Studies that deal with small and intermediate break loss of coolant accident (LOCA) conditions, for which steam pressure remains relatively high in the reactor primary system, are scarce, even though it has been sometimes observed that steam pressure could have a significant effect on the high temperature (HT) oxidati…
Recent experiments suggest that benzotriazinyl-derived radicals are promising building blocks for the design of new functional materials. Herein, a detailed computational study of the main structural and magnetic features of two prototypes of this family of radicals is presented. By means of several computational tech…
The ability of a zirconium alloy to resist corrosion relies on a compromise between two opposing strategies. Minimizing the hydrogen pickup fraction (HPUF) by invoking metallic electron conduction in the barrier oxide results in rapid parabolic oxide growth. On the other hand, slow sub-parabolic barrier oxide growth,…
The wild plant known as Calotropis procera is important in medicine, industry and ornamental fields. Due to spread in areas that suffer from environmental stress, it has a large number of tolerance genes to environmental stress such as drought and salinity. Proline is one of the most compatible solutes that accumulate…
The phonon dispersions and scattering rates of the thermoelectric material ${\mathrm{Ag}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{1+x}{\mathrm{Te}}_{2+x}\phantom{\rule{0.28em}{0ex}}(x=0,0.1,0.2)$ were measured with inelastic neutron scattering, as function of both temperature $T$ and off stoichiometry $x$. In addition, detai…
During a loss-of-coolant accident (LOCA), the oxide layer grown during normal operations is expected to have a protective effect against high-temperature steam oxidation. However, with respect to post-quench ductility, such a barrier effect may be counterbalanced by a partial dissolution of the pre-oxide layer and ass…
Micrometer-sized single-crystalline In₂Se₃ nanosheets are synthesized by epitaxial growth from In₂Se₃nanowires. The In₂Se₃ nanosheets possess anisotropic structural configuration with intralayer covalent bonding and interlayer van der Waals bonding. Phototransistors based on the In₂Se₃ nanosheets are realized, and the…
4H-Pyranylidene-containing push-pull chromophores built around a bithiophene (BT) π relay or a rigidified thiophene-based unit, namely cyclopenta[1,2-b:3,4-b']dithiophene (CPDT) or dithieno[3,2-b:2',3'-d]pyrrole (DTP), have been synthesized and characterized. The effect of these different relays on the polarization an…
Abstract In this work, we develop a new simple synthesis method of hollow polycrystalline monophase vaterite particles without impurities such as calcite and toxic buffer (tris(hydroxylmethyl)aminomethane: Tris). Starting materials consist of CaCl2, NaHCO3, NaCl, and a flavin mononucleotide, a vitamin B2 derivative. T…
In this paper, we have demonstrated an effective method for fabricating disordered subwavelength structures (d-SWSs) on fused silica using thermal dewetted Ag nanoparticles at lower temperatures (<300°C) with a vacuum. Theoretically and experimentally, we investigate the effects of the film thickness, annealing temper…
Thermoresponsive poly(N-isopropylacrylamide) (PIPAAm)-immobilized surfaces for controlling cell adhesion and detachment were fabricated by the Langmuir-Schaefer method. Block copolymers composed of polystyrene and PIPAAm (St-IPAAms) having various chain lengths and compositions were synthesized by reversible addition-…
We obtained the contact pair copper–aluminum copper coating by using a magneto plasma accelerator. The process is realized during supersonic copper plasma jet flowing into the chamber filled with the air atmosphere. Copper jet is carried out of the accelerating channel towards the aluminum target. Plasma jet is genera…
This paper presents a novel and unique feature of metallacarboranes, consisting of the linkage of this redox electro-active site to a stretchable polymer. This is based on polyTHF, a known and applied material. This hybrid material has the two ends functionalized: one with the aforementioned redox molecule and the oth…
In this study, corrosion behaviour of magnesium AZ31 alloy sheets produced by different casting methods was investigated. Magnesium AZ31 sheets of 2 mm in thickness produced by conventional direct chill casting+rolling and AZ31 sheets of 2 mm in thickness and 1500 mm in width produced by twin roll strip casting+rollin…
The optical properties of porous silicon structures coated with nanodiamond films have been investigated for use as antireflective and protective coatings of silicon solar cells.
Immobilization of lanthanide organic complexes in meso-organized hybrid materials for luminescence applications have attracted immense interest due to the possibility of controlled segregation at the nanoscopic level for novel optical properties. Aimed at enhancing the luminescence intensity and stability of the hybri…
One of the most effective ways of synthesizing carbon nanotubes is the arc discharge method. This paper describes a system supported by a magnetic field which can be generated by an external coil. An electric arc between two electrodes is stabilized by the magnetic field following mass flux stabilization from the anod…
The thermal properties of amorphous and crystalline phases in chalcogenide phase change materials (PCM) play a key role in device performance for non-volatile random-access memory. Here, we report the nanothermal morphology of amorphous and crystalline phases in laser pulsed GeTe and Ge2Sb2Te5 thin films by scanning t…
We have prepared a series of water-soluble, pyridine-containing poly(aryleneethynylene)s (PAEs), consisting of alternating units of substituted ethynylpyridines and ethynylbenzenes. Water solubility is achieved by branched oligoethylene glycol (swallowtail) side chains. The fluorescence quantum yield (ϕ) of these PAEs…
Optical remote sensing of the earth from air and space typically utilizes several channels from visible (VIS), near infrared (NIR) up to the short wave infrared (SWIR) spectral region. Thin-film optical filters are applied to select these channels. Filter wheels and arrays of discrete stripe filters are standard confi…
