We describe experimental and theoretical results that demonstrate the feasibility of power generation using concentration cells based on ionic concentration gradients and reverse electrodialysis. A peak power density of 0.2 (0.7) lW cm 2 and a maximum energy density of 0.4 (0.4) mJ cm 3 delivered in 3 h to a 2 (5) kX resistor were recorded using a microfiltration (anion exchange) membrane, resp...

14 The removal of the trace inorganic contaminants boron (B(OH)4 ), fluoride (F ) and nitrate (NO3 ) 15 from synthetic aqueous solutions containing organic matter using electrodialysis was investigated. 16 The transport of the contaminants through the ion-exchange membranes was evaluated in relation 17 to hydrated ionic radius, whereby a positive correlation was found in absence of organic matt...

One-step purification and desalination The of water for drinking purposes can require multiple filtration steps technologies to remove contaminants such as salts heavy metals. Some could have value if recovered, but these are often discharged in the waste streams. Uliana et al. describe a general approach fabrication robust, tunable, adsorptive membranes through incorporation porous aromatic fr...

The problem as to whether or not the globulin fractions obtained from blood serum are chemical entities has been the subject of much discussion recently. Svedberg (l), basing his views on particle (molecular) weight determination, came to the conclusion that there is only one serum globulin, the molecular weight of which he determined to be 103,800. Sorensen (2) concluded, however, from solubil...
