Electric Blue Leather Keyring
€16,99
- Polycrystalline silicon solar cell. This photovoltaic cell converts light into electrical energy, and is a clean, renewable source of energy. The cell is made from a semiconducting silicon nitride wafer (blue), covered by a grid of electrodes (white), made of silver nanoparticles, which collect the electrical current generated by the wafer. Polycrystalline (multiple crystal) cells are less efficient than monocrystalline (single crystal) cells, but are far cheaper to manufacture. Imaged with light microscopy

Phantasia Leather Keyring

- Scales on the wing of a butterfly. The color of a butterfly wing comes either from a pigment contained in the scales or from iridescence as light is diffracted by the microscopic structure of the scales themselves. The image was made using scanning electron microscopy (SEM), where a beam of electrons aimed at the surface of the material causes the generation of various signals, which are then collected to form an image

- Cross-sectional view of multiple single-celled organisms called Paramecium - a type of protozoa that is commonly found in aquatic environments, including freshwater and marine environments, as well as stagnant ponds. Some species are widely used in classrooms and labs to study single-cell biological processes, as they are easy to cultivate. The image was made using transmission electron microscopy (TEM). High-energy electrons are passed through a thin section of material and collected on the other side to form an image. Colors added later, to help visualize different features

Tangerine Dream Leather Keyring

- Atoms on the surface of a metal, in the style of Aboriginal art. This highly creative and unique design was made in several steps. First, the material was imaged using field ion microscopy, which shows the arrangement of surface atoms in the form of bright spots. The black and white image was then projected onto canvas and each dot oil-painted by hand. Some artistic license was used in the interpretation. Finally, the resulting painting was turned into a digital image
