新的前沿打开不同的方向内更高和更深的知识结构使用失业纳米尺寸域。BaTiO_3等陶瓷材料具有分形结构的本质是基于这三种现象。首先，陶瓷颗粒具有分形形状，在横截面上看起来像轮廓或表面。第二，存在由孔隙和粒间空间构成的所谓“负空间”。第三，在烧结期间和之后，材料内存在分形布朗运动（fBM），其形式为微粒流：离子、原子和电子。在这里，我们承担了通过分形性质校正来扩展Coble模型的任务，该模型已经推广了欧几里得几何。这三个因素使非常特殊的微电子环境静电/动态组合。这里的重点是设置在更高的能量收集和存储功能的颗粒间微容量上。构造性分形理论允许识别具有分形电极的微电容器。该方法基于与晶粒模型本身兼容的插值迭代过程。颗粒间渗透率被视为温度和焓（吉布斯自由能）的基本热力学参数函数，这对结构-能量关系非常重要。
The new frontiers open different directions within the higher and deeper knowledge structure using unemployed nano sizes domains. The BaTiO3 and other ceramic materials have fractal configuration nature based on three phenomena. First, ceramic grains have fractal shape looking as a contour in cross section or as a surface. Second, there is the so-called “negative space” made of pores and intergranular space. Third, there is fractal Brownian motion (fBm) within the material, during and after sintering, in the form of microparticle flow: ions, atoms, and electrons. Here, we took upon ourselves the task of extending Coble’s model, with already generalized Euclidean geometries, by fractal nature correction. These triple factors make the very peculiar microelectronic environment electro-static/dynamic combination. The stress is here set on inter-granular micro-capacity in function of higher energy harvesting and storage. Constructive fractal theory allows identifying micro-capacitors with fractal electrodes. The method is based on the iterative process of interpolation which is compatible with the grain model itself. Inter-granular permeability is taken as the fundamental thermodynamic parameter function of temperature and enthalpy (Gibbs free energy), which are very important for a structure-energy relation.
