Mn-Zn ferrite nanoparticles were prepared by a template-assisted sol-gel method and calcined in different atmospheres at different temperatures.The effects of calcined atmosphere and calcined temperat
LiInO2 photocatalytic materials were prepared by sol-gel method using In(NO3)3·4.5H2O, CH3COOLi·2H2O, deionized water and hexyl alcohol as raw materials.The properties of the samples were studied by X
Magnesium oxide aerogels were made by sol-gel process using magnesium methoxide as precursor, methanol and deionized water as solvent followed by supercritical drying with respect to ethanol.The influ
Hydroxyapatite (HAP) and calcite (CAL) particles are bioactive materials and can promote the mineralization of hard tissue in oral cavity, having broad application in oral care products.This in vitro
Engineering structures are often designed and optimized to meet multiple and possiblyconflicting objectives such as the minimum weight and maximum strength.The merit of multiobjectiveoptimization is t
In this paper,we consider an S-shaped piecewise linear supply function and the totaldemand which consists of two components,the real demand and the speculative demand,andthen develop a piecewise linea
In this paper,combination of cubic nonlinearity and time delay is designed to improve theperformance of a viscoelastic isolation system with a power-form restoring force.Based on themethod of multiple
