Becker serves as a consultant for Austria - based gas analysis instrument - maker Ionicon Analytik, GmbH, which makes proton transfer reaction — mass spectrometry (PTR — MS) technology that the company claims can distinguish substances having very similar molecular structures as well as correctly identify explosives, chemical warfare agents and substances that could be combined to create a bomb.

The scientists used a chemical detection device called a proton - transfer reaction mass spectrometer to, for the first time, track the odors emitted by flowers in the wild just as moths might encounter them.

When a plant uses the sun's energy to split water molecules, it shuttles hydrogen (separated as protons and electrons) into a reaction sequence to help it grow.

The catalyst acts as a chemical handler, shuffling around the water molecules» assets — electrons, hydrogen ions (protons), and oxygen atoms — to get the reaction to happen.

Starting from the constituent protons and neutrons and the fundamental interactions among them, this method has brought a leap forward (unimaginable until only nine years ago) in the ability to accurately describe reactions between light ions in a thermonuclear environment, as well as the structural properties of exotic nuclei.

By combining two simple, inexpensive, metal - free catalysts, they sped the cell's slower reaction, taking protons and electrons derived from the hydrogen fuel and combining them with oxygen to pump out water, a reaction known as the oxygen reduction reaction.

As in plants, their system consists of two linked chemical reactions: one that splits water (H2O) into protons and oxygen gas, and another that converts CO2 into carbon monoxide (CO).

When protons from GCRs collide with the nitrogen - 14 (seven protons plus seven neutrons in the nucleus) in the air, carbon - 14 is created (in addition to other isotopes such as beryllium - 10) through a nuclear reaction:

The scientists made on - the - spot measurements of 100,000 vehicles as they drove past air - sampling probes (including a for the first time a proton transfer reaction time - of - flight mass spectrometer; it provided the time resolution required for the plume capture technique used in the study) on College Street, one of Toronto's many major roadways.
