Titel: Acoustic wave lab-on-chip is now flexible, bendable and potentially wearable!

Abstract: Thin film acoustic wave devices especially surface acoustic waves (SAW) have been used for sample preparation (sorting, separating, mixing, nebulization and dispensing) as well as bio-sensing. This talk will focus on our recent work of flexible and wearable thin film acoustic wave lab-on-chip (mainly using ZnO and AlN films on flexible substrates) for acoustic wave based microfluidic applications. We report theoretical and experimental studies of the evolution, hybridization and decoupling of wave modes in the flexible acoustic wave devices, as well as their vibration patterns. thus providing a guide for different microfluidic applications. Thin film based flexible SAW devices have the potential to be integrated with other microfluidic and sensing technology on flexible substrates including CMOS integrated circuits to make novel lab-on-chip for bio-detection for wearable and flexible applications. SAW devices on commercial polymer and aluminum foils have been fabricated and various microfluidic functions, such as mixing, pumping, jetting have been demonstrated with bent and deformed acoustic wave devices.

Titel:  „Datenschutz: Anbruch eines neuen Zeitalters? – Zur Geltung der EU-Datenschutzgrundverordnung ab dem 25. Mai"

Abstract: Ab dem 25.5.2018 haben alle Bürger, Behörden und Unternehmen neue Vorschriften zum Datenschutz zu beachten, denn dann gelten europaweit die Regelungen der „EU-Datenschutzgrundverordnung“ sowie in Deutschland ein Bundesdatenschutzgesetz, bei dem nicht ein einziger Paragraph so wie vorher geblieben ist. Darauf weisen seit Monaten nicht nur Datenschützer, sondern auch viele andere hin, wie z.B. Unternehmensberater, Rechtsanwälte und Zertifizierungsunternehmen wie der TÜV. Doch was wird sich ab Ende Mail tatsächlich ändern? Hat vor dem Hintergrund z.B. der drastisch erhöhten Sanktionen ein echtes Umdenken stattgefunden oder bleibt der Datenschutz eine ungeliebte bürokratische Bürde?

Titel: Multivariate Algorithms for Machine Scheduling Problems

Abstract: Machine scheduling problems are a long-time key domain of algorithms and complexity research.  In those problems, we are generally given a finite set J of jobs with certain characteristics, and we must find a schedule for processing the jobs on one or more machines, which also may have their individual specifications. Typical characteristics of a job are its processing time, its release date, its due date, or its importance reflected by an integer weight. A significant amount of research has been devoted in the past 60 years towards designing polynomial-time algorithms which approximate the value of optimal schedules (for various objective functions). A novel approach to machine scheduling problems are multivariate algorithms, which aim to find a provably optimal schedule at the expense of an increased run time, which is permitted to depend moderately exponentially on the job characteristics or other structural parameters. We survey some recent algorithms in this paradigm, present some novel results, and discuss several challenging open problems in this exciting research area.

Titel: Squish and squeeze – Nuclear mechanics and mechanotransduction in physiology and disease

Abstract: The nucleus is the characteristic feature of eukaryotic cells and houses the genomic information of the cell. The Lammerding laboratory is combining cell and molecular biology approaches with microfabricated devices that mimic physiological environments, live-cell microscopy, and in vivo models to investigate how physical forces acting on the nucleus, for example, in contracting muscle cells or during migration of cells through tight interstitial spaces, can challenge the integrity of the nucleus, alter its structure, and cause genomic and transcriptional changes. These processes play important roles in cellular mechanotransduction, i.e., the ability of cells to convert mechanical stimuli into biochemical signals, but can also contribute to various diseases when the nuclear structure is perturbed by mutations or altered protein expression. In particular, mutations in the nuclear envelope proteins lamin A/C are responsible for a broad spectrum of diseases (laminopathies), including Emery-Dreifuss muscular dystrophy (EDMD) and dilated cardiomyopathy. The fact that most mutations result in highly tissue-specific disease phenotypes primarily affecting skeletal and cardiac muscles, in spite of the near ubiquitous expression of lamins A/C, suggest that lamin mutations may render cells more sensitive to mechanical stress, which then causes progressive cell failure in mechanically stressed tissues. I will discuss our recent findings that highlight the importance of lamins A/C in mediating nuclear stability and mechanotransduction in mechanically stressed cells and tissues. At the same time, increased nuclear deformability, caused for example by reduced levels of lamins A/C, can promote cell migration through tight spaces with cross-sections smaller than the nuclear diameter, where the large size and rigidity of the nucleus can constitute a rate-limiting factor. I will present recent findings that demonstrate the importance of nuclear mechanics during cell migration in confined environments in vitro and in vivo, as well as the functional consequences of cells having to squeeze their large nuclei through tight interstitial spaces and small pores in the extracellular matrix network, with a particular focus on breast cancer.

Titel: RF NEMS Magnetoelectric Sensors

Abstract: The coexistence of electric polarization and magnetization in multiferroic materials provides great opportunities for realizing magnetoelectric coupling, including electric field control of magnetism, or vice versa, through a strain mediated magnetoelectric coupling in layered magnetic/ferroelectric multiferroic heterostructures [1-9]. Strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which however has been elusive, particularly at RF/microwave frequencies. In this presentation, I will cover the most recent progress on new integrated magnetoelectric materials, magnetoelectric NEMS (nanoelectromechanical system) based sensors and antennas. Specifically, we will introduce magnetoelectric multiferroic materials, and their applications in different devices, including: (1) novel ultra-compact RF NEMS acoustic magnetoelectric antennas immune from ground plane effect with < l0/100 in size, self-biased operation and potentially 1~2% voltage tunable operation frequency; and (2) ultra-sensitive RF NEMS magnetoelectric magnetometers with ultra-low noise of ~1pT/Hz1/2 at 10 Hz for DC and AC magnetic fields sensing. These novel magnetoelectric devices show great promise for applications in compact, lightweight and power efficient sensors and sensing systems, ultra-compact antennas and for radars, communication systems, biomedical devices, IoT, etc.
