ABSTRACT A continuous melt suspension crystallization process has been presented for the purification of the phosphoric acid in this study, which is conducted in the cascade of a continuous mixed suspension and mixed product removal (MSMPR) crystallization and subsequent countercurrent solid–liquid contact in a gravit…
Pure tin oxide films were deposited onto glass substrate at different oxygen flow rates by a simple and inexpensive method of air pressure chemical vapor deposition. The deposition temperature was kept constant at about 500 °C, and oxygen with a flow rate of 0–400 sccm was used as both a carrier gas and the oxidizing…
Neutron reflectivity (NR) measurements of ultrathin surface films (below 30 nm) composed of Bombyx mori silk fibroin protein in combination with atomic force microscopy and ellipsometry were used to reveal the internal structural organization in both dry and swollen states. Reconstituted aqueous silk solution deposite…
We present on a systematic study of the contribution of surface plasmon (SP) coupling and light extraction toward emission enhancement of Platinum (Pt) nano-patterns capped MgZnO films. Time resolved Photoluminescence (PL) results indicate that the Pt coating can greatly reduces the non-radiative recombination rate by…
The preparation procedure of epoxy and benzoxazine multi-walled carbon nanotube buckypaper composites is described. The morphology of the buckypaper is characterized by scanning electron microscopy and porosimetry, revealing a non-uniform porous structure. The wetting behavior of epoxy and benzoxazine resins in the bu…
Dehydration enthalpy and dc conductivity obtained by means of thermogravimetric analysis and complex impedance spectroscopy respectively on three alkaline-earth, i.e. Mg 2+, Ca 2+, and Ba 2+, exchanged montmorillonites with low water loading are reported. These data are compared with those previously reported on the s…
A quadripolymer scale inhibitor, IA-SSS-MA-MAA, was prepared by a free radical solution polymerization with itaconic acid (IA), styrene sulfonic sodium (SSS), maleic anhydride (MA), and α-methyl acrylic acid (MAA) as monomers and ammonium persulfate as initiator. The chemical structure of the quadripolymer was investi…
The electronic band structures, partial and total spin density of states of Cr, Fe, Mn and Ni doped β-Ga 2 O 3 are studied. It is shown that there exists only one spin polarized state around the Fermi level for all doped β-Ga 2 O 3 . Ferromagnetism is predicted for Mn and Ni doped while spin-glass ground states are pr…
We investigated thin La${}_{0.7}$Sr${}_{0.3}$MnO${}_{3}$-SrTiO${}_{3}$ heterostructures, where the band alignment is engineered by a variation of La/Sr stoichiometry only at the interface. In thin films, the engineered interface leads to an enhancement of the reversed spin configuration that mimics bulk behavior. Micr…
This paper reviews and discusses the mechanical loads that overhead lines experience as defined by applicable codes and the strength requirements for insulators that support the lines as described in ANSI, CSA, and IEC standards. Consideration of the probable occurrence of extreme weather conditions requires the insul…
Five compounds were isolated from the root powder of Periploca sepium. By mainly HR-ESI-MS, (1)H, (13)C, and 2D NMR spectral data, they were characterized as periplocoside X (1), oligasaccharide A (2), periplocoside A (3), periplocoside E (4), and periplocoside N (5), respectively. Compounds 1-5 were found to possess…
Abstract: Spray forming UHCS-1.6Al material has a refined equiaxed pearlitic structure, which was necessary for high-train-rate superplasticity. During deformation, the cementite particles pin the grain boundaries and prevent the grains growing up. As a result it exhibited excellent high-strain-rate superplasticity, w…
By using generalized gradient approximation (GGA) scheme within the density functional theory (DFT), the electronic and magnetic properties of Hg 2 CuTi-type Heusler alloy Ti 2 FeAl were investigated. The results reveal that a 100% spin polarization appears at Fermi level (εF) in Ti 2 FeAl, and is maintained during la…
6063 aluminum alloys are used as the luggage rack’s material on high-speed trains recently. The study on the AZ31B magnesium alloy is aimed to demonstrate the feasibility of the magnesium alloy’s application as the material of the luggage rack on high-speed trains. First, the mechanical properties of the AZ31B magnesi…
Summary Over the years, environmental legislation has forced changes in the types of scale-inhibitor molecule that can be deployed in certain regions of the world. These regulations have resulted in changes from phosphonate scale inhibitor to polymer-based chemistry, particularly in the Norwegian and UK continental sh…
Crystalline selenium nanostructures were synthesized from the reaction of a GeSe3 glass with water at 85°C for 144 hours. The hydrolysis of the Ge-Se bonds releases Se fragments in the solution where they form a colloidal suspension of amorphous nanospheres. The later evolve toward a more stable hexagonal phase (trigo…
We seek to identify universal properties shared by all quantum systems with large intrinsic second hyperpolarizability (γint)—an invariant quantity that removes the effects of simple scaling. A large-γint quantum system is generated by varying the shape of a trial potential until γint is optim…
Helical nanomaterials with superelasticity have a wide range of promising applications in micro-/nanoelectromechanical systems. Based on the theory of surface elasticity, we present a nonlinear rod model to investigate the superelasticity of nanohelices. Our results demonstrate that the superelasticity of nanohelices…
Artificial transmission lines based on lattice network unit cells can mimic the behavior of actual metamaterial transmission lines without introducing any stopband, as opposite to their conventional counterparts based on T- or II-network unit cells, which can be balanced to suppress the stopbands in the transitions fr…
In this paper we describe the preparation and characterization of magnetic nanocomposites designed for applications in targeted drug delivery. Combining superparamagnetic behavior with proper surface functionalization in a single entity makes it possible to have altogether controlled location and drug loading, and rel…
