Purification and functionalization of multiwalled carbon nanotubes (MWCNTs) are challenging but vital for their effective applications in various fields including water purification technologies, optoelectronics, biosensors, fuel cells, and electrode arrays. The currently available purification techniques, often compl…
Theoretical calculations of mass attenuation coefficients, partial interactions, atomic cross-section, and effective atomic numbers of PbO-based silicate, borate, and phosphate glass systems have been investigated at 662 keV. PbO-based silicate glass has been found with the highest total mass attenuation coefficient a…
The effect of flow rate on the diameter of the charged jet in the electrospinning process is studied theoretically. The obtained theoretical results offer in-depth physical understanding and mechanism of nanoporous fibers. It also reveals that the morphology and diameter of nanoporous microspheres can be controlled by…
. Therefore, this nanoscale control of silk offers feasible way to regulate the matrix features including porous structure and nanostructure, which are important in regulating cell and tissue outcomes in tissue engineering and regeneration, and then achieve silk-based scaffolds with improved properties.
Simple synthesis of a ferrocene-functionalized polydopamine [poly(DA-Fc)] is described. This redox film displays excellent electrocatalytic oxidation of H <sub>2</sub> O <sub>2</sub> in neutral buffer solutions in a Fenton-type reaction, and is found to be selective to H <sub>2</sub> O <sub>2</sub> with negligible int…
A sustainable nitrogen- and oxygen-doped carbon sheet was prepared from pigskin for supercapacitors with high capacitance and excellent rate capability.
All-conjugated block copolymers are an emerging class of polymeric materials promising for organic electronic applications, but further progress requires a better understanding of their microstructure including crystallinity and self-assembly through micro-phase segregation. Here, we demonstrate remarkable changes in…
Cisplatin is one of the most common anticancer agents for treating different kinds of solid tumors today. However, its broader therapeutic applications are limited by the severe side effects and nonspecific biodistribution. In this study, luteinizing hormone-releasing hormone (LHRH)-targeted polysaccharide nanoparticl…
The catalytic effects of CoFe <sub>2</sub> O <sub>4</sub> nanoparticles on the hydrogen storage properties of LiAlH <sub>4</sub> prepared by ball milling were investigated.
This paper presents the experimental evaluation of a recently developed model for predicting the maximum pit size possible on a stainless steel surface under a certain set of atmospheric conditions. Prediction of the maximum pit size possible on 304L and 316L was accomplished by coupling the maximum cathode current av…
The results of studies of thinning free water-in-oil emulsion films stabilized by solid particles by the Applied Pressure Drop Technique (APDT) are reported. The quasi-equilibrium film thickness achieved by slow increasing the pressure drop was smaller than the rupture thickness obtained by sharp increasing the pressu…
An attempt has been made in the present work to develop blend based mixed ion-electron conductor viz. PVA: PVK: CH3COONH4: EC system. Formation of polymer blend and composite has been evidenced during XRD and IR studies. Ionic conductivity of this system is seen to improve by an order of magnitude at room temperature…
Gamma uranium-molybdenum alloys have been considered as the fuel phase in plate type fuel elements for material and test reactors (MTR), due to their acceptable performance under irradiation. Regarding their usage as a dispersion phase in aluminum matrix, it is necessary to convert the as cast structure into powder, a…
In atomistic modeling of fracture, most examinations are based on the Griffith energy, calculated from the surface energy, and the stress intensity factor derived from continuum mechanical formulations. Both approaches, however, reflect continuum mechanics and lack the direct connection to the atomistic crack tip mech…
Two different phenomena may affect average molecular weight (Mw) of molten polyethylene during extrusion process. The first is crosslinking, which can be divided to two categories of chain branching and network formation, leading to an increase in Mw. The second is chain scission which leads to a decrease in the avera…
Polyester composites reinforced with natural lignocellulosic fibers have attracted interest in several engineering areas due to their low cost, low energy consumption during fabrication in association with a number of possible applications. One of these applications is the replacement of traditional composites such as…
Pesolar graphite grains exhibit a range of densities (1.65 -2.20 g/cm 3 ). We investigated abundances of presolar graphite grains formed in supernovae and in asymptotic giant branch (AGB) stars in the four density fractions KE3, KFA1, KFB1 and KFC1 extracted from the Murchison meteorite to probe dust productions in th…
A new and effective yield criterion and strain hardening rule for orthotropic materials such as wood are presented. The specific stresses, the ratios of stresses to the corresponding yield stress and called as the non-dimensional stresses in this study, are introduced in the principal axes of anisotropy, and the prese…
NH₃-SCR has high NOx removal efficiency approximately 80~90%. Recently, the copper or iron ion-exchanged zeolite catalysts are widely used as automobile SCR catalysts. In this paper, the effect of the space velocity, temperature of reaction and NO₂ addition on the NH₃-SCR reaction were studied using various zeolite SC…
