A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.
Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...
Researchers in China developed a novel two dimensional (2D) seeding agent to regulate crystallization in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the ...
