If you walked into a particle or nuclear physics center, like the world-renowned CERN, you may come across a magnetic quadrupole lens (after security clearance, I would imagine). Here, we’re going to discuss what magnetic quadrupole lenses are and study the focusing effect three consecutive quadrupole assemblies have on B5+ ions traveling through such a lens.

The power electronics industry is responsible for products used by billions of people: smartphones, televisions, certain car parts, and even components in motors and household objects. With such a diverse array of applications, many design requirements are considered during the making of these products, including power and energy density, cost, and customer safety. Arkansas Power Electronics International (APEI), a USA-based company, is refining designs for power packaging to control thermal management in power electronics devices, increase efficiency, and lower cost.

We have the pleasure of introducing guest blogger, Mark Yeoman of Continuum Blue, who showcases what they can do for clients in the electromechanical brake field. Electromechanical brakes come in various designs, including single to multiple friction-face systems, power-off and power-on types, and those that include permanent magnets. With so many options, how do engineers make the right design choices for their application? With COMSOL Multiphysics, this can easily be done. Here, I will show you how.

We have made a video tutorial for those of you who want to learn how to model stresses and strains in COMSOL Multiphysics. In under five minutes, we walk you through the modeling steps from setting up parameters and geometry to postprocessing the results. For simplicity’s sake, we use a wrench and bolt model to demo the concept.

In this final installment of our Chemical Kinetics series, we will look at one of the major chemical syntheses of the modern era. This is a process that every single one of us has benefited from, whether we know it or not: ammonia synthesis. It has become one of the most studied reactions in history, its intricacies and complexities are the subject of several textbooks, and its history is a complex tale of good and evil.

Superconductors are used in applications where high current density and magnetic fields are present — including electric generators, biomagnetic technology, and common products, such as fast digital circuits. Theoretically, an unlimited amount of current can flow through a wire made of a superconducting material. However, what happens to a superconductor as the current density exceeds critical limits? Let’s find out.

According to AMPHOS 21, a COMSOL Certified Consultant, one of the proposed solutions to releasing carbon dioxide (CO2) into the atmosphere is to store the CO2 in geological formations, a technique referred to as carbon dioxide sequestration. This notion led the engineers at AMPHOS 21 to study the physical and chemical processes that occur during the injection of the gas into earth’s subsurface.
