In the electronic industry, there is a need for materials of different electrical conductivities ranging from the semi-conducting to the conducting region. In addition the materials should be easily processable and stable . The synthesis of new electrically conducting polymers with different chemical structures provides an efficient method for the introduction of new materials with the qualifications described above. Furthermore, knowledge of the electrical behavior of a great member of polymers with various chemical structures enables us to understand the relationship between the electrical...

The aim of this work is to prepare a series of mixed ligand complexes of Pd(II) and Cu(II) based on the cyclic dithiarine derivatives using different nitrogen , phosphorous and arsine containing ligands, and to study structure and bonding aspects of these new different complexes , using the suitable techniques.The chosen metal ions and the ligands are both scientific and pharmaceutical importance. The work is to be accomplished through the following steps: 1.Preparation of dithiarine ligand starting from dithiooxamide. 2.Preparation of Pd(DMSO)2Cl2 as astarting material. 3.Preparation of...

Plant oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a correspondingly high importance right at the start of product development. To ensure a high degree of product safety for consumers and the environment, renewable resources have often been shown to have advantages...

Poly(vinyl chloride) is second only to polyethylene among five kinds of general plastic materials, which was widely used in the industries including architecture, electronic, chemical engineering, packaging, transportation, etc.However, low photostability of PVC leads to hydrogen chloride loss,discoloration, and finally serious corrosion phenomena,accompanied by changes of physical and chemical properties of PVC. The low cost and the good performance of poly(vinyl chloride) products have increased the utilizationof this polymer in building, mainly in exterior application, such as window...

Poly(vinyl chloride), better known by its abbreviation PVC, is one of the most versatile plastics. It is the second largest manufactured resin by volume worldwide; currently, its production per annum exceeds 31 million tons. research and industrial applications, with respect to polymerization, stabilization, bulk property modification, and chemical and material recycling of PVC waste. The low cost and the good performance of poly(vinyl chloride) products have increased the utilization of this polymer in building, mainly in exterior application, such as window profiles, cladding structure and...

A new ligand of dithiocarbamato derivative containing triazole ring and hydrazide group in it, have been synthesized in this work. The product was isolated, characterized, and studied by appropriate physical measurements i.e. FT-IR, UV-Vis spectroscopy and the elemental analysis C.H.N.S as well as melting point. The new ligand was used to prepare a number of transition metal complexes (heavy and light metals). Cytotoxicity effect of some complexes (heavy metals) (PtL, AuL, RhL, CuL & PdL) as well as ligand have evaluated against RD cell line by using four different concentrations (500, 250,...
