Trabecular Rete of Human Oculus

The trabecular rete of human oculus consists of crossing collagen fibers with cells and extracellular matrix on the surface. Also on the surface of the trabeculae we can see round granules (not bacteria) of organic origin. The use of SEM in ophthalmologic microsurgery allows to evaluate the quality of surgical technique. These studies were conducted jointly with Lyubimova T.S. from Scientific Technical Complex “Microsurgery of oculus”.

African trypanosome

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.

Gallium Phosphide

Pyramidal shape (ice cream like) of a GaP nanocolumn tipped by a spherical ball containing Ga + In metallic liquid. The metallic ball is coverd by a carbon nanomembrane. The structure was grown by the Metallorganic Chemical Vapours Phase Technique. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.

Lighting up the World

Incandescent light bulbs are very inefficient in transforming energy into light. Since about 20% of the world’s total electricity consumption is used for lighting, a new and more efficient light source has to be developed. One solution is solid-state lighting, which employs light-emitting diodes (LEDs) made from semiconducting materials. The image shows the cathodoluminescence (CL) from an LED excited by the electron beam of an FEI Quanta 250. CL imaging helps to understand the properties of these LEDs and gives valuable insight into prevalent defects, such as the ring-shaped defect in the image, in order to improve the devices.
