  • Process to 3D print piezoelectric materials developed

    The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade thanks to work discussed. Xiaoyu 'Rayne' Zheng, assistant professor of mechanical engineering in the College of Engineering, and a member of the Macromolecules Innovation Inst more

  • New method measures 3D polymer processing precisely

    Recipes for three-dimensional (3D) printing, or additive manufacturing, of parts have required as much guesswork as science. Until now.  Resins and other materials that react under light to form polymers, or long chains of molecules, are attractive for 3D printing of parts ranging from architectural more

  • Breaking the bond: To take part or not?

    Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exc more

Infrared (IR) Spectroscopy

I’ve been covering infrared spectroscopy recently with one of my A level classes, and realised that I haven’t really come across an aesthetically appealing reference chart for the frequencies of absorption – which seemed like as good an excuse as any to make one myself. So, here it is! Now, if you’r more

Molecular vibration

Molecular vibration A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is known as a vibration fr ... more
