Isoelectric Focusing and the Migration of Chemical Species
In chemistry, separation using differences in migration patterns plays an important role in understanding the properties of different chemical species. To help identify small chemical differences between molecules, researchers use a type of electrophoresis known as isoelectric focusing. With the use of an applied electric potential, this technique helps to define and separate molecules based on their varying isoelectric points. Let’s take a closer look at this separation method.
Modeling Lithium-Ion Batteries for Quality and Safety Assurance
When it comes to lithium-ion batteries, quality and safety are top priorities. Assessor of 20,000 batteries per year, Intertek Semko AB understands this perhaps better than anyone else.
The Physics Behind Baseball Pitches
Professional baseball pitchers are able to make a baseball move left, right, down, and even up (sort of) to get it by the opposing batter. The physics behind this can be explained by the Magnus effect.
Acoustic Levitation Puts a Pure Spin on Medicine Fabrication
The need for a contaminant-free space to manufacture medicine has led scientists to try many creative new approaches to improve the process. At Argonne National Lab, creating a device that floats and rotates chemical compounds in thin air was just the answer they were looking for. It meant two important changes: the amount of each chemical necessary could be implemented very precisely and the risk of outside impurities disrupting the results was minimized.
Improving Atmosphere Revitalization for Manned Spacecraft
In order to carry astronauts safely beyond earth’s atmosphere to where they can explore outer space, spacecraft must provide a very important chemical mixture: breathable air. Given the limits on space and weight for a manned shuttle, the systems flying aboard the craft must revitalize the air inside rather than carry the full amount needed for a mission. With this in mind, a team at NASA has developed an approach to atmosphere revitalization that relies on water adsorption.
Exploiting Symmetry to Simplify Magnetic Field Modeling
Whenever modeling magnetic fields in steady-state, transient, or frequency domain with the AC/DC Module, we want to reduce the size of the model as much as possible to minimize the computational resources and time needed to solve the model. Today, we will introduce the three types of symmetry boundary conditions that you can exploit in your modeling and show how to use them.
A Recipe for Success at Whirlpool Corporation
There are many factors that go into designing the ideal oven — supreme cooking capability is a must, but energy efficiency and the use of materials with reduced environmental impact is also important. How can all of these different factors be combined to create an oven that is optimized for the best performance? Engineers working at Whirlpool Corporation along with the European green energy initiative, GREENKITCHEN project, found that multiphysics simulation was vital to the success of their design process.
Happy Birthday, Nikola Tesla
On this day in 1856, a boy was born in the middle of the night during a lightning storm. Today, we remember that boy as the brilliant man he grew into — the man who contributed immensely to science and engineering: Nikola Tesla.
