RESEARCH AREAS and ACTIVITY DOMAINS
methods for obtaining and modifying materials to improve properties: compatibility of
polymer mixtures by radio‑induced processes; radiochemical crosslinking of polymeric
materials for the production of shape‑memory products and high dimensional stability;
radio‑chemical synthesis of metallic nanoparticles with various applications; obtaining
biodegradable polymeric composites;
new methods for investigation and analysis of materials: radio thermoluminescence
(RTL), chemiluminescence (CL) or other phisico‑chemical effects; characterization
of materials by spectroscopic analysis techniques (UV‑Vis, Raman, fluorescence,
dielectric spectroscopy), gas chromatography (TCD, FID, MSC), thermal analysis
(DSC, RTL, CL);
diagnosis of polymer materials degradation and lifetime evalation under the action
of various stress factors: thermal‑, photo‑ and radio‑oxidative, climatic aging and UV
exposure, field exposure and/or combined stress factors;
waste recycling processes: recovery of techological wastes of polytretrafluoroethylene
by processing with ionizing radiations;
radio‑protection and dosimetry of ionizing radiations (development of some dosimetric
systems of type MgF2 : Mn, MgB4O7 : Sm etc.);
analysis and characterization of synthetic and natural antioxidants;
qualification of some pieces for operation in ionizing radiations environments (CNE,
CERN ‑ France, JINR – Dubna, Russia).

Services provided by the Radiochemistry and Polymeric Materials Laboratory:
• processing of polymeric materials (obtaining granules of plastics and polymeric composites);
• characterization and testing of materials:
‑ characterization of materials by thermal analysis techniques (DSC, Chemiluminescence,
Radiothermoluminescence);
‑ organic and inorganic materials characterization by Raman Spectroscopy: determining the nature
of different types of carbon (diamond, amorphous carbon, nanotubes, graphene) and their relative
proportions; quantification of the degree of defects and evaluation of the quality of graphene sheets
(determination of D/G and 2D/G ratios); evaluation of graphene sheet thickness (number of layers);
determination of inorganic oxides and their state of valence; measuring stress and crystal structure in
semiconductors and other materials;
‑ establishing the causes that lead to the degradation of polymeric materials (e.g. the appearance of
cracks, color change etc.);
‑ investigation and identification of additives in polymer samples: antioxidants, UV stabilizers, fillers etc;
‑ determination of the physico‑chemical properties of polymeric materials;
‑ “wet chemistry”: chemical resistance, solvents solubility, swelling etc.;
‑ degradation diagnosis and evaluation of the lifetime of polymeric materials under different stressors;
‑ testing and characterization of materials under conditions of accelerated aging by exposure to gamma
radiation in order to qualify them for use in ionizing radiation environments (CNE, particle accelerators);
‑ testing and characterization of materials under conditions of accelerated aging by exposure to UV and
climate factors (xenon weathering instrument ‑ Xenotest) according to different standards: Plastics
(ASTM 2565; ISO – 4892‑2, GB/T 8814), Textiles (AATC TM16‑2004; GB/T 8427; ISO 105 – B02,
B04, B06, B10), Varnishes and paints (ISO 11341; ISO 16474‑2), Car interior materials (VDA 75202);
‑ gas chromatography analyzes GC‑TCD, GC‑FID, GC‑MS: environmental analyzes: air, pesticides,
herbicides, PAH etc.; analysis of petroleum products and biofuels; chemical industry: solvents, aromatic
compounds, perfluorocarbons, sulfur compounds, light hydrocarbons etc.; pharmaceutical industry;
cosmetics industry, personal care / cleaning products; agriculture, food industry, flavors and perfumes
etc.
• Consulting services for:
‑ overcoming of some quality and performance issues associated with raw materials or manufacturing
processes;
‑ optimizing applications, quality control and finding new uses for products;
‑ improving the performance of polymeric materials by radiochemical modification / processing;
‑ technical solutions to increase the stability of polymeric materials in different environments of use.
