Modeling Electrochemistry for Managing Diabetes

August 14, 2014

Diabetes is an incurable global killer: the World Health Organization estimates 350 million diabetics worldwide, with an average annual fatality rate close to 1%. Fortunately, modern medical science enables diabetics to manage their glucose levels and intake, so many countries have seen greatly reduced danger of the disease. Many diabetics must track their glucose levels throughout the day, requiring an accurate method for measuring the concentration of glucose in blood. For modern sensor designs, the method of choice is electrochemistry.

Isoelectric Focusing and the Migration of Chemical Species

July 21, 2014

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

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.

Modeling High-Performance Liquid Chromatography

June 13, 2014

Some chemical applications call for identification and quantification of the components in a chemical mixture. High-performance liquid chromatography (HPLC) is a versatile separation technology for chemical species. To learn more about the separation process, we can model it with simulation software.

Intro to Corrosion Modeling for the Oil and Gas Industry

May 22, 2014

If you work in the oil and gas industry dealing with offshore drilling, corrosion is your worst enemy. A corroded oil platform is a dangerous platform and it can cost you a lot — in both lives and money. To avoid such a dark fate, you need to safeguard the steel structure from corrosion via a protection system, such as the cathodic protection process shown here.

Ammonia Synthesis, a Complex and Nonlinear Process

May 8, 2014

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.

Electroplating: How the U.S. Mint Makes a Penny

April 17, 2014

What’s a penny made of? Though they appear to be solid copper coins, they actually don’t contain much copper at all these days. Instead, the U.S. Mint saves money by applying only a veneer of valuable metal onto a less expensive one. Have you ever thought about the manufacturing process by which this is achieved? Let’s find out.

Chemical Parameter Estimation Using COMSOL Multiphysics

April 10, 2014

The last two blog posts in the Chemical Kinetics series were concerned with modeling chemical reactions based on a particular set of parameters. While this is important and of great academic and industrial interest, the relevant parameters were assumed. Now, let’s find out how to estimate the chemical parameters using COMSOL Multiphysics.
