A three-dimensional finite element model for phase change random access memory (PCRAM) is established for comprehensive electrical and thermal analysis during SET operation. The SET behaviours of the heater addition structure (HS) and the ring-type contact in bottom electrode (RIB) structure are compared with each oth…
In 1948, De Beers launched an advertising campaign headed by the slogan ”Adiamond is forever,” convincing the American public that diamonds are synonymous with romance, glamour, and prestige. Since then, diamonds have been desirable as symbols of social and economic success. The expensive price tag, associated with to…
The rapid dendritic growth of primary Ni 3 Sn phase in undercooled Ni-30.9%Sn-5%Ge alloy is investigated by using the glass fluxing technique. The dendritic growth velocity of Ni 3 Sn compound is measured as a function of undercooling, and a velocity of 2.47 m/s is achieved at the maximum undercooling of 251 K (0.17T…
The high-temperature Raman spectroscopy technique is applied to investigate the phase transition of LiB 3 O 5 crystal. The result shows that the crystal is stable in the range of 293–893 K. When the temperature increases up to above 1107K, the phase transition occurs. In the liquid phase, Li 2 B 4 O 7 crystal precipit…
Fe-doped In2O3 films are grown epitaxially on YSZ (100) substrates by pulsed laser deposition. The in-situ reflection high-energy electron diffraction, the atomic force microscopy, and the x-ray diffraction patterns show that the films have a well defined cubic structure epitaxially oriented in the (100) direction. Ro…
Abstract ChemInform is a weekly Abstracting Service, delivering concise information at a glance that was extracted from about 200 leading journals. To access a ChemInform Abstract of an article which was published elsewhere, please select a “Full Text” option. The original article is trackable via the “References” opt…
Glow discharges of oxygen and nitrogen were applied to low density polyethylene thin films in order to study accelerated oxidation and nitridation in the polymer. The studies were focused on the morphologic, crystalline and hydrophilic evolution promoted by plasma exposure. The particular chemical characteristics of t…
Carbon nanotube (CNT) emitters were formed on line-patterned cathodes in microtrenches through a thermal CVD process. Single-walled carbon nanotubes (SWCNTs) self-organized along the trench lines with a submicron inter-CNT spacing. Excellent field emission (FE) properties were obtained: current densities at the anode…
Magnetic composites of carbon nanotubes (CNTs) are synthesized by the in situ catalytic decomposition of benzene at temperatures as low as 400°C over Fe nanoparticles (mean grain size = 26 nm) produced by sol-gel fabrication and hydrogen reduction. The yield of CNT composite is up to about 3025% in a run of 6 h. FESEM…
Dielectric tunable composite ceramics Ba 0.6 Sr 0.4 TiO 3 -Mg 2 TiO 4 (BST-MT) are prepared with a heterogeneous nucleation sol-gel approach. The Mg 2 TiO 4 powders are synthesized by the conventional solid-state reaction method. The micro-sized MT powders with dispersant Ciba-4010 are introduced into Ba-Sr-Ti sol to…
We propose a new method for preparing polymeric nanocomposites and porous materials using self-assembled templates formed by 1,3:2,4-dibenzylidene sorbitol (DBS) organogels. DBS is capable of self-assembling into a 3D nanofibrillar network at relatively low concentrations in some organic solvents to produce organogels…
We prepare the gallium oxide (β-Ga 2 O 3 ) nanomaterials from gallium and oxygen by thermal evaporation in the argon atmosphere and research their oxygen sensing under UV illumination with different oxygen pressures. X-ray diffraction reveals that the synthesized product is monoclinic gallium oxide, it is further conf…
Nanocrystalline zirconia powders have been prepared by microwave-hydrothermal synthesis starting from aqueous solution of ZrOCl2·8H2O. Results of investigations on the aqueous suspension stability of the washed zirconia nanopowders by dynamic light scattering showed that the suspension, constituted by superaggregates…
We studied the anchoring of 6CB on a series of self-assembled monolayers (SAMs) with a functional group that mimics that of the nematic liquid crystal (LC). The SAMs were first characterized by wetting, Fourier-transform infrared spectroscopy, and surface potential measurements. We found that, in two of these SAMs, th…
We report for the first time the deposition of fluorocarbon thin films on outer and inner surfaces of millimetric sized diameter stainless steel mini-tubes by radiofrequency pulsed plasma polymerization for coronary stent applications. The deposition was performed under a glow discharge with a mixture of hexafluorethy…
ABSTRACT Wheat starch‐based films were formulated by dispersing 4 g starch in distilled water, and plasticized with Gly and PEG in different levels (Gly = 2 and 3 mL/100 mL and PEG = 0.0, 0.2, 0.3 and 0.4 mL/100 mL). The emulsion films were evaluated for mechanical properties, water vapor transmission rate (WVTR). Pis…
The active rigidity joint is a composite mechanism using shape memory alloy and shape memory polymer to create a passively rigid joint with thermally activated deflection. A new model for the active rigidity joint relaxes constraints of earlier methods and allows for more accurate deflection predictions compared to fi…
The effect of rigid polymer content, tetrafluoroethylene (TFE), within elastomer polymer on the coalescence behavior of suspended rubbery particles during fast, diffusion-limited cluster−cluster aggregation (DLCA) has been studied in this work. This is achieved by first measuring in situ the time evolution of the aver…
Abstract A nickel and yttrium‐stabilized zirconia (Ni‐YSZ) composite is one of the most commonly used anode materials in solid oxide fuel cells (SOFCs). One of the drawbacks of the Ni‐YSZ anode is its susceptibility to deactivation due to the formation of carbonaceous species when hydrocarbons are used as fuel supplie…
