Published Tiny displacements, giant changes in optical properties
(via sciencedaily.com) Original source Researchers reveal a new pathway for designing optical materials using the degree of atomic disorder. The researchers anticipate developing crystals that enable advanced infrared imaging in low light conditions, or to enhance medical imaging devices.
Published Researchers 'unzip' 2D materials with lasers
(via sciencedaily.com) Original source Researchers used commercially available tabletop lasers to create tiny, atomically sharp nanostructures in samples of a layered 2D material called hexagonal Boron Nitride (hBN). The new nanopatterning technique is a simple way to modify materials with light--and it doesn't involve an expensive and resource-intensive clean room.
Published Turbid waters keep the coast healthy
(via sciencedaily.com) Original source To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.
Published AI to make crop production more sustainable
(via sciencedaily.com) Original source Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. Researchers are working on driving forward the smart digitalization of agriculture and have now published a list of the research questions that will need to be tackled as a priority in the future.
Published New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
(via sciencedaily.com) Original source Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Sister cities can help communities better navigate the climate crisis
(via sciencedaily.com) Original source Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
Published Tweaking isotopes sheds light on promising approach to engineer semiconductors
(via sciencedaily.com) Original source Scientists have demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors.
Published Climate change amplifies severity of combined wind-rain extremes over the UK and Ireland
(via sciencedaily.com) Original source Climate change will cause an increase in extreme winter storms combining strong winds and heavy rainfall over the UK and Ireland, new research has shown.
Published Physicists arrange atoms in extremely close proximity
(via sciencedaily.com) Original source Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.
Published Path to easier recycling of solar modules
(via sciencedaily.com) Original source The use of femtosecond lasers to form glass-to-glass welds for solar modules would make the panels easier to recycle, according to a proof-of-concept study.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published New sensor detects errors in MRI scans
(via sciencedaily.com) Original source A new prototype sensor is capable of detecting errors in MRI scans using laser light and gas. The new sensor can thereby do what is impossible for current electrical sensors -- and hopefully pave the way for MRI scans that are better, cheaper and faster.
Published Unveiling a polarized world -- in a single shot
(via sciencedaily.com) Original source Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
Published This highly reflective black paint makes objects more visible to autonomous cars
(via sciencedaily.com) Original source Driving at night might be a scary challenge for a new driver, but with hours of practice it soon becomes second nature. For self-driving cars, however, practice may not be enough because the lidar sensors that often act as these vehicles' 'eyes' have difficulty detecting dark-colored objects. New research describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.
Published New technology makes 3D microscopes easier to use, less expensive to manufacture
(via sciencedaily.com) Original source 3D microscopes are used in applications from the life sciences to semiconductor manufacturing. Now engineers are developing patented and patent-pending innovations making them work faster to capture even more 3D images and less expensive to manufacture.
Published Laser imaging could offer early detection for at-risk artwork
(via sciencedaily.com) Original source A bright yellow pigment favored a century ago by Impressionists such as Matisse and Van Gogh is losing its luster. Researchers have developed a laser imaging technique that can detect the first tiny signs of the pigment's breakdown before they're visible to the eye. The work could help art conservators take earlier steps to make the color last.
Published Details of hurricane Ian's aftermath captured with new remote sensing method
(via sciencedaily.com) Original source Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.
