Doubling Beam Intensity Unlocks Rare Opportunities for Discovery at Fermi National Accelerator Laboratory

M. A. Hassan, T. Khabiboulline, J. Reid
Fermilab, IL, USA

Behind the discovery of the most fundamental and rare physical processes within our universe is powerful technology, such as the particle accelerators in use today at Fermilab. For over 40 years, one particle accelerator in particular, the Booster synchrotron, has been instrumental in providing high-intensity proton beams for particle physics experiments at the lab. A highly coordinated effort ...

Floating on Sound Waves with Acoustic Levitation

K. Suthar, C. Benmore
Argonne, IL, USA

As part of an industry that saves lives on a regular basis, pharmaceutical companies are in need of systems that can be used to deliver high-quality medicines. One method utilizes sound waves generated by an acoustic levitator with foam-coated transducers. Using the acoustic force from the sound waves, chemical particles are suspended between the transducers, where they can be mixed in a ...

Innovative Thermal Insulation Techniques Bring Vaccines to the Developing World

D. Gasperino, O. Yildirim
Intellectual Ventures, WA, USA

When medical professionals transport vaccines, their cargo needs to be kept at a cool temperature. This limits their ability to travel to regions where there is not enough electricity. Intellectual Ventures’ Global Good program designed a thermos-like container that is powered by ice and keeps vaccines cool for long periods of time. They used COMSOL Multiphysics and its Heat Transfer Module and ...

Optimizing Hematology Analysis: When Physical Prototypes Fail, Simulation Provides the Answers

D. Isèbe
HORIBA Medical, France

Hematology analysis, the analysis of a blood sample to determine a variety of hematological parameters, is a major factor in diagnostic and treatment decisions for blood diseases. Accurate blood analysis requires counting and sorting different cells in a sample to measure their sizes and distributions. HORIBA Medical, a company that supplies medical diagnostic equipment, uses COMSOL Multiphysics ...

The Thermal Management of Li-ion Battery Packs

Michele Gosso & Antonio Fiumara

Fiat Research Center, Orbassano, Italy

At the Fiat Research Center in Italy, Michele Gosso and Antonio Fiumara are working on the development of providing power for electric and hybrid vehicles. The team must combine individual lithium-ion battery pouch cells into battery packs to generate the 350V needed, while providing the packs with sufficient cooling. At the same time, they want to keep the packs as small and light as ...

Magnets Improve Quality of High-Power Laser Beam Welding

M. Bachmann, V. Avilov, A. Gumenyuk, and M. Rethmeier
BAM Federal Institute For Materials Research and Testing
Germany

High-power laser beam welding uses a localized heat source to achieve narrow deep welds and high welding rates. Engineers run into some difficulties because the use of a localized heat source often results in the distortion of metal components; spattering and the ejection of droplets from the weld pool results in underfills, undercuts, craters, blowholes, or blowouts. A stationary magnetic field ...

Optimized Induction Heating Techniques Improve Manufacturing Processes

I. Jain,
Tata Steel, India

Induction heating has become a valuable tool used by the steel industry for manufacturing various metal products. The process provides more precise heating control, uses less energy, and offers better quality assurance and reliability than traditional production processes. Tata Steel, one of the top ten steel companies worldwide, is using multiphysics simulation to analyze the electromagnetic, ...

Developing a New Microreactor for Organic Synthesis Using Microwave Heating

W. Lee, K. Jensen
MIT, MA, USA

The chemical reactions used to generate solvents and certain pharmaceuticals rely on organic synthesis, a process of combining individual chemicals that can be accelerated through microwave heating. A microreactor system facilitates the direct, localized, and efficient temperature change necessary for successful synthesis. However, a uniform temperature distribution is crucial to the chemical ...

Gaining Insight into Piezoelectric Materials for Acoustic Streaming

G. Potter
SUNY Albany, NY, USA

Many sensors, such as flow sensors and those used in medical diagnostics, rely on microfluidic devices. However, mixing and pumping fluids becomes challenging because of the small size of these devices. As an alternative to traditional actuation methods, surface acoustic waves (SAWs) can be used to create fluid streaming. Through a collaboration between SUNY Albany and SEMATECH, researchers have ...

Nanoresonators Get New Tools for Their Characterization

J. Yang, M. Perrin, P. Lalanne
CNRS, France

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not well understood, nor are the electromagnetic ...
