Sentences with phrase «where moving electrons»

Quantum theory predicts that in a two - dimensional electron system, where moving electrons are confined to one plane, under a strong magnetic field electrons also will be restricted to climbing only one step of the energy level ladder at a time.

Like CGL71, these clusters are critical for the first stage of photosynthesis, where they move electrons in order to create the energy molecules.

Not exact matches

Do you know where an electron goes when it moves from one side of an atom to the other?

As Jaramillo put it: «Chemistry is all about where electrons want to go, and catalysis is about getting those electrons to move to make and break chemical bonds.»

Some of that current is lost, however, as moving electrons from the emitter drop into «holes» — places in the base where electrons are missing — releasing energy in the process.

Intrigued by the molecular details of how enzymes worked, he next joined the lab of Michael Toney, where he set out to understand how electrons and protons move during catalysis by analyzing how mutations in the enzyme's functional site affected the reaction mechanism.

For example, turn on your digital camera to snap a picture of the setting sun and photons flying in through the lens make electrons move out from semiconductors located where the film would be in conventional cameras.

Much like in an old tube television where a beam of electrons moves over a phosphor screen to create images, the new microscopy technique works by scanning a beam of electrons over a sample that has been coated with specially engineered quantum dots.

Much like in an old tube television where a beam of electrons moves over a phosphor screen to create images, the new technique works by scanning a beam of electrons over a sample that has been coated with the quantum dots.

The energy given off then catapults a second electron from the WSe2 into the MoSe2, where both electrons become free to move and generate electricity.

Step edges on topological crystalline insulators may lead to electrically conducting pathways where electrons with opposite spin spin move in converse directions — any U-turn is prohibited.

Instead, our current knowledge of materials is derived from a simplified perspective where electrons in solids are described in terms of special non-interacting particles, called quasiparticles, that move in the effective field created by charged entities called ions and electrons.

Semiconductors such as silicon and gallium arsenide have a «bandgap» between the «valence band» — the energy levels where electrons normally reside — and the higher - energy «conduction band» in which electrons are free to move.

To continue this work, he moved to the Walz lab as a post-doctoral fellow, where he completed the first atomic resolution structure of a mammalian membrane protein, aquaporin - 0, using electron microscopy.

Hawking radiation is based on the well established fact of quantuum tunneling where a particle may disappear at one point in space and reappear at another point without enough energy to have moved across a barrier from point A to point B. Flash memory chips work by quantuum tunneling where an electron is raised to an energy level just short of being able to cross a barrier into a holding pen.

Seems yes, but it can only occur where hit by a fast enough moving molecule that adds the right additional energy to put it into its respective continuum listed above or exactly at one of the strong spectrum lines, all by electron interaction.

There are real configurations of matter (electrons) where the existence of actual photons (moving energy) that do not even exist (the probability is zero) even though your logical mind says that surely it must exist, not so.
