The present paper introduces an intelligent anticorrosion coating, based on the mechanized hollow mesoporous silica nanoparticles (HMSs) as smart nanocontainers implanted into self-assembled nanophase particles (SNAP) coating. As key component, assembled by installing supramolecular nanovalves in form of bistable pseudorotaxanes external surface HMSs realize pH-responsive controlled release for corrosion inhibitor, caffeine molecules. encapsulate molecules at neutral pH, and either under...
The pH-responsive smart nanocontainers based on hollow mesoporous zirconia nanospheres are used to construct intelligent anticorrosion coatings.
Luminescent graphene quantum dots (GQDs) have been capped onto the nanopores of mesoporous silica nanoparticles (MSNs) through an acid-cleavable acetal bond. Herein, GQDs behave as dual-purpose entities that act capping agents and also exhibit excellent photoluminescence property.
The self-complexation of mono-benzimidazole functionalized β-cyclodextrins was investigated. unique molecular structure employed as supramolecular nanovalves were installed on the external surface mesoporous silica to assemble mechanized nanoparticles, which showed pH-triggered release property.
SiO2-imidazoline nanocomposites (SiO2-IMI) owning high loading capacity of corrosion inhibitor, 1-hexadecyl-3-methylimidazolium bromide (HMID), and a special acid/alkali dual-stimuli-accelerated release property have been synthesized via one-step modified Stöber method. SiO2-IMI were uniformly distributed into the hydrophobic SiO2 sol to construct "host"-"guest" feedback active coating with superhydrophobic surface (SiO2-IMI@SHSC) on aluminium alloy, AA2024, by dip-coating technique. as...
We report on thermally evaporated chromium oxide (CrOx) as cathode interfacial layer to improve the efficiency and stability in air for bulk heterojunction solar cells of poly(3-hexylthiophene) (P3HT) [6,6]-phenyl C61 butyric acid methyl ester (PCBM). Devices with CrOx layers show higher power conversion (PCE) than those without layer. improved more 100 times that devices or LiF tentatively attributed an electronic tunneling electron collection a protective Al assumably by minimizing...
Mechanized silica nanoparticles installed with the reversible bistable [2]pseudorotaxanes achieve multistage pH-controlled release of cargoes.
Organic solar cells are commonly susceptible to degradation in air. We present that insertion of a thin layer thermally evaporated copper oxide (CuOx) between the organic active and Al cathode can greatly extend lifetime P3HT:PCBM based bulk heterojunction cells. The performance be further improved by applying an interfacial bilayer CuOx/LiF. Our results suggest CuOx functions not only as charge transport but also protection layer, which prevents formation thick organic-Al interdiffusion...
ZnO thin films are prepared on glass substrates by filtered cathode vacuum arc (FCVA) deposition technique. A new method is demonstrated to extract the refractive index, thickness and optical band gap of from transmission spectrum alone. The index calculated extremes interference fingers. divided into two terms, non-interference term effect term. simulating term, used calculate with gained thickness. results compared measurements using an ellipsometry a scanning electron microscope.
The isolated input-parallel-output-series (IPOS) partial power converter (PPC), which is composed of a dc transformer (DCX) cell and voltage regulation (VR) cell, regarded as promising solution for distribution systems only delivered by the VR under different conditions.

Land-use scene classification (LUSC) is a key technique in the field of remote sensing imagery (RSI) interpretation. A convolutional neural network (CNN) widely used for its ability to autonomously and efficiently extract deep semantic feature maps (DSFMs) from large-scale RSI data. However, CNNs cannot accurately rich spatial structure information RSI, easily lost due many pooling layers, so it difficult ensure integrity (SSFMs) DSFMs with only LUSC, which can affect performance. To fully...
Hyperspectral image (HSI) shows great potential for application in remote sensing due to its rich spectral information and fine spatial resolution. However, the high dimensionality, nonlinearity, complex relationship between features of HSI pose challenges accurate classification. Traditional convolutional neural network (CNN)-based methods suffer from detail loss feature extraction; Transformer-based rely too much on quantity quality HSI; graph (GNN)-based provide a new impetus...
With the development of high-performance and high-quality permanent magnet materials high-power converter technology, direct-drive synchronous wind turbines (D-PMSG) have been increasingly used. The time-varying non-linear characteristics power systems make it difficult for traditional control methods to achieve satisfactory results. Therefore, application advanced in has important theoretical practical value. D-PMSG is taken as research object a method that combines grey prediction with PI...
