemical Processes (DCAP)/INT. This is mainly due to its redox properties, which are fundamental for catalyst stability.
