Molecular dynamic simulation of a faceted ice-Ih crystal with the largest dimension of 0.06 µm in a vacuum is performed by employing the TIP4P intermolecular potential at temperatures Tm − 23, Tm − 13, and Tm − 1 K, where Tm is the melting point of the TIP4P bulk ice. We thereby observe at all the temperatures that th…
This work reports on the long-range order of single as-implanted and annealed ZnO:Co nanowires studied using a hard X-ray nanoprobe. For all nanowires, nano-X-ray fluorescence maps reveal a homogeneous distribution of Co ions implanted along the nanowires. For the as-implanted nanowires, however, nano-X-ray diffractio…
Abstract Driven by the association of chemical weak forces and solvent effects, zero‐ to two‐dimensional nanostructures of thiophene‐substituted perylene bisimide such as spheres and blocky structures were obtained. Light‐controlled intramolecular charge transfer from the trithiophene unit to the perylene bisimide in…
The process of thermoforming a carbon fiber reinforced thermoplastic (CFRTP) has increased its presence in the automotive industry for its wide applicability to the mass production car. A non-isothermal forming for CFRTP can shorten its cycle time to less than 1 minute. In this paper, the textile reinforcement FE mode…
In recent explosion accidents on onshore petrochemical facilities, it has been concluded that a deflagration‐to‐detonation‐transition (DDT) took place, both with Liquefied Petroleum Gas (LPG) and gasoline vapor. DDT has also been observed in a number of large‐scale experiments. DDT leads to very high pressures (16–20…
A new printed log-periodic microstrip antenna (LPMA) with extended bandwidth based on a composite right/left-handed transmission line (CRLH-TL) is proposed. The microstrip patches composed of mushroom structures are placed in a log-periodic way, so that the characteristic of bandwidth enhancement can be achieved. The…
In this paper, a low-cost and high-efficiency microprocessing modification technology for the surface of bisphenol A polycarbonate (BAPC) material was achieved (in particular, from hydrophilicity to hydrophobicity) at high laser scanning speeds (600–1000 mm s − 1) and using an all-solid state, Q-switched, high-average…
Positively charged gold nanoparticles can be produced in the aerosol state by ultraviolet irradiation of aerosols at wavelengths above the gold ionization energy. Spark-discharge-generated aerosol gold nanoparticles were mobility-classified, neutralized, and then exposed to ultraviolet irradiation at 185 nm. The charg…
We theoretically investigate the light-reflection properties of silicon nanorod (SiNR) arrays with square and hexagonal alignments. The reflectivity of photon flux (RPF) is introduced to evaluate the light-reflection capability of SiNR arrays. The quantum efficiency (QE) varies on changing the geometric parameters of…
The reaction of propargyl alcohol with hydroxyl radical has been studied extensively at CCSD(T)/aug-cc-pVTZ//MP2/cc-pVTZ level. This is the first time to gain a conclusive insight into the reaction mechanism and kinetics for this important reaction in detail. Two reaction mechanisms were revealed, namely addition/elim…
The method of the efficient analysis of di(2‐diethylhexyl) phthalate, tri(2‐ethylhexyl) trimellitate, di(2‐ethylhexyl) terephthalate, and other phthalate plasticizers concentrations in plasticized poly(vinyl chloride) (PVC) was developed. The method is based on quantitative dissolution of the PVC sample in methyl ethy…
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…
