Security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. For this reason, security is always of managers, planners, architects and urban designers' interest. Solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes and h...

stability of the π-π stacking interactions in the ben||substituted-coronene and hfben||substituted-coronene complexes was studied using the computational quantum chemistry methods (where ben and hfben are benzene and hexaflourobenzene, || denotes π-π stacking interaction, substituted-coronene is coronene molecule which substituted with four x groups, and x= nh2, ch3, oh, h, f, cf3, cn and no). ...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

The interest in the synthesis of metallic complexes of different drugs to make them moreefficient in biological environment of the human body is seen for the last few decades. Widerange of metal complexes are already used in clinical practice which encourages additionalresearch for innovating new metal based drugs, such as metal-mediated antibiotics, antiparasitic,antiviral, antibacterial, and ...

In this study, the role of interaction of pi electrons on the strength of simultaneous σ-hole interactions (pnicogen, chalcogen and halogen bonds) is investigated using the quantum chemical calculations. X-ben||TAZ∙∙∙Y1,Y2,Y3 complexes (X = CN, F, Cl, Br, CH3 , OH and NH2, TAZ= s-triazine and Y1,Y2 and Y3 denotes PH2F, HSF, and ClF molecules) is introduced as a model. The results show that inte...

A series of dissymmetric dinuclear complexes were synthesized, as dual site catalysts in ethylene polymerization, by coupling the allylated a-diimine complexes of the metals Ti, Zr, V, Ni and Pd with the ansa-zirconocene complex [C5H4-SiH(Me)-C5H4]ZrCl2 possessing a hydride silane moiety. The different stages of syntheses included the formation of bis(cyclopentadienide)methyl silane which was u...

the antimicrobial activity of some novel ascorbic acid-metal complexes [bisascorbate complexes of copper (ii), zinc(ii), manganese (11), iron (111), cobalt(ii), lead(ii) and cadmium(ii)] was investigated. four standard strains of bacterial species - staphylococcus aureus, escherichia coli, bacillus subtilis and klebsiella pneumonia and four fungal species - trichophyton sp. penicillium sp., asp...

the objectives of this experiment were to investigate the application of new ligands including different atoms & evaluation their nucleophile effects against various metals. chemistry researchers are really interested in this field. from among various ligands, there are some ligands with different coordinating ligands as well. there are great number of intermediate complexes and major eleme...
