Effects of Structure and Partially Localization of the π Electron Clouds of Single-Walled Carbon Nanotubes on the Cation-π Interactions
A C102H30 graphene sheet has been rolled up to construct Single-Walled Carbon NanoTube Fragments (SWCNTFs) as parts of armchair carbon nanotubes by computational quantum chemistry methods. Non-covalent cation-π interactions of the Na+ cation on the central rings of SWCNTFs have investigated. The binding energies of the Na+-SWCNTF complexes versus ...
متن کاملCation–π–cation interactions in structural biology
Biological structures are stabilized by a variety of noncovalent interactions, such as hydrogen bonds, π –stacking, salt bridges or hydrophobic interactions. Besides hydrogen bonds and π– stacking, cation–π interactions between aromatic rings and positively charged groups have emerged as one of the most important interactions in structural biology. Although the role and energetic characteristic...
متن کاملthe role of thematic structure in comprehending spoken language
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
15 صفحه اولProtein crystal growth. Growth kinetics for tetragonal lysozyme crystals.
A method for immobilizing protein crystals has been devised for determining face growth rates, and used to investigate the growth kinetics of hen egg white lysozyme crystals. Growth rates were determined at 22 degrees C in 0.1 M sodium acetate, 5% NaCl, pH 4.0, on the visually identified (110) face of tetragonal lysozyme crystals. Protein concentrations ranged from 13 to 57 mg/ml (saturation co...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
