The electron soon attaches itself to another molecule, making a negatively charged ion.
The theory is that when a muon encounters a gas molecule, it can knock off an electron, leaving a positively charged ion in its wake.
If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).
Every time the enzyme connects two bases--an A to a T or a C to a G--an electrically charged ion is released and detected by sensors on the machine.
The Chevy Volt is driven by electric motors powered by lithium-ion batteries that are charged by plugging the vehicle into a standard 110-volt socket.
Their goal is to develop a way of altering the course of an asteroid using an ion rocket, which pushes electrically charged atoms out of the back.
ECONOMIST: A large asteroid sweeps by Earth. Where are the others?
Ion channels sit in a cell's outer membrane and let electrically charged atoms (ions, as they are known in chemical jargon) in and out of the cell.
The system allows a 1.6kWh lithium-ion battery pack, mounted behind the seats for weight distribution reasons, to be charged through a rear axle electro-hydraulic brake energy regeneration system.
In the brain, the signals travelling through the synapses rely on action potential, which is the electrical energy created by the difference in concentrations of charged atoms (ions) on the inside and outside of neuron, which move back and forth through ion channels.
FORBES: MIT Scientists Develop A Chip That Mimics Brain Synapses
Battery regeneration: Whenever the driver releases the accelerator pedal or applies the brakes, and the battery is insufficiently charged, the two electric motors act as generators and feed energy recovered from the brakes into the lithium-ion battery.
