Mass loading, 20 elemental concentrations, and time series of aerosol particles were investigated over the China Dust Storm Research (ChinaDSR) observational network stations from March to May 2001 during intensive field campaign period ACE‐Asia. Four extensive several minor dust storm (DS) events observed. balance calculations showed that 45–82% observed mass was attributable Asian soil among sites, in which Ca Fe contents are enriched 12% 6%, respectively, Western High‐Dust source regions...
Surface spinodal demixing of DIO:ITIC leads to poor electron mobility, while the CN:Y6 blend undergoes a binodal process which is similar that occurs in bulk liquid layer, contributing uniform vertical crystallinity distribution.
An active integrated broadband photonics multi-beamformer using optical true-time delay induced Blass matrix is designed and demonstrated. The constructed on a standard silicon-on-insulator platform, incorporating on-chip modulator array photodetector alongside multi-beamforming network. network utilizes architecture based to precisely control the power of input microwave signals. Furthermore, wavelength division multiplexing technology achieved by multi- lasers used decouple signals from...
Molecule engineering has been demonstrated as a valid strategy to adjust the active layer morphology in all-small-molecule organic solar cells (ASM-OSCs). In this work, two non-fullerene acceptors (NFAs), FO-2Cl and FO-EH-2Cl, with different alkyl side chains are reported applied ASC-OSCs. Compared FO-2Cl, FO-EH-2Cl is designed by replacing octyl branched iso-octyl chains, leading an enhanced molecular packing, crystallinity, redshifted absorption. With small molecule BSFTR donor, device of...
Abstract The power conversion efficiencies (PCEs) of organic photovoltaic cells employing donor (polymer):acceptor (small molecule) bulk heterojunction (BHJ) are being rapidly improved. phase segregation along vertical (film‐depth) direction the active layer, referring to immiscibility between and acceptor, leads vertically varied nonlinearly distributed composition, optical electronic properties. However, correlation miscibility performance is still confusing. Here, it semi‐empirically...
Tuning the phase separation within active layer morphology is of great importance for enhancing device performance organic solar cells (OSCs), especially all-small-molecule OSCs (ASM-OSCs). Herein, we demonstrate that an optimal could be achieved through thermal annealing (TA) two small-molecule acceptors, F-2Cl- and FO-2Cl-based ASM-OSCs. The acceptor FO-2Cl, by introducing oxygen atoms into backbone F-2Cl, exhibits red-shifted absorption, enhanced crystallinity, improved electron mobility...
The poor chemical miscibility between metal and organic materials usually leads to both structural energetic mismatches at gold/organic interfaces, thereby, high contact resistance of electronic devices. This study shows that the field-effect transistors is significantly reduced by one order magnitude, reforming interface gold electrodes conjugated polymers upon a polymer insulator-assisted thermal annealing. Upon an optimized solution process, homogenously distributed within amorphous...

During solvent evaporation, the phase evolution dynamics different components at locations are not synchronic within incrementally concentrated liquid films, determining final anisotropic morphology performance.

Although metal or oxide conductive films are widely used as electrodes of electronic devices, organic would be more favorable for next-generation electronics. Here, using some model conjugated polymers examples, we report a class highly and optically transparent polymer ultrathin layers. Vertical phase separation semiconductor/insulator blends leads to ordered two-dimensional (2D) layer conjugated-polymer chains on the insulator. Afterwards, thermally evaporated dopants lead conductivity up...
