EuroTechTalks: Tackling global challenges together

The EuroTechTalks are a series of scientific online lectures by renowned researchers of EuroTech Universities. In the Alliance, we tackle global challenges together. This series highlights some of our scientific collaborations.

“None of us is as smart as all of us,” says American author Ken Blanchard, and rightly so. The cornerstone of the EuroTech Universities Alliance is cooperation. We put a spotlight on some of the excellent collaborative research conducted at the six EuroTech schools.

The EuroTechTalks lecture series gives the floor to renowned researchers from EuroTech Universities who, as a team, introduce us to their work, provide a glimpse into their latest findings, and present selected projects.

Atomic concurrent objects, whose operations take place instantaneously, are a powerful technique for designing complex concurrent programs. Since they are not always available, they are typically substituted with software implementations. A prominent condition relating these implementations to their atomic specifications is linearizability, which preserves safety properties of programs using them. However linearizability does not preserve hyper-properties, which include probabilistic guarantees about randomized programs. A more restrictive property, strong linearizability, does preserve hyper-properties but it is impossible to achieve in many situations.

In particular, we show that there are no strongly linearizable implementations of multi-writer registers or snapshot objects in message-passing systems. On the other hand, we show that a wide class of linearizable implementations, including well-known ones for registers and snapshots, can be modified to approximate the probabilistic guarantees of randomized programs when using atomic objects.

Past talks

In this joint seminar, we will present the complementary expertise and recent research of our two groups at Ecole Polytechnique (France) and EPFL (Switzerland) on magnetorheological elastomers (MREs); a novel class of active materials capable of exhibiting a coupled response under external magnetic and/or mechanical stimuli.

These solids are composites comprising magnetic micron-sized particles embedded randomly in a polymer matrix. MREs can be categorized into soft- and hard-MREs. Soft-MREs are typically made of carbonyl-iron particles and tend to exhibit no magnetic dissipation, while they lose their magnetization when the magnetic field is switched off. Hard-MREs, which are made of permanently magnetizable particles (e.g., NdFeB), are dissipative magnetically and retain a remanent magnetization in the ground state; i.e., they are compliant permanent magnets.

In this talk, we will focus on the fabrication, experiments, and modeling of MREs, especially in leveraging their instabilities for function, to deliver configurational and geometrical changes with minimal external magnetic fields. Examples of novel applications related to biomedical devices and soft robots will be discussed.

Within the EuroTechTalk, Prof. Kizel and Prof. Wudy will present the cutting-edge research they would like to conduct with 8 other partners in the newly funded EU project InShaPe. The overall aim of the InShaPe project is to develop and demonstrate in different industrial use cases (energy, aerospace and automotive) a novel first-time-right Powder Bed Fusion Process of Metals using Laser Beam (PBF-LB/M). The novel PBF process will be underpinned by two technical innovations:

(i) the flexible adaptation of laser beam shapes tailored to the material/geometry of the printed parts (enabled by a first-of-a-kind optical module for beam shaping enhanced with AI-techniques to determine the right beam shapes); and

(ii) the multispectral in-line process monitoring and control system (enabled by transferring know-how from the multispectral analysis domain into additive manufacturing).

InShaPe will disrupt the manufacturing sector by helping to turn PBF-LB/M from a niche into a mainstream manufacturing technology.

Speakers:

  • Prof. Katrin Wudy, Professorship for Laser-based Additive Manufacturing, Technical University of Munich
  • Prof. Fadi Kizel, Department of Mapping and Geoinformation Engineering, Civil & Environmental Engineering, Technion – Israel Institute of Technology
In this EuroTechTalk we will present nanophotonic and single-molecule biosensors that are being investigated at TU/e and EPFL, including research in the CONSENSE program, a European network that focusses on continuous biosensing technologies for personal health. Prof. Prins will present biosensors for the continuous monitoring of biomolecular targets, based on measuring Brownian motion of microparticles. The sensors employ particles on a surface, where the particles as well as the surface are provided with specific binder molecules. Motion traces are recorded of hundreds of particles, each revealing digital binding and unbinding events. The events are statistically analyzed and related to the biomarker concentration in solution. Large molecules (proteins, nucleic acids) and small molecules (oligonucleotides, metabolites) are being measured across a wide range of concentrations (picomolar to millimolar). Applications in industry and healthcare will be discussed, for early warning and closed-loop control based on real-time biochemical data. Prof. Altug will present nanophotonic technologies for optical biosensors, bioimaging and spectroscopy, based on nanofabrication, microfluidics, surface chemistry and data science. Nanoplasmonic and dielectric metasurfaces are developed for increased light-matter interaction in targeted spectral ranges including visible, near-infrared and mid-infrared. Nanofabrication methods allow high-throughput and low-cost manufacturing of nanophotonic structures and integration with microfluidics for automated sample handling. Data science tools with hyperspectral imaging and spectroscopy enable high device performances. Recent progress will be presented as well as prospects for applications. Speakers:
