Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of al ...
The zone of calcified cartilage (ZCC) is critical for the normal attachment of articular cartilage to bone as well as to the biomimetic bioengineering of osteochondral tissue constructs. However, relatively few osteochondral tissue engineering approaches h ...
In the bauxite refining Bayer’s process, about 8 x 107 t/y of problematic residue is produced worldwide by extraction of alumina from bauxite earth. The bauxite refining industry requires strategies for rehabilitation of residue deposits to comply with leg ...
Arsenic derived from natural sources occurs in groundwater in many countries, affecting the health of millions of people. The combined effects of As(V) reduction and diagenesis of iron oxide minerals on arsenic mobility are investigated in this study by co ...
The sorption of uranium on mineral surfaces can significantly influence the fate and transport of uranium contamination in soils and groundwater. The rates of uranium adsorption and desorption on a synthetic goethite have been evaluated in batch experiment ...
Chloroethenes are the most prevalent groundwater contaminants in developed countries. They accumulate in the environment as a dense non aqueous phase liquid (DNAPL) which acts as a long term source of contamination. Enhanced in situ anaerobic bioremediatio ...
Enhanced in situ bioremediation of chlorinated solvents is, especially in source zone remediation, often limited through the accompanied high acidification of groundwater. This acid built-up originating from the dechlorination itself and fermentation produ ...
Hydrolysis and hydrogenation of [RhCl(tppms)(3)] (1) and trans-[RhCl(CO)(tppms(2)] (2) was studied in aqueous solutions in a wide pH range (2 < pH < 11) in the presence of excess TPPMS (3 -diphenylphosphinyl-benzenesulfonic acid sodium salt). In acidic sol ...
Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater due to their extensive use in industrial processes. In situ bioremediation (ISB) is an attractive technology for removal of the ...
The organic interprismatic layers of the mollusc Pinctada margaritifera are Studied using a variety of highly spatially-resolved techniques to establish their composition and structure. Our results show that both the interlamellar sheets of the nacre and i ...
