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.

This radiation strips electrons from atoms within the gas, which eventually recombine with other atoms and release light.

In the case of UED, an electron beam shines through a gas of iodine molecules, with the distance between the two iodine nuclei in each molecule defining the double slit, and hits a detector instead of a screen.

These outbound electrons don't reach peak speeds until they are a few thousand kilometers high, where the atmosphere is so thin that the particles rarely collide with gases and therefore don't glow, says FAST project scientist Robert Pfaff Jr. of NASA's Goddard Space Flight Center in Greenbelt, Maryland.

These high - speed electrons then collide with and heat nearby gas.

A second electrode and a different catalyst will be needed to combine those electrons with the hydrogen ion to make hydrogen gas.

Hydrogen atoms are formed in such devices only when electrons flow into a fluid where they can combine with hydrogen ions; those atoms in turn combine with each other to create hydrogen gas.

Sensors made with atomically thin layers of MoS2 revealed better selectivity to certain gases owing to the electron energy band gap in this material, which resulted in strong suppression of electrical current upon exposure to some of the gases.

When charged particles from the inner solar system reach the boundary of the heliosphere, they sometimes undergo a series of charge exchanges with neutral gas atoms from the interstellar medium, dropping and regaining electrons as they travel through this vast boundary region.

The hiss occurs throughout the plasmasphere (the zone thousands of miles above the earth that teems with ionized gases), removing the plasmasphere's high - energy electrons and tempering their lethal power.

Sketch of the nebula formed by a wind of electrons and positrons coming from the pulsar, and the interaction with interstellar gas.

Just as an atom with a full outer electron shell is a peculiarly unreactive noble gas, an outer shell with the right number of protons and neutrons makes a nucleus magically stable.

An electron in the current might collide with a molecule of gas and break its chemical bond, giving rise to something new.

Writing today (Feb. 5, 2018) in the journal Nature Materials, Eom and his collaborators provided evidence of a hole gas coexisting with the electron gas.

Gases (such as air, which has an equal number of positive and negative charges) become plasma when energy (such as heat or electricity) causes some of the gas's atoms to lose their negatively charged electrons, creating atoms with a positive charge, or positive ions, surrounded by the newly detached electrons.

Furthermore, if the electrons react only with water at the cathode, they generate hydrogen gas — which contains enough energy to fuel the extra voltage requirements.

To address the terahertz gap, the team created a hybrid semiconductor: a layer of thick conducting material paired with two thin, two - dimensional crystalline layers made from graphene, silicene (a graphene - like material made from silicon instead of carbon), or a two - dimensional electron gas.

As gas flies away from the detonated star, it reacts with the interstellar medium, knocking away closely held electrons from even heavy elements.

The Universe is filled with plasma, a charged gas consisting of ions and electrons.

With solids, liquids or gases, symmetry relates to the behavior of the spins of the atoms and electrons.

As a quasar's black hole sucks in gas from surrounding space, the gas collides with the edge of its dark - matter halo and forms a shock wave, which heats the gas suddenly and strips off electrons to form electrically charged ions.

The gases flow in currents through the sun, carrying electrons with them.

Plasma is a hot, energetic gas where the atoms are stripped of their electrons, creating an electrically active gas with unique magnetic properties.

But unlike old Jaguars with two gas caps, one is for liquid fuel, the other for electrons.

Hydrogen is the simplest of gases consisting of one electron and a nucleus with one neutron and one proton.

Compare with electronic transition absorption of visible light by the electrons of the molecules of nitrogen and oxygen in the atmosphere, the real gas Air, which is what gives us our blue sky, reflection / scattering.

At specific IR frequencies greenhouse gases resonate with outgoing photons resulting in vibrations, rotations, translations and electron orbit excitations.

He mixed a few atmospheric gases, and then bombarded them with UV rays and heavy electrons.

But as they're replaced with, for instance, nimbler gas plants, that will ease the daytime traffic jam of electrons caused by solar.
