copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

OBJECTIVE We examined the pulmonary toxicity of nickel oxide nanoparticle agglomerates in the rat lung following an intratracheal instillation. METHODS The weighted average surface primary diameter of nickel oxide nanoparticles was 8.41 nm, and the count median diameter of nickel oxide nanoparticle agglomerates suspended in saline was 1.34 µm. Male Wistar rats were exposed to 1 mg (3.3 mg/kg)...

Fire disaster is the major factor to endanger the public and environmental safety. People lost their life during fire disaster mainly be attributed to the dense smoke and toxic gas under combustion, which hinder the escape of people and the rescue of firefighters under fire disaster. The smoke suppression effect of several transitional metals oxide on the epoxy resin treated with intumescent fl...

The characteristics of copper oxide removal are comparably investigated under different pulsing strategies. A two-dimensional model is utilized to numerically simulate the laser ablative cleaning process. In the model, property discontinuity and Stephan and kinetic boundary conditions are taken into account, and the moving phase interface in the material is evaluated with the enthalpy method. E...

We report a two-step electrochemical process to grow copper oxide nanowires without the use of templates and surfactants. The first step is to electrochemically corrode amorphous Cu–W oxides presputtered on fluorine-doped tin oxide (FTO) coated glass substrates under positive potentials. The second step is to use the corroded samples to grow copper oxide nanowires electrochemically under negati...

In this study, molybdenum-copper/alumina nano composite was synthesized with mechano-chemical method using high energy planetary ball milling. The molybdenum oxide, copper oxide and aluminum powder were used as starting materials and reaction appeared to occur through a rapid combustion reaction process. The evaluation of powder particles after different milling times was studied by X-ray diffr...

Although silver nanowire meshes have already demonstrated sheet resistance and optical transmittance comparable to those of sputter-deposited indium tin oxide thin films, other critical issues including surface morphology, mechanical adhesion and flexibility have to be addressed before widely employing silver nanowire networks as transparent conductors in optoelectronic devices. Here, we demons...

incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

Our long-term goal is to develop a hybrid cellulose-copper nanoparticle material as a functional nanofiller to be incorporated in thermoplastic resins for efficiently improving their antimicrobial properties. In this study, copper nanoparticles were first synthesized through chemical reduction of cupric ions on TEMPO nanofibrillated cellulose (TNFC) template using borohydride as a copper reduci...
