The present study examines the role of humic acid, as a representative of dissolved organic matter, in Cd(II), Cu(II) and Pb(II) speciation and biouptake by green microalgae. Cellular and intracellular metal fractions were compared in the presence of citri ...
This paper reports on medium term tests of anode-supported five-cell short stacks, as well as on some separate anode development. Two stacks were operated under steady-state conditions: one with unprotected metal interconnects, H2 fuel and 0.35Acm−2 (40% f ...
Hydrogen prodn. using earth abundant metals is one of the important challenges facing an energy economy based upon solar fuels. Schemes that incorporate the photo-oxidn. of water must also include schemes for efficiently converting released protons and ele ...

Ozonation of natural surface water increases the concentration of oxygen-containing low molecular weight compounds. Many of these compounds support microbiological growth and as such are termed assimilable organic carbon (AOC). Phytoplankton can contribute ...
It is recognized that dissolved organic matter (DOM) plays an utmost role in aquatic ecosystems by binding trace metals and influencing their speciation, bioavailability and detrimental effects. DOM is considered to protect the aquatic microorganisms from ...
In order to better understand the relationship between lead speciation and its bioavailability in natural waters, the interactions between Pb(II), fulvic acid and the freshwater alga, Chlorella kesslerii were studied at different algal cell densities. An i ...
Among renewable energy sources biomass plays a major role. Several paths for improving the conversion of biomass with minimum burden on the environment are being pursued worldwide. This paper reviews some of the most recent results from research at the Swi ...
We present a SOFC stack technology based on the unique SOFConnex™ concept. It uses flexible gas distribution layers between metal sheet interconnects and thin ASE cells (Ni-YSZ anode supported, thin electrolyte). Flexibility is given both in material and d ...
The current work examines the effects of model allochtonous (humic substances) and autochtonous (microbial polysac charides) natural organic matter (NOM) on Pb speciation and bioaccumulation. The results demonstrated that polysaccharides, in particular alg ...
