Abstract Developing lightweight and broadband microwave absorbers for dealing with serious electromagnetic radiation pollution is a great challenge. Here, novel Fe–Co/N-doped carbon/reduced graphene oxide (Fe–Co/NC/rGO) composite hierarchically porous structure was designed synthetized by in situ growth of Fe-doped Co-based metal organic frameworks (Co-MOF) on the sheets cocoon-like rGO followed calcination. The Fe–Co/NC composites are homogeneously distributed rGO. Fe–Co/NC/rGO multiple...
Abstract Most top‐rank organic solar cells (OSCs) are manufactured by the halogenated solvent chloroform, which possesses a narrow processing window due to its low‐boiling point. Herein, based on two high‐boiling solvents, chlorobenzene (CB) and non‐halogenated green ortho‐xylene (OX), preparing active layers with hot solution is put forward enhance performance of OSCs. In situ test morphological characterization clarify that hot‐casting strategy assists in fast synchronous molecular...
As-cast organic solar cells (OSCs) possess tremendous potential for low-cost commercial applications. Herein, five small-molecule acceptors (A1-A5) are designed and synthesized by selectively elaborately extending the alkyl inner side chain flanking on pyrrole motif to prepare efficient as-cast devices. As extension of chain, absorption spectra films gradually blue-shifted from A1 A5 along with slightly uplifted lowest unoccupied molecular orbital energy levels, which is conducive optimizing...
A novel porous cocoon-like reduced graphene oxide (rGO) with high porosity and low density was fabricated by a simple green reduction reaction using ascorbic acid as the reductant in combination freeze-drying process without annealing. The bulk of rGO is only 28.49 mg/cm3, reaches 94.57%. times have an important influence on formation degree rGO. exhibits excellent microwave-absorbing property mass filling ratio 7.0 wt %; its minimum reflection loss (RL) −29.05 dB at 15.96 GHz sample...
This paper studies the dynamic behaviors of weak-grid-tied VSCs with simplified transfer functions, which provides an accurate stability analysis and useful indications for tuning system parameters. A reduced-order multi-input multi-output (MIMO) function that contains four single-input single-output (SISO) functions VSC is first presented. It found SISO share same equivalent open-loop function, i.e., conclusion. The Bode plots show inner current loop behaves as a band-pass filter whose...
Herein, uniform Co9S8 hollow boxes (Co9S8-HB) with double open ends have been fabricated by a facile technique involving solvothermal and subsequent calcination process. On the basis of time-dependent morphological evolution, generation mechanism novel Co9S8-HBs came from self-assembly process nanoparticles along their height direction. The architecture openings at both offers short ion/electron transport path, enhances diffusion ability sodium ion, as well relaxes mechanical stress upon...
In dc microgrids, line resistance on the output side of converters in parallel could lead to nonaccurate results for traditional droop control method. this letter, an active identification method based microgrid specific system structure is proposed. By injecting a pulse disturbance actively and detecting changes voltage current, between paralleled bus be obtained used compensation coefficient. Compared with other improved methods, improves current sharing accuracy restores without any...
Abstract A convenient radical cascade cyclization of aniline‐linked 1,7‐enynes with 1,3‐dicarbonyl compounds was developed to synthesize cyclopenta[ c ]quinolines in the presence AgNO 3 /K 2 S O 8 . wide range were prepared moderate excellent yields. magnified image
Abstract Carbon dioxide (CO 2 ) has been wildly employed as an environmentally benign C 1 resource for organic synthesis in the recent years. The capture of CO with primary amines easily provides corresponding carbamate salts. We described herein that salts are a useful reactant oxazolidin‐2‐ones via reaction aromatic aldehydes and terminal alkynes. A variety different functional groups were synthesized 68–91% yields only 5 mol% amount CuI catalyst. It was found synergetic effect iodide is...
Comprehensive Summary An efficient and eco‐friendly carbon nitride nanosheet (NM‐g‐C 3 N 4 )‐catalyzed decarboxylative coupling reaction of imidazo‐fused heterocycles ( i.e ., imidazo[1,2‐ a ]pyridines, benzo[ d ]imidazo[2,1‐ b ]thiazole) with ‐phenylglycines in dimethyl carbonate (DMC) has been developed. The toxic solvents, external oxidants, restricted conditions could be effectively avoided this powerful sustainable protocol. Remarkably, NM‐g‐C straightforwardly recovered by simple...
Right-half-plain (RHP) zeros can significantly deteriorate a control system's dynamic performances as it exhibits non-minimum-phase behaviors. In this paper, we investigate the occurrence mechanism of RHP in weak-grid-tied VSCs well provide guidance for minimizing their effects. A reduced-order multi-input multi-output (MIMO) transfer function VSC is firstly obtained. Then, single-input single-output (SISO) to study impact on power response further derived. The existence examined by applying...
The grid impedance ratio X/R (GIR) and the short circuit (SCR) are indexes that widely applied to stability analysis of power systems integrated with voltage source converters (VSC). Based on assumption GIR is large enough, impacts resistances neglected in most studies. In this brief, impact mechanisms analyzed by single-input single-output (SISO) transfer functions under different conditions. It found decrease has both "enhancement effect" "reduction SISO function magnitudes, while stronger...
