(München : oekom verlag GmbH, 2022)
Of the three main time horizons specified in the German Repository Site Selection Act (the year 2031, 500 years after closure and one million years), the current public discourse largely neglects the “medium term”. However, ...

Denkena, B.; Liu, H.C.; Pape, F.; Bergmann, B.; Poll, G.; Schenzel, J.; Ellersiek, L.
(Amsterdam [u.a.] : Elsevier, 2023)
Cutting fluids significantly influence the contact conditions in metal cutting, e.g. stresses or contact areas. Due to the limited accessibility of the chip-tool contact, the identification of contact conditions is ...

(Dordrecht [u.a.] : Springer Science + Business Media B.V, 2023)
Vitrification could enable long-term organ preservation, but only after loading high-concentration, potentially toxic cryoprotective agents (CPAs) by perfusion. In this paper, we combine a two-compartment Krogh cylinder ...

Ince, C.-V.; Blümel, R.; Raatz, A.
(Amsterdam [u.a.] : Elsevier, 2023)
A significant percentage of energy in hot forming is used to heat the components. Especially in manufacturing hybrid components, workpieces are heated in the preceding hot-joining process in addition to the heating cycles. ...

Denkena, Berend; Bergmann, Benjamin; Picker, Tobias; Kraeft, Malte
(Amsterdam [u.a.] : Elsevier, 2023)
The wear behaviour of cutting tools can be significantly improved by a load-optimized design of the cutting edge microgeometry. Thereby, the knowledge of local mechanical stresses is necessary. The experimental-based ...

(Dordrecht [u.a.] : Springer Science + Business Media B.V, 2023)
The ability to interact safely with the environment is known as one of the major advantages of soft robots (SRs). Due to their low material stiffness, these continuously deformable robots offer inherent flexibility. These ...

(Basel : MDPI, 2023)
Due to the high specific surface area of titanium aluminide powders, significant and unavoidable surface oxidation takes place during processing. The resulting oxides disrupt the conventional powder metallurgical process ...

Wiesener, F.; Bergmann, B.; Wichmann, M.; Eden, M.; Freudenberg, T.; Schmidt, A.
(Amsterdam [u.a.] : Elsevier, 2023)
Tool grinding is a fundamental process step when manufacturing cylindrical cemented carbide tools. A deeper understanding of the relationship between heat generation, heat transfer and fluid dynamics is essential to optimize ...

Leffers, Lennart; Roth, Bernhard; Overmeyer, Ludger
(Amsterdam [u.a.] : Elsevier Science, 2023)
We analyse and evaluate the sensitivity and robustness of an eccentric fiber Bragg grating sensor micro-structured into a polymer optical fiber under different relative humidity, temperature, strain and torsion conditions. ...

Breidenstein, Bernd; Vogel, Nils
(Berlin ; Heidelberg : Springer, 2024)
Cutting tools made of the ultra-hard composites polycrystalline diamond and polycrystalline boron nitride are being used in more and more sectors of machining. Due to the laborious preparation processes such as grinding, ...

(Amsterdam [u.a.] : Elsevier, 2024)
Machinability is a generalized framework that attempts to quantify the response of a workpiece material to mechanical cutting, which has been developed as one of the key factors that drive the final selection of cutting ...

(Amsterdam [u.a.] : Elsevier, 2024)
Solid surface freezing or vitrification (SSF/SSV) can be done by depositing droplets of a sample, e.g., cells in a preservation solution, onto a pre-cooled metal surface. It is used to achieve higher cooling rates and ...

(Amsterdam [u.a.] : Elsevier Science, 2024)
The production and pollution of plastic present a significant threat to global ecosystems, where annual plastic emissions in aquatic ecosystems are projected to triple between 2020 and 2030. Currently, plastics are widely ...

Surmann, Tobias; Denkena, Berend; Friebe, Sven; Schmidt, Alfred; Adili, Maimaiti
(Düsseldorf : VDI Fachmedien, 2024)
Thin-walled structural components often tend to chatter vibrations due to their compliancy. Modal analyses can be used to calculate stability maps and avoid chatter vibrations, but this is time-consuming. ZeTeM Bremen and ...

(New York, NY : Springer, 2024)
To detect mechanical overloads on the component directly in operation, a metastable material can be used as a load-sensitive sensor when combined with an eddy current testing system. In order to find a suitable metastable ...
