This manuscript summarizes the failure mechanisms found in inorganic fullerene-type tungsten disulfide (IF-WS2) nanoparticles treated with diverse pressure loading methods. The approaches utilized to induce failure included: the use of an ultrasonic horn, the buildup of high pressures inside a shock tube which created…
Variational formulation of the problem of the analysis and synthesis of deformable structures are proposed. It allows studying nonlinear problems of structural mechanics from a single standpoint, from a consideration of the General variational principle.
Flower-like PbSe hierarchitectures constructed of dozens of microsheets were fabricated for the first time by a solvothermal route in an N,N-dimethylmethanamide and tetrahydrofuran system. X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) we…
In this work, the Fe3O4 magnetic nanoparticles (MNPs) were synthesized by a colloidal method. TEM images reveal that Fe3O4 MNPs are spherical in shape with a narrow size distribution in the range of 6–7 nm. These MNPs were used in the fabrication of two types of n-GaAs-based structures: (i) Fe3O4/n-GaAs (reference); a…
A recently developed Thouless-expansion-based diagonalization-free approach for improving the efficiency of self-consistent field (SCF) methods (Noga and Šimunek, J. Chem. Theory Comput. 2010, 6, 2706) has been adapted to the four-component relativistic scheme and implemented within the program package ReSpect. In add…
High impact toughness poly(vinyl chloride) (PVC)/(α‐methylstyrene)‐acrylonitrile‐butadiene‐styrene copolymer (70/30)/acrylic resin (ACR) blends were prepared. Incorporation of ACR did not play a negative role in thermal properties. The glass transition temperature, heat distortion temperature, and thermal stability re…
Shape-controllable synthesis of copper telluride micro/nanostructures has been successfully realized in air at room temperature by a simple galvanostatic electrodeposition route. By tuning experimental parameters such as the original Cu and Te sources, additives, deposition currents and media, copper telluride micro/n…
X-ray absorption spectroscopy (XAS) is widely used at every synchrotron to characterize the electronic structure of materials. For XAS on dilute samples, the partial fluorescence yield (PFY) from the element of interest is typically recorded as a measure of absorption. This requires an X-ray detector with sufficient s…
We propose a flexible stretchable energy harvesting device by implementing permselective pores on a poly(dimethylsiloxane) (PDMS) sheet for the direct energy conversion of pressure to electrical power. The devices consist of five layers of PDMS, giving full flexibility to the devices. From current–voltage ( I – V ) me…
Stud shear connector corrosion is an important factor for the durability degradation of steel-concrete composite structures. Stud shear connector corrosion in the natural environment is a slow process, so the shear capacity of deteriorated stud shear connector was studied by accelerate d deterioration using a galvanst…
In this paper, we have successfully synthesized and characterized poly(N-isopropylacrylamide) (PNIPAAm)-poly(ethylene glycol) diacrylate (PEGDA) microhydrogels. Various combinations of PNIPAAm-PEGDA microhydrogels were fabricated by the generation of monodisperse microdroplets whose sizes were comparable to a blood ve…
Abstract The Sonogashira–Hagihara coupling polymerization of d-hydroxyphenylglycine-based diiodo monomers 1 and 2 with p-diethynylbenzene gave novel optically active poly(phenyleneethynylene)s 3 and 4 bearing perylene moieties with number-average molecular weights (Mn's) of 4800 and 3700 in 39% and 57% yields. The CD…
In this paper, a full life cycle resource consumption model for automotive seats has been proposed based on the vehicle material-energy-pollution assessment model, and an assessment on energy consumption and abiotic depletion potential (ADP) impact is conducted to evaluate the power seat environmental performances of…
Generally, it is very difficult to control the size of large compound vesicles. Here, we introduce a novel method for the preparation of biodegradable large compound vesicles with controlled size and narrow size distribution by using aqueous nanodroplets as templates.
The photo-emission of electrons from dielectric surfaces induced by intense femtosecond laser pulses with a wavelength of 800 nm is addressed. The energy distribution of electrons emitted from SiO 2 and Al 2 O 3 samples is presented for various laser intensities. It appears that the maximum kinetic energy may reach un…
Biomass-based new materials have attracted wide attention due to their renewable characteristics. In this study, the synthesis of dimeric acid polyester polyol (DAPP) was conducted through the polymerization of dimeric acid methyl ester (DAME) and ethylene glycol (EG) using Novozym 435 as a catalyst. DAME was synthesi…
In the present work, ( Bi 1− x Fe x ) VO 4 ( x ≤ 0.40) ceramics were prepared using the solid‐state reaction method. All the ceramics could be well densified at sintering temperatures below 800°C. X ‐ray diffraction ( XRD ) results showed that monoclinic solid solution was formed within x ≤ 0.08. When x ≥ 0.10, both m…
In this paper, 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) has been used in interface modification of dye-sensitized solar cells (DSCs) with combined effects of retarding charge recombination and Förster resonant energy transfer (FRET). DCJTB interface modification significan…
The dependence of single-molecule photoluminescence intermittency (PI) or "blinking" on the local dielectric constant (ε) is examined for nile red (NR) in thin films of poly(vinylidene fluoride) (PVDF). In previous studies, variation of the local dielectric constant was accomplished by studying luminophores in chemica…
Wide-bandgap semiconductors are potential materials for photovoltaic (PV) devices in solution-based applications because of their higher stability compared with narrow-bandgap semiconductors. However, these materials are poor absorbers of photons in the solar spectrum and yield modest conversion efficiencies. Here we…
