Drinkwater, J. M., Tsao, R., Liu, R. and Wolyn, D. J. 2014. Genetic variation and heritability of rutin and glutathione concentrations in asparagus spears. Can. J. Plant Sci. 94: 1355–1362. Asparagus (Asparagus officinalis L.) spears contain numerous phytochemicals, including rutin (a flavonoid) and glutathione (a bio…
We describe a series of experiments designed to investigate the conformational transition that highly-branched polymers with ligands undergo when interacting with bacteria, a process that may provide a new sensing mechanism for bacterial detection. Fluorescent highly-branched poly(N-isopropyl acrylamide)s (HB-PNIPAM)…
ABSTRACT Thiophenol and p‐nitrothiophenol were evaluated as promoters for the ring opening polymerization of benzoxazine. The ring‐opening polymerization of p‐cresol type monofunctional N‐phenyl benzoxazine 1a with 10 mol % of thiophenols proceeded at 150 °C, leading to the high conversion of 1a more than 95% within 5…
Abstract The transformation of potassium catalyst during coal pyrolysis and steam gasification has been studied in a fixed‐bed reactor. The gasification residues were obtained by leaching in the water and drying in an oven. The crystallite constituents and ash constituent of the gasification residue were identified by…
The effects of the deposition temperature on the microstructure, crystallographic orientation, and electrical properties of a 10-μm thick evaporated Si thin-film deposited on glass and crystallized using a diode laser, are investigated. The crystallization of the Si thin-film is initiated at a deposition temperature b…
Strontium titanate (STO) thin films 90 nm in thickness were grown on a Pt substrate through atomic layer deposition (ALD). The as-deposited ALD STO grown with an ALD cycle ratio of 1:1 (Sr:Ti) was in an amorphous phase, and annealing at 800 °C in air crystallized the films into the perovskite phase. This phase change…
A self‐assembling molecule, n‐octadecane phosphate, is successfully synthesized and used to modify the surface property of carbon nanofibers (CNFs). Both untreated CNFs (CNFs(u)) and treated CNFs (CNFs(t)) are incorporated in polyimide (PI) as filler to study the interfacialproperty‐determined thermal, mechanical, an…
Tribological behaviors of carbon fiber reinforced polyetheretherketone (CFR PEEK) sliding against silicon carbide ceramic under seawater lubrication were investigated. The effects of sliding velocity (from 0.5 to 1.5 m/s) and contact pressure (between 0.66 and 2.64 MPa) on friction coefficient and wear rate have been…
A Si–SiO2–MgO device showing nonvolatile resistive switching effect is fabricated. It is observed the resistance of the device changed from high value to low value at a certain transition voltage after being stimulated by a large current. In addition, the transition voltage shifts reproducibly under a reversed large c…
The face-shear vibration modes of [011] poled Zt ± 45° cut relaxor-PT crystals and their applications for linear piezoelectric motors were investigated. Unlike piezoelectric ceramics, the rotated crystal was found to exhibit asymmetric face-shear deformations, and its two high-order face-shear modes degraded into two…
We report GaN thin film transistors (TFT) with a thermal budget below 250 °C. GaN thin films are grown at 200 °C by hollow cathode plasma-assisted atomic layer deposition (HCPA-ALD). HCPA-ALD-based GaN thin films are found to have a polycrystalline wurtzite structure with an average crystallite size of 9.3 nm. TFTs wi…
The transformation from a disordered into an ordered version of the zeolite natrolite occurs on prolonged heating of this material in the crystallizing medium, but not if the mother liquor is replaced by water or an alkaline solution. This process occurs for both aluminosilicate and gallosilicate analogues of natrolit…
In this paper, the heterofullerenes made of the smallest fullerene, C20 were investigated by quantum chemistry calculations based on density functional theory. The geometrical structures, energies, electronic properties, and the aromaticities of the C19X (X = B, N, O, Al, Si, P, S, Ga, Ge, As, and Se) cages were studi…
The addition of spacing layers in organic photovoltaic cells (OPVs) can enhance light absorption by optimizing the spatial distribution of the incident optical field in the multilayer structure. We explore the optical spacing effect in OPVs achieved using a diluted electron acceptor layer of C60. While optical spacing…
We have investigated structural and magnetic properties at low temperature phases in spinel oxides Fe1+xV2−xO4 (0 ≤ x ≤ 0.4) using synchrotron powder diffraction, magnetization, and specific heat experiments. The only lattice distortion from a cubic to a tetragonal phase (c > a) occurs at ferrimagnetic order temperatu…
This paper presents simulation results of air-blown coal gasification-based combined cycles when using low-rank coals, by means of a previously realized thermodynamic model. In detail, besides considering a sub-bituminous coal, attention is also paid to a brown coal, pre-dried to reduce its high moisture content. When…
The Combustive Sound Source (CSS) is being developed as an environmentally friendly source to be used in ocean acoustics research and surveys. It has the ability to maintain the same wide bandwidth signal over a 20 dB drop in source level. The CSS consists of a submersible combustion chamber filled with a fuel/oxidize…
We have systematically explored the time-dependent plasticity of (0 0 0 1)-oriented ZnO single crystal through spherical indentation tests. Constant load indentation creep tests were performed in elastic strain and elastic–plastic strain regimes. In both regimes, creep indeed occurred at ambient temperature. With the…
Abstract TiO2‐based dye‐sensitized solar cells (DSSCs) sensitized with the Ru‐dyes N719 and Z907, are subjected to prolonged reverse bias (RB) by imposing a constant current density of 25 mA cm−2 for up to 1000 h. The temporal changes of the DSSCs during the aging process are followed by the periodical recording of cu…
Indium-tin-oxide (ITO) free inverted organic solar cells (IOSCs) based on aluminum-doped zinc oxide (AZO) cathode, low-temperature aqueous solution processed zinc oxide (ZnO) electron extraction layer, and poly(3-hexylthiophene-2, 5-diyl):[6, 6]-phenyl C61 butyric acid methyl ester blend were realized in this work. Th…
