Theoretical and experimental investigation of performance characteristics and design aspects of cross-spring pivots. - In: International journal of solids and structures, Bd. 185/186 (2020), S. 240-256
Cross-spring pivots have been widely employed over the last decades in a broad variety of precision engineering applications due to the high motion repeatability achieved thanks to the absence of stick slip and clearance. In this paper, the non-linear effect of the anticlastic curvature of the leaf-springs is considered for the accurate analytical modeling of the elasto-kinematic behavior of cross-spring pivots. Finite element analyses (FEA), based on a non-linear thin-shell model, are carried out in order to compare them with the analytical results for the main performance parameters of this type of device, i.e. center-shift, rotational stiffness and stress in the leaf-springs. Furthermore, an experimental setup is built to assess the applicability limits of both models. Finally, remarkable performance aspects of cross-spring pivots are discussed aiming for design improvements.

Nanopositioning and nanomeasuring machines. - In: Metrology, (2019), S. 35-58
Continuing engineering progress in precision fabrication technologies, especially in the semiconductor industry, precision optics fabrication, and the diversified micro- and nanotechnologies, stimulates the advance in precision metrology. Fabricated structures reach atomic dimensions in ever-larger areas, thus becoming more and more complex, also in three dimensions. Consequently, measurements are made - to an increasing extent - of larger surface regions and sidewalls with higher aspect ratios as well as fully 3D micro- and nanostructures. Advanced high precision measurement technology is more and more an enabling technology for nanotechnologies. Today, nanopositioning and nanomeasuring machines provide high-precision measurements and the positioning of objects across different scales, from subnanometers up to several centimeters. This chapter deals with the requirements for highest measurement performance at the limits of physics and technology, resulting from the progress and the goals of modern high-tech fabrication technologies. The fundamentals of the nanopositioning and nanomeasuring machine, developed at the Institute of Process Measurement and Sensor Technology of the Ilmenau University of Technology and manufactured by the SIOS Meßtechnik GmbH Ilmenau, are described, and the measurement capabilities, potential applications, progress in research, and prospects of the device for the near future are pointed out.
Electroerosion dispersion, sorption and coagulation for complex water purification: electroerosion waste recycling and manufacturing of metal, oxide and alloy nanopowders. - In: Nanotechnology perceptions, ISSN 2235-2074, Bd. 15 (2019), 1, S. 48-57
The application of EEDSC - electroerosion dispersion, sorption and coagulation (using in situ dispersion in plasma of aluminium or iron) - allowed efficient water purification from heavy metal ions and radioactive alkali ions (of Fe, Cr, Cu, Mo, Zn, Co, Ni, Cd, Mn, As, Sn, Pb, Al, Ba, Co, Cs and Sr) as well as from organic contamination. Intensive ozonization should be applied because of intensive foam formation as a result of complex electrohydrodynamic effects during removal of the "heavy" organic contaminants (such as from liquid waste from landfills) during EEDSC. The method of electroerosion dispersion is very effective for the production of nano and submicron powders (5 nm-3 [my]m) of metals, oxides, nitrides and carbides as well as for recycling of any conductive materials such as cemented carbides, alloys of heavy metals, metallic waste products etc. The iron oxide polyvalent magnetic nanoparticles produced by electroerosion dispersion attract considerable interest in many fields of research and application. They have high potential for applications in the field of biomedical sciences (diagnostics and therapy), ferrofluids, catalysis, coloured pigments, high-density magnetic recording, printer toners, Li-ion batteries, wastewater treatment and absorption of electromagnetic waves.
