Zajfman and colleagues injected around 10 000 argon ions into an ‘electrostatic trap’ – a tube 40 cm long with ring-shaped electrodes around both ends. These electrodes act as ‘mirrors’, and their ...

THE emission of secondary electrons from metals by positive ions has been studied by a number of workers 1, and it has been established that the efficiency of this process depends upon the work ...

Utilizing Secondary Ion Mass Spectrometry (SIMS) for in-line metrology is a newly emerging method of process control that requires contamination-free measurements, enabling SIMS on product wafers.

They power tiny phones and two-tonne electric cars. They form the guts of a growing number of grid-storage systems that smooth the flow of electricity from wind and solar power stations. Without them, ...

The race is on to make lithium-ion batteries safer, to increase the amount of energy that can be drawn out of these devices, and to reduce the time it takes to charge them up again. Transistors and ...

Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...
