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 ...

When the Gibbs-Thomson-Herring anisotropic capillary boundary condition is applied at the solidliquid interface of a crystallite with shape anisotropy, such as a needle crystal or dendrite, the interface can develop periodic non-monotone temperature distributions. This surprising result was discovered recently for the case of a slender ellipsoidal crystallite with its solid-melt interfacial ene...

Olivine-basalt aggregates sintered at high P/T have been used as a simplest approximation of partially molten upper mantle peridotite. In the past, geometry of partial melt in polycrystalline olivine (and other materials) has been characterised by dihedral (wetting) angles which depend upon surface free energy. However, since olivine (like most other crystalline materials) is distinctively anis...

Heat emanates from gold nanorods (GNRs) under ultrafast optical excitation of the localized surface plasmon resonance. The steady state nanoscale temperature distribution formed within a polymer matrix embedded with GNRs undergoing pulsed femtosecond photothermal heating is determined experimentally using two independent ensemble optical techniques. Physical rotation of the nanorods reveals the...

Aluminum anodes have been widely used in the cathodic protection of marine structures. However there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. Addition of alloying elements such as Zn and In not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra ...

<0.02°C temperature increments on a system with <0.02°C uniformity variability (Tesoriero 2008). However, successful discrimination of sequence variants, including the most difficult-to-detect class IV SNPs, is not solely dependent on the temperature increments from which melt data are collected. Several factors influence DNA melting behavior, including reaction mix composition, amplicon size, ...

in order to fabrication of transparent glass-ceramics with li-mica nano crystals, the glasses with chemical composition of 94.9 mass% li(1+x)mg3alsi3(1+x)f2 (x=0.5) with 5.1 mass% mgf2 were crystallized. the glasses were fabricated via the conventional melt-quenching technique. mica crystals were precipitated in the glass phase by later heat treatment. glass samples had glass transition tempera...

Single crystals of (Cd,Zn)Te are an excellent substrate material for epitaxial growth of (Hg,Cd)Te layers and are usually grown by the vertical Bridgman method. We present a simulation of the whole growth process in two steps: In the rst step, the (stationary) heat transport in the furnace is modeled and calculated for diierent positions of the ampoule. This gives information about the most imp...

Understanding the coercivity mechanism has had a substantial impact on developing economically more attractive RE-based (RE = rare earth) permanent materials because of price volatility of key RE metals (i.e., Nd and Dy) in recent years. In this work, we investigated the microstructure and magnetic properties of melt-spun (Nd0.8Ce0.2)2.4Fe12Co₂B ribbons and annealed samples at 773 K for 15 min ...

In order to obtain a lightweight material having an excellent high-temperature strength, Mg alloy composites reinforced with short alumina fibers and in situ Mg2Si particles were fabricated. The composites were fabricated by pressureless infiltration of the Mg alloy melt into the preform consisting of the fibers and attached Si particles. The volume fraction of Si particles in the preform, the ...
