Albahaca stoma

At the center of the image is a stoma, is circular and is part of the skin of the leaves; their function is to allow breathing with the cells of the plant. Several trichomes are also observed, these are epidermal hairs that serve to protect, absorb or secrete substances.

Presolar Grain

This image shows a Sub-micron, nano meter sized pre-solar grain, isolated using FIB Qunta 3D-FEG, at the Johnson Space Center NASA. The grain is right under the carbon cap on the very top of the pillar shown in the picture. This sample is from a meteorite and the isolated grain showed, which later on experimentally proved, to be a pre-solar grain. This procedure of isolation made it possible to perform NANO-SIMS analysis and later on preparing a thin X-Section for TEM analysis on this really really precious grain. The study helped towards understanding the formation of stars in our galaxy as well as the origin of our own solar system.

Zinc crystals

Zinc crystals that have been adsorbed on the surface of an alginate gel after being subjected to a process of wastewater treatment. An important field of application of the alginates gels is the protection of the environment: alginate gels are used as adsorbents for the removal of heavy metals such as cadmium, zinc, lead, chromium and mercury in wastewater.

ESEM - Calcium sulfphate dihydrate.

The hydration of calcium sulphate hemihydrate (CaSO4.0,5H2O) leads to gypsum (calcium sulphate dihydrate – CaSO4.2H2O). It is a highly exothermic reaction which occurs by a dissolution/reprecipitation mechanism: when the hemihydrate is mixed with water, a fraction of it dissolves to give a saturated solution with respect to Ca2+ and SO4 2- ions, which is supersaturated with respect to calcium sulfphate dihydrate leading to nucleation and crystal growth. ESEM images taken from the hemihydrate hydration process. One can follow water adsorption to the hemihydrate at a 100% RH and the resulting needle-like crystals which result after water elimination.

Star Destroyer

TheraCal is a new light-curable dental material composed of calcium silicate and resin, for use as a pulp-capping material and liner, in restorative dentistry. The image shows a calcium silicate crystal seen in a sample from a study to evaluate the apatite forming ability of TheraCal, which is critical for new dentin formation.

Platinum Nanorods on Silicon

The image shows an array of freestanding Pt nanorods on silicon fabricated by electron beam induced deposition from the gas phase. The individual rods reveal a base diameter of about 80 nm and a hight of 1 µm. The wavy appearance was actually an artifact but too nice to be ignored. Image was post-colorized by Margit Wallner (FELMI).
