... amount of BNKT and BST powders was weighed, ball-milled for 24 h, and dried using the oven-drying method. BNKT and BST powders were separately calcined for 2 h at 900°C for BNKT and 1,100°C for ... reduction of T c was observed in our system. At room temperature, ε r of pure BNKT was found to be 1,419. The addition of 10 mol% BST showed an optimum ε r of 1,609. As f...

... objective of this paper is twofold. First, we investigate the initial stages of nucleation, oxi- dation of Zn atoms, and growth of ZnO nanowires. Secondly, we investigate the formation of tapered ... rgy minimization is the criterion to be satisfied for the for- mation of the nucleus. After the nucleus is formed, ZnO nanowires start to form, as shown in Figure 1d, e for t =...
