Scientists from the universities of Bristol and Cambridge have found a way to create polymeric semiconductor nanostructures that absorb light and transport its energy further than previously observed.
Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research.
Pioneering research has given a fascinating new insight into why the Pacific Trade Winds have seen “unprecedented strengthening” over recent decades.
Researchers at The University of Texas at Arlington have found a correlation between a strong immune response in diseased corals and a lower expression of genes associated with growth and reproduction.
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.
Laser pulse compression technology invented in the late 1980s developed high-power short-pulse laser techniques, enhancing laser intensity 10-million-fold in a quarter of a century.
MKS Instruments, Inc., a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® PD300-MS microscope slide power meter for accurate measurements of light emitted from fluorescence microscopes. The PD300-MS measures power levels of high numerical aperture (NA) objectives, from 5µW to 1W. A special filter provides low angular dependence, enabling higher accuracy measurements. NIST-traceable calibration allows for measurement of wavelengths from 350nm to 1100nm. The power meter is designed for use with a wide range of light sources in such applications as photoactivation or photobleaching. To accommodate limited space, it has the same footprint as a standard microscope slide. The PD300-MS can be used at the sample plane in air or with water/oil immersion objectives without damage.
It is becoming harder to respond to the demands of the rapidly-growing information society due to failures caused by increased chip temperatures in the ever-more integrated chips used by the latest electronic devices based on semiconductor materials.
As electronic devices and circuits shrink into the nanoscale, the ability to transfer data on a chip, at low power with little energy loss, is becoming a critical challenge. Over the past decade, squeezing light into tiny devices and circuits has been a major goal of nanophotonics researchers.
Scientists at the Department of Energy’s Oak Ridge National Laboratory are the first to successfully simulate an atomic nucleus using a quantum computer. The results, published in Physical Review Letters, demonstrate the ability of quantum systems to compute nuclear physics problems and serve as a benchmark for future calculations.
