Abstract The influence of different modes and types of electrolytic plasma treatment has been studied regarding the morphology of the structure, the phase composition and the mechanical properties of the surface of 18CrNi3Mo low-carbon steel. It is shown that the result of electrolytic-plasma treatment (EPT) is the fo…
Rubrene layers with thickness comparable to a visible light wavelength on silver thin film exhibit anomalous photoluminescence (PL) spectra that depend strongly on emission angle. The PL properties demonstrated for rubrene (500 nm)/Ag (50 nm) were modulated from yellow green to red luminescence with an increasing emis…
In recent years, sandwich structures have been considered as viable engineering constructions. The use of composite structures in aerospace and civil structural applications have been increasing especially due to their extremely low weight that leads to reduction in the total weight , high flexural and corrosion resis…
Molecular dynamics simulations were performed to clarify the nanomechanical responses of β-Si3N4 nano-thin layers in the basal plane for indenters of various radii, different indentation velocities and at different temperatures. It was found that the maximum loading stress and indenter displacement both increase with…
The evolution of mankind from Paleolithic Era to the current big Era Nine has also found versatile applications of various plastic polymers owing to some desirable properties like mechanical strength, poor electrical and thermal conductivities and as a result, subsequent generation of its wastes are thriving up. Basic…
Combustion process was studied from the injection until the late combustion phase in an high swirl optically accessible combustion bowl connected to a single cylinder 2-stroke high pressure common rail compression ignition engine. Commercial diesel and blends of diesel and n-butanol (20%: BU20 and 40%: BU40) were used…
Desde la obtención experimental del grafeno en el 2004, los sistemas cristalinos bidimensionales han sido objeto de un profundo estudio tanto teórico como experimental. Los métodos de análisis de la estructura electrónica han abarcado desde el tight binding, la ecuación de Dirac para los puntos K y K’ hasta los método…
Abstract Hybrid complexes based on a D‐π‐A type dye p‐aminostyryl‐pyridinum cation and a lanthanide(III) complex anion were synthesized by ionic exchange reaction. Different alkyl‐substituted amino groups were used as electron donors in organic dye cations. The synthesized complexes were characterized by elemental ana…
Three nickel thiosemicarbazone mixed ligands complexes have been synthesized. Complexes with the formula [NiL(PPh3)]Cl, [Ni2L2(Phen)],[Ni2L2(Bpy)] (where L= 2,3,4-trihydroxybenzaldehydethiosemicarbazone, PPh3=Triphenylphosphine, Phen=1,10-phenanthroline, Bpy= 2,2 –Bipyridine)have been characterized by IR spectroscopy,…
This study has encountered with the fabrication of ferrites (Mg and Mn) using citric acid as anionic surfactant in sol-gel method followed by calcinations at varied temperatures (300, 600, 800°C) for 2h, respectively. The fabricated ferrites have been characterized by FTIR (Fourier Transform Infrared Spectroscopy), XR…
In this present work the influence of Cenosphere filler material in thermal and mechanical properties of Epoxy resin is discussed. For comparative study, pure resin and composites made with different compositions (1, 3 and 5 wt% of Cenosphere) were prepared. The specimens were submitted to thermal analysis (DMA) and m…
Investment casting process has been a widely used process for centuries. It is known for its ability to produce components of complex shapes with dimensional accuracy and excellent surface finish. Investment casting has been used to make manufacture weapons, jewellery and art castings during the ancient civilization a…
Thermally and gas-induced transformations of the well-known host compound 4-tert-butylcalix[4]arene result in mixed porous phases. The coexisting mixed porous phases of 4-tert-butylcalix[4]arene selectively absorb air components N2, O2 and CO2.
Abstract We demonstrate a new doping technique for chemical vapor deposition (CVD) growth of diamond. The method involves immersing a solid-state dopant source into the plasma during microwave plasma-assisted CVD. We applied this simple and versatile technique to the growth of boron-doped diamond. The grown films were…
Single crystals of ${\mathrm{Sc}}_{x}$${\mathrm{Ti}}_{1\ensuremath{-}x}\text{OCl}(x=0.005)$ have been grown by the vapor phase transport technique. Specific heat measurements prove the absence of phase transitions for 4--200 K. Instead, an excess entropy is observed over a range of temperatures that encompasses the in…
LPG is a mixture of gas, mainly propane and butane. It is commonly used as a fuel for cooking and as a transportation fuel. It is normally created as a by-product of petroleum refining and from the production of Natural Gas. An experiment is conducted to obtain the operating characteristics of the four stroke three cy…
Synthesized ZnO nanotubes have finite wall thickness and holy hexagon section. Using density functional theory first we calculated structural and electronic properties of isolated and bundle of these systems. Then same calculations are performed for these systems which encapsulated Fe nanochain or Fe nanowires with di…
Bionic self-cleaning surfaces with well-ordered polymer nano-fibers are firstly fabricated by disturbing crystallization during one-step coating-curing process. Orderly thin (100 nm) and long (5-10 μm) polymer nano-fibers with a certain direction are fabricated by external macroscopic force (F blow) interference intro…
