Many biomolecules contain photoactive reducing agents, such as reduced nicotinamide adenine dinucleotide (NADH) and 6-thioguanine (6-TG) incorporated into DNA through drug metabolism. These reducing agents may produce reactive oxygen species under UVA irradiation or act as electron donors in various media. The interac…
MgO-coated SnO 2 films were prepared on plastic substrate (polyethylene naphthalate coated with indium-doped tin oxide, ITO/PEN) by the electrophoretic deposition (EPD) technique and mechanically compressed. Dye-sensitized solar cells (DSSCs) were fabricated with plastic MgO-coated SnO 2 photoanodes, which showed a ma…
One of the utmost challenges of hot aluminum extrusion is to design the die cavities with sharp corners (used to extrude thin-walled profiles) by considering the effective nitriding surface treatment of the die bearing surface in terms of nitride layer uniformity. In the present study, various AISI H13 steel samples (…
The Lennard-Jones (LJ) potential has been widely used, even beyond fluid science, as a standard form to express interparticle interaction. However, numerical computation and simulation requires some convention for dealing with the potential's infinite tail. This delicate problem can be circumvented by adopting a trunc…
The effect of microwave heating (MWH) on the isothermal kinetic of crosslinking-polymerization of acrylic acid (CPAA) was investigated. The kinetic curves of CPAA were determined in the temperature range from 303 to 328 K. By applying the model-fitting method it was revealed that the isothermal kinetics of CPAA was de…
We analyze whether and how the neutron resonance mode in unconventional superconductors is affected by higher-order corrections in the coupling between spin excitations and fermionic quasiparticles and find that in general such corrections can not be ignored. In particular, we show that in two spatial dimensions ($d=2…
The states of water-soluble complexes of zinc phthalocyanine containing -O-C 6 H 4 -COONa and -NH-C 6 H 4 -COONa substituents in aqueous and organic media are studied. The type of dimerization is determined for each phthalocyanine. Phthalocyanine interaction with bovine serum albumin is studied with respect to the ass…
We investigated the feasibility of producing high strength Al alloy sheets with high solute contents using a twin roll strip caster equipped with an asymmetric nozzle. The combination of twin roll casting and the asymmetric nozzle used in this study reduced centreline segregation and hot tear, thereby increasing the c…
In this study, the moisture resistance properties of self-bonded plywood were enhanced by thermal modification. The plywood was prepared without any adhesive, using only heat, moisture and mechanical compression. It is known that self-bonded plywood or the wood welding joints suffer from delamination under moist condi…
Scanning electron microscopy, focused ion beam (FIB), and transmission electron microscopy are combined to study the intergrowth of 90° rotational components and of ramps in coffin-shaped ZSM-5 crystals. The 90° rotational boundaries with local zig-zag features between different intergrowth components are observed in…
New type synthetic methods of InVO4 photocatalysts for visible light driven high photocatalytc activity are much desired. In this study, the InVO4 nanocrystals with the size of ∼25 nm photocatalysts were successfully synthesised by a facile microwave hydrothermal method. The obtained photocatalysts exhibit the excelle…
A hybrid nanostructure, which consists of multi-walled carbon nanotubes (MWCNTs) and nitrogen-doped carbon encapsulating SnO2 nanoparticles is synthesised as the anode material for lithium ion batteries to improve the initial coulombic efficiency and cycle stability of the SnO2-based anodes. For the N–C@SnO2/MWCNTs co…
Nanosecond laser produced brass plasmas are studied at the ambient pressures of 10 −3 , 20, 100 and 500 Pa. Spatial and temporal dynamics of the plasmas are captured by fast photography and optical emission spectroscopy (OES). The phenomena of plasma free expansion, splitting, sharpening, and instability are observed,…
A facile heating cell has been designed for in situ transmittance and fluorescence X-ray absorption spectroscopy (XAS) measurements up to 1273 K under vacuum or an inert atmosphere. These high temperatures are achieved using a tantalum heating element by ohmic heating. Because of the small specific heat capacity, the…
A potential fluorescent zinc(II) sensor was synthesized and its spectral profile was studied in aqueous solutions of increasing zinc(II) concentrations. Due to the inherent properties of its chromophore, the sensor exhibits a “turn on” response in solutions of nanomolar zinc(II) concentrations that turns to ratiometri…
Abstract In this study, the effects of thixoforming, both equal channel angular pressing (ECAP) and thixoforming on high cycle fatigue and fatigue surface morphology of AA7075 have been examined. Experiments are carried out with the same sample materials (AA7075) at a constant temperature (483 K) and the ``C'' route f…
Density functional theory calculations with van der Waals approximation have been conducted to analyze the functionalization of various carbon-based nanostructures (fullerene, metallic, and semi-conducting nanotubes) with amino derivative groups. The results obtained with azomethine, show the formation of a five membe…
The objective of the work is to investigate the effect on the distribution of chloride at different depths of some factors concerning concrete pore structure, namely water/cementitious material ratio, cement type and percentage ground granulated blast furnace slag (GGBS). Concrete cubes are subjected to repeated wetti…
The present results showed that in Al&hyphen ;Si alloys, Sr modified (SrM), superheat (SH) and SrM melt thermal treatment (SrMTT) processed castings provide fine eutectic Si particles, with the SrMTT process giving the best modification results. Both size and morphology of the eutectic silicon particles are affected b…
Abstract Trihalogenoruthenium(III) complexes bearing an ethylbis(2‐pyridylmethyl)amine (ebpma) ligand, fac‐[RuIIIX3(ebpma)] (X = Cl, Br), were reduced by zinc in acetone that contained halogeno acid to afford a reddish‐orange solution. Two kinds of dinuclear complexes were synthesized from the solution. After removing…
