JEMA, the company based in Lasarte in the Basque Country, has recently put into operation the two energy supply plants designed and manufactured for the European EFDA (the European Fusion Development Agreement)-JET nuclear fusion experimental reactor at Culham in the United Kingdom. This reactor is one of the plants on which ITER, the largest research project in the world, has been based.
With this achievement JEMA has carried out more than 2 years of intense work in research, design and construction of equipment which is at the latest available technological cutting edge of what is possible in manufacturing today.
Each supply plant produces 20 million watts (approximately 10% of the energy produced at the power station at the Basque port of Pasaia) using 130,000 volts d.c. power supply at 130 amperes, with high quality and precision specifications: less than 1,000 volts of error; 150 microseconds rising ramp and 7 microseconds falling ramp.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
