Michael Pravica is an expert in general physics. He especially enjoys research focused on the study of matter at extreme conditions of high pressure, high temperature, and high radiation flux.
Pravica — well-known for his community activism and dedication to spreading the joy of science to the masses via television, radio, print media, and public forum appearances — has worked to further the field through development of several innovative concepts. They include: a) A new field of science, dubbed "useful hard x-ray chemistry," wherein high energy, penetrating and focused x-rays are harnessed to initiate novel chemistry in isolated and sealed chambers, and b) Ion Beam Nuclear Transmutation Doping, a novel method to dope wide bandgap semiconductors using penetrating, high-energy protrons initiating nuclear transmutation to create dopant layers.
He has also decades of experience using liquid helium for nuclear magnetic resonance (related to MRI technology).
A Wisconsin fire department's warning on social media about leaving sanitizer in a hot car is spreading around the nation. A photo of a burned car door was posted with a warning about the dangers of leaving hand sanitizer in a car on a hot day. It has since been taken down by the fire department, who said on Facebook the photo was just used to show the damage an open flame could cause. It begs the question -- can hand sanitizer really explode in your vehicle?

Community engagement is a critical component of the work needed for higher education leaders to begin to turn the tide and change public opinion around the industry.
I would be much less worried about something like that happening in my car as far as igniting. It would take a lot. I don't see that based on the flashpoints and the self-ignition temperature, I don't see that there'd be a real issue. I would just be more worried about somebody trying to open the top like a pop bottle and then suddenly, all this alcohol splashing in your eye.
