Abstract:
We report a statistics-based electron Moiré method in this study, for the first time, to cope with the highly distorted fringes and to realize the measurement of disordered mesoporous structures. A grey-level co-occurrence matrix is employed to determine the predominant period and the orientation of a randomly distributed Moiré fringe pattern and consequently to obtain the corresponding period/orientation of the test structures. The basic principles, the method descriptions, and the relevant experiments are discussed in detail. Mesoporous alumina films are investigated with the proposed method.

Electronic Structure of Atoms
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...

Probability in Statistics
An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...
