Studying the Safety of Tattoos with Mass Spectrometry and X-Rays

Brianne Costa January 12, 2018

“Where?” “Of what?” “Why?” These are questions often asked of someone who is planning on getting a tattoo. Another common question: “Is it safe?” You can vet the cleanliness of a tattoo parlor and the artist’s qualifications, but there hasn’t been much research into what happens to ink once it enters the body. A research group recently investigated if tattoo pigment can harm skin and the lymphatic system using techniques such as mass spectrometry and X-ray fluorescence.

Want a roadmap to modeling cables? We have a six-part tutorial series for you. The Cable Tutorial Series shows how to model an industrial-scale cable in the COMSOL Multiphysics® software and add-on AC/DC Module, and also serves as an introduction to modeling electromagnetic phenomena in general. The numerical model is based on standard cable designs and validated by reported figures. Keep reading for a sneak peek of what you’ll learn when you roll up your sleeves and start the series.

Magnetic flow meters are a noninvasive option for measuring blood flow. However, when patients move, displaced blood vessels can affect the sensitivity of the flow meter. Researchers from ABB Corporate Research used multiphysics modeling to study how the displacement of blood vessels in a moving patient impacts the performance of a magnetic flow meter.

There is a lot we know about the brain, and a lot we don’t. Optogenetics is a relatively new area of study in which light is used to stimulate brain activity and study neurological behavior. Stimulating neurons with light is more precise than electrical stimulation — and safer. Researchers from Massachusetts Institute of Technology (MIT) used simulation to design an optical probe that can be implanted into the brain to stimulate nerve impulses.

My favorite novel to read around the Halloween season is Stephen King’s It. A common misconception about the book is that “It” is just a scary clown — It is actually the embodiment of whatever you fear most. If what scares you the most is the possibility of ghosts, don’t worry: a researcher used acoustics analysis to explain that whatever scares you this Halloween, like It, is just a trick of the mind (and vibroacoustic effects…)

Imagine that reading books with no pictures and 12-point font is all you know. One day, someone hands you a pair of 3D glasses and takes you to see a movie. This is how thousands of researchers and scientists in astrophysics might feel right now — they have been closely working on the recent groundbreaking gravitational waves discovery that enables us to get a clearer, brighter view of the universe.

“I think I can safely say that nobody understands quantum mechanics.” — Richard Feynman, in The Character of Physical Law (1965). Although the Nobel-prize-winning physicist might have been speaking in jest, quantum mechanics is a difficult concept to teach — and simulate. Modeling a double-barrier structure in the COMSOL Multiphysics® software can help teach quantum mechanics concepts to physics students as well as enhance the research and development of semiconductor devices.

A leading cause of smog and particulate pollution is the harmful emissions from automobiles, especially those that run on diesel engines. Today, most vehicles with diesel engines are required to install a diesel particulate filter (DPF) to catch carbon-based particulates that are emitted from their exhaust. Using the COMSOL Multiphysics® software, we can analyze the acoustics of a DPF.

We thrive on the ability to stay constantly connected to the rest of the world through technology. But there are times when our devices hold us back, distracting us when we should be working on an important project or connecting with friends over dinner. Fortunately, a device that was first theorized over 200 years ago — the Faraday cage — offers a way to take ourselves offline, if only for a little while.

When designing needles for drug delivery, one major challenge is balancing the comfort of the patient with the effectiveness of the injection. By applying an approach that combines “first principles” thinking and modeling, Eli Lilly and Company optimized the design of a needle for an insulin injection pen, while keeping patient experience in mind. In a keynote talk from the COMSOL Conference 2016 Boston, Bernard McGarvey of Eli Lilly discusses this process.
