An area of Pt thin film deposited on the surface of a polished fine grained sample. Subjected to tensile mechanical stress, substrate and thin film show a different plastic behavior. Mixed together and material information was obtained by the use of the solid state below the lens detector in addition to beam deceleration.

It is a apatite coating on the titanium alloy formed using a biomimetic method. The ceramic is Chrysanthemum like: the central dense mineral looks like pistil and the oriented mineral planes looks like petals.

Image obtained during the examination of an automotive light bulb to determine the cause of premature rupture of the filament. It shows a layer of iron oxide, involving a tungsten filament. At the bottom, the presence of liquid phase indicates that there was overheating due to short circuit.

Twinning defects in Bilayer (flower) and Trilayer (hexagon, bottom) Oriented graphene sheets are revealed by contrast changes in this series of Warhal-inspired Dark-Field TEM images. Strain induced Moire patterns (hexagon, top) are caused by a small lattice mismatch in the first and third layers. The layers are colored by their thickness, and each of the six images correspond to a different diffraction peak, providing unique information regarding the nature of these defects.

PLGA (poly lactic-co-glycolic acid) is a biodegradable and biocompatible copolymer that is widely used in the pharmaceutical industry as a drug delivery vehicle.PLGA microspheres were attached to a SEM stub with a carbon adhesive disc and being transferred using a squirrel hair brush. Excess sample was removed with a gentle spray of compressed air and then placed into the FEI Quanta FEG 200 for imaging. To enhance surface morphology of the spheres, a low accelerating voltage of 2KV was selected to be the optimum for this kind of sample with a chamber pressure of 180 Pascal’s. A digital image was captured, imported into photoshop and coloured by Steve Gschmeissner.

False-colored SEM image of the parasite Trypanosoma brucei gambiense (15 micrometers long) responsible for human sleeping sickness in Western and Central Africa. Human innate immunity is overpowered by this parasite through a mechanism that we have discovered in our laboratory. We have dedicated the past two decades to study the molecular arms race between humans and trypanosomes and discovered the importance of resistance to these parasites in human evolution.

The black plague is caused by the pathogen, Yersinia pestis. It only takes one Yersinia bacterium to cause an infection, which is deadly if not treated promptly. Immune cells (macrophages - purple/teal) were infected with Yersinia pestis (bright green), fixed, critically point dried, sputter coated with platinum, and imaged.

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.
