Just as matter can be converted into energy, so too can energy become matter. That’s what five-dozen Jefferson Lab researchers were counting on for an experiment in Hall A
Albert Einstein figured it out by 1905, as he was formulating his special theory of relativity: while you can’t exactly get something from nothing, you can come close. His famous formula, E=MC2, works both ways. Just as matter can be converted into energy, so too can energy become matter.
That’s just what five dozen researchers were counting on with a Jefferson Lab experiment in Hall A that used the Lab’s electron beam and a liquid hydrogen target to bring to life an unusual particle known as a kaon. The kaon’s unique structure could prove of great help to cosmologists, who should be able to use the results of experiments like the Hall A effort to develop structural models of stellar objects made up of exotic, or "strange" matter, matter that includes kaons as part of their own subatomic architectures. Preliminary findings indicate that kaon production results from the interactions of the particles of light known as photons. The photons create more than just kaons, however. They also produce other particles, known as lambda and sigma, with their own distinctive quark structure. All arise from a constantly churning sea of "virtual" particles that can’t exist until bumped by a jolt of energy such as that provided by the Lab’s accelerator.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
