The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand  Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...

A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...

An efficient synthetic method for successful synthesis of amine denderon on SBA-15 and related Pd (II) complex has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N2 adsorption-desorption, and FT-IR. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of al...

The ability to dissipate large fractions of their absorbed light energy as heat is a vital photoprotective function of the peripheral light-harvesting pigment-protein complexes in photosystem II of plants. The major component of this process, known as qE, is characterised by the appearance of low-energy (red-shifted) absorption and fluorescence bands. Although the appearance of these red states...

Singlet-singlet annihilation experiments have been performed on trimeric and aggregated light-harvesting complex II (LHCII) using picosecond spectroscopy to study spatial equilibration times in LHCII preparations, complementing the large amount of data on spectral equilibration available in literature. The annihilation kinetics for trimers can well be described by a statistical approach, and an...

nowadays, the subject of vision metrology network design is local enhancement of the existing network. in the other words, it has changed from first to third order design concept. to improve the network, locally, some new camera stations should be added to the network in drawback areas. the accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...

A novel ternary Schiff base ligand (HL) of ONO type and its copper (II) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. They have been characterised by theusual analytical and spectral methods. The interaction of the complex with calf-thymus (CT)DNA has been investigated by UV-Vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. The re...
