Owing to the worldwide helium shortage, many labs are facing difficulties in maintaining their supply, of one the most commonly used carrier gases for gas chromatography (GC) and as a consequence are facing rapid price increases. Many chromatography labs are therefore looking for alternative carrier...
A basic hologram is easier to setup than you might think. HowStuffWorks It doesn't take very many tools to make a hologram. You can make one with: A laser: Red lasers, usually helium-neon (HeNe) lasers, are common in holography. Some home holography experiments rely on the diodes fro...
His theory was inspired by the less common isotope of helium, namely 3He4, the first experimental platform for testing the theory. Decades later, the theory was also applied to strongly correlated metals, known as heavy-fermion systems5. Leggett, reviewing liquid 3He6, writes that it is “...

Many people believe that air molecules don't weigh anything, but they do (see the page on helium to get a better picture of the weight of air). When you throw them out the nozzle of a balloon, the rest of the balloon reacts in the opposite direction. Next, we'll look at another ...
Most fish rise and sink in the water the same way a helium-filled balloon or a hot air balloon rises and sinks in the air. To see how this works, you need to understand the various forces at work in the air and underwater. While these environments seem very different to us, water ...
Helium Tanks and other sealed Tanks Cars that have not been drained of fluids. All of these things are just the tip of the iceberg when it comes to following scrap yard guidelines and is not easy to maintain at a high level unless you follow your own internal rules very closely. ...
When the solid rock changes form to a more liquid rock material, it becomes less dense than the surrounding solid rock. Because of this difference in density, the magma pushes upward with great force (for the same reason the helium in a balloon pushes up through the denser surrounding air ...
However, hydrogen is also very flammable -- a fact that has prompted many explosion-shy weather stations to adopt helium instead. Altogether, a complete weather balloon assembly costs about a few hundred dollars. A high-altitude rocket, on the other hand, can cost several hundred thousand ...
The carbon dioxide (gas) reacts with sodium hydroxide and calcium hydroxide to form calcium carbonate (solid). Replace oxygen that you have consumed. Small tanks of pure oxygen or mixed gases (nitrogen-oxygen or helium-oxygen) inject fresh oxygen into the breathing loop. Control the oxygen ...
