Abstract— The fabrication technique for color OLED panels by means of wettability‐controllable hole‐injection material (HIM) and a photocatalytic lithography method achieves both precise ink‐jet printing and long‐lifetime devices. The technique enables us to selectively change the non‐wetting surface of a hole‐injection layer (HIL) of metal‐oxide nanoparticles (MONPs) into a wetting surface without damage to the device performance. Wetting patterns formed by this method with photocatalyst‐coated photomasks made it possible to print emission material with patterns of precisely 98‐μm widths on the hole‐injection layer. A fluorescent green‐emitting device fabricated with an HIM of MONPs by the photocatalytic treatment exhibited a long lifetime of 365 hours at30,000 cd/m2, which can be extrapolated to a lifetime of more than 110,000 hours at 1000 cd/m2, assuming an acceleration coefficient of 1.7. A two‐color device and a monochrome passive‐matrix panel were also successfully fabricated. The two‐color device emitted light without the mixing of colors. The monochrome panel displayed alphabetical characters with good uniformity and no flaws. 相似文献

Crystal growth of rod-shaped β-LiAlO2 was previously reported by us, and the rod-shaped β-LiAlO2 crystals were 1.5 μ in diameter and 10 to 15 μm long. In the present study needle-shaped β-LiAlO2 crystals which were thinner and had larger aspect ratios (length/diameter) than the rodshaped β-LiAlO2 crystals were grown by using LiOH–Al2 O3 –Al(OH)3 –NaOH as the raw material. These crystals were 0.7 to 1 μm in diameter, 9 to 13 μm long, and had aspect ratios of about 10 to 13. 相似文献

The effect of mix proportion, leachant pH, curing age, carbonation and specimen making method etc. on the leaching of heavy metals and Cr(VI) in fly ash cement mortars and cement-solidified fly ashes has been investigated. In addition, a method for reducing the leaching of Cr(VI) from cement-solidified fly ashes is proposed. The results mainly indicate that: (1) either Portland cement or fly ash contains a certain amount of heavy and toxic metals, and the leaching of them from hardened fly ash incorporated specimens exists and is increased with fly ash addition and water to cement ratio; (2) the leachability of some heavy metals is greatly dependent on leachant pH; (3) when carbonation of cement mortars occurs the leaching of chromium ions is increased; (4) the amount of heavy metals leached from cement-solidified fly ashes depends more on the kind of fly ash than their contents in fly ash; and (5) with ground granulated blast furnace slag addition, the leaching of Cr(VI) from solidified fly ashes is decreased. 相似文献

In the present study, clinical findings of 15 patients with cardiac sarcoidosis presenting as dilated cardiomyopathy were compared with those of 30 consecutive patients with idiopathic dilated cardiomyopathy. The sarcoidosis patients had different clinical features, including female predominance, a high incidence of grave conduction disturbance and abnormal wall thickness, uneven wall motion abnormalities, and perfusion defects preferentially affecting the anteroseptal and apical regions, and poor prognosis compared with those with idiopathic dilated cardiomyopathy. 相似文献

We examined the changes in pulmonary function values in 27 patients who underwent a lobectomy due to cystic lung disease and compared the results regarding such factors as disease type, age at operation, and preoperative infections. Percent vital capacity (%VC) decreased immediately after lobectomy, but recovered to normal values within 2 postoperative years and remained within or above the normal range. The ratio of residual volume to total lung capacity (RV/TLC) rose temporally with the increase in %VC, but then remained normal after 2 postoperative years. There was no difference in %VC and RV/TLC between diseases, while bronchial atresia showed a significantly lower correlation with percent of forced expiratory volume at 1 s. The older group operated upon at over 4 years of age and the group that had infections before operation showed relatively low %VC and high RV/TLC. Some patients demonstrated extremely low %VC along with funnel chest deformities. Our study suggests that overinflation of the remaining lung compensates VC in the early period after lobectomy while subsequently alveolar multiplication occurs. Factors affecting compensatory lung growth were considered to be operation later than 4 years of age, preoperative infection, and a thoracic deformity. 相似文献

CD38, a type II transmembrane glycoprotein, behaves as a catalytically active transporter responsible for ectocellular generation of cyclic ADP-ribose (cADPR) from NAD+ and for subsequent influx of cADPR across membranes [Franco, L., Guida, L., Bruzzone, S., Zocchi, E., Usai, C. and De Flora, A. (1998) FASEB J. in press]. cADPR regulates intracellular calcium homeostasis by releasing calcium from responsive stores. The cADPR-transporting function of CD38 requires channel-generating oligomeric forms of the protein rather than the 46 kDa monomers that have been described so far in CD38+ cells. Here we demonstrate that CD38, both in reconstituted proteoliposomes and in CD38-transfected HeLa cells, is a mixture of catalytically active monomers, homodimers and homotetramers. A soluble recombinant form of CD38 corresponding to its ectocellular region proved to be monomeric. Thus, association of native CD38 with either artificial or natural membranes seems to result in a reversible juxtaposition of monomers suitable to cADPR-transporting activity. 相似文献

A mixture (50 microl) consisting of Escherichia coli cells, chrysotile fibers, and 200 mM NaCl was added to 2% agar plates and spread with a plastic stir stick. An apparatus was developed to generate a sliding friction force on the surface of the plate by applying a fixed vertical reaction force to the stir stick while turning the plate. This operation was defined as chrysotile-exposure. The number of living cells, expressed as colony forming units, was reduced in proportion to the duration of chrysotile-exposure. The decrease in the number of living cells was greater following 120 s of chrysotile-exposure than crocidolite- or amosite-exposure. There was no decrease in the number of living cells exposed to chrysotile on 0.5% agar even after 120 s. The number of living cells after chrysotile-exposure decreased with increasing chrysotile concentration. Leakage of beta-galactosidase from cells increased with increasing duration of chrysotile-exposure. Transmission and scanning electron microscopy observation of E. coli revealed chrysotile penetration of the cell membrane. These results show that chrysotile fibers destroy cells by penetration. The driving force for the chrysotile penetration was the sliding friction force, as the number of living cells following chrysotile-exposure decreased with increasing exposure times, but did not decrease following chrysotile-exposure on a low concentration of agar, which provided cells with low sliding friction force. 相似文献

The daily dietary intake of aluminum was estimated through a total diet study from 1996 to 1998. In ten institutes, total diet study samples were prepared and their aluminum concentration was determined. The average daily intake of aluminum was 3.5 mg and the range was 1.8-8.4 mg. The validity of the analytical result was supported by analyses of certified reference materials. 相似文献

To understand the role of composition in the oxidation behavior of Ti–Mo system and to evaluate the extent of oxygen ingress into the metal substrate during high temperature exposure, a compositionally graded Ti–xMo specimen (0 ≤ x ≤ 12 wt% Mo) was prepared using an additive manufacturing technique, solutionized and then subjected to oxidation tests at 650 °C for different exposure times. The depth of oxygen diffusion, across the composition range, was assessed via change in the local hardness and the results were coupled with quantitative measurement of the oxygen concentration. The concentration of O in the α phase was reduced by 90 % after a short distance of 16 μm from the metal/oxide interface while it remained more or less the same in β phase. The solubility of Mo in α phase also approached zero near the surface as O changed the partition coefficient of this element between α and β phases. It was shown that the addition of Mo reduces the solubility of O in the metal substrate which in turn retards the transition point from parabolic to the linear oxidation stage. 相似文献

The Young’s modulus of FeO scales formed on a pure iron bar was measured at temperatures between 973 and 1273 K. The FeO was formed with charging 4.2 × 10−4 mol of oxygen gas five times into a reaction chamber. During the growth of FeO, a sinusoidal vibration signal was applied to the bar. The vibration force and the acceleration of the oxidised iron bar were measured in situ in order to obtain resonance frequencies. The Young’s modulus of FeO, as estimated at oxidation temperatures of 973, 1173, and 1273 K, was 98.6, 75.9, and 83.4 GPa, respectively. 相似文献
