Abstract The alkoxyl radical is an essential and prevalent reactive intermediate for chemical biological studies. Here we report the first donor–acceptor complex‐enabled generation under metal‐free reaction conditions induced by visible light. Hantzsch ester forms key complex with N ‐alkoxyl derivatives, which elucidated a series of spectrometry mechanistic experiments. Selective C(sp 3 )‐C(sp ) bond cleavage allylation/alkenylation demonstrated time using this photocatalyst‐free approach...
Optical mirror misalignments, which are caused by assembly mistakes and changes in the surrounding environment (such as gravity, temperature, atmosphere), degrade system’s imaging performance. Therefore, active misalignment correction is essential for ensuring image quality of off-axis telescope. In this paper, a novel method without wavefront sensors proposed. The point spread functions (PSFs) system analytically related to optical misalignments. On basis, fully connected neural network...
Battery thermal management is of great significance for increasing the safety and prolonging service life electric vehicle battery pack. In this paper, property pouch Lithium-ion module cooled by PCMs (Phase Change Materials) was investigated. The three-dimensional models modules consisted different thickness batteries were established to study effects space between adjacent batteries, melting point conductivity on cooling performance. results showed that Tmax (maximum temperature) ΔTmax...
We propose a compact, ultrabroadband and temperature-insensitive adiabatic directional coupler based on rib silicon waveguide-enabling arbitrary splitting ratios. Simulation results show that the device can achieve ratios from 1400 to 1600 nm, equal 50%:50%, 60%:40%, 70%:30%, 80%:20%, 90%:10% for fundamental transverse electric mode. The designed has an excess loss of less than 0.19 dB operational waveband. Furthermore, proposed shows great robustness fabrication imperfection, with waveguide...
The standby battery for outdoor base station could not function properly at cold environment a long time. In order to improve its performance and lengthen life time, it was necessary heat the keep warm. This dissertation presented heating preservation method of 48 V Lead-acid pack based on plate phase change materials environment. Then, thermal management performances this were simulated. results showed that uniformity temperature field increased process lengthened effectively. And kept good...
Tm,Ho:CaGdAlO4 disordered crystal with ultra-broad emission spectra around 2 μm was achieved successfully by modulating the intensity of Tm/Ho co-doped ions to same level. The polarized absorption and spectra, fluorescence lifetime were regularly investigated, showing ultra-wide (264 nm full width at half maxima) near μm. results indicate that a broader has potential generate ultrashort pulse laser. Simultaneously, energy transfer spectral broadening characteristics in crystals can be deeply...
Dispersed fringe sensor (DFS) is an important phasing of next-generation optical astronomical telescopes. The measurement errors induced by the noise three piston estimation methods for DFS including least-squared fitting (LSF) method, frequency peak location (FPL) method and main position (MPP) are analyzed theoretically validated experimentally in this paper. experimental results coincide well with theoretical analyses. MPP, FPL, LSF used respectively when operates broadband light (central...
This passage puts forward a kind of LLCL inverter which is based on the proportional feedback integral(PFI) control so as satisfy request grid-current outputed by renewable energy generation system. The builds topological graph grid-connected and makes an analysis principle linear superposition aims to reveal essence problem steady-state error that exists in integral control. We use filter method passive damping solve resonant peak. make simulation grid system with software named...
