Spectral dynamics of shift current in ferroelectric semiconductor SbSI [Applied Physical Sciences]
Photoexcitation in solids brings about transitions of electrons/holes between different electronic bands. If the solid lacks an inversion symmetry, these electronic transitions support spontaneous photocurrent due to the geometric phase of the constituting electronic bands: the Berry connection. This photocurrent, termed shift current, is expected to emerge on the timescale…

Small molecule ISRIB suppresses the integrated stress response within a defined window of activation [Cell Biology]
Activation of the integrated stress response (ISR) by a variety of stresses triggers phosphorylation of the α-subunit of translation initiation factor eIF2.
