The anatase-rutile phase transformation in Ar–Cl2 atmosphere has been investigated by X-ray powder diffraction, thermogravimetry, and scanning electron microscopy. At 950°C the phase transformation in Ar–Cl2 atmosphere is about 300 times faster than in air. The growth of crystals of rutile from the vapor phase has been observed. We also determined that anatase powders with adsorbed chlorine rapidly rapidly transformed to rutile and underwent a color change from white to gray when they were heated in Ar atmosphere. 相似文献

Benefiting from an understanding of economic and political markets includes recognition that engineers themselves can change these environments. Understanding healthcare and other technology markets includes an understanding that the markets sometimes don't just exist-they are altered and sometimes created by the technology. A less expensive and more effective means to monitor a disease such as PKU enhances the likelihood that insurers will cover costs of such monitoring. Recognizing the complexity of economics and policy recognizes that understanding sometimes comes in a burst of insight but more usually, and surely, builds in steps. Since improvements in quality of life are inadequately captured by the market, will political "markets" develop subsidies or regulations to encourage technology?. 相似文献

The effects of recipe compositions in terms of leavening agent (ammonium and sodium bicarbonates) and sugars (sucrose and
glucose), and baking conditions (temperature and time) on HMF formation in cookies were studied. Five recipes were prepared
by varying the types of leavening agent and sugar. The cookies were baked at different temperatures (180, 200, 210 and 220
°C) for different time (10, 15, 20 and 25 min) to monitor physical and chemical changes in cookie composition in terms of
water activity, pH, surface browning, sugar decomposition, and hydroxymethylfurfural (HMF) formation. Decreasing moisture
to a level under a water activity of 0.4 appeared as the critical point in baking where the rate of HMF formation drastically
increased after this point. After this stage, sucrose decomposed very rapidly if ammonium bicarbonate was used as the leavening
agent at temperatures greater than 200 °C. Replacing ammonium bicarbonate with sodium bicarbonate maintained pH of cookies
ranging between 9.0 and 10.0 during baking, which limited the decomposition of sucrose. 相似文献

Irradiation combined with a conventional cooking procedure was applied to meatball and the effects on bacterial load and inoculatedAeromonas hydrophila were determined. Meatball samples were irradiated by using a60Co source at the dose levels of 0, 0.30,0.75,1.50,2.50 kGy and cold stored at 4±1°C for 7 days. Bacterial load and the count ofA. hydrophila decreased when the irradiation dose level increased. A minimum inhibition effect was found at the dose of 0.30 kGy. Irradiation in combination with a conventional cooking procedure was found to be more effective in reducingA. hydrophila and the bacterial load in meatball. This study indicated that a dose of 0.75 kGy was sufficient to destroy approximately 104 cfu/g ofA. hydrophila in meatball. 相似文献

A real-time knowledge processing procedure is proposed for rule-based systems in general and control systems applications in particular. Distinguishing features of the procedure include a mechanism for rule base compression and an inference scheme based on matrix operators. The procedure is also amenable for schedulability analysis to provide response time warranty. An application concerning supervisory group control of elevators is also included to show the usefulness of the proposed procedure 相似文献

Evaporation of fluid at micro and nanometer scale may be used to self-assemble nanometre-sized particles in suspension. Evaporating
process can be used to gently control flow in micro and nanofluidics, thus providing a potential mean to design a fine pattern
onto a surface or to functionalize a nanoprobe tip. In this paper, we present an original experimental approach to explore
this open and rather virgin domain. We use an oscillating tip at an air liquid interface with a controlled dipping depth of
the tip within the range of the micrometer. Also, very small dipping depths of a few ten nanometers were achieved with multi
walls carbon nanotubes glued at the tip apex. The liquid is an aqueous solution of functionalized nanoparticles diluted in
water. Evaporation of water is the driving force determining the arrangement of nanoparticles on the tip. The results show
various nanoparticles deposition patterns, from which the deposits can be classified in two categories. The type of deposit
is shown to be strongly dependent on whether or not the triple line is pinned and of the peptide coating of the gold nanoparticle.
In order to assess the classification, companion dynamical studies of nanomeniscus and related dissipation processes involved
with thinning effects are presented. 相似文献

It has been one of the most important issues to minimize the stress reduction during phase change in GST (Ge2Sb2Te5) alloy for PRAM (Phase-change Random Access Memory) applications, because the alloy has been reported to face the significant
stress during the phase change. We fabricated GST/oxide/substrate as a basic structure, and then added two more structures
by capping an adhesion layer (Ti) or a barrier metal (TiN) on GST layer, respectively. We report that TiN-capped structure
shows about 40% stress reduction during the phase change compared with that of the basic structure. The stress reduction is
considered to be due to the intrinsic compressive stress in TiN film itself. 相似文献

This article describes the solution combustion synthesis technique as applicable to iron oxide powder production using urea
as fuel and ferric nitrate as an oxidizer. It focuses on the thermodynamic modeling of the combustion reaction under different
fuel-to-oxidant ratios. X-ray diffraction showed magnetite (Fe3O4) and hematite (α-Fe2O3) phase formations for the as-synthesized powders. The smallest crystallite size was obtained by stoichiometric chemical reaction.
The magnetic properties of the samples are also carefully discussed as superparamagnetic behavior. 相似文献

A polyurethane (MDI‐DR19Cl) bearing azobenzene moieties was prepared by condensation of 4,4′‐diphenylmethylenediisocyanate and an azobenzene compound, 2‐chloro‐4‐nitro‐4′‐[bis‐(2‐hydroxyethyl)]amine‐azobenzene (DR19Cl). Blends of MDI‐DR19Cl and a poly(amide‐imide) were prepared and characterized by UV‐visible and Fourier transform infrared spectroscopy and by DSC. The purpose of using the blends was to overcome the lack of stability of cast films of pure MDI‐DR19Cl, which tend to crack on storage under ambient conditions. This was successfully achieved and, depending on blend proportions, flexible self‐standing films could be prepared after thermal treatment. Optical storage experiments performed with the blends and pure MDI‐DR19Cl cast films showed a decrease in the remnant values of photoinduced birefringence in the blends (60 % for the blend with 5 wt% MDI‐DR19Cl) compared to pure MDI‐DR19Cl (75%), but, taking into account the low content of MDI‐DR19Cl used, the results obtained are probably sufficient to show the viability of these blends in optical storage applications.
