Die Informationsbroschüre „Elektromobilität in einer vernetzten Welt“ richtet sich an IT-Dienstleister. In dieser Broschüre werden mögliche Potenziale im Bereich der Elektromobilität aufgezeigt. Die Mobilität der Zukunft ist eine interdisziplinäre Angelegenheit und kein reines Automotive-Thema mehr. Beispiele wie Mobilitätsmanagement, eCommerce und Individualisierung sind im Mobilitätsbereich für die IT-Branche relevant.
As researchers continue to seek the expansion of the material base for additive manufacturing, there is a need to focus attention on the Ni–Cu group of alloys which conventionally has wide industrial applications. In this work, the G-NiCu30Nb casting alloy, a variant of the Monel family of alloys with Nb and high Si content is, for the first time, processed via the laser powder bed fusion process (LPBF). Being novel to the LPBF processes, optimum LPBF parameters were determined, and hardness and tensile tests were performed in as-built conditions and after heat treatment at 1000 °C. Microstructures of the as-cast and the as-built condition were compared. Highly dense samples (99.8% density) were achieved after varying hatch distance (80 µm and 140 µm) with scanning speed (550 mm/s–1500 mm/s). There was no significant difference in microhardness between varied hatch distance print sets. Microhardness of the as-built condition (247 HV0.2) exceeded the as-cast microhardness (179 HV0.2.). Tensile specimens built in vertical (V) and horizontal (H) orientations revealed degrees of anisotropy and were superior to conventionally reported figures. Post heat treatment increased ductility from 20% to 31% (V), as well as from 16% to 25% (H), while ultimate tensile strength (UTS) and yield strength (YS) were considerably reduced.

A concept for a sensitive micro total analysis system for high throughput fluorescence imaging
(2006)
This paper discusses possible methods for on-chip fluorescent imaging for integrated bio-sensors. The integration of optical and electro-optical accessories, according to suggested methods, can improve the performance of fluorescence imaging. It can boost the signal to background ratio by a few orders of magnitudes in comparison to conventional discrete setups. The methods that are present in this paper are oriented towards building reproducible arrays for high-throughput micro total analysis systems (µTAS). The first method relates to side illumination of the fluorescent material placed into microcompartments of the lab-on-chip. Its significance is in high utilization of excitation energy for low concentration of fluorescent material. The utilization of a transparent µLED chip, for the second method, allows the placement of the excitation light sources on the same optical axis with emission detector, such that the excitation and emission rays are directed controversly. The third method presents a spatial filtering of the excitation background.
Magnetic detection structure for Lab-on-Chip applications based on the frequency mixing technique
(2018)
A magnetic frequency mixing technique with a set of miniaturized planar coils was investigated for use with a completely integrated Lab-on-Chip (LoC) pathogen sensing system. The system allows the detection and quantification of superparamagnetic beads. Additionally, in terms of magnetic nanoparticle characterization ability, the system can be used for immunoassays using the beads as markers. Analytical calculations and simulations for both excitation and pick-up coils are presented; the goal was to investigate the miniaturization of simple and cost-effective planar spiral coils. Following these calculations, a Printed Circuit Board (PCB) prototype was designed, manufactured, and tested for limit of detection, linear response, and validation of theoretical concepts. Using the magnetic frequency mixing technique, a limit of detection of 15 µg/mL of 20 nm core-sized nanoparticles was achieved without any shielding.
Wohlfühlen in den eigenen vier Wänden : ein Produkt, welches die Wohn- und Lebensqualität steigert.
(2023)
Viele Menschen fühlen sich in ihren eigenen vier Wänden nicht wohl. Sie sind gestresst und können nicht entspannen. Ziel dieser Arbeit ist es, ein Produkt zu erschaffen, welches in seinen Funktionen und seinem Design dafür sorgt, dass die Nutzer:innen sich zu Hause wohler fühlen. Es soll alle Funktionen vereinen, die dafür sorgen, dass der Alltagsstress besser bewältigt werden kann und man in seinem Zuhause entspannen kann und den Moment mehr genießt. Entstanden ist Iwa, ein Produkt, welches zum einen als Luftreiniger arbeitet und die Raumluft filtert und im Zusammenspiel mit Licht und Musik die Raumatmosphäre verbessert und so Stress mindert. Das Design soll genau wie die Funktionen beruhigend, entspannend und erdend wirken. Es ist angelehnt am Zen-Design. So bietet Iwa einen großen Mehrwert. Die Funktionen sorgen im Zusammenspiel mit dem Design für eine verbesserte Wohn- und Lebensqualität.
