elastic tissue that stretches and constricts as you breathe. The airways that bring air into the lungs (thetracheaandbronchi) are made of smooth muscle and cartilage, allowing the airways to constrict and expand. The lungs and airways bring in fresh, oxygen-...
Guide Everything you need to know about hydrogen fuel cell cars
SOLUTION: In this test method, baked and densified stability values (δpv) of pellet are obtained eliminating the effects of reduction of pellet in heating test in dry hydrogen atmosphere by utilizing the relation between the ratio (O/M), the number of oxygen atoms to the number of metal ...
SHE ORP values are comparable to a quantity called Eh, which describes the theoretical ORP of the solution and has the same scale as SHE ORP measurements. The SHE requires bubbling hydrogen gas through a strong acid solution, so it is not practical for routine laboratory or field use. This ...
pH Stands for potential of Hydrogen. And there are two answers as to what it is. The short and simple one. And the long and slightly more complex one. Let’s start with the simple answer: pH is a measurement used to determine whether the water in your aquarium is acidic or alkaline....
Organic solventslike methanol or acetone have a dehydrogenating effect and precipitate proteins, thereby fixing them in their cellular context. But remember that soluble molecules and many lipid components are lost in the process. Frequently, a combination of methanol and acetone is used, because alt...
We've known how important molecular hydrogen has been for life as we know it for a very long time, but it is only recently we have discovered how critical it is for our health. H2plays a key role in the metabolism of cells throughout our bodies, from the heart to the liver to our...
to Southern California, where it is slated to carry riders on San Bernardino County’s Arrow commuter rail service before the end of the year. In the insular world of railroading, this hydrogen-powered train is a Rorschach test. To some, it represents the future of rail transportation. To ...
The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form ...
Extreme H’s car is the first hydrogen-powered racing car to pass FIA crash testing ahead of the series’ launch in 2025, bringing new eyes to hydrogen fuel
