Wavefront Line‐Scan Imaging Via a Single‐Pixel Detector
Advanced Science, EarlyView.We propose and demonstrate a wavefront line‐scan imaging paradigm that integrates 1D spatial light modulation with single‐pixel detection. Benefiting from 1D modulation, not only is the imaging speed improved, but also the storage of modulation patterns is reduced by several orders of magnitude.

Laser terahertz emission microscopy
Comptes Rendus. Physique, 2008 Laser terahertz (THz) emission microscopy (LTEM) is reviewed. Femtosecond lasers can excite THz waves in various electronic materials due to ultrafast current modulation. The current modulation is realized by the acceleration or deceleration of photo-excited carriers, and thus LTEM visualizes the dynamic photo-response of ...

Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons
Angewandte Chemie, EarlyView.An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.

Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide
Advanced Science, EarlyView.ABSTRACT Electron acceleration by a high‐power Laguerre‐Gaussian pulse in a micro‐plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall are extracted into the vacuum core and accelerated by the longitudinal field of the waveguide mode.
