Gold nanorods stabilized by binary ligand mixtures of cetyltrimethylammonium bromide (CTAB, primary ligand) and ascorbic acid or hydroquinone were investigated complementary synchrotron radiation-induced spectroscopies microscopies, with the aim...

A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhed...

The phenomenon of molecular binding, where two molecules, referred to as a receptor and ligand, bind together form ligand-receptor complex, is ubiquitous in biology essential for the accurate functioning all life-sustaining processes. probability single forming complex with any one L surrounding ligand molecules at thermal equilibrium can be derived from partition function obtained Gibbs-Boltzm...

Cell adhesion on a supported lipid bilayer (SLB) functionalized with ligand proteins is widely-used cell-mimetic model for the study of trans receptor-ligand interaction that mediates adhesion, and has been shown to play an important role in unravelling molecular players cell adhesion. Experimental studies such cell-SLB systems often assume there no cis interactions between ligands. An question...

A new theory of ligand-receptor bonds in biological cells that accounts for membrane fluctuations reveals an orders-of-magnitude increase binding rates and the range over which a receptor can recognize its ligand.

a pvc membrane ni(ii) ion selective electrode has been constructed using (1e,2e)-bis(2-aminophenyl)n'1,n'2-dihydroxyethanebis as membrane carrier. the electrode exhibited a goodpotentiometric response for ni(ii) over a wide concentration range 1.0×10-4 to 1.0×10-1m with aslope of 29.4±0.5 mv/decade a and a working ph range of 6.5-9.0. it had a fast response time of≤20s. the best performance was...

synthesis and cation selectivity of 25, 27, dipropoxy-26, 28, di-propoxy 5, 11, 17, 23, ptert-butyl calix[4]arene are studied in acetonitrile solution. the stability constants of differentcomplexes of calixarene (as a ligand) with alkali metal cations are determined at 25 °c by usingspectrophotometric technique.on the basis of calculations, complexation of calixarene with cs+and li+ are more fa...

the present work describes the studies on the coordination behaviour of 4[n-(benzalidene) amino]antipyrine semicarbazone (baaps) (i), 4[n-(furfural)amino]antipyrine semicarbazone (ffaaps) (ii) and 4[n-(cinnamalidene)amino]antipyrine semicarbazone (caaps) (iii) in presence of dimethyl sulfoxide (dmso) or diphenyl sulfoxide (dpso) towards th4+ and uo22+ salts. all the complexes were isolated in n...
