Electrically controlled terahertz (THz) beamforming antennas are essential for various applications such as wireless communications, security checks, and radar to improve coverage information capacity. The emerging programmable metasurface provides a flexible, cost-effective platform THz beam steering. However, scaling arrays achieve high-gain steering faces several technical challenges. Here, we propose pixelated liquid crystal with crossbar structure, thereby increasing the array scale...
An intermolecular 1,2-diacylation of alkenes is disclosed via cooperative N-heterocyclic carbene and photoredox catalysis under the mediation PPh3 Cs2CO3. This protocol provides a practical approach for construction 1,4-dicarbonyl compounds toward novel diketone pharmaceutical derivatives. Furthermore, regioselective dicarbonyl can be synthesized by adding acyl azolium salt. Mechanistic investigations suggest that process was critical radical/radical cross coupling ketyl radicals with...
Selective reduction of nitroaromatics to the corresponding amines generally requires complex conditions, involving pressurized hydrogen, higher temperatures, or organic acids. In this work, we successfully prepared a series porphyrin-based MOF photocatalysts (Pd-PMOFs, In-PMOFs, and In/Pd-PMOFs) via facile solvothermal method for efficient selective anilines with deionized water as hydrogen donor. Being new structured material (monoclinic, C52H40InN6O8Pd), on account abundant pore channels,...
Abstract Green synthesis of stable metal‐organic frameworks (MOFs) with permanent and highly ordered porosity at room temperature without needing toxic harmful solvents long‐term high‐temperature reactions is crucial for sustainable production. Herein, a rapid environmentally friendly strategy reported to synthesize the complex topological bismuth‐based‐MOFs (Bi‐MOFs), [Bi 9 (C H 3 O 6 ) (H 2 O) ] (denoted CAU‐17), in water under ambient conditions by surfactant‐mediated sonochemical...

The meaningful and rational engineering of porphyrin-based catalysts with multimetallic active sites is very attractive toward photocatalytic hydrogen generation from water decomposition. Herein, three metal organic frameworks (MOFs) based on meso-tetrakis(4-carboxylphenyl)porphyrin (TCPP) were successfully constructed under solvothermal conditions. As a novel architectured photocatalyst (triclinic, C48H29N4O10PdYb), Pd/Yb-PMOF manifested diverse sites, suitable bandgap positions, prominent...
Mode-locked fiber lasers are an ideal platform for ultrafast nonlinear physics study, and they have shown many intriguing, yet not fully understood, phenomena such as the optical rogue waves (ORWs) noise-like pulses (NLPs). However, one of major obstacles in study laser dynamics is lack practical measurement techniques round-trip tracking, single-shot, real-time observation time domain at sub-picosecond (ps) resolution. Here we demonstrate automatically synchronized characterization NLPs...
