Energy Technologies and Environmental Impact

• Energy technologies simulation-assessment (hydrocarbons recovery, porous membranes)
• Gas storage in solid materials (CO2, H2)
• Underground reservoir simulation and characterization
• Safety assessment for hydrogen and toxic gas installations
• Characterization of and Transport in Porous and Composite Media : Characterization of a wide range of nanostructured materials for environmental, energy and industrial processing applications with emphasis on inorganic and hybrid porous media.
• Environmental impact studies (private and public sectors)

Computational modelling in the areas of meteorology, atmospheric pollution, emergency response, safety and security

• Simulations of atmospheric dispersion & transformation of pollutants (Hysplit, WRF, CMAQ & in house models)
• Data assimilation of measurements in atmospheric dispersion models to improve the quality of prognoses and to evaluate the unknown or uncertain rate of emission of pollutants from a source; source apportionment of particulate matter indoors to identify and characterize sources by combining measurements and statistical methods; inverse modelling for air quality to evaluate the influence of air pollution sources on pollution levels and the inter-dependency between reacting pollutants
• Computational modelling activities for the evaluation of exposure to hazardous atmospheric pollutants, both outdoors and indoors, and in the area of large eddy simulation of complex turbulent flows
• RODOS Decision Support System for Nuclear Emergencies,  National Nuclear and Radiological Emergency Response Plan
• Environmental Consulting Studies to Industries and Authorities on Environmental Problems, Software for Environmental Impact Assessment of atmospheric pollutants

Measurements & Chemical analysis of environmental pollutants

• Indoor & Outdoor Air quality Measurements on all scales from personal exposure to regional assessment :
  • Airborne Particulate Matter (TSP, PM10, PM2.5 and PM1) measurements with low and high volume samplers.
  • Volatile Organic Compounds (n-alkanes, aromatic H/C, aldehydes and ketones, sulfur compounds etc) sampling and analysis in indoor, outdoor and occupational environment.
  • Chemical analysis of particulate matter for the detection of OC/EC, ions and PAHs and cross-correlation with atmospheric pollution indicators in order to estimate their origin.
  • Inorganic compounds measurements (NOX, SO2, O3, CO) in indoor, outdoor and occupational environment
  • Isokinetic stack sampling for the determination of air pollutants emissions from industries
  • Meteorological measurements (WS, WD, T, RH) in order to investigate the role of meteorology to the recorded air pollutants’ values.
  • Particle counts up to very high concentrations (particles/litre) and dust mass distribution in different size ranges in order to relate the results with health symptoms of the people living or working in a building
  • PM personal cloud measurements with portable, small and unobstructive exposure sampling devices.
• Chemical characterization of aerosols and atmospheric samples for the detection of VOCs, OC/EC, Ions & Inorganic compounds
• Identification of air pollution sources and quantitative assessment of their contribution through PM chemical analysis and Receptor Modelling Application (e.g Positive Matrix Factorization, Chemical Mass Balance)
• Industrial Plume Tracking and vehicle emission measurements. Collaboration with industry, government agencies and local authorities to identify air quality problems, perform comprehensive chemical analysis and suggest solutions.
• Fully equipped laboratory for chemical analysis with high sensitivity devices (GC/FID with Thermal Desorption Unit, GC/FPD, GC/MS/ECD, HPLC, IC, OC/EC analyzer, TEOM).
