The interaction of copper ions with peptides was investigated by electrospray mass spectrometry. Two electrospray micro-emitters were compared, the first one with a platinum electrode using a copper(II) electrolyte solution containing a peptide sample, and ...
Ab initio calcns. were used for the rational design of efficient alc. oxidn. catalysts that mimic the enzyme galactose oxidase. Different ligand substitutions were explored based on natural (copper, depicted) and alternative (rhodium) metal redox centers. ...
Most contaminated sites related to past industrial activities in Europe are adjacent to rivers and urbanized areas. These sites pose a major problem for water authorities and policy makers in terms of contaminants mobility, natural attenuation (or degradat ...
Chromatography is increasingly being used for large-scale preparative separation of precious biological components such as recombinant proteins and DNA. Several kinds of mathematical models are used to describe the liquid chromatography process. The aim of ...
Living bacteria offer an ecological and cost-effective alternative to the classical physical and chemical techniques for the treatment of environmental contaminations. Although their increasing use in toxic metal removal, systematic studies on the influenc ...
Atoms and molecules adsorbed on metals affect each other indirectly even over considerable distances. Via systematic density-functional calculations, we establish the nature and strength of such interactions, and explain for what adsorbate systems they cri ...
There is increasing concern about environmental pollution by diffuse emissions of various environmental hazards emitted by transportation activities. For the first time substances released by railways to the environment were investigated. We considered the ...
Application of a direct elec. field in contaminated soils is expected to produce an important in situ means of environmental restoration. The factors that det. the success of the process are the combined effects of electroosmosis, ionic migration, electroc ...
Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
This work demonstrates the capabilities of nanoscale secondary-ion mass spectrometry, using the Cameca NanoSIMS50 ion microprobe, to detect and image the copper-ion distribution in microalgal cells exposed to nanomolar and micromolar copper concentrations. ...
