Published in Optica, the initial results from the platform suggest it could be valuable for real-world gas sensing applications with extremely fast acquisition speed. Photoacoustic techniques have ...

Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas. It’s not easy to see it happen in a solid but let’s try it for a ...

Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing performance of devices known as optical frequency comb ...

These ultra-precise sensors are like fingerprint scanners for molecules of gas. Scientists have used them to spot methane leaks in the air above oil and gas operations and signs of COVID-19 ...

Throughout the ice cream there are very tiny ice crystals. The gas molecules from the soda gather on these tiny crystals and become bubbles of gas. If the ice is already wet, some of the points are ...

A small amount of water is added to an aluminum soda can and brought to boiling on a hot plate or with a Bunsen burner. The water gas molecules will occupy all the space inside the can since the air ...

Particles (molecules and ions) in a liquid and a gas move continuously. Because of this movement, particles will spread themselves evenly throughout a liquid or a gas.
