The synthesis of lotus-root-like NiO nanosheets and flower-like microspheres was realized through a simple hydrothermal method subsequent calcination. diameter the is about 400 nm pore size 5∼20 nm. 2.5 μm, are composed staggered nanosheets. During synthetic procedure, aqueous ammonia used as an alkaline complexing reagent, PVP template. Interestingly, when pH value precursor solution increased from 8.30 to 10.80, gradually assembled into microspheres, indicating that plays key role in...
Alismatis Rhizoma (AMR) is a well-known natural medicine with long history in Chinese and has been commonly used for treating wide range of ailments related to dysuria, edema, nephropathy, hyperlipidaemia, diabetes, inflammation as well tumors clinical applications. Most beneficial effects AMR are attributed the presence protostane terpenoids, major active ingredients (AMR). In this study, systematic high performance liquid chromatography/diode-array detector/quadrupole-time-of-flight mass...
A hybrid cured resin with excellent dielectric and thermal properties was prepared bismaleimide–triazine (BT) modified 2,2′-diallylbisphenol (DBA). The of the were investigated, effect DBA concentration on curing reaction determined. Results indicated that significantly influenced product. BT resins exhibited outstanding stability (initial decomposition temperature over 400°C), although slightly lower than pure resins. constant loss decreased when introduced into Moreover, fabricated showed...
Abstract The shape memory polymers (SMPs) and alloys (SMAs), as typical smart materials, have got enormous attention in the fields of aerospace, microsystems, biomedicine due to their superior properties. Combining high strength SMAs large deformation SMPs, polymer composites with fibers (SMPC‐SMAs) formed by SMP matrix SMA dual advantages SMPs. For different loading conditions, mechanical behaviors SMPC‐SMAs are investigated this work, combining mechanics composite materials constitutive...
Introduction Several teaching methods have been used in clinical nursing to increase quality and efficiency, but disagreements over their effects persist. This study will evaluate the of five on students’ knowledge, skill scores, learning satisfaction, patients’ satisfaction. Methods We conduct searches PubMed, Embase, Web Science, The Cochrane Library, China National Knowledge Infrastructure Database (CNKI), Biological literature database (CBM), Wanfang Database, Science Technology Journal...
By a sol–gel processing, the nano‐TiO 2 / silk fibroin (SF) composite films were prepared. One‐dimensional (1D) Raman, two‐dimensional (2D) correlation Raman spectroscopy, and 13 C cross‐polarization magic‐angle‐spinning nuclear magnetic resonance ( CP‐MAS NMR) used to characterize structural evolution of SF as content increased from 0 0.4 wt%. The experimental data demonstrated that secondary structures in pure film random coil, α‐helix β‐sheet structures. particles formed might induce...

Mechanical metamaterials can achieve fantastic properties fabricated using artificial structural design. In this study, shape memory polymers (SMP) were combined to design variable gradient zero Poisson ratio mechanical and 3D printing was used fabricate complex structures. The performance of these structures investigated by conducting simulation calculations analyze the variations Poisson’s with different wall thicknesses, cell internal angles, inclined length gradients. Through analysis...

Then, joint simulation inversion built in ISIGHT-MATLAB-ABAQUS integrated environment optimize time domain Prony series using downhill simplex algorithm. The results show that average...
Abstract Shape memory polymer composites (SMPC), which are a type of stimuli-responsive material, show better mechanical properties than pure shape polymers. However, different engineering applications have requirements for the fiber content SMPC. For example, some parts structure require more fibers to enhance strength, while other fewer maintain deformability. In order solve this problem, functionally graded composite (FG-SMPC) is proposed in work. The contents FG-SMPC can be changed along...
Shape memory polymer (SMP) has drawn much attention in the fields of aerospace, microsystems and biomedicine as a typical smart material with unique shape properties.
