Dissolution of UO2, U3O8, and solid solutions of actinides in UO2 in subacid aqueous solutions (pH 0.9-1.4) of Fe(III) nitrate was studied. Complete dissolution of the oxides is attained at a molar ratio of ferric nitrate to uranium of 1.6. During this process actinides pass into the solution in the form of U(VI), Np(V), Pu(III), and Am(III). In the solutions obtained U(VI) is stable both at ro...

Given our vast methane reserves and the difficulty in transporting methane without substantial leaks, the conversion of methane directly into electricity would be beneficial. Microbial fuel cells harness electrical power from a wide variety of substrates through biological means; however, the greenhouse gas methane has not been used with much success previously as a substrate in microbial fuel ...

In a dual-fuel (DF) combustion process, the ignition of main fuel plays crucial role on engine performance and emissions. present work, pilot is used to ignite gaseous methane-air mixture. Three diesel-like fuels are comparing especially cetane number (CN) aromatic content (AC). The experiments conducted in single-cylinder heavy-duty research keeping total-fuel energy constant. Lean conditions ...

alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...

In this chapter, the physical properties of group III-nitride compound semiconductors are reviewed in the context to act as semiconducting material in photoelectrocatalytic solar fuel structures. The band alignments in the InN-GaN-AlN-InN alloy system are summarized and discuss with respect to potential catalysts HOMO and LUMO states, providing efficient charge transfer in photoelectrochemical ...

A simple and rapid method with low radiation exposure risk was developed for the determination of neodymium in spent nuclear fuel by capillary electrophoresis with laser-induced fluorescence detection using a fluorescent probe having a macrocyclic hexadentate polyaminocarboxylate structure. The concentration of Nd(III) in a spent nuclear fuel sample was determined with no interference from vari...
