New work repurposing one of the oldest known reagents for amyloid looks to help provide a clearer picture of how fibrils come together.
Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of tools and technology used by gravitational wave scientists. Physicists at Louisiana State University measure quantum "back action" in the audio band at room temperature.
A research group led by professor PAN Jianwei and LU Chaoyang of University of Science and Technology of China successfully designed the largest planar code platform at present using photons, and demonstrated path-independent property in optical system for the first time.
For many years we have been hearing that holographic technology is one step closer to realizing Star Trek's famous Holodeck, a virtual reality stage that simulates any object in 3D as if they are real. Sadly, 3D holographic projection has never been realized. A team of scientists from Bilkent University, Turkey, again raised our hopes on Holodeck realization by showing the first realistic 3D holograms that can be viewed from any angle. Dr. Ghaith Makey, the lead author of the paper appearing in the April 2019 issue of Nature Photonics today, says 'Our technique can work in realtime, and will surely pave the way to dynamic 3D video holography. Soon, it may be possible to create a simple version of a Holodeck'.
Ryerson University Physicist Dr. Michael Kolios, his former graduate student Dr. Michael Moore, and collaborator zebrafish model expert Dr. Xiao-Yan Wen developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.
University of Maryland physicists have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce an electron avalanche breakdown near the material, the new technique can detect shielded material from a distance -- improving upon current technologies that require close proximity to radioactive material. With additional engineering, the method could be scaled up to scan shipping containers at ports of entry, providing a powerful new tool for security applications.
A Rice University-led study discovers a mechanism by which molecules affect the plasmonic response of gold nanorods. The mechanism could be used to enhance applications like catalysis that involve plasmon-driven chemistry.
Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge. The techniques developed so far have produced rather poor results. However, University of Groningen scientists, led by Professor of Photophysics and Optoelectronics Maria Antonietta Loi, have now cracked it -- using a blade and a dipping solution. The results were published in the journal Nanoscale on March 15, 2019.
Nanowire gurus at the National Institute of Standards and Technology have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable LEDs based on a simpler shell design.
Researchers have developed a microscope specifically for imaging large groups of interacting cells in their natural environments. The instrument provides scientists with a new tool for imaging neurons in living animals and could provide an unprecedented view into how large networks of neurons interact during various behaviors.
