The project is aimed at recovering uranium from scrap material containing useful amounts of Low Enriched Uranium. The common method of recovering uranium is by using acidic or alkaline medium for dissolution, followed ...

Nanoporous carbons which possess high surface areas and narrow pore size distributions have become one of the most important classes of porous materials with potential to be utilized for hydrogen storage. In recent times, ...

The solution copolymerizations of tetrafluoroethylene (TFE) with isobutyl vinyl ether (iBuVE), using both conventional radical and RAFT/MADIX methods, are presented. O-Ethyl-S-(1-methyloxycarbonyl)ethyl xanthate and benzoyl ...

Equilibrium and rate-based dynamic models are proposed for a laboratory-scale, fed-batch, packed distillation column that operates at sub-zero temperatures. The purpose of the column is to separate tetrafluoroethylene from ...

The sheath gas plays an important role in inductively-coupled plasmas (ICPs) in preventing thermal damage to the side wall of the torch. The sheath gas (hydrogen in our case) is more difficult to ionise than argon (the ...

PTFE homopolymer synthesised using ammonium persulfate initiator discolours at sintering temperatures of approximately 380 °C. No report on this phenomenon is available in the open literature. To shed light on the problem, ...

Isothermal vapor−liquid equilibrium data are presented for the 1,1,2,2-tetrafluoroethylene and 1,1,2,3,3,3-hexafluoroprop-1-ene binary system at (248.14, 263.01, and 282.89) K, with pressures ranging from (0.12 to ...

More than 30 percent of the global demand for zircon (ZrSiO4) is supplied by South Africa. A significant amount of the zircon is exported, and beneficiated products are then imported for industrial applications locally. ...

A microwave plasma process operating at atmospheric pressure was developed for the synthesis of SiC nanoparticles. The process utilizes methyltrichlorosilane (MTS) as precursor, acting as both carbon and silicon source, ...

The separation of tantalum and niobium compounds has been of interest for many years, with few new developments. Classically separation is achieved by liquid–liquid extraction and most research focuses on optimising this ...
