A facile method is described for synthesizing quasi-cotton fiber and spherical nickel nanostructures via a thermal reduction of Ni(acac)2 (acac = acetylacetonate) in N,N-dimethylformamide (DMF) and in the presence and absence of sodium thiosulfate, respectively. XPS analysis revealed the existence of Ni(2+) and SO4(2-…
Catenane structures, in which two or more rings are mechanically interlocked, have historically occupied one of the central places in the field of supramolecular chemistry. In contrast to synthetic small-molecule catenanes, examples of naturally-occurring catenanes are scarce. Here, we report thermodynamic and enzymat…
A simple and a very convenient solution combustion method have been described to obtain ZnO nanoparticle. The band gap energy, particle size and morphology were studied by absorption spectra, XRD and SEM. The photocatalytic activity of synthesized ZnO nano particle on Brilliant red dye was studied by varying pH, amoun…
The enormous area of damage to Japan's Fukushima Daiichi nuclear power plant requires radiation detectors with robust base substrates to monitor high-dose-rate environmental radiation with long-term stability. Undoped aromatic ring polymers have considerable potential as base substrates in radiation detection. Here, w…
Cobalt oxide and composite thin films were synthesized by spin-coating technique, followed by heating to 500°C in oxidizing, inert, or reducing atmospheres. Methanolic solutions of triethanolamine complexes of cobalt acetates and nitrates were spin-coated at 1000, 2000, and 3000 rpm. The influence of heating parameter…
In this study, a hybrid ultrasonic and Fenton's reaction process (US/Fenton) was applied for oily sludge treatment. The impacts of four different factors on the reduction of total petroleum hydrocarbons (TPH) in oily sludge were investigated. These include the initial sludge content, the molar ratio of hydrogen peroxi…
Cylinder Four Stroke Diesel engine under the influence of magnetic field. The influence of magnetic field on the engine performance parameters such as specific fuel consumption, break thermal efficiency, exhausts emissions etc. by applying the magnetic field along the fuel line immediately before fuel injector. The st…
The present work illustrates the method of initial functions (MIF) to see the effect of elastic properties on the behaviour of the beam. Generally for beams, modulus of elasticity, shear modulus and Poisson’s ratio are the commonly used parameters, however in the present study, varied Poisson’s ratio has been consider…
In this paper, a method for multi-physics analysis of the temperature-dependent properties of an oil-immersed transformer is discussed. To couple thermal fields with electromagnetic and fluid fields, an algorithm employing a user defined function (UDF) is proposed. Using electromagnetic analysis, electric power loss d…
Surface tension plays a key role in splash generation. However, accurate modeling of surface tension is challenging due to the numerical difficulties in calculating the interface curvature. This paper presents a new surface tension model for macroscopic particle methods on the basis of Continuum Surface Force (CSF) co…
Treatment of a newly prepared digold(i) complex, [Au2(dppe)(H2msa)2] ([H41]; dppe = 1,2-bis(diphenylphosphino)ethane, msa = thiomalate), with Ni(2+) gave two interconvertible multinuclear complexes, [Ni{Au2(dppe)(msa)2}](2-) ([2](2-)) and [Ni3{Au2(dppe)(Hmsa)2}{Au2(dppe)(msa)2}(MeOH)3] ([3]), dependent on solution aci…
Preparation of side-aminated polyvinylpyrrolidones and their potential application as pH-sensitive drug-conjugate carriers.
The umbilical cord (UC) has recently been added to the list of potential cell sources for tissue engineering and regenerative medicine purposes. Although the UC is usually discarded after delivery, UC storage in special tissue banks is becoming an increasingly common procedure. Indeed, the capacity of UC cells to be d…
Membrane electrode assemble (MEA) design is one of the crucial component of MFC. Therefore, the MEA design is critical to improving MFC's performance. In this work, effects of the presence of the cathode microporous layers and the distance between anode and cathode electrodes on MFC's performance are investigated. The…
The composition and morphology evolution for Pt x Ni 1−x (0 < x < 1) nanoalloys was achieved by adjusting the growth kinetics, which were found different under different temperatures. The structure-dependent electrocatalytic performance was evaluated with MOR as the model reaction.

RTILs as media to synthesize a variety of nanomaterials are gaining momentum owing to their unique physicochemical properties. However, the fundamental questions regarding the role of the inherent structure of the IL in directing the morphology and the growth mechanism of the nanoparticles are still unexplored. Theref…
A four-channel multilayer Kirkpatrick-Baez (KB) microscope is developed for the 8-keV X-ray imaging of experiments on laser inertial confinement fusion (ICF). A periodic multilayer that works at 8 keV and with a grazing incidence angle of 1.0 is coated on reflective surfaces to achieve a spatial resolution higher than…
