“BACKGROUNDIon-exchange has been a powerful tool for metal recovery. Germanium has been recovered using the commercially available

N-methylglucamine resin. To treat waste-water from solar panel displays a method to separate selectively germanium from silicate ion was required. A novel recovery of germanium is proposed in which germanium is complexed with catechol in solution and the complex solution flowed through a membrane or bead-packed bed.

RESULTSBy changing pH, germanium was complexed with catechol, 3-methylcatechol and 4-nitrocatechol in solution and the solution was adsorbed on the membrane in a batch mode, demonstrating that catechol exhibited a high adsorption performance in neutral pH. In selleck chemicals llc a continuous system, the membrane achieved faster adsorption of the germanium complex than a bead-packed bed.

CONCLUSIONThe high-speed recovery of germanium was due to the transport to the vicinity of quaternary amino group MK-4827 ic50 in the membrane via convection. A germanium solution containing silicate ions was passed through the membrane system, resulting in highly selective recovery of germanium ion. (c) 2012 Society of Chemical Industry”

bulk polycrystalline samples with nominal compositions Mg1-x(Eu2O3)(x/2)B-2 and Mg1-x(Pr6O11)(x/6)B-2 (where x = 0.0, 0.01, 0.02, 0.03, 0.04, and 0.05) have been prepared via standard solid-state reaction route. Vorinostat The x-ray diffraction (XRD) results of both series of materials reveal the presence of secondary phases MgO and REB6(RE=Eu/Pr) besides the main hexagonal phase of MgB2. The magnetic and electrical measurements show that transition temperatures (T-c) of both Eu2O3 and Pr6O11-doped MgB2 samples decrease from 39 to 37 K when values of x increase from 0.0 to 0.05. Improvement in critical current density (J(c)) at 10 K has been observed at higher

fields (>4 T) for Eu2O3-doped samples of composition x = 0.04 and in entire field range (0-5 T) in the case of Pr6O11-doped samples of composition x = 0.03 as compared to the J(c) values of other compositions. The J(c) values at 5 T field and 10 K of undoped, x = 0.03 for Pr6O11-doped and x = 0.04 for Eu2O3-doped MgB2 samples are 2.21 x 10(3), 1.15 x 10(4), and 1.10 x 10(4) A/cm(2,) respectively. Improvement in Hc(2) and Hirr has also been observed in doped samples. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3072379]“
“OBJECTIVE

Ultrasound-guided foam sclerotherapy is increasing in popularity as a method to treat varicose veins of the lower extremities. In 2001, we began using ultrasound-guided foam sclerotherapy to treat varicose veins of the lower extremities. The outcomes of our treatment are described in this study.
