Representative material

This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method.

Lightweight structures with soft inclusion material, such as hollow core slabs, foam sandwich wall, pervious pavement are widely used in construction engineering for sustainable goals. Voids and soft inclusion can be modeled as a very soft material, while the main material is modeled with its original rigidity, which is so much higher than inclusion’s one.

Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.

By using kaolin A Luoi (Thua Thien Hue province) and the necessary materials, the blue pigment with different shades in the cordierite lattice have been synthesized. The blue pigment will be enamelled with a transparent glaze on to ceramic tile and L*, a*, b* colour parameters of representative samples were measured with a colorimeter.

Glycosylatedpolyenemacrolide antibiotics, as nystatins and amphotericins, are amphiphilic structures known to exert antifungal activity by disrupting the fungal cell membrane, leading to leakage of cellular materials, and cell death. This membrane disruption is strongly influenced by the presence and the exact nature of the membrane sterols.

The increasi1ng level of heavy metals in the water environmental represents a serious threat to human health and ecological systems. These contaminants must be removed from water resources. Various treatment technologies have been developed. In this paper, the potential of removing heavy metals from aqueous solution by using porous aluminosilicate was studied. The solid sorbents were synthesized by reaction of sodium silicate and alumino sulfate with sol-gel method.

In this chapter, we will find out how to get the most solar energy out of the sun by considering the time, the altitude angle, the radiation and the photovoltaic (PV) materials. A simple PV model helps to understand the mechanism of energy conversion - solar to electricity. We will further use a simple equivalent circuit to represent a PV cell to investigate its current-voltage characteristics.
