Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles.
which particles have no energy at all, and higher temperatures correspond to higher average energies. However, by the 1950s, physicists working with more exotic systems began to realise that this isn't always true:
Technically, you read off the temperature of a system from a graph that plots the probabilities of its particles being found with certain energies.
Normally, most particles have average or near-average energies, with only a few particles zipping around at higher energies.
In theory, if the situation is reversed, with more particles having higher, rather than lower energies, the plot would flip over

that delivers energy more often and in smaller chunks than traditional adapters, ultimately wasting less energy.
which transfers energy from the adapter to the battery run 1, 000 times faster. f you can increase that switching frequency,
you can reduce the amount of energy that you have to store temporarily in the inductors and capacitors
But each switch cycle burns energy as heat. Switching 1, 000 times faster in a typical converter,
therefore, means 1, 000 times more energy wasted. So the circuit uses resonance techniques (modifying how energy oscillates between inductors
and capacitors) to minimize energy loss, meaning the switches turn on and off more efficiently at higher frequencies.

much of the incoming energy is given off as waste heat rather than electrical current. In a few materials,
however, extra energy produces extra electrons behavior that could significantly increase solar-cell efficiency. An MIT team has identified now the mechanism by
In most photovoltaic (PV) materials, a photon (a packet of sunlight) delivers energy that excites a molecule,
But when high-energy photons provide more than enough energy, the molecule still releases just one electron plus waste heat.
Instead, they generate more than one electron per high-energy photon. That phenomenon known as singlet exciton fission was identified first in the 1960s.
In 2013, they reported making the first solar cell that gives off extra electrons from high-energy visible light,
When excess energy is available in these materials, an electron in an excited molecule swaps places with an electron in an unexcited molecule nearby.
The excited electron brings some energy along and leaves some behind, so that both molecules give off electrons.
Indeed, a far more important factor is choosing a material that has the right inherent energy levels.

#Excitons observed in action for the first time A quasiparticle called an exciton responsible for the transfer of energy within devices such as solar cells LEDS
The particles determine how energy moves at the nanoscale. The efficiency of devices such as photovoltaics and LEDS depends on how well excitons move within the material he adds.
but it can carry energy. For example in a solar cell an incoming photon may strike an electron kicking it to a higher energy level.
but the boosted energy gets passed along from one to another. While it was previously possible to determine how fast on average excitons could move between two points we really didn t have any information about how they got there Akselrod says.
which combines optical microscopy with the use of particular organic compounds that make the energy of excitons visible we can directly say what kind of behavior the excitons were moving around with.
so that energy is lost not to leakage; for other uses such as solar cells it is essential to minimize the trapping.
We showed how energy flow is impeded by disorder which is the defining characteristic of most materials for low-cost solar cells
Plants absorb energy from photons and this energy is transferred by excitons to areas where it can be stored in chemical form for later use in supporting the plant s metabolism.
The new method might provide an additional tool for studying some aspects of this process the team says.
