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.

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.

Quantum Focus series, session 2 of 3—Ultracold fermionic atoms in optical lattices offer a clean and highly controllable platform to emulate the fermionic Hubbard model. In this webinar, I will present our recent progress in quantum simulations of the FHM.

Quantum Focus series, session 1 of 3—In this webinar, we explore how recent advances in quantum hardware and algorithms are revolutionizing quantum chemistry, a field that underpins vital R&D in drug development and materials science. This timely and accessible webinar walks the audience through the limitations of classical computational methods and how quantum computers promise to overcome them—especially for complex, strongly correlated molecular systems that defy today’s simulation capabilities.

This webinar will offer insight into the fundamental physics of extreme confinement, and guidance for the design of next generation nanofluidic devices. It is aimed at physicists, chemists, materials scientists, and engineers eager to explore the surprising and exploitable behaviors of matter at the smallest scales.

In this webinar, we will outline inertial confinement fusion (ICF) and inertial fusion energy (IFE) principles, including indirect- and direct-drive schemes; review achievements; and discuss steps toward practical IFE.

Despite a half-century of advancements, global MRI accessibility remains limited and uneven, hindering its full potential in healthcare. Initially, MRI development focused on devices with low magnetic fields—around 0.05 Tesla—but progress halted after the introduction of the more accurate 1.5 Tesla whole-body superconducting scanner in 1983. We developed low-cost MRI scanners that Uses permanent 0.05 Tesla magnets and deep learning.

Directed energy weapons (DEWs) based on lasers and microwaves have been in development for over 60 years but until recently had little military utility. The latest DEWs are electrically powered and are small enough and efficient enough for operation on vehicles. Now military services around the world are building DEWs as tactical weapons and deploying them in real military operations. We explain what's new about the technology and show examples of the new DEWs in the field.

In this webinar, we will introduce the fundamentals of X-ray imaging and present the current state-of-the-art in nanoscale tomography. We will focus on a technique called ptychographic X-ray computed tomography and our recent innovations that enabled the highest 3D imaging resolution to-date.
