Modification of titania with copper is a promising way to enhance the photocatalytic performance of TiO2. The enhancement means the significant retardation of charge carriers’ recombination ratio and the introduction of visible light activity. This review focuses on two main ways of performance enhancement by copper species—i.e., originated from plasmonic properties of zero-valent copper (plasm...

Copper (II) phthalocyanine and 2,9,16,23 tetrakis nitro copper (II) phthalocyaninehas been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalystsovernanodimensionalzeolites. 4-Nitro phthalonitrile synthesized from phthalimide in three steps. The newly prepared compounds have been characterized by IR, UV-Vis, 1</sup...

Manganese (Mn) oxides are among the most reactive sorbents and oxidants within the environment, where they play a central role in the cycling of nutrients, metals, and carbon. Recent discoveries have identified superoxide ([Formula: see text]) both of biogenic and abiogenic origin as an effective oxidant of Mn(II) leading to the formation of Mn oxides. Here we examined the conditions under whic...

our main objective is a better understanding of spin spin interaction of dinuclear copper(ii) complexes through  system. the synthesis and characterization of two new dinuclear copper(ii) complexes, based on the use of large, pyrole-containing macrocycles, the so called “ expanded porphyrins” , [cu2(macrocycle)]4+ is described. a chloroform solution spectrum of two complexes taken at room tem...

Objective(s): A remarkable growing effort has been conducted by several researchers to fabricate food packaging materials which are able to protect foodstuffs and enhance their shelf-life from food-borne pathogens and fungal attack which causes great damage to the food industries. Recent studies has focused on the potential applications of nano-metal oxides in food packaging area. Method...

In vivo, copper(II) is a major source of reactive oxygen species (ROS) via Fenton Haber Weiss reactions. Interest in Alzheimer’s disease has led to intensive studies into the generation of ROS catalyzed by copper(II) with or without the presence of β-amyloid (Aβ) peptides and biological antioxidants. We establish a potential connection between tyrosine nitration and copper(II) toxicity in neuro...

Copper(II) complexes of several hydroxyflavones were prepared and characterised through their physico-chemical properties. The nuclease activity of three synthesised complexes is reported. These copper(II) complexes present more nuclease activity than the ligands and the copper(II) ion.

The oxidation reactions of BaLaCuS3 in the artificial air atmosphere were studied at different heating rates temperature range 50–1200 °C. stages determined by DSC-TG, XRD and IR–vis methods. kinetic characteristics proceeding obtained with use Kissinger model a linearized form. Compound was stable up to 280 Upon further 1200 °C, this complex sulfide underwent three main stages. first stage is ...

ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. these compounds have been used as ligands for complexation of transition metals, such as copper(ii) and nickel(ii). according to the spectrosocopic data, copper(ii) cation forms (i: 1) and (i:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (i &apos;-isoquinoly1)- 1,1,3,3-te...
