embedded in an insulating material. This system, assumed to a series of flattened cylindrical quantum dots with a finite barrier at the boundary, is studied using the triangular potential. The electronic states and the effective mass of 1 miniband have been computed as a function of inter-quantum dot separation for di…
Photocatalytic oxidation has grown to be very impressive technique in dealing with environmental pollutions 1-3 . A number of published literatures have reported the satisfactory future both on fundamental theory and applicable research in this field. The development of new photocatalytic materials with high activity…
The environmental and economic concerns have lead to the development of a number of management techniques to handle the waste polymers. Although recycling is considered as one of the most feasible solution to cater the plastic waste yet it is not implemented widely due to high cost involved in the process. Polyethylen…
Our group has recently developed novel nano-sized drug carriers that spatially target a tumour and release their payload in the presence of ultrasound-induced inertial cavitation. To maximize drug release and distribution within the tumour, co-localisation of the drug carrier and cavitation nuclei is necessary. We hav…
The Al2O3 nanoparticles were prepared by in situ-modified method and modified with KH-560. The particle size analysis confirmed that the mean particle size of modified Al2O3 nanoparticles was 90 nm and its distribution was uniform. The dispersion of modified Al2O3 nanoparticles was analyzed by the absolute value of Al…
Microcracking susceptibility in the dissimilar multipass weld metal of alloy 690 and low-alloy steel A533B was evaluated, and the effect of dilution on hot cracking (ductility-dip and liquation cracking) behavior was investigated. In order to simulate the dissimilar multipass weld metal of alloy 690 to A533B steel, th…
The Advanced High-Temperature Reactor (AHTR) is a 3400 MWth fluoride-salt-cooled high-temperature reactor (FHR) that uses TRISO particle fuel compacted into slabs rather than spherical or cylindrical fuel compacts. Simplified methods are required for parametric design studies such that analyzing the entire feasible de…
According to IPCC reports, the greenhouse gas CO2 is responsible for global climate change. Studies show that CO2 concentration reached a level of 400 ppm in 2013, or 40 % above pre-industrial levels. The contribution of CO2 from industrial activity to increasing global CO2 concentrations is widely accepted and points…
Lateral constrain in the presence of melting has a significant effect on microstructure evolution of crystal growth, and this effect is related to the size and property of lateral constrain, thus determining microstructure formation during solidification. In the paper, microstructure evolution in the presence of later…

Eu 3+ -activated tungstate phosphors, Ca9Gd2-xEuxW4O24 (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, 2.0), were prepared by the conventional solid-state reaction method. A systematic and exhaustive study for their photoluminescent properties was made. The tungstate phosphors show intensely red emission under 39…
In the field of packaging, barrier layers are functional films, which can be applied to polymeric substrates with the objective of enhancing their end-use properties.For food packaging applications, the packaging material is required to preserve packaged food stuffs and protect them from a variety of environmental inf…
Cyclic load could result in the fatigue failure of a component at stress levels below the yielding stress of material. Therefore, studying the mechanical behaviors of a dental implant structure under cyclic load is required. The numerical modeling of a cyclic load test was performed for a bio-compatible dental implant…
Stellite 6 powders were deposited on low carbon steel using SLD (supersonic laser deposition) under optimized parameters. The structure, line scan of elements and porosity of coating were examined and analyzed using SEM (scanning electron microscope), OM (optical microscope) and XRD (X-ray diffraction). The adhesion s…
The improvement of hole-expansion properties for medium carbon steels by ultra fast cooling (UFC) after hot strip rolling was investigated.It was found that finely dispersed spherical cementite could be formed after ultra fast cooling , coiling and annealing treatment.Tensile strength of the steel after annealing was…
Cu(Ⅱ) detection is important because it plays crucial role in several biological processes and ecological systems.Fluorescent techniques have attracted more and more attention in Cu(Ⅱ) detection.In this report,we contribute a novel strategy to use fluorescence spectroscopy for Cu(Ⅱ) specific detection.The specificity…
Based on the 2-D motion model of bullet penetrating gelatin,a function of the drag coefficient,the lift coefficient,the roll moment coefficient and the yaw damping torque coefficient derivative which is related to the bullet shape is established.Based on the 7.62mm bullet,five kinds of bullets were designed for the pe…
This paper reports on the effects of film thickness and doping content on the optical and electrical properties of fluorine-doped tin oxide. Tin(II) chloride dehydrate, ammonium fluoride dehydrate, ethanol and HCl were used as the starting materials, dopant source, solvent and stabilizer, respectively. The doped films…
The elastic, electronic and thermodynamic properties of the superconducting ErNi2B2C material at high pressure are investigated using the plane-wave pseudopotential density functional theory. The analysis shows the dependences of the elastic constants, bulk modulus, shear modulus, Young's modulus and elastic anisotrop…
The magnetism, stabilities and phase transition of Ru in hcp, fcc, bct and bcc structures are investigated with detailed first-principles calculations based on density-functional theory and quasiharmonic lattice dynamics approximation. Magnetic ground states and stability ranges of various phases are obtained. Calcula…
