This paper reports on the non-traditional corrosion method for the synthesis of hematite mesocrystals in the size range of 30 μm. The results clearly show that the self-assembly of hematite mesocrystals were consisted of many small building units which were densely packed. The formation mechanism for hematite mesocrys…
The crystallographic structure of spherical viruses is modeled using a multiscale approach combining a macroscopic Helfrich model for morphology evolution with a microscopic approximation of a classical density functional theory for the protein interactions. The derivation of the model is based on energy dissipation a…
A dual-band reflectarray antenna with a double layer, employing concentric square rings as reflecting elements, is proposed. With a procedure of the steepest decent method (SDM), the impressed phases of the reflecting elements are synthesized for the proposed antenna to radiate an optimum field pattern in the near zon…
The Fe-doped TiO2nanocomposites synthesized by a deposition-precipitation method were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and UV-vis adsorption spectra and then were taken as a new “photosensitizer” for photodynamic therapy (PDT). Th…
In this work we investigate the potential of inline single side wet-etch processing for rear side emitter removal and edge isolation for large area p-type Passivated Emitter and Rear (PERC) silicon solar cells. We focus on the integration of this process in flows leading to shallow emitters and screen printed front co…
In this paper the friction and wear characteristics of vinylester and cenosphere reinforced vinylester composites have been investigated under dry sliding conditions, under different applied normal load and sliding speed. Wear tests were carried using pin on a rotating disc under ambient conditions. Tests were conduct…
We investigated the rock-soil transition zones of three different Terra Rossa profiles near the ancient site of Abila, in northern Jordan, in order to demonstrate the possibility of a metasomatic origin for these soils using a scanning electron microscope (SEM) equipped with an energy-dispersive system (EDS). The fiel…
With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. Pharmaceutical formulation development involves various components in addition to the active pharmaceutical ingredients. The plant derived gums and mucilages comply with many r…
The goal of this study was to introduce a method for estimating stress analysis as an efficient procedure for evaluating the strength of mitered corner joints in furniture structures. Tests were carried out to determine the effects of panel type, distance between the centers of dovetail holes and the edges of joints (…

The present paper established a three-dimensional finite element model of the double-shouldered tool joint,and analyzed mechanical behaviors of the tool joint under make-up torque,axial tension and bending moment by means of the explicit dynamic finite element method.Compared with a two-dimensional axisymmetric model,…
Moonlighting is the capability of some proteins to execute two or more biological functions. According to some authors, there is a relationship between protein conformational fluctuations and promiscuous functions of proteins. This promiscuity would be due to the conformational properties of the structurally disordere…
Gold particles have been used in complementary medicine for decades, and many beneficial effects have been reported. Our present study sought to evaluate the therapeutic effects of nanogold in carbon tetrachloride (CCl₄)-injured liver of rats. Male SD rats were subjected to liver injury induction by CCl₄, then the rat…
The antibacterial reaction rate kt (CFU/g-hr) and total antibacterial capacity qT (CFU/g) were calculated to evaluate the performance of antibacterial Ag-zeolite (AgZ) with a series of experiments. The continuous antibacterial reactions at 10 and 80 hr were respectively repeated nine times to evaluate the AgZ antibact…
To understand phosphorus release from low-grade rock phosphates (PRs) by low-molecular weight organic acids (LMWOAs) and the factors influencing P release from PRs, we investigated the characteristics of P release from two low-grade PRs, selected from Baokang and Zhongxiang, Hubei province of Central China, using seve…
Bamboo culms were processed using microorganisms, and fibre bundles were obtained. Bacteria and fungi with xylanase activity were isolated from the bamboo retting system. Chemical composition analysis of the fibre bundles obtained showed that the components are mainly cellulose, hemicelluloses and lignin. An increase…
Nanostructuring Materials towards Conventionally Unachievable Combination of Desired Properties When the size of a particle or the size of grains in a solid is reduced to the nanometer scale, unusual changes in its properties may occur. For example, a nano-sized particle of silica could be electrically conductive whil…
The purpose of this research was to determine the shelf life of minimally processed (MP) 'Pérola' pineapples treated with ascorbic acid (AA) and citric acid (CA) based on physical, chemical, sensorial and microbiological attributes. Slices were dipped into drinking water (control) or combined solutions of AA:CA (%) (1…
Solid dispersions have been employed to enhance the dissolution rates of poorly water-soluble drugs. Many approaches have been investigated for the preparation of solid dispersions. This paper reports the various solubility enhancement strategies in solid dispersion. The approaches described are fusion (melting), solv…
The synthesis of a thiourea substituted derivative of tris(pyridyl-2-methyl)amine (TPA) is reported. Two of the three pyridine rings are substituted in the 6-position with benzoylthiourea groups. These thiourea groups undergo intramolecular hydrogen bonding to form six-membered rings which leaves one N-H group availab…
