Due to rapidly increasing power densities in nanoelectronics, efficient heat removal has become one of the most critical issues in thermal management and nanocircuit design. In this study, we report a surface nanoengineering design that can reduce the interfacial thermal resistance between graphene and copper substrate by 17%. Contrary to the conventional view that a rough surface tends to give...

A two-step protocol (nano-filtration and reverse osmosis) was applied for natural organic matter (NOM) preconcentration of a seawater sample. Complexing affinities of the so concentrated marine dissolved NOM (DNOM) towards major and trace cations were studied by potentiometric and voltammetric titration techniques. The potentiometric titration experiments fitted by models describing and charact...

Cu2O nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of Schiff base copper (II) complex (1) as precursor. Liquid paraffin was used as solvent and reductant. Span 80 was applied to control the morphology of cuprous oxide nanoparticles. The nano structure of the complex was characterized by X-ray diffraction measurement...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

This contribution reports an ecological benevolent route for the fabrication of copper oxide nanoparticles (CuONPs) using Leucaena leucocephala L. leaves extracts at room temperature. Phytochemical screening of the fresh aqueous leaves extract showed the presence of tannins, saponins, coumarins, flavonoids, cardial glycosides, steroids, phenols, carbohydrates and amino acids. Copper oxide parti...

The reusable and easily separable nano-copper ferrite has been used to study its excellent catalytic behavior for thermolysis of modified nitrotriazolone (NTO), an insensitive energetic material act as oxidizer chemical propulsion systems.

In This applicable research, investigating absorption of process ofErythrosine dye on Copper oxide Nano particles Adsorbent was studied. First, prepared dyeconcentrations of 6, 8 and 12 mg L-1 and then effects of parameters such as concentrations ofinitial dye, time and pH on dye absorption efficiency were investigated.The dyeconcentrations in different samples were measured via spectrophotomet...

Copper nano/microparticles were synthesized in octadecene at 290 °C by thermal decomposition method. acetate monohydrate, stearic acid, and 1-octadecanol used as copper precursor, capping mild reducing agents, respectively, the synthesis. Borosilicate glass substrates submerged into reaction solution during synthesis coated nano/ microparticles. Thermal coating techniques combined this study. t...

In the present study, the hardness and electrical properties of copper based composite prepared by hot pressing of mechanically alloyed powders were predicted using Artificial Neural Network (ANN) approach. Milling time (t, h), particles size of mechanically alloyed powders (d, nm), dislocation density (ρ, m) and compressive yield stress (σ0.2, MPa) were used as inputs. The ANN model was develo...
