We investigate the physical properties of the Ba(1-x)K(x)BiO(3) compounds with a focus on the optical properties. Results from the simple Holstein model, describing a single band coupled to an oxygen breathing mode with parameters derived from first principles calculations, are in excellent agreement with a broad rang…
We the Editor and Publisher of Journal of Experimental Nanoscience retract the following three articles:1. Nazari, Ali, and Shadi Riahi. “The effects of ZnO2 nanoparticles on split tensile strength of self-compacting concrete.” Journal of Experimental Nanoscience 7.5 (2012): 491-512, https://www.tandfonline.com/doi/fu…
We use a simulation code, based on Molecular Dynamics and Monte Carlo, to investigate the depth-dose profile and lateral radial spreading of swift proton beams in liquid water. The stochastic nature of the projectile-target interaction is accounted for in a detailed manner by including in a consistent way fluctuations…
Solute atom nanoscale precipitates are responsible for the favourable mechanical properties of heat treatable aluminium alloys such as Al-Mg-Si (6xxx). The shape, structure and strengthening properties of age-hardening precipitates depend on alloy composition and thermo-mechanical history. We seek an improved understa…
Die Bewegung von Reaktanten bei der Methanol-zu-Olefin-Reaktion in einem großen Reaktorbett wurde mit Synchrotron-Röntgenbeugung visualisiert (siehe Bild). Strukturänderungen des Katalysators dienen als Indikator für die Bildung von reaktiven Zwischenstufen und Koks, die entlang dem Reaktorbett verfolgt werden können.…
Pyridine performs: 3,8,13-Tripyridyltruxenes are thermally stable cathode buffer materials in organic thin-film solar cells. This class of truxene derivatives provides a high power-conversion efficiency of up to 4.41 %. In contrast, the use of the analogous 3,8,13-triphenyltruxene resulted in poor performance of the s…
Municipal solid waste incineration (MSWI) bottom ash could be solidified with fly ash addition at 100 °C, and the flexural strength of solidified specimens reached almost 20 MPa. The strength development was found to be due mainly to C–S–H gel formation. Leaching tests were conducted to determine the amount of heavy m…
This short review describes how the basic reactions of photosynthesis can be broken down into four distinct steps. The current understanding of the molecular mechanisms of these steps, within light-harvesting complexes and reaction centres, in this process is discussed as a framework for the construction of artificial…
Nanoantennas coupled to nanobolometers have been used as detectors of optical radiation. They are typically manufactured using two different materials: one for the nanoantenna and another for the nanobolometer. However, those metals used to fabricate nanoantennas also present a bolometric response. Therefore, antenna-…
A novel electron-accepting unit cyclopenta[2,1-b:3,4-c']dithiophene-4-one (CPDTO-c'), which is an isomer of CPDTO-b' was developed. CPDTO-c' can be incorporated into the D-A backbone through 5, 7 positions. The 2 position of CPDTO-c' can be easily functionalized with an electron-withdrawing chain. By copolymerizing CP…
The effect of hydrogen bonding (H-bonding) on vesicle structure and its formation of the mixture of AB/BC amphiphilic molecules in a selective solvent for A and C blocks were studied using Monte Carlo simulation. For the purpose of comparison, H-bonding and covalent bonding were introduced via the two ends of two B bl…
An experimental investigation was performed to investigate the effect of a split-injection strategy on the combustion and exhaust emission characteristics as well as on the particle number distribution for a single-cylinder compression ignition engine with gasoline–dimethyl ether dual fuelling. The gasoline–dimethyl e…
The UV-induced photochemical grafting of terminal alkenes has emerged as a versatile way to form molecular layers on semiconductor surfaces. Recent studies have shown that grafting reactions can be initiated by photoelectron emission into the reactant liquid as well as by excitation across the semiconductor band gap,…
Abstract We report theoretical and experimental investigations of the flow instability responsible for mushy-layer convection with chimneys, drainage channels devoid of solid, during steady-state solidification of aqueous ammonium chloride. Under certain growth conditions a state of steady mushy-layer growth with no f…
In addition to beneficial ∼3 orders of magnitude in the resistance ratio, the amorphous HoScOx film exhibits excellent resistive switching (RS) properties of low electrical stress, thin thickness (36 nm), and simple process without forming or annealing, making it potentially useful for nonvolatile memory applications.…
The exchange bias (EB) effect and its thermal stability in nanoscale Co/NiO antidot arrays and sheet films have been investigated. The EB field HE increases with increasing Co thickness (tCo) and reaches a maximum at tCo = 8 nm in the antidot arrays, whereas HE decreases with tCo in the sheet films. Compared with the…
We analyze the accuracy of the frozen density embedding (FDE) method, with hybrid and orbital-dependent exchange-correlation functionals, for the calculation of the total interaction energies of weakly interacting systems. Our investigation is motivated by the fact that these approaches require, in addition to the non…
BACKGROUND: This study was done to obtain concentrated polyunsaturated fatty acid (PUFA) linoleic acid (LA; 18:2) and monounsaturated fatty acid (MUFA) oleic acid (OA; 18:1) from Jatropha curcas seed oil by urea complexation. Urea complexation is a method used by researchers to separate fatty acids (FAs) based on thei…
RhodamineB (RB) dye-doped TiO2-SiO2 core-shell composite microspheres were synthesized by a chemical method from the hydrolysis of the titanium tetrachloride (TiCl4). The morphology and chemical bonding information of composite material was investigated by transmission electron microscopy (TEM), scanning electron micr…
Fresh-cut green bell peppers (Capsicum annuum L.) were stored in modified atmosphere packaging (MAP) made of impermeable high-density polyethylene film. Two in-packaging atmospheres and storage temperatures (0 oC and 5 oC) were tested. The respiration rate of the unpackaged produce and the in-package gas concentration…
