Iron melting temperature and phase stability under nuclear-like conditions shed light on Earth’s geodynamics
Laser-driven impact phenomena in iron at high-power laser facilities (HPLF). X-ray absorption spectroscopy (XAS) was used to determine the melting temperature and microstructure of iron at pressures relevant to geosciences. Credit: Jean-Alexis Hernandez, European Synchrotron Radiation Facility. Iron is one of the major elements found in the Earth’s inner core, which is characterized by extremely high temperatures and pressures. Therefore,…

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…
