An experiment proposed at Griffith University and performed at the University of Science and Technology of China (USTC) has shown that quantum uncertainty can be enforced in a strange, non-local way, even with just a single particle.
The new 6.5 mm wide-angle lens with 17.6 mm image circle, for cameras with 1.1'' sensors, completes the Xenon-Topaz series from Schneider-Kreuznach. With a working distance from 0.3 m to infinity and a maximum angle of view of 114°, this lens fits for various applications where a huge field of view is needed from a near distance as common in security cameras for face recognition.
Light can be used not only to measure materials' properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as the ability to conduct electricity or to store information in its magnetic state.
Decay is relentless in the macroscopic world: broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: new research shows that so-called quasiparticles can decay and reorganize themselves again and are thus become virtually immortal. These are good prospects for the development of durable data memories.
Researchers at the Institute for Integrated Cell-Material Sciences at Kyoto University have made a popular type of dye-sensitized solar cell more efficient by adjusting and updating their structure. Published in the Journal of the American Chemical Society (JACS), the team report a series of adaptations with a power conversion efficiency of 10.7%, the highest yet for this kind of dye-sensitized solar cell, the most efficient solar technology available at present.
A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were able to produce particularly high-energy flashes of radiation in the terahertz range having a sharply defined wavelength (colour).
Midsummer’s new and slimmer energy-producing solar cell roof, ”Midsummer solar roofs”, have been successfully installed on a house in Kivik, in the southern part of Sweden. It is the first installation of the new roof. The roof is a beautifully folded metal roof that is integrated with Midsummer’s thin film solar panels and with a high effect.
To absorb incoming sunlight, plants and certain kinds of bacteria rely on a light-harvesting protein complex containing molecules called chromophores. This complex funnels solar energy to the photosynthetic reaction center, where it is converted into chemical energy for metabolic processes.
A growing number of applications, including smartphone cameras, depend on microlenses to boost performance. A newly developed technology, called laser catapulting, could make it much easier and less expensive to fabricate these miniaturized lenses with customized properties, such as shape or focusing power.
Researchers have developed a new type of graphene electrode for ultra-sensitive and controllable flexible capacitive pressure sensors.
