The research that began in 1958 covered the following topics:
- Diffusion and self-diffusion by means of tracer methods
- Measurement of soft ß-emitters by liquid scintillators
- The study of water migration in soils with special respect to radioactive environmental contamination
- In connection with the Chernobil accident, examination of 14C content of wines of different ages and origins
- Chemical structure research with the aid of nuclear techniques started at the end of the 1960's.
- Mössbauer spectroscopy began in 1967,
- positron annihilation spectroscopy in 1969 and
- meson chemistry in 1979.
These nuclear methods were first introduced into chemical research in Hungary at ELTE. These techniques as well as
have been applied at the Department in the following fields:
- Study of the chemical structure of solutions on the basis of the Mössbauer spectra of frozen solutions.
- Mössbauer studies in surface chemistry including the study of the chemical, magnetic, and crystal structure of electrodeposits, of surfaces of electrodes, of interphases between substrates and coatings (metal-metal, metal-organic coatings, etc.), of corroded surfaces and of ion implanted surfaces.
- Investigation of the electronic and geometric structure of coordination compounds.
Mössbauer spectroscopy of crystalline and amorphous iron alloys.
- Identification of the chemical and crystal position of the Mössbauer active nuclides in aluminum alloys containing iron and tin impurities. (The HAS acknowledged the results of these studies with a prize in 1986.)
- The Mössbauer effect was also applied to solve several industrial problems resulting in a number of industrial projects and some income for the University.
- Study of high Tc superconductors.
- Study of compounds containing buckminster-fullerenes and Mössbauer-active atoms.
- Study of the defect structure of metals and electrodeposits on the basis of the lifetime spectra of positrons.
- Positron annihilation study of the phase transformation and structure of organic polymers and polymer layers.
- Study of the surface of catalysts by the lifetime of the positronium formed in the free volume and on the surface of catalysts.
- Positronium chemistry in liquids.
- Positronium chemistry in solids.
- Study of hydrogen bonding with the aid of pi-mesons.
- Structure investigation and phase analysis of metals, alloys and compounds.
- Structure determination and identification of probes used for positron annihilation and Mössbauer studies.
