Separation of polydisperse, single-charged analytes in the nanometer size range in a high laminar sheath flow of particle-free ambient air and a tunable electric field based on the respective particle electrophoretic mobility diameter (EMD) can be ac

Low amounts of oxygen in AlCrN hard coatings have been quantitatively analysed by means of WDS–EPMA. By combination with SIMS depth profiling, applying a calibration sample produced by ion implantation, the accuracy of the EPMA results was proven.

In 1998, in the Coin Cabinet of the Kunsthistorisches Museum, Vienna, Austria, brown spot corrosion was detected on about 400 gold coins and medals minted in Central Europe between the late 18th and early 20th century. The cause of the brown spots, t

In the last decade ion implantation of common dopants in silicon has been almost full characterised. However, data of inner transition elements are based on few measurements or even extrapolations. Our investigations focus on erbium, an upcoming dopa

In order to establish a new handling procedure for contaminated coins, the Coin Cabinet and the Conservation Science Department of the Kunsthistorisches Museum, Vienna, initiated a research project on corrosion effects of gold coins. By now, investig

Coupled binary collision and kinetic lattice Monte Carlo simulations are used to analyze 30 keV B channeling profile measurements of damage from 30 keV N implants in (1 1 0)-Si. Collision cascades are generated in the binary collision approach, while

Several homogeneous carbon-boronitride (BCN) coatings were produced with cold-wall chemical vapor deposition varying the temperature of the deposition substrate from 800 °C up to 1400 °C. The deposition temperature has an influence on the growth ra

Refractory metal alloys play an important role as highly thermostable materials in the air- and spacecraft industry. Due to their lack of oxidation stability at elevated temperatures it is necessary to protect them with coatings. The thermal-cycle-st

The distribution of the relevant elements within TiN coatings, made with two different physical deposition methods as the conventional dc vacuum arc method and the filtered high current pulsed arc method (-HCA) are characterized and finally compared.

Silicon- and aluminium oxynitride films have gained attention because of their interesting properties in various fields of technology. The specific properties strongly depend on the concentration of oxygen and nitrogen in the films. For the quantitat
