This paper considers the flow and heat transfer in a non-Newtonian power-law liquid film over a horizontal unsteady stretching sheet. The fluid viscosity and thermal conductivity are assumed to vary with temperature, whereas the Prandtl number is assumed to be constant. The transformed time dependent conservation laws are solved numerically. The velocity, temperature and thickness of the film, ...

antioxidant active packaging is one of the active packaging that prevents of lipid oxidation by releasing antioxidant during storage of food. in recent years the use of natural antioxidant instead of the synthetic variety in these packaging has been considered. the aim of this study was evaluating the performance of polymeric film coated with natural antioxidant (rosemary extract) to prevent li...

The magnetization of a thin Fe-Co cyanide film has been investigated from 5 K to 300 K and in fields up to 500 G. Upon illumination with visible light, the magnetization of the film rapidly increases. The original cluster glass behavior is further developed in the photoinduced state and shows substantial changes in critical temperature and freezing temperature. © 2001 Elsevier Science.

Equilibrium conductivity fluctuations of mesoscopic domains are found in film and bulk single-crystal manganite colossal magnetoresistive material. Temperature and field dependences of the Boltzmann factors for a collection of two-state fluctuators give measures of the magnetic moment and entropy differences between the states, and of the fluctuator volumes. The large resistance step size impli...

Gallium doped zinc oxide, GZO, thin films have been deposited onto glass substrate by rf magnetron sputtering at various substrate temperatures. The electrical and optical properties of the thin films have been studied as a function of substrate temperature. X-ray diffraction was used in order to investigate thin film structures. The thin film structure was stabilised by heating the samples in ...

In this work, we present experimental studies on the cross-plane thermal conductivity of InAs/AlSb superlattices. The thermal conductivities of MBE grown InAs/AlSb superlattices are measured using the 3ω method from 80-300 K. The influence of the growth temperature and post annealing is investigated. Significant reductions in thermal conductivity are observed in these superlattices compared to ...

Nano-structured TiO(2) thin film has been successfully fabricated at room temperature. Using a quarter wavelength characterization method, we have measured the acoustic impedance of this porous film, which can be adjusted from 5.3 to 7.19 Mrayl by curing it at different temperatures. The uniform microstructure and easy fabrication at room temperature make this material an excellent candidate fo...

The transformation behaviors on metamagnetic shape memory Ni46.4Mn38.8In12.8Co2.0 film were investigated by X-ray diffraction experiments in the temperature up to 473 K and magnetic fields μ0H up to 5 T. The prepared film showed the parent phase with L21 structure at 473 K, and with preferred orientation along the 111 plane. The magnetic field induced reverse transformation was directly observe...

Inside a modern flat-panel display, the TFT array acts as the analog memory that stores the image information. To ensure high overall yield, it is crucial to thoroughly test the TFT array before it enters the assembly line. However, TFT array testing gets complicated in systemon-panel displays because the peripheral circuits integrated on the same substrate as the array limit the access to the ...
