METHODS FOR THE REALIZATION OF RADIOACTIVE STANDARDS AND FOR THE ENVIRONMENTAL RADIOACTIVITY MEASUREMENT

The radionuclide metrology assures: the realization, the conservation and the transmission of the “activity” standards, in various fields of measurement, environmental radioactivity characterization being included. The R...

 

THE MONITORING OF 2D-3D TRANSITION FOR InAs/GaAs (001) SELF-ASSEMBLED QUANTUM DOTS BY ATOMIC FORCE MICROSCOPY

We present a detailed Atomic Force Microscopy study of InAs/GaAs (001) selfassembled quantum dots grown by Molecular Beam Epitaxy during its complete evolution cycle (transition from 2D islands to 3D islands). We have pe...

ENVIRONMENTAL RESEARCHES - A WAY OF GUIDING HIGH SCHOOL STUDENTS TO SCIENTIFIC RESEARCH

An air quality study using lichens as biomonitors was done by involving of high school students. After a detailed describing of every stage of the research and their personal studies, they have participated on the select...

NEUTRON ACTIVATION METHOD APPLIED IN THE STUDY OF TRANSFER EFFICIENCIES OF MINOR ELEMENTS DURING STEELMAKING

Neutron activation analysis was applied to investigate the behaviour of some metallurgical materials (pig iron, scrap, lime, LD steel, refining slag, sludge, ferroalloys, aluminum, coke, deoxidized steel, final slag) inv...
