Authors: Tai Yong Peng , Li Pu , Zuo Wan Li
Published: March 2012

In this paper, we present an analytical model for thermoelastic damping (TED) in micromechanical resonators, which is based on entropy generation, a thermodynamic parameter measuring the irreversibility in heat conduction. The temperature field of thin beam with small vibration is obtained by solving governing equations of linear thermoelasticity. The analytical solution is derived from the entropy generation equation. This method of entropy generation can provide an accurate estimation of the quality factor in flexural resonators. The results are compared with Zener’s approximation and LR (Lifshitz and Roukes) method. It is shown that the analytical model described in this paper is valid to estimate the quality factor due to thermoelastic damping.

Published: March 2012

This research is aimed to achieve TPU-based TPU/PA6 blends which is equipped with both considerable mechanical properties and antistatic performance by blending with different portions of compatibilizer EVA-g-MAH and conductive carbon black with twin screw extruder. Results indicate that, the EVA-g-MAH not only improves the blend’s compatibility but also the mechanical properties. DSC results show that the gap between the glass transition temperatures of TPU and PA6 got shorten after adding EVA-g-MAH. The 70TPU/30PA6/15 EVA-g-MAH has better mechanical properties which are congruent with the findings of the SEM, and when this ratio was blended with different portions of conductive carbon black, their mechanical properties almost retain the same, but the blends obtain the antistatic property eventually. While lowering the production costs, the industrial application scope of TPU is widened especially the fields which have high requirement for antistatic property, such as electronic, medical, automotive, packaging, etc.

A Study of DNA Combing Speed in Fabricating Nanochannel ElectroPoration (NEP) Chips
Authors: Lin Samuel I. En
Published: March 2012

Electroporation through nanochannels has potential as a useful tool for cell transfection. This potential is due to: the low voltage required; the centralized distribution of the potential penetration; the fact that this method causes no harm to the cell membrane, and; the even expression pattern of the target gene after electroporation. Additionally, the stable production process and improved yield rate can reduce the cost of producing the nanochannels and thus make the commercialization of this technique more feasible. This study aims to investigate the relationship between the speed of DNA stretching and the yield rate of nanochannels. We found that when the length of nanochannels is 2 µm, the yield rate can exceed 90% at a stretching speed of 2.3 mm/s . With a similarly high yield rate, longer nanochannels (3 µm) displayed a wider range of stretching speed. We have determined that the stretching speed can influence the adhesion of DNA and the subsequent fabrication of nanochannels. Therefore, this speed must be appropriately controlled.

Published: March 2012

Antibacterial copper-rich phases such as ε-Cu were precipitated in copper-bearing antibacterial duplex stainless steels after antibacterial treatment. In this paper, the effects of antibacterial treatment on the corrosion resistance properties of copper-bearing antibacterial duplex stainless steels were investigated by electrochemical methods. The film-cover method was used to antibacterial tests.The results showed that as the antibacterial treatment temperature increased in the rang of 540~580 , the copper-rich precipitates grew faster and evolved from granular into rod-like. With the proportion of rod-like copper-rich phases in matrix increased, the resistant to pitting corrosion decreased and the positions of copper-rich phase precipitated were apt to become pitting nucleation source.The presence of ε-Cu and other copper-rich phases in passive film reduced the overall potential and passive film resistance, decreasing the stability of passive film. Antibacterial test showed that with the treatment temperature increased, the volume fraction and the uniformity of the distribution of copper-rich precipitates in the matrix first increased, then decreased, resulting in the changes in antibacterial properties of the steels, and 560 obtained the best antibacterial effect.

Published: March 2012

In this paper, the thermal oxidation behavior of TiAlCrSiN and AlCrTiN films coated on hastelloyX substrate, typically used for fuel nozzle in gas turbine engine application, have been studied. The thermal oxidation behavior at 950, 1050 and 1150 °C in controlled atmosphere were investigated. The surface appearance, microstructure, chemical composition and adhesion of films were investigated. The thermal oxidations were observed in all testing conditions showing oxide films at the surface with thicker oxide film at higher temperature. However, spalling of oxide scales was found in both coated and uncoated specimens at 1150°C suggesting the maximum working temperature of < 1150 °C for turbine engine applications. The critical loads corresponding to the full delamination of the thermal oxidation coated specimens were found to be higher than the non-thermal oxidation specimens. The effect of thermal oxidation on damage patterns during scratch tests, i.e. less chipping and cracking for thermal oxidation specimen, were also observed.

Published: March 2012

The effects of four impact modifiers: natural rubber (NR), poly (cis-1,4-isoprene) (IR), poly (acrylonitrile-co-butadiene) (NBR) and poly (ethylene-co-vinyl acetate) (PEVA), on the morphology, thermal and tensile properties by solution blending of poly (lactic acid) and 5 and 10 wt% impact modifier were investigated. Results showed that Youngs modulus and T.S. at break decreased in all PLA/impact modifier blends. In addition, Youngs modulus in all blends and T.S. at break in PLA/NR, PLA/IR and PLA/NBR blends was not significantly affected by the type and content of impact modifiers in the blends, but T.S. at break in PLA/PEVA blends was decreased by increasing the PVEA content from 5 wt% to 10 wt%. By contrast, the elongation at break significantly increased in all PLA/impact modifier blends and only PLA/NBR blends was affected by the content of impact modifier. Finally, the increase in ductility of all PLA/impact modifier blends confirmed the toughening capability of all impact modifiers. Thus, it is evident from tensile properties obtained indicated that PLA/impact modifier blends exhibit greater flexibility with all impact modifiers. Phase separation morphology of dispersion of impact modifier in PLA matrix indicating poor interfacial adhesion was observed. Tgand Tmof PLA/impact modifier blends exhibited almost the same as pure PLA, this suggested that there was no molecular interaction between PLA and impact modifiers, therefore, the PLA/impact modifier blends were immiscible.

Liver is a major target of nanoparticles accumulation. Here we have analyzed the liver function and activation of liver macrophages, which are sensitive to alteration of liver internal environment after repeated exposure to aluminum oxide nanoparticles. Sprague-Dawley rats where intraperitoneally injected very two days for 60 dyas with aluminum oxide nanoparticles (50mg/kg), non-nanoaluminum oxide (50mg/kg) and saline. After 60 days exposure, the concentrations of alanine aminotransferase and aspartic transaminase in plasma were significantly higher in nanoaluminum oxide group than non-nanoaluminum oxide and control groups. The number of ED-1+and GFAP+cells in liver of nanoaluminum oxide and non-nanoaluminum oxide groups increased significantly than control group. Compared with non-nanoaluminum oxide, aluminum oxide nanoparticles display potential adverse effects on the hypatocytes and biliary tract of rat liver and less stimulus to macrophages in liver than non-nanoaluminum oxide. It is suggested that part aluminum oxide nanoparticles avoided from phagocytosis by liver macrophages.

Aluminium alloy undergoes superplastic elongation in the order of a few thousands percent in elongation with low flow stresses. Superplastic forming processes can provide products with integral structure, light weight and superior strength, all of which are of particular importance for aerospace and automotive components. In the present study an analytical model was developed for a rectangular component by considering constant strain rate. This paper attempts to explore the superplastic behaviors of 8090 Al-Li alloy sheet into a rectangular die using blow forming technique. This has been done by a simple theoretical model and by numerical simulation using standard finite element code ABAQUS. The numerical and analytical results agree reasonably well for both the analytical and theoretical values with regard to variation in pressure and time.

Authors: Bao Jia , Ding Wei Dong , Lan Zhou
Published: March 2012

The photovoltaic power generation, as the effective complement of the existing grid, usually adopts the on-grid method，which needs to solve the frequency and phase tracking problem; otherwise, once the frequency and phase of the electric energy in the photovoltaic power generation system are different from those in the grid, the solar power will become an interference source of the existing grid. In the on-grid photovoltaic power generation simulate system, use a DC power supply and a resistance to simulate solar cells. The microcontroller outputs SPWM signals to control the status of the high-frequency power tubes in the inverter circuit，thus changing the DC energy power into AC power with the same frequency and phase of the grid. On the other hand, because the light and temperature will affect the outputting features of the solar cells, usually we require the solar cells work at the maximum power output point. In the system, we use the microcontroller to realize the maximum power point tracking algorithm. Seen from the experimental results, the quality of the output wave is good; by testing, the efficiency of the whole machine is above 80%.

The blast furnace coke plays four roles as exothermic agent, reducer, carburizer and framework. The former three roles can be played by other fuels, but the role as framework still can’t be played by other fuels by now. In order to ensure its skeleton role, it must be sure that the coke has enough high-temperature strength. This research uses KSJ decarbonizing electric furnace, drum-I and high temperature compressive testing machine to furthest simulate the coke’s actual actions in the blast furnace. The research indicates that comparing with the reactivity and strength index after reaction of coke GB4000-1996, the blast furnace coke’s high temperature compressive strength under a certain temperature and a certain carbon loss rate can give a more comprehensive evaluation of the quality of coke.
