The diagnosis and treatment of cancer have been greatly improved with recent developments in bio-nanotechnology, including engineering of multifunctional probes. One of the promising nanoscale tools for cancer imaging is fluorescent quantum dots (QDs), whose small size and unique optical properties allow them to penet…
The purpose of this paper is to investigate the effect of the axial air-gap eccentricity (AAGE) on the electromagnetic characters such as the axial unbalanced magnetic pull (UMP) and the electromagnetic torque (EMT). Firstly, the theoretical model of AAGE is set up, and the formulas of the axial UMP and EMT are deduce…
The exhaust gas of marine diesel engine loses a lot of energy when the exhaust discharged directly. Making good use of diesel engine exhaust gas to generate electricity is helpful to improve the thermal efficiency. Supercritical carbon dioxide cycle is not only with high cycle efficiency, but its devices have advantag…
Effective anti- P. acnes using near infrared light is made possible by perfecting the matching between absorption wavelengths of the loaded photosensitizer and emission wavelengths of the upconverting nanoparticles with high UVA/visible emissions.
This advance is concerned with reactivity improvements of hydrating systems, based on fluidized bed combustion wastes, toward ettringite.
Chitosans with high and low molecular weight were intercalated into organic rectorite to prepare nanocomposites via a microwave irradiation method for 75 min, which was much more efficient than the conventional 48 h heating method.
Here we report on the improved field emission performance of graphene foam (GF) following transient exposure to hydrogen plasma.
Ti-doped lithium vanadium(III) phosphate cathode materials, Li3−2x(V1−xTix)2(PO4)3, were prepared by a solid state reaction. The Ti-doped samples exhibited that the γ-phase is stabilized at room temperature by substituting Ti for V sites at more than x = 0.10. The discharge capacity of the doped samples at a 60 C rate…
Palladium nanoparticles were dispersed on the surface of poly (diallyl dimethyl ammonium chloride) - mesoporous carbon (Pd/PDDA-MC) composite as a catalytic for the environmental hormones nonylphenol (NOP) electrochemical oxidation. The Pd/PDDA-MC was characterized by transmission electron microscope (TEM), scanning e…
Oil Palm Empty Fruit Bunch (OPEFB) was pretreated using Deep Eutectic Solvent (DES) at different parameters to enable a highest yield of sugar. DES is a combination of two or more cheap and safe components to form a eutectic mixture through hydrogen bond interaction, which has a melting point lower than that of each c…
In this research the interaction between oxygen molecules and the outside and inside surfaces of pristine and Ge-doped (4,4) armchair and (6,0) zigzag models of aluminum phosphide nanotubes (AlPNTs) was systematically investigated using density function theory. Structural parameters, adsorption energy, quantum paramet…
Thermally reduced graphene oxide transforms regular paper from hydrophilic to hydrophobic.
Results of testing methodology for calculating two-phase flows based on the method of fluid in the cells (VOF method), and the procedure for CSF accounting of surface tension forces in the microchannel are considered in the work. Mathematical modeling of two-component flow fluid -fluid in the T- microchannel conducted…
Subject of this work is the development of a simple and cost-efficient process for conditioning the surface of forming tools for deep drawing processes in order to minimize friction and wear to a level that dry forming processes without any lubricants will be possible in future. The approach chosen is an oxidative hea…
Palygorskite/polyacrylamide (PAM) composited thickeners were prepared via in-situ polymerization. To optimize the preparation, the dependence of the viscosity, rheological properties and electrolyte resistance of the composited thickeners on the initiator concentrations, sodium hydroxide concentrations and palygorskit…
We develop a quantitative model to calculate the optimal experimental conditions for the etching of the oxide barrier of porous anodic alumina (PAA) membranes. The method is applied to a membrane fabricated at 370 V in a solution of 2% citric acid. The process creates a network of small pores at the bottom of the larg…
For an analysis of the oxidation behavior of UO2 nuclear fuel pellet under a loss of water coolant accident in a spent nuclear fuel pool of an LWR, thermodynamic assessments of UO2 oxidation were carried out under various atmospheric conditions. In a steam atmosphere, it was assessed that UO2 would not be fully oxidiz…
The crystal structure and magnetic properties of the compound Na5[Mn(l-tart)2]·12H2O (1, l-tart = l-tartrate) have been investigated over the pressure range 0.34-3.49 GPa. The bulk modulus of 1 has been determined as 23.9(6) GPa, with a compression of the coordination spheres around the Na(+) ions observed. 1 is there…
In this paper an effort has been made to study the effects of ageing variables on the abrasive wear behavior of Aluminium 6061 alloy and Silicon Carbide particulate reinforced Aluminum 6061 Composites. The composite material was prepared by using stir casting technique. The as-cast material was heat treated by a metho…
A chemical bond includes both covalent and ionic characteristics. We develop an experimental method to estimate the degree of each contribution based on magnetic susceptibility measurements, in which Pascal's scheme for Larmor diamagnetism is combined with electronegativity. The applicability to metal hydrides is also…
