A fly agaric (Amanita muscaria) produces an organic molecule, which extracts vanadium from the soils and enriches it in remarkable concentrations in the mushroom.
Melting ice represents a two-phase system. The energetical situation in such systems can be explained and quantified by the laws of chemical thermodynamics.
The right choice of suitable detectors is a basic requirement for a correct quantitative determination of ionizing radiation.
Haemoglobin is a protein, which is contained in our red blood cells. The iron-containing haem molecules inside bind and transport elemental oxygen.
No all facts of chemistry can be taught by e-learning materials. The daily work in the laboratory is an important component during the education of chemistry students.
Handling of open radioactive samples requires a high level of concentration and care. Laboratory courses in radiochemistry provided the corresponding knowledge and skills.
Chlorophyll is a molecule, which is contained in photosystems of bacteria and green plants, where light energy is transferred into chemical energy.
Spider silk is a highly elastic and tearproof proteinaceous material. The building blocks of such polymers are introduced by the questions about organic chemistry.
The metastable technetium nuclide 99m-Tc is the work-horse in nuclearmedical diagnostics. It dominates single-photon computer tomography (SPECT) studies.
