In this study, effect of ball milling on the structural properties and bleaching performance of the Kerman bentonite sample was investigated.The bentonite sample consisted mainly of montmorillonite and small amount of impurities. The sample was ground with a high energy ball mill and characterized by X-Ray Diffraction…
Aluminum/Copper clad sheet has been fabricated using asymmetric extrusion method, which caused severe shear deformation between Al and Cu plate to easily bond to each other. Interfacial microstructure and mechanical properties of Al/Cu clad were studied by scanning electron microscope equipped with energy dispersive X…
High temperature corrosion via chlorine is a key factor in the degradation of boiler tubes in waste-to-energy (WTE) plants. Corrosion rates are particularly high in the superheater where material temperatures may exceed 450°C and where carbon or low alloy steels may be used. Although increasing sulfur, in the form of…
Emission regulations throughout the world continue to tighten, creating technical and economic challenges for various industries. The U.S. has proposed strict emissions limits that include mercury (Hg), particulate matter (PM) and a growing focus on NOx, while Europe is focusing more aggressively on reducing Nitrogen…
The gold colloidal nanoparticles was prepared by citrate reduction from chloroauric acid (HAuCl4·4H2O). An ITO glass was coated with nanoporous TiO2, Fe2O3 and ZnO by squeegee method. The squeezing coated films were loaded with Au-nanoparticles by depositing technique. The film was characterized by UV-visible transmit…
Recently proposed Quasi-Continuum Orbital Free Density Functional Theory (QC-OFDFT) is a seamless multi-scale scheme that has enabled the computation of electronic structure at macroscopic scales, and has paved the way for an accurate electronic structure study of defects in materials. It combines a real-space formula…
Introduction The backbone amide groups in peptides and proteins [1] are one of many endogenous compounds able to exhibit a chemical exchange saturation transfer (CEST) effect by exchanging protons with water molecules. The resonance frequency of the amide protons is situated at 3.6 ppm from the water resonance frequen…
Studying the optical and electronic properties of commercial hydrated EuCl 3 salts, we took advantage of the manifestation of the unfilled 4f valence shell in photoluminescence and core-level photoemission spectroscopies to unambiguously identify contributions from both Eu 3+ and Eu 2+ configurations. Lanthanide ion s…
INTRODUCTION: The development of approaches to increase drug solubility and partitioning into the skin is an active area of research in topical and transdermal delivery. In addition to forming spherical aggregates, e.g., conventional oil in water or water in oil microemulsions, the combination of an oil, surfactant an…
Pyrazole exhibits exceptional effects of temperature and pressure for H-disorder in hydrogen bonds NH···N. Under normal conditions, α-pyrazole is polar (orthorhombic space group Pna 2 1 ), but the structure is pseudo-centrosymmetric. Two symmetry-independent molecules differently favor the H-sites at their amine nitro…
Ethanol on TiO 2 (110) has been studied using the temperature-programmed desorption (TPD), femtosecond two-photon photoemission spectroscopy (2PPE), and density functional theory (DFT) calculations. The first layer of ethanol (binds to Ti 5c ) whose molecular state has been predicted to be more stable by DFT desorbs a…
The Mn-doped ZnS nanoparticles with Mn content of 0–15 mol% were synthesized by a hydrothermal method from the solutions Zn(CH3COO)2 0.1 M, Mn(CH3COO)2 0.01 M, and Na2S2O3 0.1 M at 220°C for 15 h. These nanoparticles presented the cubic structure with average particle size about 16 nm. The yellow-orange photoluminesce…
New York City (NYC) annually generates an estimated 750,000 short tons of municipal plastic waste (MPW), 84% of which is landfilled. This study examined the potential of using NYC’s non-recycled plastics (NRP) as feedstock for three pyrolysis processes developed in North America: the P2O process of JBI Inc., the Agily…
Quantitative analysis has been carried out in order to obtain more information about the structure of two glass systems, namely, (B2O3-MnO2-PbO) (BML glass system) and (B2O3-Na2CO3-P2O5) (BSP glass system). Their structural elucidation has been carried out by studying the ultrasonic velocities (longitudinal velocities…
Spatially resolved electron energy loss spectroscopy (SR-EELS) using scanning transmission electron microscope (STEM) allows the identification and determination of the spatial distribution of the components/elements of immuno-functionalized core-shell superparamagnetic magnetite nanoparticles. Here, we report that SR…
The use of gold nanoparticles as imaging agents and therapeutic delivery systems is growing rapidly. However, a significant limitation of gold nanoparticles currently is their low absorption efficiencies in the gastrointestinal (GI) tract following oral administration. In an attempt to identify ligands that facilitate…
The temperature at which the ferrite is sintered critically depends on the chemical composition. The electromagnetic properties are dependent on the densification and microstructure. Substitutions and addition of sintering aids is an attractive approach to enhance the electromagnetic properties. Various compositions i…
Nanoparticles have more propensities for amorphization than their bulk counterparts, opening the opportunity to achieve the amorphous states in well-known poor glass-former compounds. Classical size effects are often invoked to explain such phenomenon. However, this argument is not sufficient to cover all experimental…
Al ‐ and B ‐doped 3 C – SiC ceramics were prepared by hot‐pressing powder compacts containing submicrometer‐sized β‐ SiC , precursors of 5 wt% nanosized β‐ SiC , and an optional additive ( Al or B ) in an Ar atmosphere. Electron probe microanalysis ( EPMA ) investigation on the obtained specimens revealed that a porti…
This work focuses on the dynamical behavior of carbon nanotubes, including vibration, wave propagation and fluid-structure interaction. In the present research, transverse vibration of nano fluid conveying carbon nanotubes is investigated. To this end, based on the nonlocal and strain-inertia gradient continuum elasti…
