Material and Environmental Isotope Geochemistry Project has been developed in both Stable and Radiocarbon isotopes in order to conduct basic and applied research in the scientific field of Isotopic Geochemistry, focusing on material science, environmental evolution and cultural heritage. In more detail:

The Stable Isotope Laboratory (SIL), of the Institute of Nanoscience and Nanotechnology, National Center for Scientific Research Demokritos, accredited according to EN ISO/IEC 17025:2005 (no 579). In SIL, the isotopic measurements include the stable isotopes of inorganic

1. carbonate materials (δ¹³C, δ¹⁸Ο), organic materials (δ¹³C, δ¹⁵Ν), water (δ¹⁸Ο, δ²Η, δ¹¹B), sulfates (δ³⁴S), as well as elemental analysis of C, N and S in geological, biological, composite and natural materials.
2. Radiocarbon Laboratory, which is under construction however available in early 2016, is fully equipped with Liquid Scintillation Counting (LSC) and Gas Proportional Counting (GPC) analytical techniques for radiocarbon analysis (¹⁴C) as well as the required lines for sample (archaeological and modern materials) preparation. The combined use of radiocarbon and stable isotope systems for highlighting ancient and modern environments is further enhanced by radiogenic isotopes of ⁸⁷Sr/⁸⁶Sr, ¹⁴³Nd/¹⁴⁴Nd, ²⁰⁶Pb/²⁰⁷

These analytical techniques support our research work which is centered in tracing analysis for the origin of raw materials (glass, mortar), paleoecological reconstruction (bones, teeth, speleothems, soil drilling) and the authenticity/fingerprint of food industry products (wine, milk, oil, honey, cereals, etc.). The research is centered in the following scientific areas:

• Provenance determination and weathering of ancient and modern materials
• Paleoenvironmental and paleoclimatic reconstruction
• Depositional conditions of carbonate materials
• Hydrogeochemical processes in open and close system
• Origin of geofluids-pollution, palaeohydrology
• Characterization and investigation of the technology of ancient –historic structural materials (marbles, glass and mortars)
• Isotope data repositories (isoscapes, human-isobanks, food-isobanks, plants-isobanks)
• Bioarchaeology: palaeodiet and palaeomobility
• Provenance of raw materials
• Isotope fingerprint and natural genetic index (DNA)
  

• Damage diagnosis and scientific determination of weathering and decay mechanisms of ancient-historic materials and development of conservation materials.
• Radiocarbon analysis in archaeological and environmental material
• Authenticity and fingerprinting of food and products
