Anyone who’s visited our site before knows that we’re big fans of the ultrasonic cleaner. Ultrasonic cleaning provides a convenient and effective method for reducing surface contamination in applications from engine maintenance to surgical tool sterilization. But that doesn’t mean it’s always the best choice. For example, researchers at King Saud University in Riyadh, Saudi

I think one of the beauties of science that is poorly understood by the lay community is it’s ability to distinguish what is true from what makes sense. Although western educational institutions were founded along Aristotelian lines, Aristotle wasn’t an experimentalist. His worldview was created from a self-consistent logic. Looks nice, but it’s just not

Stoichiometry is really cool-sounding word. Well, it’s also a fascinating and subtle study. Any given chemical can participate in a range of reactions with different reactants and result in different products. The ratio of those compounds — the number of each you start with and end with — is the stoichiometry. But it really gets

Drug delivery is a big problem for the pharmaceutical industry. When you have a compound that works for a specific target, you need to make sure the drug makes it to that target. In general, there are a lot of barriers in the way, and specifically for the brain there are even more barriers. To

There’s a big difference between a solution and an engineered solution. Take the problem of biomass conversion to fuel. If you want to take an approach that makes sense — use cellulosic plant matter (the part you don’t eat) as your source — then you can say that maybe you should chop it up, or
