This paper deals with 1-N-methyl-cinnoline TCNQ complex(1-N-M_(ci) TCNQ_2) and 2-N-methyl-cinnoline TCNQ complex(2-N-M_(ci) TCNQ_2). The molecular packing analyses of both complex crystals were performanced by using. OPEC program.
Supramolecular Assemblies of a Novel Dinuclear Cu(II) Complex via π-π stacking and Hydrogen Bonding Interactions: Synthesis and Crystal Structure of [Cu_2 (phen)_2 (OH) Cl(C_4H_4O_4)]. 8H_2O (phen = 1, 10-phenanthrolne)
In combination with other ordinary loggings feature,the fine division of strata in mixed accumulational sandstone/gravel stone with complex diluvial-alluvial-fan delta facies was finished,which laid good foundation for geologic research on adjustment of reservoir development scheme.
Considering the kinds of exogenic forces,thier directions and history of geomorphic development, seven geomorphologic genetic types are concluded as 1) accumulational, 2)accumulation-denudational,3)accumulation - erosional and denudational, 4) denudation - accumulational ,5) denudational and erosional , 6)erosional and karst and 7)erosional.
Excessive accumulation of intracellular sorbitol found in various tissues of diabetic animals and in cells cultured under high glucose conditions has been proposed to be an important factor for the pathogenesis of diabetic complications.
Aldose reductase inhibitors have been found to prevent sorbitol accumulation in tissues.
This paper discusses a general kind of increasing annuity based on its force of interest accumulation function as a general random process.
This method is implementable and globally convergent without assuming the strict complementarity condition, the isolatedness of accumulation points.
In particular, this method is implementable and globally convergent without assuming the strict complementarity condition and the isolatedness of accumulation points.
Simultaneous introduction of multiple genes into plants is a critical step in plant genetic engineering to manipulate multiple functional genes in metabolic engineering and trait stacking.
Twinning plays important roles in HCP metals and those FCC metals with low stacking fault energy.
It is found that there were high-density dislocations and stacking fault substructure in the Cu clusters that forms the obstacle of the dislocation motion, which should be the dominant reason of strengthening in the Fe-Cu alloy.
This indicates that a stacking-type mechanism underlies actinomycin intercalation into DNA.
The reason for its appearance was considered to be either the formation of a charge transfer complex between ThDP and tryptophan (phenylalanine) residue or stacking interaction between the residues of aromatic amino acids.
