Webinars

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.

Charged particle therapy is the most advanced type of radiotherapy in oncology. Recent evidence from randomized clinical trials shows that particles can reduce toxicity and improve survival in selected patients. Particle therapy is very sensitive to positioning uncertainties and organ movements, however, which can jeopardize its precision. In this webinar, we will introduce the rationale for therapy with accelerated ions, review recent clinical evidence, and show new preclinical experiments that reduce range uncertainties. These experiments use radioactive ion beams (carbon-11 ions) that can be visualized by positron emission tomography (PET)—an "aim-and-shoot" approach that allows real-time adaptation during the treatment.

Join us for this webinar to learn about the capabilities of the COMSOL Multiphysics® software and its add-on modules for designing power electronics. We will cover the specialized functionality in the add-on AC/DC Module for modeling a variety of capacitors and power magnetic devices, such as inductors and transformers. The module's functionality for extracting lumped parameters for circuit-level simulation will also be discussed. Then, we will go over how electromagnetic interference (EMI) and electromagnetic compatibility (EMC) analyses can be conducted using the add-on RF Module. In addition, we will cover how the software's multiphysics capabilities enable users to couple electromagnetics with heat transfer and fluid flow in order to design efficient thermal management systems.

In partnership with The Society of Rheology. This webinar brings together insights from three advanced rheological studies to show how flow behavior and structural analysis can be leveraged to optimize both slurry-based and dry-powder electrode formulations.

Quantum Focus series, session 3 of 3—In this webinar, we will illustrate an autonomous quantum refrigerator that can reset computational qubits in a superconducting-qubit quantum computer. In a proof-of-principle experiment, the refrigerator cooled an initially excited qubit to approximately 22 mK, lower than the temperatures achieved by some state-of-the-art reset protocols. Also, we will propose criteria for building useful autonomous quantum machines, inspired by DiVincenzo’s for useful quantum computers.
