| 1 | Combining extractive heterogeneous-azeotropic distillation and hydrophilic pervaporation for enhanced separation of non-ideal ternary mixtures显示文摘The separation of non-ideal mixtures using distillation can be an extremely complex process and there continues to be a need to further improve these techniques.A new method which combines extractive heterogeneous-azeotropic distillation(EHAD)and hydrophilic pervapora-tion(HPV)for the separation of non-ideal termary mixtures is demonstrated.This improved distillation method combines the benefits of heterogeneous-azeotropic and extractive distillations in one column but no added materials are needed as is usually the case with pervaporation.The separation of water-methanol-ethyl acetate and water-methanol-isopropyl acetate mixtures were investigated to demonstrate the accuracy of the combined EHAD/HPV technique.There is not currently an established treatment strategy for the separation of the second mixtures in the literature.These separation processes were rigorously modelled and optimized using a professional flowsheet.The objective functions were total cost and energy consumption and heat integration was also investigated.The verification of the process modelling was carried out using laboratory-scale measurements.Extractive heterogeneous-distillation combined with methanol dehydration was found to be more efficient than conventional distillation for the separation of these highly non-ideal mixtures. | Eniko Haaz Botond Szilagyi Daniel Fozer Andras Jozsef Toth | 2020 | Frontiers of Chemical Science and Engineering2020，14，5： | 2 |
| 2 | Morphological and microcirculatory evaluation of the rat testis after detorsion with or without a capsular release with a tunica vaginalis flap显示文摘阴囊的扭转可以导致严肃的局部缺血,并且生存能力取决于扭转的持续时间和 ischemia-reperfusion 的效果。阴囊的解压缩和 tunica vaginalis 拍动应用程序技术被 Kutikov 等在 2008 介绍。我们试图在一个老鼠模型在阴囊的 microcirculation 和 hemorheological 参数上检验这个方法的影响。六只成年老鼠经历了双边的阴囊的探索。睾丸的 Intravaginal 扭转被 720 ° 创造;为 2 h 的双方上的旋转。在 detorsion 以后,正确睾丸经历了 tunica albuginea 切口和 tunica vaginalis 拍动申请。阴囊的 microcirculation 被监视, hematological 参数,红血球 deformability,和聚集是坚定的。大小在扭转前后被执行,直接在 detorsion 以后,在 1 st -2 nd 和 8 th 手术后的白天。在最后采样以后,睾丸被移开为组织学的考试决定他们的体积。microcirculatory 参数表明了睾丸之间的细微差别。睾丸与中间的地区相比提高了的左(nondecompressed ) 的顶端的地区(P <0.05 ) 。在 2 nd 和 8 th 白天,睾丸的 microcirculation 使正常化然而并非同等地。红血球聚集和 deformability 由 8 th 白天。睾丸经历了萎缩和上皮的坏死,但是减压的体积更低(1.07 ±0.08 对 1.25 ±0.31 ) 。组织学地,在上皮的损坏分数在之间没有重要差别减压并且 nondecompressed 睾丸。在结论, 2-h 局部缺血两个都在阴囊的 microcirculation,在体积的减小,在 hemorheological 参数的变化和严肃的上皮的坏死导致了改变在减压并且没有显著差别的 nondecompressed 睾丸。 | Tamas Jozsat Zoltan Klarik Ferenc Kiss Eniko Toth Anita Mester Zoltan Hargitai Yi-Che Changchien Magdalena Fossum Norbert Nemeth | 2016 | Asian Journal of Andrology2016，18，3： | 2 |

| 4 | Effect of silver-nanoparticles generated in poly(vinyl alcohol)membranes on ethanol dehydration via pervaporation显示文摘Pervaporation is an important membrane separation method of chemical engineering.In this work,silver-nanoparticles-poly(vinyl alcohol)nanocomposite membranes(AgNPs-PVA)are produced for the sake of improving its potentials for pervaporation of ethanol–water mixture so that the usual opposite trend between membrane selectivity and permeation can be reduced.The nanocomposite membranes are fabricated from an aqueous solution of poly(vinyl alcohol)with silver nanoparticles via the in-situ generation technique in the absence of any reducing agent.Successful generation of the nano size silver is measured by the UV–vis spectrum showing a single peak at 419 nm due to the plasmonic effect of silver nanoparticles.Our nanocomposite AgNPs-PVA membranes are characterized using scanning electron microscope(SEM),Fourier-transform infrared(FT-IR)spectroscopy,X-ray diffraction and thermogravimetric analysis(TGA).The pervaporation tests of our new AgNPs-PVA membranes show good results since at a higher temperature and higher ethanol concentration in the feed,the prepared membranes are highly permeable for the water having stable selectivity values and therefore our membranes show better performance compared to that of the other PVA-based nanocomposite membranes. | Asmaa Selim Andras Jozsef Toth Daniel Fozer Eniko Haaz Nóra Valentínyi Tibor Nagy Orsolya Keri Lászlo Péter Bakos Imre Miklós Szilágyi Peter Mizsey | 2019 | Chinese Journal of Chemical Engineering2019，27，7： | 0 |
