In this second part of the webinar series on rheometric applications, we explore advanced applications of Optimally Windowed Chirps (or OWCh) to characterize complex material systems, including aging thixotropic systems such as clay dispersions. We describe how user control of the initial phase and the frequency slew rate of the chirp, which is a new approach to rapidly obtain frequency dependent material behavior, can be leveraged to improve data quality for very short chirps or highly viscoelastic samples.

In this two‑part webinar, we illustrate how modern broadband rheometric techniques can be used to measure the material functions of what may broadly be referred to as mutating materials (or changing materials), with rheological properties that are both time‑ and frequency‑dependent.

In this webinar, we will introduce a simple, scalable, and reliable edge–exfoliation method that uses office sticky tape to produce flexible and transferable polycrystalline diamond membranes. This innovative technique allows for the mass fabrication of large-area, sub-micrometer thick, ultra-flat, and highly flexible diamond membranes that are compatible with standard manufacturing processes. The flexibility of the membranes unlocks new possibilities in elastic strain engineering and deformation sensing. We will also share insights into the use of flexible diamond membranes in semiconductors , quantum technology, and other applications. This work opens exciting avenues for integrating diamond-based materials into next-generation devices (i.e.: 4th generation semiconductors, and high-power and high frequency electronics) and demonstrates the future of flexible diamond membranes.

In this webinar, we will introduce the basics of lidar remote sensing and the fluorescence lidar technique. The weak intensity of the fluorescence return signal poses high demands on the efficiency of the optical components that are used. Furthermore, measurement examples are shown to illustrate how the fluorescence lidar technique advances the lidar-based characterization of atmospheric aerosol particles. As the fluorescence process is unique to certain (biogenic) aerosol particles (air molecules, for example, do not exhibit fluorescence), the fluorescence technique enhances the detection sensitivity, especially of highly fluorescent aerosol types (like wildfire smoke), by providing particle-only information.

This webinar presents practical measurement strategies for these challenging scenarios using three complementary non-contact techniques: Thermo-Optical Plane Source (TOPS), Frequency and Steady-State ThermoReflectance (FASTR), and Lock-In Thermography (TOPS-LIT). Through real experimental examples, the session will demonstrate how these methods measure thermal conductivity, thermal boundary resistance, volumetric heat capacity, emissivity, and thermal diffusivity across a wide range of materials and length scales.

In this webinar, we will review the history of tenpin bowling and learn why throwing the perfect strike is the goal and what goes into achieving it. We will look at how the sport has changed over recent decades and advances in technology that have changed the strategy and technique that bowlers use. We will touch briefly on the constant battle in the sports industry between equipment manufacturers who want maximum performance, and governing bodies who want to maintain the integrity of the sport.

The webinar will explore how the mud's unusual composition creates a material that "spreads like skin cream and grips like sandpaper". We'll examine the rheological measurements that reveal the mud's shear-thinning behavior, driven by clay and organic cohesion, which enables it to uniformly fill pores in the leather surface. Tribological experiments demonstrate how the cohesive residue doubles contact adhesion while sparse angular sand grains, bonded by clay particles, create a studded surface that enhances friction.

This webinar will explore the nuclear and atomic physics that lie at the heart of positron emission tomography (PET) imaging technology, and the critical role that positrons (antimatter electrons) serve in image creation. We will cover new technological and engineering developments that continue to drive PET scanners to higher sensitivities and resolution, and new radiopharmaceutical developments that are expanding the use of PET in both the research and clinical domain. Some of the more common and exciting clinical and research applications of PET imaging will be presented in detail. This webinar will include a discussion of the purposeful design of radiopharmaceuticals (drug molecules radioactively tagged with a positron-emitting radionuclide) to bind to highly specific molecular targets that elucidate the biochemical signatures of particular diseases.

In this webinar, we will present a brief history of the field and highlight key insights, breakthroughs, and lingering unknowns. In particular, we will illustrate the importance of nanoscale characterization and modeling in materials that are challenging to synthesize, and emphasize the close feedback required between theory, growth, and characterization. We will also discuss some prominent questions, including how the two families of nickelates are similar yet different, both to each other and to other unconventional superconductors such as the cuprates.

Wearable electronics for non-invasive personal health monitoring require advanced multimodal sensing and seamless energy system integration. However, current platforms are hindered by insufficient energy budget, limited sensing performance, user discomfort, complex circuit architectures, and bulky device form factors. In this webinar, we present a wireless, energy-autonomous, sweat sensing system based on a wearable microgrid framework. This system integrates high-efficiency, self-voltage-regulated microgrids—comprising wearable energy harvesters (similar to electrochemical biofuel cells) and flexible rechargeable batteries—to harvest and manage energy from the body.
