Acoustic wave lab-on-chip is now flexible, bendable and potentially wearable! (Prof. Richard Fu, Newcastle)

28.05.2018 von 17:15 bis 18:00

Institute Ostufer, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

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.

Wires, trusses and pillars produced by assembly of plasma generated nanopartices (Prof. Dr. Ulf Helmersson, Linköping University, Schweden)

29.05.2018 ab 16:15

Abstract

Nanoparticles generated or supplied to a plasma attains a negative potential due to the nature of the plasma. This open up interesting possibilities in synthesis and assembly of the nanoparticles creating structures in the nano- and micro-range. In this work, we use hollow cathode sputtering powered with high-power pulse to ensure close to full ionized of the source material. This promotes rapid growth of the nanoparticles to desired sizes and the negative charge makes it possibility to guide nanoparticles for assembly and collection on desired positions. This is demonstrated by attracting na-noparticles to substrate positions with a positive potential and focusing nanoparticles through a matrix of electrostatic lenses to assemble the nanoparticles into pillars. For ferromagnetic nanoparticles, we also demonstrate generation of nanowires as well as nanowires cross-linked into trusses. Since the iron nanoparticles are generated under relatively pure condition they assemble into wires without oxides in the interfaces. Nanowires and trusses assembled on conducting substrates can potentially be used as low cost large area electrodes.

Cells and tissue as active materials (Prof. Dr. Ulrich Schwarz, Heidelberg)

04.06.2018 von 16:00 bis 16:45

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

Abstract:

Biological systems such as cells and tissue use non-equilibrium processes to actively generate mechanical stress, movement and growth. Some of these processes can actually be reconstituted in biomimetic experiments with active soft matter. In this talk, we first discuss why and how contractile forces are generated by biological systems and how they can be measured, for example on soft elastic substrates. We then discuss how these contractile systems can be mathematically described by classical continuum mechanics extended by active elements. We finally explain how the local contractility of cells and tissue can be controled with optogenetics, and how the resulting forces and flows can be used to estimate their material properties.

ICE CUBE and the Discovery of High-Energy Cosmic Neutrinos (Prof. Dr. Francis Halzen, University of Wisconsin)

12.06.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

The IceCube project has transformed a cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects more than 100,000 neutrinos per year in the GeV to PeV energy range. Among those, we have isolated a flux of high-energy cosmic neutri-nos. I will discuss the instrument, the analysis of the data, the signi-ficance of the discovery of cosmic neutrinos, and the recent multi-messenger observation of a flaring TeV blazar in coincidence with the IceCube neutrino alert IC170922. The large cosmic neutrino flux observed implies that the Universe’s energy density in high-energy neutrinos is the same as that in gamma rays, suggesting that the sources are connected and that a multitude of astronomical objects await discovery.

RF NEMS Magnetoelectric Sensors (Northeastern University, Boston)

18.06.2018 von 17:15 bis 18:00

Technische Fakultät, Gebäude D, Kaisterstraße 2, Aquarium

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.

Particle Physics after the Higgs Discovery: Where do we go? (Prof. Dr. Thomas Mannel, Siegen)

26.06.2018 ab 16:15

Hans - Geiger - Hörsaal (LS13 - R.52) des Physikzentrums

Abstract

After the recent discovery of the Higgs boson the so-called Standard Model of particle physics has become a complete and mathematically consistent theory, which – at least in principle – could be valid up to extremely high energies. In this talk I will discuss, why research in particle physics is still well motivated, although the Higgs boson is discovered. I will consider on the one hand the theoretical problems of the standard model, on the other hand, I will discuss experimental hints, why the standard model cannot be the final theory of the fundamental interactions.

Referent: Prof. Dr. Thomas Mannel (Universität Siegen, Germany)
