A triple-shape memory polyurethane (TSMPU) with poly(ε-caprolactone) -diols (PCL-diols) as the soft segments and diphenyl methane diisocyanate (MDI), N,N-bis (2-hydroxyethyl) cinnamamide (BHECA) hard was synthesized via simple photo-crosslinking of cinnamon groups irradiated under λ > 280 nm ultraviolet (UV) light. Fourier transform infrared spectroscopy (FT-IR), proton nuclear magnetic resonance ((1)H-NMR) ultraviolet-visible absorption spectrum (UV-vis) confirmed chemical structure...
Colorectal cancer (CRC) is a common malignant tumor that affects people worldwide. Metagenomic analyses have shown an enrichment of Fusobacterium nucleatum (F. nucleatum) in colorectal carcinoma tissue; many studies indicated F. closely related to the carcinogenesis. In this review, we provide latest information reveal molecular mechanisms. The known virulence factors promote adhesion intestinal epithelial cells via FadA and Fap2. Besides, Fap2 also binds immune causing immunosuppression....
The multicomposite styrene-based shape memory polymer can be selectively actuated by applying selective stimuli due to the heating properties of Fe<sub>3</sub>O<sub>4</sub>(30 kHz alternating magnetic field) and CNT (13.56 MHz radiofrequency nanofillers. Therefore, possesses a well-controlled multiple temporary recovery capability.
A multi-stimuli sensitive shape memory poly(vinyl alcohol)-graft-polyurethane was synthesized. Fourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H-NMR) confirmed the chemical structure of material. The material exhibits good water-induced behavior a thermally induced dual effect. Further study indicated that triple behavior. Differential scanning calorimetry (DSC) dynamic mechanical analysis (DMA) demonstrated polymer possesses wide transition...
In this work, a novel type of shape memory polymer nanocomposite was fabricated using chemically cross-linked poly(ε-caprolactone) with allyl alcohol as the matrix and Fe3O4 nanoparticles decorated conductive multiwalled carbon nanotubes (Fe3O4@M) magnetism electricity responsive source. The exhibited excellent performance multistage stimulus recovery from temporary to permanent shape, triggered by an alternating magnetic field, electric field hot water, respectively. Uniquely, also...
Calorific value is an essential fuel parameter during the process of energy utilization. Forty-four coal samples with different calorific values were quantitatively analyzed by laser-induced breakdown spectroscopy (LIBS) in this paper. The influences spectral preprocessing methods such as smoothing, standard normal variate transformation (SNV), multiplicative scatter correction (MSC), mean centering (MC), and derivation convolution (Savitzky–Golay) on quantitative model have been compared....
Shape memory polymers (SMPs) are expected to play more and important roles in space-deployable structures, smart actuators, other high-tech areas. Nevertheless, because of the difficulties fabrication programmability temporary shape recovery, SMPs have not yet been widely applied real fields. It is ideal incorporate different independent functional building blocks into a material. Herein, we designed simple method four blocks: neat epoxy-based (neat SMEP) resin, an SMEP composited with Fe3O4...
The mechanical properties of steel with different aging degree microstructure was estimated by combining LIBS and chemometrics (CCA SVR).
The Hot Universe Baryon Surveyor (HUBS) mission is proposed to study "missing" baryons in the universe. Unlike dark matter, baryonic matter made of elements periodic table, and can be directly observed through electromagnetic signals that it produces. Stars contain only a tiny fraction known present Additional are found diffuse (gaseous) form, or between galaxies, but significant has not yet been seen. latter (missing baryons) thought hiding low-density warm-hot ionized medium (WHIM), based...
Living cells can alter their shapes and functions in response to physical cues at the cell–substrate interface, consequently temporal variations of substrate surface are thought be very important governing cell behaviors. In this study, a thermally-activated shape memory function was employed tune dynamic change topography features on polymer nanocomposite substrate. The is composed chemically cross-linked poly(ε-caprolactone) with allyl alcohol Fe3O4 nanoparticles. regular arrays...
The real-time quantitative analysis of the calorific value pulverized coal particle flow is important for efficient and clean combustion coal.
Shape memory polymers (SMPs) are the simplest and most attractive alternatives for soft substrates of typical bilayer wrinkle systems because shape fixity recovery capabilities. Herein, we have successfully programmed large compressive strains in chemical cross-linking polystyrene (PS) microparticles via nanoimprint lithography, which acted as substrate a system using gold nanoparticle (Au NP) film top layer. When triggered by two different stimuli (direct heating toluene vapors), thin Au NP...
This work aims to explore and design a family of multistable metastructures, which are actuated by rotational motion. The bi-stability criteria for single pre-shaped beam unit studied firstly using an analytical model finite element method.
