The management of Lyctus africanus, one the major dry wood pests in tropical region is difficult due to its secluded habits and long lifecycle therefore, control measures are limited usage insecticides. insecticides particularly metal salts effective, but some cases their leaching leads concerns about environmental pollution. Nanometal particles found be more effective than salts. Presently ava...
The new electrical conductive material, copper alloy, C194 in situ composite, has been developed for the application to leadframe, high field magnet and trolley wire. This material has a low cost, high thermal and electrical conductivity, easy fabrication and joining, and also has a wide range of attainable mechanical properties. In C194, copper is one of the core materials in producing leadfra...
An approach to producing films of nanometer-sized copper oxide particulates, based on polyelectrolyte-mediated assembly of the precursor, copper(II)phthalocyanine tetrasulfonate (CPTS), is described. Multilayered CPTS and polydiallyldimethylammonium chloride (PDADMAC) were alternately assembled on different planar substrates via the layer-by-layer (LbL) procedure. The growth of CPTS multilayers...
Abstract Nanotechnology is a completely unique branch of technology that offers with substances in very small size between (1–100 nm) various crystal shapes. Metals have ability to produce large number oxides. These metal oxides play major role many areas chemistry, physics, material science and food science. In this research, Zinc Oxide (ZnO) Copper (II) oxide nanoparticles were synthesized vi...
هدف از انجام این پروژه بررسی امکان حل سازی سنگ معدن کم عیار سولفیدی سونگون با استفاده از باکتری است. بدین منظور، ابتدا آنالیز خاک کم عیار سولفیدی معدن به روش شیمیایی و مینرالوژیکی صورت گرفته شد، همچنین آنالیزهای سرندی نیز مورد بررسی قرار گرفته است. سپس امکان سنجی لیچینگ شیمیایی کانسنگ کم عیار توسط آزمایشات بطریهای غلطان مورد بررسی قرار گرفته است. در ادامه به تعیین قابلیتهای میکروارگانیسمهای جدا...
Innate immune cells play a key role in the pathogenesis of multiple sclerosis and experimental autoimmune encephalomyelitis (EAE). Current clinical imaging is restricted to visualizing secondary effects of inflammation, such as gliosis and blood-brain barrier disruption. Advanced molecular imaging, such as iron oxide nanoparticle imaging, can allow direct imaging of cellular and molecular activ...
1. Copper compounds (calcium copper edetate, copper heptanoate, copper methionate, copper chloride, copper oxide, dicopper oxide and copper gluconate) are normally used, orally in feed or in an injectable solution, to treat copper deficiency in food-producing animals. In veterinary medicine, the recommended doses are 50 to 100 mg copper per animal given as a single injection. Copper has antimic...
Nanostructured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4 as wet ...
Microwave Plasma Enhanced Chemical Vapor Deposition (MPECVD) is an innovative technique allowing the direct preparation, at low temperature, of different valence states of copper (Cu°, Cu, Cu). The precursor used is a volatile metalorganic one (copper acetylacetonate) with helium as a carrier gas. The precursor is then transported in a remote plasma of Ar, A1/O2 or A r / ^ O gas at low pressure...
