The growth behavior,electronic structures and magnetic properties for NinAl(1-8,12)clusters were investigated detailedly using the selected density functional method(BPW91/LanL2DZ).
The reduction kinetics of ilmenite was investigated.Phase evolution during the reduction process was identified by XRD and morphology change was observed using SEM.
The phase stabilityand site preference of LaFe13-xTx(T= Ga,Ni.Mn,Cr,Cu)are studied by using inter-atomic potentials based on Chens lattice inversion technique.
Recent developments in nanochemistry offer precise morphology control of nanomaterials,which has significant impacts in the field of heterogeneous catalysis.
The anthracite is deashed by calcined at 1100-1700℃,and the change of specific surface area and carbon microcrvstalline structure during the process is studied.
