Accounting for Heat in the Design of Lithium-Ion Batteries

October 9, 2014

In the performance of lithium-ion batteries, thermal management is an important element to consider. Through modeling and simulation, you can improve the design process by analyzing how heat is transferred within the energy source.

Sometimes a Cigar Is More Than Just a Cigar

September 10, 2014

As a chemical engineer, I can’t just smoke a cigar and leave it at that. Here, I investigate the anatomy, structure, and chemical process zones of a cigar and show you a simple model of the temperature distribution of the smoke in a cigar as well as the concentration of oxygen.

A Strategy for Designing Corrosion-Resistant Materials

September 3, 2014

Billions of dollars are spent each year in the U.S. to repair corrosion damage. To help reduce the high cost of corrosion, engineers at the Naval Research Laboratory (NRL) in Washington, D.C. are using multiphysics simulation to gain a better understanding of the fundamental mechanism. A successful research outcome at NRL will establish the correlation between metal microstructure, corrosion, and mechanical strength. Material designers could then develop stronger, corrosion-resistant materials using this new information.

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.
