Experimental Method All experiments were carried out in a high-pressure CO2 apparatus (Speed-SFE from Applied Separations) (see Figure 1) with a 300-mL extractor designed for a maximum pressure of 690 bar and a maximum temperature of 250 °C. The volume of the extractor had to be reduced to 50 mL by a metallic cylinder, which tightens to the extractor wall, because as preliminary tests showed the equilibrium cell has to be completely filled with material. Otherwise, diffusion is the limiting factor and time for reaching equilibrium was too long. The extraction vessel was filled with compressed CO2 by an air-driven pump at closed outlet valves and under static conditions, which means desired pressure and temperature; the cell was incubated for 15 h, maintaining these conditions to reach equilibrium. In preliminary experiments the equilibrium time of 15 h was determined to reach equilibrium. CO2 Sampling. At equilibrium a CO2 phase sample is taken by opening the outlet valve and expanding a certain amount of CO2-substance mixture into a cooling trap filled with toluene, which has the highest solubility for the measured substances under atmospheric conditions. The pure gaseous CO2 passes a rotameter, showing the actual flow rate, and a gas flowmeter for determining the expanded CO2 amount. The content of the cooling trap was filled up with toluene to 30 mL and analyzed by a gas chromatographic method using an electron capture detector (GC-ECD). With the mass of expanded CO2 and composition of the cooling trap solubility at a certain pressure and temperature was calculated. Sampling was repeated four times at a given pressure and temperature and the standard deviation was lower than 5%. Gas Chromatographic Method. The tolueneflame retardant mixture of CO2 sampling was analyzed in a gas chromatograph (HP 5890 Serie II) with an ECD using a capillary column (type HP-1, 12 m  0.2 mm  0.2 ím). The injector temperature was held constant at 290 °C and the detector temperature at 300 °C. The oven temperature was held constant at 290 °C. Calibration with different amounts of HBCD and TBBA in toluene has been done before determining the linear range of calibration line and retention time of substances 展开

Attaching the Sample Chuck You will need a #2 Phillips screwdriver for this step. Following the details shown in Fig. 2-4, install the sample chuck by first aligning the pins on the bottom of the sample chuck with the receptacles on the alpha- SE base. Then tighten the upper two captive thumb screws. Next, use the Phillips screwdriver to tighten the lower two captive screws. Don’t over tighten the screws! It will make it difficult to remove them in the future; just ensure that the screws are snug. Finally, connect the vacuum line from the sample chuck to the vacuum fitting on the alpha-SE base. Releasing the Z-stage Shipping Lock To access the Z-stage shipping lock, first loosen the captive screw on the lamp/shipping lock access door, then open the access door by rotating 180°, as shown in Fig. 2-5. To release the Z-stage shipping lock, stand in front of the ellipsometer and use your left hand to balance the weight of the Z-stage (you will feel it lift up slightly). It will be difficult to release the shipping lock if you apply too much or not enough upward force. Next, use your right hand to move the shipping lock to the operating position (to the right, see Fig. 2-6). If the lock is hard to move, you can use a tool to gain more leverage. The shipping lock will move about 1/3” [8mm] to the right. Checking the Lamp Check that the QTH lamp in fully seated in the lamp housing. The lamp is located behind the actuator screw (see Fig. 2-6) and has two white wires protruding from the back of the lamp. Simply push down on the lamp ensuring that the lamp is fully seated in the lamp housing. Rotate the lamp/shipping lock access door to the closed position and hand tighten the captive screw. 拒绝翻译软件,翻译软件我自己也会用 不是用翻译软件我就看不懂,只是,上来找人翻译就是希望翻译出比较容易看懂,不需要自己对照就可以看的说明书,如果用翻译软件,根本就词不达意,还是要自己对着原文件核实 既然用了那么多积分,就希望有相当的成果,如果用翻译软件混积分,那就是人品问题了 还有,某些人不要不懂乱说混积分 展开

During the preparation of the nano-products, these nano-units, such as nanoparticles, nanoclusters, nanowires and nanorods, can also self-assemble into the novel structural aggregates by several routes, including electron irradiation deposition [19], chemical vapor deposition [20], laser vaporization-condensation [21], charge transferring [22], an organic reagent-assisted method [23], solution-liquid-solid method [24] and catalytic vapor-liquid-solid growth [25]. With these routes, various nanoscale or microscale aggregates can demonstrate novel architectures, including tree-like, web-like, spherical, nanowire-like, network and fishbone-like aggregates. As a well-known method for producing the nanocapsules, however, arc-discharge has been rarely used to synthesize the aggregates self-assembled by the nanocapsules prepared simultaneously in arc-discharge. Nevertheless, it is possible that the arc-discharge can be developed into a new way to synthesize the aggregates. In the present work, we utilized arc-discharge technique with modified strategies, involving changing the hydrogen pressure, introducing gadolinium - aluminum alloy ingot as the anode and adjusting the elements percent of the anode according to their evaporation pressure, to synthesize a new type of nanocapsules, with intermetallic compound GdAl2 as core and amorphous Al2O3 as shell, which enlarge the family of the magnetic nanocapsules. At the same time, the regularly aligned three-dimensional macro-aggregates self-assembled by the nanocapsules without any template and catalyst were simultaneously synthesized in arc-discharge process. 展开

To show that HAX-1 degradation is part of the apoptotic process and any involvement Omi may have, we used the ucf-101 inhibitor. ucf-101 is a specific inhibitor of the proteolytic activity of Omi and has been described previously (13). When HK-2 cells were treated with cisplatin in the presence of ucf-101, the percentage of apoptotic cells decreased and the inhibitor significantly blocked HAX-1 degradation. This effect was more pronounced when a higher concentration of the inhibitor was used. To confirm the specificity of the inhibitor in this system and exclude the possibility that another protease rather than Omi is involved in HAX-1 cleavage, we used cell lines derived from mnd2 mice (9). The parent cell line (mnd2-MSCV) derived from mouse embryo fibroblasts has no detectable Omi proteolytic activity (9). The same cell line has been transfected with wild type human Omi cDNA (mnd2-MSCV-Omi) and expresses high levels of active Omi protein (14). We found that in mnd2-MSCV cells, when induced to undergo apoptosis with various stimuli, the number of apoptotic cells was very low. Furthermore, no detectable cleavage of HAX-1 was observed. This is in contrast with the mnd2-MSCV-Omi cells where apoptosis was robust, and HAX-1 levels were inversely proportional to the degree of apoptosis. This experiment clearly shows that Omi is solely responsible for HAX-1 cleavage, which is essential for apoptosis under the conditions used in these experiments. HAX-1 subcellular localization depends on cell type (21, 30) and has been reported to be present in the mitochondria, cytoplasm, or plasma membrane (10, 21, 22, 30). We performed subcellular fractionation to investigate where HAX-1 cleavage by Omi takes place. We found that, in HEK293 cells, HAX-1 was predominantly present in the mitochondria, and this localization did not change in response to apoptotic stimuli. This suggests that Omi can initiate apoptosis in the mitochondria by cleaving HAX-1 protein. This is in accord with a recent study that shows Omi can induce apoptosis in human neutrophils treated with TNF- without being released from the mitochondria (7). Although several studies clearly define HAX-1 as an anti-apoptotic protein, the mechanism of its function is unknown. HAX-1 has sequence similarity to Bcl-2 family of proteins (10, 22). 展开

Bimetallic dendrimer-encapsulated nanoparticles(DENs)are important materials,because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts.This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis,characterization,and applications as catalysts.Bimetallic DENs can be made mainly via three routes:co-complexation,sequential loading,and partial displacement.The research in bimetallic DENs has been significantly promoted by the advancement of characterization instruments.The performances of bimetallic DENs as homogeneous and heterogeneous catalysts in organic synthesis have been compared with both monometallic DENs and their physical mixtures.It is concluded that the synergistic electronic effect in bimetallic nanoparticles enhances their catalytic activities. 能翻译多少都可以的 展开

Transmission electron microscopy (TEM) was used to identify and characterize carbon nanotubes. Specimens for TEM observation were prepared by ultra-sonicating carbon nanotubes in alcohol, then dipping a TEM sample grid into the dispersion. Nitrogen adsorption isotherms of nanotube samples were measured at 77.5 K by an ASAP 2010 volumetric sorption analyzer (Micromeritics) with addi- tional options for the micropore analysis. The volume of adsorbed nitrogen at 77.5 K was measured as a function of 25 the equilibrium pressure over a range from 10 Torr to the saturation vapor pressure. Prior to adsorption measure- ments, samples were outgassed under vacuum at 573 K for 3 h. The pore size distributions (PSD) of samples were obtained by analyzing the isotherm with BJH equation. To check any significant chemical modification, the raw and conpurified sample was analyzed by X-ray photoelectron spectroscopy (XPS), respectively. Photoelectron spectra of samples were measured using a PHI5300 X-ray photoelec- tron spectrometer (PE Corp.) with Al Ka source. The spectra were recorded at room temperature under high vacuum. All binding energies (BE) were corrected for sample charging using the BE of C as an external 1s standard (284.6 eV). All data were analyzed with the aid of an Applle Series 3500. Thermo-gravimetric analysis (TGA) was used to determine the content of the Fe catalyst in the sample, and a CAHN2000 thermo-gravimetric analyzer was used to characterize weight loss during oxidation of the samples in air with heating to 11008C at a rate of 108C/min. 展开
