Much like the conveyor belt in a production plant, NPL’s electron surf machine delivers electrons one by one in a reliable steady stream at a rate of more than a billion a second. Whilst small streams of electrons can already be produced, until now no one has found a way to deliver them in a controlled fashion at such a high rate.
NPL’s method involves creating oscillating waves of electro-static force which flow like the surf rolling into a beach. A single electron is placed on the crest of each wave and the electro-static waves are then focused in a particular direction or at a particular object.
The applications for the control of so many individual electrons include better new computers and ensuring absolute security for digital communication.
All computer systems rely on a flow of electrical current through microprocessors. In existing computers, thousands of electrons flow in a disorderly manner in and out of each processor. This random motion causes significant heating (just feel the bottom of your laptop) and limits the computer’s efficiency. By controlling individual electrons, exactly the right amount of current can be targeted at the processor at exactly the right time, allowing the computer to undertake more tasks, run more efficiently and cope with more requests at once.
Digital communication relies on the break up of a signal into small pieces, which are transported through wired or wireless communication networks and then pieced together at the recipient’s end. Anyone wishing to eavesdrop needs to remove part of the message in transit to see or hear the information. The new electron surf machine could be used to encode the message into individual tiny light pulses (photons), making it much simpler to identify any which have been ‘removed’ by eavesdroppers, deterring snooping and alerting the sender or recipient that tampering has taken place.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
