Unlocking the Secrets of Space Chemistry With Cold Coulomb Crystals

Posted by in categories: chemistry, particle physics, space travel

Researchers at the University of Colorado Boulder have developed experiments to replicate the chemical reactions of the Interstellar Medium, using techniques like laser cooling and mass spectrometry to observe interactions between ions and molecules.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there.

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other.

How Tetris Inspired an MIT Breakthrough in Nuclear Safety Technology

Posted by in categories: innovation, nuclear energy

The device, based on simple tetromino shapes, could determine the direction and distance of a radiation source, with fewer detector pixels.

The spread of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant in Japan in 2011 and the ongoing threat of a possible release of radiation from the Zaporizhzhia nuclear complex in the Ukrainian war zone have underscored the need for effective and reliable ways of detecting and monitoring radioactive isotopes. Less dramatically, everyday operations of nuclear reactors, mining and processing of uranium into fuel rods, and the disposal of spent nuclear fuel also require monitoring of radioisotope release.

Precision Spectroscopy Now Possible Under Starved-Light Conditions

Posted by in categories: chemistry, particle physics, quantum physics

In a study recently published in Nature, researchers from the Max Born Institute in Berlin, Germany, and the Max-Planck Institute of Quantum Optics in Garching have unveiled a new technique for deciphering the properties of matter with light, that can simultaneously detect and precisely quantify many substances with a high chemical selectivity.

Their technique interrogates the atoms and molecules in the ultraviolet spectral region at very feeble light levels. Using two optical frequency combs and a photon counter, the experiments open up exciting prospects for conducting dual-comb spectroscopy in low-light conditions and they pave the way for novel applications of photon-level diagnostics, such as precision spectroscopy of single atoms or molecules for fundamental tests of physics and ultraviolet photochemistry in the Earth’s atmosphere or from space telescopes.
