Local Atomic Structure Analysis Using the Atomic Pair Distribution Method
Powder diffraction is a major component of any condensed matter scientist’s arsenal, providing the investigator a way to directly map the location of atoms inside of a material. The most common diffraction experiments provide insights into the average atomic structure of materials, which can break down when materials have lowered local symmetry, or are disordered. Analysis of the pair distribut...
متن کامل- Atomic Spectra Atomic Structure
T HE present edition of this work contains a number of corrections and additions; Birge's new set of fundamental constants has been adopted throughout, and various tables, especially the table of ionization potentials, have been brought up to date. The author is indebted to Professor J. W. Ellis of the University of California at Los Angeles for a list of errors and corrections ; several of the...
متن کاملresponse articles: micro and macro analysis
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
15 صفحه اولQTAIM study of Bonding and Structure of Pure Atomic Clusters,Part III : Nn Clusters (n= 4,6)
DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...
متن کاملKnudsen Spectrum and Time-of-Escape Analysis of Surface Structure
We propose a theoretic framework for studying gas transport in the Knudsen regime, starting from a hard sphere model of the gas-surface collision, without making a priori assumptions about the Fickian nature of the process. A fundamental signature of the gas-surface interaction, which we call its Knudsen spectrum, is introduced. We isolate the geometric feature of the surface influencing diffus...
