Sentences with phrase «between hydrogen atoms»

The extremely high temperatures — hundreds of millions of degrees Celsius — cause fusion to occur between hydrogen atoms in the plasma, releasing tons of energy.

Such interactions are dependent on chemical bonds between hydrogen atoms.

Not exact matches

There are basically two types of lines, those produced by collisions between the atoms or ions and the electrons in the surrounding gas, which are called collision lines, and which are very bright for elements such as oxygen, nitrogen and neon, and lines which are produced when ions capture free electrons, which are called recombination lines, and which are bright only for those gases with the highest abundances in the interstellar medium: hydrogen and helium.

After all, particle accelerator searches over the last two decades had narrowed the range of possible masses for the Higgs; if it existed at all, it had to weigh in at between 114 billion and 143 billion electron volts or GeV (1 GeV is slightly more than the mass of a hydrogen atom).

Like water, it is held together by the powerful bonds between hydrogen and oxygen atoms, so ethanol can not travel through most petroleum pipelines.

Although the gravitational waves are incredibly weak — only enough to warp the distance between Earth and the Sun by the width of a hydrogen atom — LIGO's instruments are extremely sensitive.

At this temperature, the pressure in the reactor reaches 34 atmospheres, helping to break down the bonds between the hydrogen and carbon atoms in the polymer chains.

The zirconium sapped the loyalty of the electrons bonding the nitrogen pairs, weakening the link between the two atoms and letting hydrogen weasel in and latch onto the nitrogen.

He has spent his career focused on just one bond, a link between a carbon and a hydrogen atom in a molecule of methane, the main component of natural gas.

But its intended partner, the fluorine atom, is almost always hidden behind an argon atom, so the hydrogen has to form a linear molecule with argon in between: HArF.

Of the two types of atom, oxygen has more pull on the electrons that they share to form the bonds between them, so the oxygen becomes slightly negatively charged and the hydrogens slightly positive.

Scientists from Tomsk Polytechnic University together with their colleagues from USA and Japan have proposed a novel way to address the most important and fundamental challenge of organic chemistry, i.e. breaking a bond between carbon and hydrogen atoms to form new organic substances.

Relying on a technique called infrared spectroscopy to explore the bonds between atoms, the researchers noticed it attaching to positive hydrogen atoms.

Experiments with this DNA origami positioning device showed that it could be capable of precisely placing molecules, adjusting the distance between them in steps as small as the radius of a hydrogen atom.

It turns out that the answer lies in the interaction between the bonds that hold the atoms in the water molecule together and the much weaker bonds, known as hydrogen bonds, that are the glue holding groups of water molecules together.

The link between energy and water is not always apparent, but the two are as intertwined as the hydrogen and oxygen atoms in a bottle of Evian.

It's called non-molecular ice, because the water molecule is broken apart and the hydrogen atoms are shared between neighboring oxygens.

The researchers discovered that the unique manner in which the platinum and nickel atoms arrange themselves on the surfaces of these particles serves to optimally accelerate the chemical reaction between hydrogen and oxygen to form water.

Recently, a team from Pacific Northwest National Laboratory determined that the key difference between small and large metal particles was their ability to provide active hydrogen atoms.

The polymer and the agent form hydrogen bonds, weak electrostatic connections between polymer's hydrogen and an agent's oxygen atom.

Digging further, they found that the larger particles provided abundant highly active atomic hydrogen atoms, so the key difference between small and large metal particles was their ability to provide hydrogen.

The space between galaxies is a cold and dark place filled only with a filamentous haze of hydrogen atoms left over from the Big Bang.

The presence of the Lyman - alpha line was unexpected: while it is frequently detected in galaxies closer to Earth, the team thought that EGSY8p7's emission line would have been absorbed when the universe was formed by the hydrogen atoms believed to inhabit the space between galaxies.

Fatty acids can be put into three categories based on the molecular length of carbon atoms connected to hydrogen atoms: short - chain that have less than 6 carbon atoms, medium - chain that have between 6 - 12 carbon atoms and long - chain that have between 13 - 21 carbon atoms.

Saturated fat is fat that consists of triglycerides containing only saturated fatty acids; they have no double bonds between the individual carbon atoms of the fatty acid chain — which are fully saturated with hydrogen atoms.

There are no double bonds between the carbon atoms; they're fully saturated with hydrogen atoms.

For example, the hydrogen bonding interaction between the phenolic — OH and the o - methoxy groups in curcumin influences the O - H bond energy and H atom abstraction by free radicals, thus making it a better scavenger of free radicals compared to other curcuminoids such as BDMC.

MONOUNSATURATED FATTY ACIDS are chains of carbon atoms that have one double bond between two carbons and therefore lack two hydrogens.

But when their temperature is lowered and they form a water molecule, the symmetry of the individual atoms is broken as they form a molecule with 105 degrees between the hydrogen - oxygen bonds.
