Angewandte Chemie International Edition, Volume 65, Issue 10, 2 March 2026.Rapid RASER MRI allows for image acquisition without RF excitation. Instead, a population inversion on the nuclear spins is generated by SABRE hyperpolarization, which allows for self‐excitation through the RASER approach. When the desired transverse magnetization is built‐up, conventional EPI encoding is triggered to record the image.

Directional Loudspeaker Using a Parametric Array [PDF]
, 2006 The theory for sound reproduction of parametric arrays is based on nonlinear acoustics. Due to the nonlinearity of the air, a finite amplitude ultrasound interacts with itself and generates audible secondary waves in the sound beam.

Advanced Materials, Volume 38, Issue 13, 3 March 2026.Reconfigurable ferroelectric photodiodes based on α‐In2Se3 enable analog and polarity‐tunable photoresponsivity through gradual modulation of built‐in fields at dual Schottky junctions. Furthermore, based on the high‐density spatial integration capability, the system adaptively configures its spatial support to prioritize either suppressing ...
