We report the structural and electrical properties of a Sc 3+ -doped TiO 2 (Ti 0.99 Sc 0.01 O 2−δ ) thin film prepared by RF magnetron sputtering. The thin film prepared at 100 °C exhibits the anatase (112) peak, although the thin films prepared at temperature above 200 °C show the rutile (200) peak. The lattice const…
In this paper, the synthesis, SERS performance and application in glucose sensing of hierarchical 3D Ag nanostructures (NSs) are reported. Large-scale Ag jujube-like architectures were produced via the galvanic reaction process in a mixed solution of trisodium citrate (TSC) and AgNO3 on Cu nanoparticles disproportione…
We investigate the effects of humidity on the vibrations of carbon nanotubes (CNTs) using two types of CNT cantilevers: open-ended and close-ended CNT cantilevers. As the humidity increases, the resonant frequency of the open-ended CNT cantilever decreases due to the adsorption of water molecules onto the CNT tip, whe…
With the expanding applications of carbon nanotubes (CNT) in biomedicine and agriculture, questions about the toxicity and biocompatibility of CNT in humans and domestic animals are becoming matters of serious concern. This study used proteomic methods to profile gene expression in chicken macrophages and heterophils…
Here we demonstrate on the ultra-fast synthesis route for the preparation of highly ordered FDU-12 with a 3D mesoporous structure and large and tuneable pore diameters ranging from 9.31 to 19.14 nm using microwave irradiation technique at various reaction temperatures ranging from 100 to 250 °C. High-end techniques su…
Nanostructured LaNiO3−x (x> 0) was prepared at low temperature between 500–800 C by the sol–gel method. Their potentials as a thermoelectric material were investigated. The minimum temperature to form the LaNiO3−x phase in air was 600 C. The samples sintered between 600 and 800 C had a grain size of 18–31 nm and showe…
The hydroxyl derivative of soybean oil (SDEG) was obtained as a result of the epoxidation of soybean oil followed by the opening of oxirane rings in the reaction with diethylene glycol (Scheme A). This derivative was used in the process of fusion with bisphenol A-based low-molecular-weight epoxy resin EPR 162 (Scheme…
Self-organized criticality describes the emergence of complexity in dynamical nonequilibrium systems. In this paper we introduce a unique approach whereby a driven energy conversion is utilized as a sampling bias for ordered arrangements in molecular dynamics simulations of atomic and molecular fluids. This approach g…
Electron and energy transfer processes from higher excited states are attractive for efficient photoenergy utilization because energy dissipating internal conversion processes can be avoided. In the present study, charge separation processes in meso-substituted Sb- and Ge tetraphenylporphyrins (TPPs) were investigated…
Searching for new ways to utilize rubber and polymer waste has been the focus of many studies conducted by research centers and companies worldwide. In this study, the influence of extrusion conditions on the properties of thermoplastic compositions containing post-production recycled high density polyethylene (PE-HD)…
A new method for fast solvent removal in gel spinning was investigated. Instead of solvent evaporation or coagulation as conventionally used, the new method involves mechanically twisting the gel‐fiber along the fiber axis. By removing the majority of solvent in the gel‐fiber by mechanical twisting not only the emissi…
We investigate the domain wall speed of a ferroelectric PbZr0.48Ti0.52O3 (PZT) thin film using an atomic force microscope incorporated with a mercury-probe system to control the degree of electrical fatigue. The depolarization field in the PZT thin film decreases with increasing the degree of electrical fatigue. We fi…
Abstract In order to better use the hemp shiv in manufacturing particleboard panels, tests for determining the mechanical and physical properties of this particleboard were performed according to the Chinese standard for wood-based paneling. The results showed the following. (1) The properties of the particleboard are…
The study of overdoped FeTe 1−x Se x (0.5 < x < 1) polycrystalline superconductor samples is reported. The samples were prepared using a melting technique previously developed by our group. Increasing the Se content a phase separation related to the formation of FeSe inside the Fe(Se,Te) phase happens, as demonstrated…
The elastic moduli of ${\mathrm{Fe}}_{1\ensuremath{-}c}{\mathrm{Co}}_{c}$ ($c\ensuremath{\le}0.2$) alloys are found to decrease strongly with increasing temperature, but show very weak alloying effects for both low-temperature ferromagnetic and high-temperature paramagnetic states. For temperatures slightly below and…
We report a strategy to remove the reflections resulted from the finite embedded transformation-optical design by proposing a theory of impedance-tunable transformation optics, on which the functions of impedance coefficients can be derived in the original space without changing the refractive index. Based on the appr…
Step-by-step polymer film buildup processes lead to polymer coatings, e.g., polyelectrolyte multilayers, of various structures ranging from continuous smooth films to droplet like discontinuous coatings. Yet, the origin of these different behaviors depending upon the system is not yet known. This study is a first atte…
Homogeneous esterification of cellulose with octanoyl chloride (a long-chain fatty acid) was investigated in lithium chloride/N,N-dimethyl acetamide (LiCl/DMAc) medium. Cellulose was readily esterified by the octanoyl chloride, as shown by 1H NMR analysis. The effects of the ratio of octanoyl chloride to cellulose hyd…
Among the families of iron-based superconductors, we investigate flux pinning mechanisms in the Fe(Se 1− x Te x ) compound. We perform magneto-resistance and current-voltage measurements on single-crystals, as well as on several epitaxial thin films grown on different substrates (CaF 2 , LaAlO 3 ). The activation ener…
Nanoscrolls (papyrus-like nanostructures) are very attractive structures for a variety of applications, owing to their tunable diameter and large accessible surface area. They have been successfully synthesized from different materials. In this work, we investigate, through fully atomistic molecular dynamics simulatio…
