In this paper, we present results on the removal of several critical contaminations from water by plasma processes. Several different plasmas were applied, differing e.g. in the gas composition, in order to identify the most promising routes for specific contaminations.

Mycoplasma contaminations have a multitude of effects on the cultured cell lines that may influence the results of experiments or pollute bioactive substances used in human medicine. The elimination of mycoplasma contaminations of cell cultures has become a practical alternative to discarding and reestablishing important or irreplaceable cell lines. Different quinolones, tetracyclines, and pleu...

Despite continued advances in whole genome sequencing techniques and the development of powerful assembly algorithms, newly sequenced genomes still often suffer from contaminations during the sequencing process. The most common sources of contamination are accessory DNAs deliberately attached to the DNA/RNA under investigation, including vectors, adapters, linkers and PCR primers. However, ther...

We propose in this paper a method for studying contact structures in 3manifolds by means of branched surfaces. We explain what it means for a contact structure to be carried by a branched surface embedded in a 3-manifold. To make the transition from contact structures to branched surfaces, we first define auxiliary objects called σ-confoliations and pure contaminations, both generalizing contac...

In this paper we investigate the surface chemistry, including surface contaminations, of SnO2 nanowires deposited on Ag-covered Si substrate by vapor phase deposition (VPD), thanks to x-ray photoelectron spectroscopy (XPS) in combination with thermal desorption spectroscopy (TDS). Air-exposed SnO2 nanowires are slightly non-stoichiometric, and a huge amount of C contaminations is observed at th...

In the course of classical optics manufacturing glass components are in permanent direct contact with aqueous operating materials. Such leads to a certain absorption water and hydrogenous compounds that may induce severe defects. this contribution, hydrogen other contaminants during grinding was observed qualitatively detected via laser-induced breakdown spectroscopy. It is shown hydrogen, calc...

Two-step PCR procedures are an efficient and well established way to generate amplicon libraries for NGS sequencing. However, there is a high risk of cross-contamination by carry-over of amplicons from first to second amplification rounds, potentially leading to severe misinterpretation of results. Here we describe a new method able to prevent and/or to identify carry-over contaminations by int...
