Sentence examples for particles that when from inspiring English sources

The IONOSPHERE is a shell of electrons and other highly charged atoms and molecules in the upper atmosphere, and it is the intense collision of those particles that, when carried on the solar winds, causes the auroras that we know as the Northern Lights.

A team of Swedish scientists have created paper embedded with metallic particles that, when touched, complete a circuit which produces a recorded sound.

In 2004, for example, researchers designed nanosized particles that, when placed in solution containing hydrogen peroxide, generate hydroxide ions that create a small electric field around the particles; because the particles themselves are charged, they respond to that field and are pulled through the solution.

An alternative to the resample-move filter in Section 3.2 is to use the current observation to preselect at instant a set of particles that, when propagated to instant according to the system dynamics, is more likely to generate samples with high likelihood.

The recombinant vehicle condensed pTRAIL DNA into nanoscale particles that, when exposed to ZR-75-1 breast cancer cells, evoked impressive cell kill (up to 62%).

In addition to endotoxin, allergens, microbial pathogens, bacterial toxins, fungal spores, and mycotoxins can attach to dust particles that, when inhaled, have the potential to cause local and systemic inflammatory reactions.

The Large Hadron Collider, just outside Geneva, Switzerland, was built to accelerate the subatomic particles called protons to energies of seven trillion electron volts and then smash them together in search of forces and particles that existed when the universe was less than a trillionth of a second old.

The collider, which started operations in 2010, is designed to fire protons at each other with a combined energy of 14 trillion electron volts and search the debris from collisions for clues to forces and particles that prevailed when the universe was only a trillionth of a second old.

The boric acid is needed to sop up excess neutrons, the subatomic particles that are released when uranium is split, and which sustain the chain reaction.

The disease control agency regards environmental microbiology as one of its strengths, Dr. Gerberding said, but it soon learned that the discipline had a long way to go when it came to anthrax -- in particular, sampling the air for spores, disinfecting an area and monitoring it for spores and particles that might escape when envelopes are put under mechanical pressure.

Nuclear experiments performed here, and the production of isotopes for scientific and medical research, which is a common use of research reactors elsewhere, require a high density of neutrons, the subatomic particles that are released when one atom is split, and which go on to split other atoms in a chain reaction.
