Diesel particulate filters (DPF) have seen widespread use in on- and off-road applications as an effective means for meeting increasingly stringent particle emissions regulations. Over time, incombustible material or ash, primarily derived from metallic additives in the engine lubricant, accumulates in the DPF. Ash ac…
磨擦上的硅粒子内容和严峻的温度的效果并且穿在原处扔硅粒子的性质增强的 ZA27 composites 被调查。wear 机制被穿的表面和他们的方面看法的观察主要讨论。结果显示变化与硅粒子内容增加穿抵抗，根本，测试，温度适用，与非单调的变化的一种方式显示出一个类似的趋势。，当内容什么时候是不到 2 vol.% 或超过 5 vol.% ，增加了时是 surpdsed wear 抵抗从 2 vol.% 随硅粒子内容的增加减少了到 5 vol.% 。同样，磨擦系数也没单调地变化。支配穿从粘附伴随的塑料变丑的相对严重的政体改变的机制穿到油迹的温和政体，然后，到严重塑料的很严重的政体，变丑导致了穿，并且当硅内容增加了，再最后穿到磨料伴随的油迹…
The influence of a transverse electric field on the specific heat of triglycine sulfate (TGS) has been studied. The specific heat of TGS has been measured on heating the sample from the ferroelectric to the paraelectric phase after prolonged application of transverse electric field (i.e. perpendicular to the ferroelec…
The crystal structure of the ternary compound Tb 0.67 PtAl 5 (structure type Sc 0.6 Fe 2 Si 4.9 , hP20-4.67, P6 3 /mmc, a = 4.2734(10), c = 16.391(3) ) was refined from X-ray single-crystal diffraction data. It contains two kinds of slab stacked along [0 0 1]: slightly puckered layers of composition PtAl 2 and flat la…
We introduce a method for determining the functional form of the stochastic and dissipative interactions in a dissipative particle dynamics (DPD) model from projected phase space trajectories. The DPD model is viewed as a coarse graining of a detailed dynamics that displays a clear timescale separation. Based on the M…
We study the adsorption of ideal random lattice copolymers with correlations in the sequences on homogeneous substrates with two different methods: An analytical solution of the problem based on the constrained annealed approximation introduced by Morita in 1964 and the generating function technique, and direct numeri…
Influence of retained austenite on rolling-sliding wear resistance of austempered silicon alloyed steel
Concerns exist about possible exposures of researchers and laboratory personnel to CNTs, fibers (respirable and nanoscale) and nanoparticles during handling, synthesis, processing, post-processing, and machining of nanomaterials and composites containing CNTs. Prior exposure work is reviewed and new monitoring results…
A newly constructed electrochemical multisensor containing 8 different sensors (5 different solid amalgam electrodes, platinum, gold and glassy carbon electrodes) for analysis of small sample volumes (5–200 µL) was developed. The multisensor was connected to the specially constructed and developed electrochemical mult…
Significant improvements in surface wettability and boiling heat transfer on oxide film coatedmaterials by radiation induced surface activation (RISA) phenomenon were confirmed in our previous study. To delineate the RISA effect in actual boiling systems or in a high-temperature and high-pressure environment, this stu…
Elintarvikkeen hintamarginaalilla tarkoitetaan elintarviketeollisuuden, kaupan ja muiden väliportaiden osuutta elintarviketuotteen kuluttajahinnasta. Hintamarginaalit ovat kasvaneet pitkällä aikavälillä niin Suomessa kuin muissa teollistuneissa maissa. Kehityksen taustalla on useita syitä, mm. elintarvikehygienian tiu…
Usage of highly reactive coke in order to decrease thermal reserve zone temperature in blast furnace is considered promising to increase reaction efficiency in blast furnace and to decrease reducing agent rate. We focused attention on the catalytic effect of iron and succeeded in producing highly reactive formed iron…
In this study structural characteristics of several carbon based nanostructures on the hydrogen abundance in the material are investigated with the quantized liquid density functional theory - QLDFT. We applied this theory to evaluate the hydrogen storage capacities of nanoporous materials: Compact storage of hydrogen…
A major barrier to rigorous failure predictions for polymer-matrix composites is the lack of measurements to quantify structural model parameters including matrix-dominated stress-strain relations and failure criteria. Accurate interlaminar constitutive properties are especially important for structural analysis of th…
In this work,we review the current technological challenges for large-size AMOLED displays with an emphasis on the backplane technology. Then,it will be discussed how the new technology of oxide TFTs combines the advantages of LTPS and a-Si TFTs to make an optimal solution for large-size backplanes. In particular,we r…
where σo is a constant and W – activation energy [1-10]. If the logarithm of the conductivity σ is plotted on the ordinate against the reciprocal of the temperature T on the abscissa, a straight line is obtained whose slope one may calculate the activation energy, W. The extrapolated intercept of this line on the ordi…
Dense and high oxide ion conducting solid electrolytes, Al-doped lanthanum silicate [La9.33+x(Si6−yAly)O26+1.5x−0.5y] were fabricated and their electrical conducting properties were studied. Among the specimens tested, the electrical conductivity of the slight Al-doped one (x=0.67, y=0.2) was the highest though that w…
In this study, we describe a novel molecular self-assembling system of a nucleobase-functionalized oligopeptide. An adenine-terminated amphiphilic triblock peptide (1), which consists of hydrophobic Leu and hydrophilic Lys, was newly synthesized as a building block for self-assembly. The conformational and self-assemb…
Multi-walled carbon nanotubes (MWCNTs) were functionalized by radiation-induced graft polymerization of acrylic acid onto the surface of MWCNTs in order to improve their dispersibility in water. 1H NMR, Raman spectroscopy, TEM, and TGA techniques were used to characterize the resulting functionalized MWCNTs. The graft…
Behavior of dry corrosion which is electrochemical reaction between Al-Mg-Si alloy 6063 and ethanol in gasoline has been investigated. Dry corrosion has not been observed in E3 (3% ethanol) and E10 (10% ethanol) at room temperature, but observed in E3 and E10 when a small amount of aluminum chloride had been added to…
