The ability of a protein to carry out a given function results from fundamental physicochemical properties that include the protein's structure, mechanism of action, and thermodynamic stability. Traditional approaches to study these properties have typically required the direct measurement of the property of interest,…
The magnetic energy levels of a given magnetic solid are closely packed in energy because the interactions between magnetic ions are weak. Thus, in describing its magnetic properties, one needs to generate its magnetic energy spectrum by employing an appropriate spin Hamiltonian. In this review article we discuss how…
We report a catalyst made of Pd nanoparticles (NPs) supported on mesoporous N-doped carbon, Pd@CN(0132), which was shown to be highly active in promoting biomass refining. The use of a task-specific ionic liquid (3-methyl-1-butylpyridine dicyanamide) as a precursor and silica NPs as a hard template afforded a high-nit…
The mechanisms by which carbon nanotubes nucleate and grow are still poorly understood.Understanding and mathematically describing the process is crucial for its optimization.This paper reviews different models which have been proposed to explain carbon nanotube growth in the chemical vapor deposition process.The revi…
We proposed a novel anisotropic soft-core potential for spherocylinders that takes into account the degree of overlap between two spherocylinders, thus superior to other soft-core spherocylinder models depending only on the minimum distance between two line segments representing spherocylinders, for example, that used…
Electromagnetic wave propagation in one-dimensional disordered structures composed of hyperbolic metamaterials is theoretically investigated. We find that the disordered system can suppress Anderson localization of light at long-wavelength limit under a finite range of incident angle. For isolated frequencies and for…
The interaction between graphene layers is analyzed combining local orbital DFT and second order perturbation theory. For this purpose we use the linear combination of atomic orbitals-orbital occupancy (LCAO-OO) formalism, that allows us to separate the interaction energy as the sum of a weak chemical interaction betw…
We study the infinite-energy solutions of the Cahn-Hilliard equation in the whole 3D spacein uniformly local phase spaces. In particular, we establish the global existence of solutions for the case of regular potentials ofarbitrary polynomial growth and for the case of sufficiently strong singular potentials. For thes…
In this study, the effect of nanoclay and carbon black on the curing system of styrene-butadiene rubber (SBR)/butadiene rubber (BR) and natural rubber (NR)/BR blends were investigated. The dispersion of nanoclay and carbon black in blends was studied under the x-ray diffraction and scanning electron microscopy. Interc…
We study the scattering properties of very small spheres made of a negative refractive index (NRI) using circuit network principles. The Lorenz-Mie theory is used to represent the transverse magnetic and transverse electric scattering coefficients based on resistor, inductor, and capacitor (RLC) ladder circuit models…
The small-signal power gain of Si quantum dots embedded in a Si-rich SiOx(SiOx:Si-QD)-based ridge waveguide amplifier with an inhomogeneously broadened spontaneous emission is analyzed and simulated. The small-signal power gain and the direct bandgap radiative recombination rate of SiOx:Si-QD waveguide amplifier are l…
In this article, morphology of progesterone polymorphs prepared by polymer-induced heteronucleation (PIHn) technique was studied. Hydroxypropyl methylcellulose(HPMC), such as dextran T-500 and gelatin G-9382, polyisoprene (PI), and acrylonitrile/butadiene copolymer (NBR) were used as substrates. The crystallizations w…
= -- - (4) By assuming that the standard thermodynamic entities of the intra-crystalline reaction are equal to zero, i.e., o r ,298 0 = , the standard values of the molar thermodynamic entity of the hydration water, ( ) f Hyd HO 0 ,298 2 , is finally obtained from eqs (2) and (4):
A series of oxygen deficient LuFe(2)O(4-δ) materials have been prepared under a controlled oxygen partial-pressure atmosphere. Measurements of magnetization reveal that the increase of oxygen deficiencies could evidently depress the ferrimagnetic phase transition temperature (T(N)). In additional to the well-known cha…
Titanium- and silicon-modified novolac (TSN) resins were prepared by the reaction of novolac resin with the organotitanium polysiloxane. TSN resins with a series of inorganic element contents were prepared, and the corresponding silicon fiber reinforced TSN composites (TSN/silica fiber) were fabricated by the compress…
In this letter, we study the low-frequency noise behavior of RESET-state Phase-Change Memory (PCM) devices belonging to a 45-nm technology node. Furthermore, by dealing with a typical case study, we calculate the fluctuation of the cell readout current induced by$\hbox{1}/f$noise and provide predictions for estimating…
Nanostructured thin films of a mixed-valence, layered vanadium oxide were prepared using layer-by-layer deposition. The thin films were characterized by electronic (UV–vis) spectroscopy, quartz crystal microbalance, profilometry and scanning electron microscopy techniques. The highest charge capacity was obtained for…
A new scaling formalism is used to analyze nonlinear I-V data in the vicinity of metal-insulator transitions (MIT) in five manganite systems. An exponent, called the nonlinearity exponent, and an onset field for nonlinearity, both characteristic of the system under study, are obtained from the analysis. The onset fiel…
The preparation of monodisperse nanoparticles with uniform size, shape and composition has been intensively pursed because of their scientific and technological interests [1-4]. The major advantage of monodisperse particles may be attributed to the uniform properties of individual particles, which makes the property o…
The photoelastic constant (PEC) is evaluated for 15 zinc tin phosphate glasses in a series of xZnO-(67-x)SnO-33P(2)O(5) where x is 0-30 mol. % at 0.5-7 mol. % intervals. The phase retardation of polarized light, passing through a disk sample with applying various uniaxial loads, was measured for PEC determinations by…
