The transmission performances of pure- and doped-silica (a-SiO2) optical fibres are compared during the exposure to a high-power broadband light source approximating the solar spectrum. From the Gaussian decomposition of the attenuation spectra, we found that Al- and P-doped fibres show a fast solarisation effect which leads to transmission degrada...
The direct dissolution and joint spinning of cellulose and lignin from NMMO-water were investigated by using dissolving pulp and purified KRAFT lignin. Compared to the rather narrow dissolution window of cellulose in the NMMO-water system, lignin with concentrations up to 15 wt.-% was shown to dissolve in a range from 30 % NMMO to 70 % NMMO at room...
Superimposing virtual visual information within the real world is referred to as augmented reality (AR). This technique becomes increasingly popular and due to technical advances can be applied to various purposes ranging from consumer entertainment to industrial use cases. Workplaces equipped with AR assistance-systems promise fast and accurate pe...
Several vaccines are already produced using the baculovirus expression vector system (BEVS). This chapter describes methods for generating recombinant baculoviral DNA (also called bacmid) for cultivating Spodoptera frugiperda Sf-9 cells and producing a baculovirus stock from the recombinant bacmid and for producing a protein-based vaccine with the ...
Heutige Methoden der Programmierung von Produktionsmaschinen erfordern großen manuellen Aufwand. Dies hat zur Konsequenz, dass der Einsatz heutiger Automatisierungslösungen nur bei großen Stückzahlen wirtschaftlich ist. Im Zuge der Massenpersonalisierung kommt es gleichzeitig zu immer höheren Anforderungen an die Flexibilität der Produktion. Damit ...
Nowadays, functionalized surfaces become more and more important for industrial applications concerning wettability, ice-repellency, self-cleaning, or tribology. In this contribution, an innovative approach is presented using the direct laser interference patterning (DLIP) technique for tailoring the wettability of copper surfaces. The interference...
Hypervelocity collisions are predicted to be the dominant space debris source in the mid-term future, when a critical spatial density of satellites is reached. The NASA Standard Satellite Breakup Model (SSBM) has been adopted by major space agencies for characterizing hypervelocity spacecraft breakups for debris environment modeling. The SSBM is an...
We study rectangular Vandermonde matrices V with N+1 rows and s irregularly spaced nodes on the unit circle, in cases where some of the nodes are “clustered” together - the elements inside each cluster being separated by at most [Formula presented], and the clusters being separated from each other by at least [Formula presented]. We show that any p...
Microstructure, mechanical performances at elevated temperature (650 °C) and their correlation of Inconel 718 manufactured by Selective Laser Melting (SLM) were investigated in this paper. Four kinds of heat treatment schemes including homogenization, solution treatment and conventional aging process were carried out to regulate the microstructure ...
