The poly(3-hexylthiophene):-phenyl C61-butyric acid methyl ester(P3HT∶PCBM) bulk-heterojunction polymer solar cells fabricated with doctor-blade coating were studied.It is found that the active layer thickness increases with increasing the coating speed or lowing substrate temperature,which is attributed to the change…
The Cu-30wt%Ag alloy nanopowders are prepared by induction plasma technology, and the nanopowder is successfully coated by terpineol (C10H18O). The morphology, phase composition and oxidation resistance of nanopowders are characterized by scanning electron microscopy (SEM), X-ray diffraction and thermogravimetric (TG)…
For the study of solution heat treatment characteristic of spray-formed FGH4095 after near iso thermal forging, the superalloy specimens, which have been hot isostatically pressed (HIPed) and forged with a 75% compression ratio, are solution heat treated at 1120℃, 1140℃ and 1160℃ for 10, 20 and 40 min respectively, an…
In this paper, Cu-0.41wt.%Cr-0.21wt.%Zr alloy is subjected to an isochronal aging treatment with a DC electric current (100A/cm2) and a static magnetic field simultaneously imposed. The alloy in the form of plate with a thickness of 2 mm is solid-solution-treated and cold deformed with a total area reduction of more t…
The elastic properties of the β-HMX under an extra pressure are studied from density functional theory calculations using the projector augmented wave method. The calculated bulk modulus and shear modulus under zero pressure are 12.7 GPa and 4.4 GPa which are in good agreement with the available experimental results.…

The application of melt quenching for the production of high-strength heat-treatable Al-Zn-Mg-Cu aluminum alloys is considered. The complex multifactor mechanism of hardening of these materials is explained on the basis of their structure and mechanical properties, and a quantitative estimation of individual hardening…
In this paper a modified up-quenching heat treatment method (Tomita method) for AISI 4340 steel (ultra high strength steel) is proposed. A low alloy steel (0.33%C), was used to study the effect of isothermal austempering and modified up-quenching austempering heat treatment on the mechanical properties. The specimens,…
The MIMAC project aims to provide a nominal fluorine detector for directional detection of galactic dark matter recoil events. Its expected behavior reaches an important part of the predicted spin dependent elastic scattering interactions of the supersymmetric neutralino with protons. Hence, the parameter space in the…
This paper presents a new multi-criteria stabilization algorithm of transformer differential protection. Proposed scheme bases on new criteria signals and appropriate operation thresholds. New algorithm employs fuzzy reasoning technique for better discrimination of inrush conditions. The developed stabilization algori…
The convergence of the finite element method in a stable smoothing algorithm for solving a model problem with given friction based on an iterative proximal regularization of the modified Lagrangian functional is analyzed. Numerical results are presented.
The formalism of generalized diffraction integral for paraxial misaligned optical systems is used to investigate the propagation of the Modified Bessel-Gaussian (MBG) beam through a misaligned thin lens. The properties of the propagation of MBG beam traveling through this misaligned ABCD optical system are discussed.…
The use of plasma for super smooth surface polishing is well established in the microelectronic and optical industry. In this paper the polishing effects of RF-generated plasma were investigated using a capacitively coupled plasma apparatus. During the polishing of silica substrate, a mixture of SF6, O2 and Ar plasma…
In this study, an optimation growth of platinum (PtNs) and palladium (PdNs) nanoparticles has successfully grown on stainless steel 316L and activated carbon pellet as substrates. PtNs and PdNs were grown on the substrates by wet chemical method. The effect of concentration of ascorbic acid and multi-growth step had s…
At the J-PARC muon science facility (J-PARC/MUSE), a graphite target with a thickness of 20 mm has been used in vacuum to obtain an intense pulsed muon beam from the RCS 3-GeV proton beam [1], [2]. In the current design, the target frame is constructed using copper with a stainless steel tube embedded for water coolin…
A theoretical and numerical investigation of tunable plasmonic nano-optic lens on the basis of liquid crystal are proposed as a new method of active modulating the output beam. The focal length can be controlled easily by exposing plasmonic nano-optic lens to constant external electric field. The physical principle of…
The fibre reinforced concrete, which is defined as a composite material consisting of a material of cement mortar or concrete and discontinues discrete, uniformly distributed fibres has gained a wide popularity in the construction industry. The introduction of fibres into the concrete induces many desirable properties…
Epitaxial Si and Gd2O3 Heterostructures: Distributed Bragg Reflectors with Stress Management Function for GaN on Si Light Emitting Devices, Dargis, R., Clark, A., Arkun, E., Roucka, R., Williams, D., Smith, R., Lebby, M.
To solve the problem of salivate,an unsteady phenomenon caused by the mismatch of feed velocity and high-voltage in the electrospinning to fabricate nanoscale fibers,this paper proposes an on-line monitor system based on the multi-featured pattern recognition for realizing both the stability of nanofiber manufacturing…
No#ceably less moisture, eschar, and bacterial growth were present in the Drawtex-‐treated burn site compared to the control on both Days 3 and 4. In vitro studies showed that by thirty minutes post Drawtex submergence, bacterial growth significantly increased in the Drawtex that was submerged in MRSA culture, while…
