New process produces ordered semiconductor material at room temperature
Graphical summary. Credit: Nature Synthesis (2025). DOI: 10.1038/s44160-024-00717-z Scientists at the University of Twente have developed a method to create highly ordered semiconductor materials at room temperature. The UT study was published today in the journal Nature Synthesis. This breakthrough could improve the efficiency of optoelectronics by controlling the crystal structure and reducing the number of defects at the nanoscale.…

AI technology produces clear images of thick biological samples without additional hardware.
Concepts and simulations demonstrating deep learning-based aberration correction. Credit: Nature Communications (2025). DOI: 10.1038/s41467-024-55267-x Depth degradation is a problem that biologists are familiar with. The deeper you examine the sample, the blurrier the image becomes. C. elegans embryos and pieces of tissue are only tens of microns thick, but when the instrument peeks past the top layer, light bending causes…

Twisted Edison: A nanoscale curled filament produces light waves that rotate as they travel.
The light bulb’s Edison-style filament is twisted on a microscale, similar to the strands Jun Lu holds next to the demonstration. When the length of each twist matches the wavelength of the light emitted by the filament, the light waves rotate as they travel through space. Credit: Brenda Ahearn/Michigan Engineering Bright, twisted light can be produced using technology similar to…

Researchers develop a laser that produces the most powerful ultrashort laser pulses ever
Overall system overview: A laser appears in the center of the image, and in the foreground are lenses and mirrors that reflect and redirect the laser beam. Credit: Moritz Seidel / ETH Zurich The word laser usually conjures up images of a continuous, intensely focused beam of light. Lasers that produce such light are actually quite common and useful. However,…

Deep Design Produces ‘Butterfly’ Phase Mask for Light Sheet Fluorescence Microscopy
(A) With a conventional Gaussian beam, the illumination beam spreads at its edges due to diffraction. (B) Joint optimization scheme, where the network predicts the position of the beads in the focal plane. The deep learning network and the input phase mask are updated simultaneously based on a loss function. Credit: Chen Li et al. Researchers have presented a solution…
