Hygroscopy of Brown vs. White Sugar, the Banana Bread Test

September 11, 2014

Baking is just like chemistry class, except you get to eat the results. Today, we narrow in on one ingredient in particular: sugar. More than just a sweetener, sugar serves several other purposes in baking. For one, it keeps our baked goods moist thanks to its hygroscopic properties.

2D Axisymmetric Model of a Conical Horn Antenna

September 4, 2014

We’ve blogged about how you can save time setting up your electromagnetic models by using symmetry, anti-symmetry, and periodic boundary conditions. Today, we’ll show you a model that takes advantage of axisymmetry — a conical horn antenna model.

The Hygroscopic Swelling Effect

August 19, 2014

There have been many studies of how specific materials are affected by hygroscopic swelling. Let’s explore what hygroscopic swelling is and the effect it may have on engineering designs.

Eat First, Research Later: Exploring the Role of Eggs in Baking

August 5, 2014

We tend to do some research before taking to the lab, but when it comes to baking, I’ve been operating in the reverse. In this lighter blog entry, we explore the role of eggs in baking by comparing traditional recipes with vegan versions as well as more modern baking techniques. Chemistry experiments you can eat? Yes, please.

Modeling Lithium-Ion Batteries for Quality and Safety Assurance

July 18, 2014

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.

Happy Birthday, Nikola Tesla

July 10, 2014

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.

New Book on Topology Optimization for Electromagnetics

July 7, 2014

There’s a new book out there for those of you who work with or research electromechanical system design. It’s titled Multiphysics Simulation: Electromechanical System Applications and Optimization and is more than your average textbook. This is a reference guide on simulation and topology optimization written with both students and industry engineers in mind.

Vacuum Tube Plus MOSFET Equals Vacuum Transistor

July 4, 2014

IEEE Spectrum recently sent out a “Tech Alert” that included an article about vacuum transistors, which combine vacuum tubes and metal oxide semiconductor field-effect transistors (MOSFETs). The article suggests that this technology may wind up replacing traditional silicon transistors.
