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.

Treating Damaged Biological Tissue with Cryotherapy

August 13, 2014

With advancements in modern technologies, treating damaged biological tissue has become a quicker, less painful process. Techniques, like cryotherapy, can be used to treat internal and external tissue damage, while causing relatively little discomfort for patients.

Phase Change: Cooling and Solidification of Metal

August 12, 2014

Modeling phase change is important for many thermal processes, ranging from the food industry to the metal processing industry. The Heat Transfer Module offers a dedicated interface for modeling the characteristics of phase change. It uses the apparent heat capacity method, which we introduce here.

Simulating Wear in COMSOL Multiphysics

August 8, 2014

Today, we invite guest blogger Nagi Elabbasi of Veryst Engineering to share the work they performed on simulating wear in COMSOL Multiphysics. Using COMSOL Multiphysics, we implemented a wear model and validated it by simulating a pin-on-disc wear test. We then used the model to predict wear in an automotive disc brake problem. The results we found showed good agreement with published wear data.

The Age of 3D Metal Printing

August 7, 2014

In the past, we have discussed the importance of material selection in 3D printing and how it can affect the integrity of the final product. With advancements in technology, the industry has evolved from the production of more simple materials, like plastics, to those of greater difficulty, such as metals. Here, we take a more in-depth look at 3D metal printing and its potential to revolutionize the manufacturing process.

Modeling a Complementary Split Ring Resonator with Ease

August 6, 2014

Last month, my colleague Alexandra Foley introduced an RF modeling example that uses periodic boundary conditions. Another RF model that can be created with ease by taking advantage of periodic boundary conditions is the Frequency Selective Surface, Periodic Complementary Split Ring Resonator model.

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.

Electron Energy Distribution Function

August 4, 2014

The electron energy distribution function (EEDF) plays an important role in plasma modeling. Various approaches can be used to describe the EEDF, such as Maxwellian, Druyvesteyn, or using a solution of the Boltzmann equation. Today, we will demonstrate the influence the EEDF has on a plasma model’s results. Additionally, we present a way to compute the EEDF with the Boltzmann Equation, Two-Term Approximation interface.
