For years, organic electro-optic polymers have held the promise of vastly improving technologies such as communications, data processing and image displays. Now it appears scientists are on the verge of breakthroughs that will bring dramatic progress in materials, as well as the devices in which they are used, setting the stage for a virtual revolution.
Simply put, electro-optic polymers are being used to make devices that take information that typically has been transmitted electronically and transfer it to optical systems that use light. The latest developments will affect not just how much information can be sent at one time but also the power required to transmit the information.
The newest materials have made possible something called wavelength division multiplexing, a process that can separate a beam of light into perhaps 100 different colors and impose as much as 50 gigabits of information on each color. At that rate, a beam of light could transmit 5 terabits — or about 625 gigabytes — of data per second, and could move data equivalent to what is in the Library of Congress in about 30 seconds.

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.
