We report a method for controlling the orientations of conjugated polymers in the active layer of organic thin-film transistors (OTFTs) by annealing the film at the melting temperature in a vertically aligned multiwalled carbon nanotube (VA-CNT) template under various load pressures. Poly(3-hexylthiophene) [P3HT] molecules are effectively aligned in the melting state annealing at 240 °C for 30 ...

PURPOSE The purpose of this study was to test the association between tear film fluorescence changes during tear break-up (TBU) or thinning and the concurrent ocular sensory response. METHODS Sixteen subjects kept one eye open as long as possible (MBI), indicated their discomfort level continuously, and rated ocular sensations of irritation, stinging, burning, pricking, and cooling using visu...

A series of high resolution simulations on film cooling with varying blowing ratios and inclination angles are carried out by using in-house code based hybrid thermal lattice Boltzmann method. Three ranging from 0.2-0.8 four 15? to 60? chosen for the simulations. The evolutionary mechanism coherent structure in three domains film-covering region is studied view space time. Besides, influencing ...

(111)-oriented and random oriented Pb0.8Ba0.2ZrO3 (PBZ) perovskite relaxor ferroelectric thin films were fabricated on Pt(111)/TiOx/SiO2/Si substrate by sol-gel method. Nano-scaled antiferroelectric and ferroelectric two-phase coexisted in both (111)-oriented and random oriented PBZ thin film. High dielectric tunability (i = 75%, E = 560 kV/ cm ) and figure-of-merit (FOM ~ 236) at room temperat...

We consider solutions where the surface tension of the solvent γs is smaller than the surface tension of the polymer γp. In an evaporating film, a plume of solvent rich fluid, then induces a local depression in surface tension, and the surface forces tend to strengthen the plume. We give an estimate (at the level of scaling laws) for the minimum thickness e ∗ required to obtain this instability...

In high-resolution radioautography, a common source of difficulty in the use of the loop method for applying Ilford L-4 emulsion (1) is an inhomogeneous distribution of water in the emulsion . This inhomogeneity may be due to bad environmental conditions during transportation. It is easily cured by melting the entire bottle of emulsion once before use. Our standard procedure for the preparation...
