Recent progress in 'turbulent optimization' of toroidal configurations is described, using a method recently developed for evolving such configurations to ones having reduced turbulent transport. The method uses the G ENE gyrokinetic code to compute the radial heat flux Q gk , and the S TELLOPT optimization code with…
An ultraviolet (UV)-assisted thermal annealing (TA) method is proposed for the rapid fabrication of solution-processed zinc oxide (ZnO) thin-film transistors (TFTs). Conventional thermal treatment of zinc hydroxide solution, which was carried out at 150 °C for 60 min in air, produced ZnO materials. Electrical properti…
Although epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have been introduced for the treatment of non-small cell lung cancer (NSCLC), the emergence of secondary T790M mutation in EGFR or amplification of the Met proto-oncogene restrain the clinical success of EGFR-TKIs. Since heat shock protei…
A simple approach for preparing Fe3O4/graphene oxide (GO) nanocomposites through electrostatic self-assembly and their utilization in dye removal from aqueous media were investigated. Fe3O4 magnetic nanoparticles were synthesized by adding 1:2 ratio of Fe+2/Fe+3 to an aqueous solution, maintained in an inert atmospher…
This paper compares four different nanofabrication processes towards various two-dimensional (2D) photonic crystals (PCs) on a Y3Al5O12:Ce3+ (YAG:Ce) yellow ceramic plate phosphor (CPP) in order to enhance the luminous efficacy of YAG:Ce CPP-capped high-power white light-emitting diodes (LEDs). Compared with conventio…
We report the simple sol–gel based synthesis of size-tunable monodispersed crystalline Cu2O microspheres (CMS) and the measurement of their linear and nonlinear optical properties. Optical absorption spectra show a broad plasmonic absorption band extending from 350 to 1100 nm in general agreement with calculations bas…
The pathogenesis of protein misfolding diseases is attributed to the cytotoxicity caused by amyloidogenic prefibrillar aggregates, rather than mature fibrils. The presence of one or more amyloidogenic stretches in different proteins has been proven critical for initiating fibril formation. In the present study, we sho…
A novel family of four hybrid metal phosphonate coordination polymers is reported that are constructed from divalent metal ions (Ca, Sr, Ba, and Pb) and BPMGLY (bis-phosphonomethylglycine, a phosphonated derivative of glycine). These compounds (and their compositions) are Ca-BPMGLY (CaBPMGLY·H 2 O), Sr-BPMGLY (SrBPMGL…
Vertically aligned nanowire arrays (NWAs) of semiconductor materials, combined with the merits of the large surface-to-volume ratio and low reflectance induced by light scattering and trapping, have attracted growing interests in the fabrication of high-performance optoelectronic nano-devices due to their exceptional…
Abstract Oxygen carriers for biomass gasification are capable of absorbing oxygen from air and desorbing it in the gasifier. Based on thermodynamic equilibrium, copper, manganese, and cobalt oxides have the highest oxygen release capacities among the different oxygen carriers. These oxygen carriers were deposited on a…
Large-scale information dissemination in multicast communications has been increasingly attracting attention, be it through uptake in new services or through recent research efforts. In these, the core issues are supporting increased forwarding speed, avoiding state in the forwarding elements, and scaling in terms of…
The fluoride salt–cooled high-temperature reactor (FHR), combining high-temperature graphite-matrix coated-particle fuel (TRISO) for high-temperature gas-cooled reactors and liquid salts developed for molten salt reactors with safety systems that originate from sodium fast reactors, is a new concept reactor. The therm…
Abstract The burning of compacted modified propellant charges applied as a traveling charge in the hybrid shot scheme was studied. The block charges were manufactured by pressing fine propellant grains coated by a thin film of polyvinyl butyral. A stick from several pressed pellets was insulated over its lateral surfa…
ABSTRACT Natural rubber latex contains different allergenic proteins and peptides that restrict its application in consumer products. Small mineral particles have a comparatively high specific surface area and are therefore well suited to adsorb such biomolecules. The adsorption of such biomolecules onto different pol…
A high dye coverage on the TiO 2 surface diminishes dye-sensitized solar cell (DSSC) performances because of the significant degree of excited electron and hole recombination that results from the strong dye–dye intermolecular interactions. In this study, interplay between dye coverage and photovoltaic performances of…
INTRODUCTION: Cardiac surgery is accompanied by an increase of oxidative stress, a significantly reduced antioxidant (AOX) capacity, postoperative inflammation, all of which may promote the development of organ dysfunction and an increase in mortality. Selenium is an essential co-factor of various antioxidant enzymes.…
A novel approach, based on surface-enhanced Raman scattering (SERS) and 5,5′-dithiobis-(2-nitrobenzoic acid) (DTNB) functionalized silver nanoparticles, was developed to determine the critical micelle concentration (CMC) of cationic surfactants. A graph was generated by plotting the Raman intensity ratio between the a…
In this article, the generalized thermoelastic problem of an axially moving microbeam subjected to ramp-type heating is studied. Based on the heat conduction equation containing the thermoelastic coupling term and the classical Euler–Bernoulli thin beam theory, the thermoelastic coupling differential equation of motio…
Hollow chalcopyrite CuInSe2 nanospheres are prepared by colloidal synthesis, for the first time, and assembled inside TiO2 nanotube arrays (NTAs) as a high performance photocatalyst for hydrogen evolution. In order to improve the charge separation, we engineer the CuInSe2-based photoelectrode with a novel strategy: th…
To explore the potential of ternary blend bulk heterojunction (BHJ) solar cells as a general platform for improving the performance of organic photovoltaics, we studied a ternary BHJ system based on poly(3-hexylthiophene) (P3HT), [6,6]-phenyl C61 butyric acid methyl ester (PC 61 BM), and DTDCTB. The optimized ternary…
