This paper is mainly to discuss that myclobutanil as corrosion inhibitor and its corrosion efficiency were evaluated via electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. The potentiodynamic polarization measurements showed that the inhibition efficiency increases sharply with the increasi…
The microstructural and technological properties of clay ceramic incorporated with 10 and 20 wt% of elephant grass ashes were investigated at different firing temperatures of 650, 850 and 1050oC. X-ray diffraction were used to obtain the minerals and phase compositions. The microstructure was analyzed by scanning elec…
Polyacrylamide (PAM) was chemically anchored to the surface of multi-walled carbon nanotubes (MWCNTs) by atom transfer radical polymerization (ATRP) of acrylamide (AM). It started from the functional groups such as –COOH on the sidewall of MWCNTs, which derived from the oxidation of carbon nanotubes. FT-IR and 1H NMR…
Zero-field muon spin rotation/relaxation (μSR) measurements were performed in order to clarify the effect of oxygen reduction and Ce-substitution on magnetic properties in T’-structured Pr1.40-xLa0.60CexCuO4+δ−α. At 75 K, a clear rotation signal was observed in the three samples; as-sintered x = 0 and annealed x = 0,…
In this paper conceptual design study of modified CANDLE burn-up scheme based 400 MWt small long life Pb-Bi Cooled Fast Reactors with natural Uranium as Fuel Cycle Input has been performed. In this study the reactor cores are subdivided into 10 parts with equal volume in the axial directions. The natural uranium is in…
The concept and design of terahertz (THz) digital phase shifter based on graphene Gate-controlled Switchable Devices (GSD) with Defected Ground Structures (DGS). It is shown that the graphene based Unit Phase Shifter (UPS) may enable viable applications of gate controlled switchable devices for THz wideband antenna sy…
In this research, FINEMET alloy with composition of Fe73.5Si13.5B9Nb3Cu1was produced by mechanical alloying from elemental powders. The effect of milling time on the magnetic and structural properties of alloy has been investigated using X-ray diffraction, scanning electron microscopy, transmission electron microscopy…
A Sn oxide layer on the surface of Sn solder balls plays an important role in the semiconductor packaging industry. This paper shows a comprehensive analysis of the Sn oxide layer by XPS depth profiles. The distribution of Sn with different oxidation states can be derived from curves fitting Sn3d5/2 peaks. Moreover, t…
Two dimensional semiconductors and especially MoS2have gained a lot of attention due to their unique properties. Finite bandgap, large Ion/Ioffratio, good mobility, and nearly perfect subthreshold slope are among some of the features that make these materials attractive to researchers. While electrical transport has b…
Abstract In this work, high-quality cypress-like Au dendrites were successfully synthesized by a fast, green, and cost-effective method. Time-dependent morphological evolution experiments revealed the growth process. The as-prepared Au dendrites with nanoscale roughness exhibited both excellent surface-enhanced Raman…
An overview of modification of cerium oxide, CeO2which is employed in the three-way catalyst (TWCs) is presented in this article. The modifications of cerium oxide, CeO2incorporated with the metal oxides for the improvement of thermal stability, microstructure and oxygen storage capacity (OSC) are discussed. In view o…
The effect of a weak permanent magnetic field on the structure and charge state of silicon for solar-power engineering is investigated. It is revealed that magnetostimulated changes in the defect-impurity state and surface potential have a reversible character.
A generalized folded transformation procedure is presented for the space with arbitrary shapes. General expressions for the constitute parameters of complementary media are deduced, which can be readily applied to design complementary media based transformation optics devices (CMTOD) with arbitrary shapes. It's no lon…
Last level cache (LLC) is crucial for the performance of chip multiprocessors (CMPs), while power is a significant design concern for 3D CMPs. In this paper, we focus on the SRAM-based Non-Uniform Cache Architecture (NUCA) for 3D Multi-core Network-on-Chip (McNoC) systems. A tightly mixed SRAM NUCA for 3D mesh NoC is…
The elastic property and sound velocity of Fe3C under high pressure are investigated by using the spin-polarized generalized gradient approximation within density-functional theory. It is found that the magnetic phase transition from the ground ferromagnetic (FM) state to the nonmagnetic (NM) state occurs at ∼73 GPa.…
Equilibrium melt polycondensation was used to synthesize a series of oligoethers containing end hydroxy groups, starting with hydroxyethylated derivatives of 4,4′-(propan-2,2-diyl)diphenol and saturated aliphatic dicarboxylic acids. The structure of the oligoethers was assigned, and their physicochemical characteristi…
At present, there are still drilling soft velvet jacket fabric, breathable, coated thick and many other issues, the clothing brand's lack of guidance on the technical parameters of the purchase fabric, so that the domestic high-end brands in soft single layer anti-velvet products domestic market share is far behind fo…
Nanodielectrics have attracted the attention of many scientists and industrials as they may present superior dielectric properties compared to conventional dielectric composites. However, the success of these materials relies on a proper dispersion of the nanofiller within the matrix. In this work, the efficacy of hex…
This paper presents the results of thermal ageing of paper oil insulation at 140° C when DBDS and mercaptan sulphur are present in oil. It discusses the effects of simultaneous presence of DBDS and mercaptan sulphur at higher temperatures. It is observed that DBDS and Mercaptan sulphur increase copper corrosion. Diele…
The design, synthesis and characterization of magnetic-luminescent nanoparticles is now more and more studied since the last decade.
