In this research at the Adenine tautomers and their fullerene derivatives were optimized. NBO calculations and NMR for the tautomers and their Fullerene derivatives were carried out at the B3lyp/6-31G*quantum chemistry level. The core and the valence electrons of atoms were compared. Other cases examined in this study, resonance energy, chemical potential (µ ),...

At the base of Shemshak Formation in the south Azadshahr area, some igneous mafic rocks are discovered recently  as olivine gabbro bodies and pegmatoid alkali-diorite dikes. Rock-forming minerals of olivine gabbro includes olivine, clinopyroxene and plagioclase, alkali-diorites are composed of large amphiboles and plagioclase. Major and trace elements characteristics of these rocks indicate the...

Aiming to facilitate the analysis of human genetic variations in the context of disease susceptibility and varied drug response, we have developed a genotyping method that entails incorporation of a chemically labile nucleotide by PCR followed by specific chemical cleavage of the resulting amplicon at the modified bases. The identity of the cleaved fragments determines the genotype of the DNA. ...

Chirality transfer is an interesting phenomenon in Nature, which represents an important step to understand the evolution of chiral bias and the amplification of the chirality. In this paper, we report the chirality transfer via the entanglement of the alkyl chains between chiral gelator molecules and achiral amphiphilic Schiff base. We have found that although an achiral Schiff base amphiphile...

Bonding agents are important components in solid propellants which affect processing, mechanical, ballistics, safety and aging properties of propellant. In this research, we have synthesized and characterized three types of new polymeric bonding agents by post functionalization of glycidyl azide polymers (GAP) via click chemistry. The interaction of new bonding agents with the surfaces of RDX p...

Chromium and molybdenum are intermediate elements of a periodic table group, both of which are both low but essential in nutrition because they play a key role in the metabolism of the chemical activity of the body. Anion analysis of these compounds in order to compare the properties of the elements of the periodic table in one The group is from the periodic table. In this paper, the quantum ch...

The goal of the Biomolecular Simulation of Base Excision Repair and Protein Signaling project is to enhance our understanding of the mechanism of human polymerase-β, one of the key enzymes in base excision repair (BER) and the cell-signaling enzymes cyclic-AMP-dependent protein kinase. This work used molecular modeling and simulation studies to specifically focus on the • dynamics of DNA and da...

[1] Climate warming and permafrost degradation at high latitudes will likely impact watershed hydrology, and consequently, alter the concentration and character of dissolved organic carbon (DOC) in northern rivers.We examined seasonal variation of DOC chemistry in 16 streams of the Yukon River basin, Alaska. Our primary objective was to evaluate the relationship between source water (shallow ve...

Acidic deposition leads to the acidification of waters and accelerated leaching and depletion of soil base cations. The Bear Brook Watershed in Maine has used whole-watershed chemical manipulations to study the effects of elevated N and S on forest ecosystem function on a decadal time scale. The objectives of this study were to define the chemical and physical characteristics of soils in both t...
