Enhanced ion acceleration in the ultra-intense laser driven magnetized collisionless shocks by Wen-shuai Zhang, Hong-bo Cai, Liu-lei Wei, Jian-min Tian, Shao-ping Zhu

“…For the interaction of ultra-intense sub-picosecond laser pulses with the near-relativistic critical-density plasma, the longitudinal transport of the laser generated fast electrons are significantly inhibited by the kilo-Tesla (kT) level transverse magnetic field, resulting in a thermal pressure which significantly exceeds the laser radiation pressure in the hot electron accumulation region. As a result, the accumulated plasma expands into the vacuum and leads to acceleration of a supersonic plasma flow in the opposite direction through the rocket effect, which streams into the target and drives a supercritical magnetized collisionless shock. …”

Piezoelectric Effect Enhanced Photocatalytic Activity of Pt/Bi_3.4Gd_0.6Ti₃O₁₂ Plasmonic Photocatalysis by Fengjuan Liang, Shijun Wu, Zhiwu Chen, Zhenya Lu

“…The PtNPs in Pt/BGTO heterojunction can absorb the incident light intensively, and induce the collective oscillation of surface electrons due to the surface plasmon resonance (SPR) effect, thus generating “hot” electron–hole pairs. The internal piezoelectric field produced in BGTO by ultrasonic can promote the separation of SPR-induced “hot” charge carriers and facilitate the production of highly reactive oxidation radicals, thus enhancing Pt/BGTO heterojunction′s photocatalytic activity for oxidizing organic dyes.…”
