In research that has all the makings of a blockbuster movie — with interstellar chemistry, million-year timescales, and high-powered lasers — Princeton chemists are expanding our understanding of the ...

From safety protocols to mastering titration and spectroscopy, building strong chemistry lab skills is key to both academic success and future professional work. New approaches combine multimedia ...

Dealing with this volume of plastic garbage is already a tremendous challenge, but the discovery of microplastics in isolated ...

Infrared and Raman spectroscopies can observe different types of molecular vibrations. Using both methods on a compound provides a more complete molecular picture than either alone. But the two ...

In Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

WEST LAFAYETTE, Ind. — The clock is ticking when a neurosurgeon is trying to remove a brain tumor but also determining its malignancy and type. Instead of sending samples to a lab where the necessary ...

Raman spectroscopy is a powerful analytical technique in part because of the high signal-to-noise ratio. If regular absorption spectroscopy is like viewing the noonday sky through a stained glass ...

Near-infrared (NIR) spectroscopy provides a rapid and cost-effective method for food-allergen detection. Over 15 million people in the US have a food allergy. Even trace amounts of a substance can ...
