This study introduces an X-ray imager that uses TlBr detectors and demonstrates its potential for X-ray imaging applications. Although TlBr detectors are suitable for X-ray imaging applications because of the associated large attenuation coefficients

Retinal prostheses are promising techniques to restore eyesight sense for visually impaired people. However, some conventional retinal prostheses require external cameras, and the eyeball direction is different from the view direction. Moreover, some

We present what we believe to be the demonstration of optical vortex trapping and chiral crystallization of sodium chlorate (NaClO3). In this work, the chirality of NaClO3 crystals is selectively controlled by altering the helicity (helical direction
