A new type of bioelectrochemical system for producing electrical power, called a microbial reverse-electrodialysis cell (MRC), was developed to increase voltages and power densities compared to those generated individually by microbial fuel cells (MFCs) or reverse electrodialysis (RED) systems. In RED systems, electrode overpotentials create significant energy losses due to thermodynamically un...

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...

By-products and surpluses from food industries could generate peptides with great interest for food formulation. Hence, the separation and concentration of bioactive peptides from natural sources becomes increasingly attractive to the food industry [1]. Recently, a snow crab byproducts hydrolysate showed antibacterial activity [2]. This activity was due to an antibacterial peptide of about 800 ...

Since the discovery of perchlorate in the ground and surface waters of several western states, there has been increasing interest in the health effects resulting from chronic exposure to low (parts per billion [ppb]) levels. With this concern has come a need to investigate technologies that might be used to remediate contaminated sites or to treat contaminated water to make it safe for drinking...

Combining two solutions of different composition releases the Gibbs free energy of mixing. By using engineered processes to control the mixing, chemical energy stored in salinity gradients can be harnessed for useful work. In this critical review, we present an overview of the current progress in salinity gradient power generation, discuss the prospects and challenges of the foremost technologi...
