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



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.

Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Tweaking isotopes sheds light on promising approach to engineer semiconductors



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 Physicists arrange atoms in extremely close proximity



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



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 New sensor detects errors in MRI scans



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



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



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



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



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 Atomic nucleus excited with laser: a breakthrough after decades



For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
Published Physicists show that light can generate electricity even in translucent materials



Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.
Published Speeding up spectroscopic analysis



Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is the considerable measuring time this technique usually requires, which often leads to lengthy acquisition times spanning minutes to hours. Researchers have now developed a technique to speed up spectroscopic analysis.

Researchers outline how they used a chemical probe to light up interlocking peptides. Their technique will help scientists differentiate synthetic peptides from toxic types found in Alzheimer's disease.
Published AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes



Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.
