C-14 Activity concentration determination in inorganic carbon from water samples and carbonate material

The novelty lies in preparation in the laboratory, after an own recipe, of scintillation cocktail used, and the development of specific procedures for the preparation of water samples and carbonate material. These procedures follow similar principles to that using benzene synthesis method. The diffe...

Experimental stand for determination of material toughness (resilience)

The experimental stand was developed on industrial equipment made for Charpy-V measurements. The toughness (resilience) of the materials could be measured, with this experimental stand, in a wide range of temperatures, 4 K to 300 K. In order to increase the accuracy of the testing and also to simpli...

Experimental stand for studies of hydrogen isotopes permeation

The permeation experiments show an increase in the tritium permeation rate for small increases of temperature and pressure. Oxide layers at the surface usually reduce protium, deuterium or tritium permeation. Also the permeation of hydrogen through metals is influenced by trapping at internal defect...

Magnetic filter for industrial gases depollution

The basic principle of the magnetic filter is high gradient magnetic filtration (HGMF) which consists in the capture of the magnetic particles considered as impurities and having generally low concentrations from a fluid. The active part of the magnetic filter is a ferromagnetic matrix made of very...

Mathematical model for the CFD analyses of Proton Exchange Membrane Fuel Cell

The mathematical model and the CFD simulations can lead to geometry optimization (size and pattern of the fluid flow channels) and parameters optimization (properties, flow rates) for PEM fuel cells. Can help to address all the challenges that appear in the PEM fuel cell technology, followed by an i...

Method of production and soil fertilizer obtained by capture of carbon dioxide and ammonia in biochar

The use of carbon-based fertilizers to effect long-term storage of the carbon and remove atmospheric carbon dioxide. The designation of the carbon from fertilizer is a good carrier for nutrients due to its high cation exchange capacity. The carbon-based fertilizer (NH4HCO3-char) has properties tha...

Production and use of bio-char rich in nitrogen (NH4HCO3-char) as fertilizer and soil amendment

Technology and unassembling jointing system between polytetraphluoroethylene (PTFE) and metals

To joint different materials such as very resistant polymer polytetrafluoroethylene (PTFE) and metals is a challenge. The joint is achieved through particular procedure of soldering, simultaneous with plastic deformation of the metal. The bonding is achieved only after a suitably treating of PTFE su...
