A ternary mixed metal oxide catalyst controls emissions from combustion processes. It exhibits low temperature oxidation of pollutant species without the use of expensive platinum group metals.
This extractive metallurgy invention dissolves rare earth element containing minerals important in the United States as well as metal oxides and metal carbonates.
The present invention comprises a new sodium based electrolyte system that has an electrochemical window of 4V, which is suitable for use as electrolytes for high energy density supercapacitors.
Membrane-based dispersion-free supported liquid membrane solvent extraction (MSX) for the separation, concentration and recovery of rare earth elements such as neodymium, europium, yttrium, terbium and dysprosium enables the process to operate in a single step delivering multi
This invention targets the extraction of rare earth elements from fly ash residues. The residues are leached and the aqueous phase is then extracted using an organic phase.
This invention affords the quantitative extraction of rare earths present in phosphoric acid streams produced in phosphoric acid plants. The stream is typically 27%-30% P2O5 while the total amount of rare earths is estimated at 150-200 ppm.
A lubricant additive is an ionic liquid phosphonium salt. The phosphonium cation of the ionic liquid is in a symmetric quaternary structure ([PR4]+) having four hydrocarbyl groups with the same number (>=4) of carbon atoms.
The invention relates to testing systems and more specifically to systems for cryogenic characterization.
The present invention comprises ultrathin (<1 µm) high permselectivity carbon molecular sieve membranes (CMSM) for industrial gas separations.
The present invention comprises a new sol-gel precursor chemistry that will form flexible tin-doped indium oxide (ITO) nanofibers at diameters of 50-400nm.
