Influence of defects induced by chemical treatment on the electrical and thermal conductivity nanofluids containing MWCNT–COOH was investigated presented.
In this study, the successful hydroxyl functionalization of carbon nanotubes (MWCNT-OH) was prepared by chemical treatments and characterized Raman FTIR spectra. MWCNT-OH successfully dispersed into ethylene glycol (EG) with Tween-80 surfactant an ultrasonication method to prepare nanofluids. Thermal conductivity nanofluid investigated, a maximum thermal enhancement about 24% at 50°C obtained containing 0.64 vol.% MWCNT concentration. The photothermal conversion performance also investigated...
LaMnO 3 (LMO) nanopowder was synthesized by the microwave combustion method using glycine and nitrate salts of La Mn as precursors. The as-prepared LMO powder pressed at high pressure annealed 1000°C for 8 hours to make a target thin film deposition. structural elemental analysis obtained X-ray diffraction (XRD) energy dispersive spectroscopy (EDS). Thin films were fabricated pulsed electron deposition (PED) room temperature. effects discharge voltage oxygen/argon flux ratio on produced...
Zinc oxide (ZnO) is a well-known semiconductor with valuable characteristics: wide direct band gap of ˜3.3 eV, large exciton binding energy 60 meV at room temperature, high efficient photocatalyst, etc. which have been applied in many fields such as optical devices (LEDs, laser), solar cells and sensors. Besides, various low dimensional structures ZnO terms nanoparticles, nanorods, nanoneedles, nanotetrapods find applications technology life. This material also appealing due to the diversity...
Abstract In this work, the anharmonic Einstein model is developed to determine Debye temperature and investigate effects on extended x-ray absorption fine structure (EXAFS) cumulants of hexagonal close-packed (hcp) metals. We have derived analytical expressions effective potential, force constant, first four EXAFS as a function axial ratio e = c / . Numerical calculations been conducted for hcp Zn, Zr, α -Ti, Ru Hf metals up 800 K. Our findings indicate that anharmonicity thermal lattice...
Abstract Zero-point vibrations of solid hydrogen are investigated by analyzing the molecular mean-squared displacement (MSD) and relative functions within statistical moment method approach in mechanics. Numerical computations these thermodynamic properties were conducted for from 0 K to its phase transition temperature using Wigner-Kirkwood mean-field potential derived Buckingham exp-6 potential. We have shown that quantum-mechanical zero-point play an important role at low temperature. And...
