Bioreduction and biocrystallization of palladium by Desulfovibrio desulfuricans NCIMB 8307
The reduction of Pd(II) to Pd(0) was accelerated by using the sulfate‐reducing bacterium Desulfovibrio desulfuricans NCIMB 8307 at the expense of formate or H2 as electron donors at pH 2–7. WithExpand

Hydrogen adsorption in zeolites a, x, y and rho
Abstract We have investigated the use of zeolites as potential hydrogen storage materials. The zeolites A, X, Y and RHO, which encompass a range of different pore geometries and compositions, wereExpand

The potential of hydrogen in permanent magnet production
Abstract In this article, the application of the hydrogen decrepitation (HD) process to the production of rare earth containing permanent magnets is discussed. It is shown that the HD process can beExpand

Palladium recovery by immobilized cells of Desulfovibrio desulfuricans using hydrogen as the electron donor in a novel electrobioreactor
Desulfovibrio desulfuricans reduces Pd(II) to Pd(0) at the expense of H2. Mass transfer limits the rate under hydrogen in a static solution, while a bubble reactor was inefficient due to loss of H2.Expand

The use of hydrogen to separate and recycle neodymium–iron–boron-type magnets from electronic waste
The rare earth metals have been identified by the European Union and the United States as being at greatest supply risk of all the materials for clean energy technologies. Of particular concern areExpand
