Removal of sulfur from a solvent extract
PublicationThe presence of sulfur in a solvent extract that is to be analyzed chromatographically impairs and sometimes precludes properinterpretation of the chromatogram, as the sulfur peak masks the peaks of other compounds present in the sample, and sulfur alsodisrupts the operation of the mass detector. This means that discrepancies in the results can lead to erroneous interpretations andfalse assessments of environmental risk. For this...

Broadcast copies reveal the quantumness of correlations
PublicationWe study the quantumness of bipartite correlations by proposing a quantity that combines a measure of total correlations-mutual information-with the notion of broadcast copies-i.e., generally nonfactorized copies-of bipartite states. By analyzing how our quantity increases with the number of broadcast copies, we are able to classify classical, separable, and entangled states. This motivates the definition of the broadcast regularization...

Incorporation of the sulfur cycle in sustainable nitrogen removal systems - A review
PublicationIn wastewater treatment systems, sulfur (S) removal processes are generally based on heterotrophic sulfate (SO42−) reduction by sulfate reducing bacteria and S-dependent autotrophic denitrification by sulfur oxidizing bacteria. A combination of either two cycles (N and S) or three cycles (N, S and C) appears to be a viable approach to sustainable wastewater treatment, resulting in energy savings and reduction of sludge production....
