1CHARACTERIZATION OF POWDER FLOWABILITY USING MEASUREMENT OF ANGLE OF REPOSE显示文摘In response to the need in industry for a quick and reproducible method of measuring the flowability o powders in processes involving transport and storage, the apparently simple idea of measuring angle of repose has bee revived. The simple tester first used has evolved over a number of years into the present version which is shown to b capable of handling quite small samples of powders that are even slightly cohesive. Experimental data are presented an results shown to compare consistently with the better known Hausner ratio.D. Geldart E. C. Abdullah A. Hassanpour L. C. Nwoke I.

2Oral manifestation in inflammatory bowel disease:A review显示文摘Inflammatory bowel diseases(IBDs),including Crohn’s disease(CD)and ulcerative colitis,not only affect the intestinal tract but also have an extraintestinal involvement within the oral cavity.These oral manifestations may assist in the diagnosis and the monitoring of disease activity,whilst ignoring them may lead to an inaccurate diagnosis and useless and expensive workups.Indurated tag-like lesions,cobblestoning,and mucogingivitis are the most common specific oral findings encountered in CD cases.Aphthous stomatitis and pyostomatitis vegetans are among non-specific oral manifestations of IBD.In differential diagnosis,side effects of drugs,infections,nutritional deficiencies,and other inflammatory conditions should also be considered.Treatment usually involves managing the underlying intestinal disease.In severe cases with local symptoms,topical and/or systemic steroids and immunosuppressive drugs might be used.Kamran B Lankarani Gholam Reza Sivandzadeh Shima Hassanpour 2013World Journal of Gastroenterology2013,19,46:10
3高强电场中液滴静电运动特性显示文摘针对油田生产中含表面活性剂原油电脱水极为困难,缺乏理论指导的现状,采用动态微观实验的方法,研究含表面活性剂的油水系统中液滴在电场力作用下聚并排液的情况,计算液滴的聚结时间,并观测液滴发生形变直至破裂时各个阶段的现象。结果表明,表面活性剂可引起液滴界面排斥力上升,聚并过程中液面出现形变,降低液滴聚结速度。此外,液滴表面所吸附的表面活性剂分子会加剧液滴形变率,降低液滴破裂所需临界场强,并改变液滴破裂机制,增加了次级微小液滴的产生。须严格控制电场强度,以避免液滴变形破裂,提高聚结效率,确保电脱水的效果。张黎明 张凯 李晓帆 Mojtaba Ghadiri Ali Hassanpour 2011石油学报2011,32,3:10
4油中水滴静电聚并微观机理研究显示文摘利用电场对多相体系进行分离处理广泛应用于石油化工等行业,电场力作用下液滴间的相互运动聚并是聚结的基础和前提条件.本文从液滴间静电力学模型出发,通过动态微观实验对液滴的聚并过程进行了完整的记录和分析,确定不同实验条件下液滴的聚并方式和角度,以及液滴从静止状态到发生相对运动时的临界条件.结果发现当两等大液滴间距与液滴半径之比大于1时,液滴间中心连线与电场力夹角θ<54.7°或θ>125.3°,两液滴间作用力表现为吸引力,当液滴间距较小时,能产生聚结的最大倾角增大为81.3°.液滴间相对距离增大时,移动临界电场强度迅速升高,较大液滴发生相对移动所需的场强低于小颗粒液滴.实验结果验证了相关理论,进一步完善了静电聚结机理.张黎明 张凯 Majtaba.Gadiri Ali Hassanpour 陈小飞 2011应用基础与工程科学学报2011,19,6:4
5Biomass-derived nonprecious metal catalysts for oxygen reduction reaction: The demand-oriented engineering of active sites and structures显示文摘Oxygen reduction reaction(ORR)is an important electrochemical process for renewable energy conversion and storage applications such as fuel cells and metal-air batteries.ORR is sluggish in kinetics and requires a large amount of platinum group metal(PGM)-based catalysts to facilitate its slow reaction rate.Application of precious metals raises the cost and decreases the competitivity of these devices in the market.To address this challenge,PGM-free ORR catalysts have been intensively investigated as an alternative to replace the PGM-based catalysts and to promote the deployment of ORR-related applications.In particular,the biomass holds promising potential to be used as the precursor material for PGM-free ORR catalysts.This pathway has gained more and more attention in recent years.In this review,recent advances regarding biomass-derived ORR catalysts are summarized with a focus on the rational design of both active sites and porous structures which are the two key factors in determining ORR performance of catalysts.At the end,the perspectives of development of biomass-derived catalysts is discussed.Lei Du Gaixia Zhang Xianhu Liu Amir Hassanpour Marc Dubois Ana CTavares Shuhui Sun 2020Carbon Energy2020,2,4:3
6Efficacy and safety of micropulse laser trabeculoplasty for primary open angle glaucoma显示文摘AIM: To evaluate the efficiency and safety of micropulse laser trabeculoplasty(MLT) for primary open angle glaucoma(POAG) patients. METHODS: Retrospective study. POAG patients undergoing MLT in Peking University Third Hospital from June 2016 to November 2017. Seventy-two eyes of 72 POAG patients were enrolled. Only one eye of each patient was treated by MLT. The intraocular pressure(IOP) before MLT and at 1 d, 1, 4, 12 and 24 wk and glaucoma medication before and after treatment were compared.RESULTS: The IOP was 20.6±5.9 mm Hg before MLT and 20.8±6.8 mm Hg at 2 h after MTL. The IOP at 1 d, 1, 4, 12 and 24 wk was 17.9±4.4, 18.0±4.3, 17.5±3.4, 17.0±2.7, and 16.5±2.9 mm Hg, respectively. The IOP before and after MLT demonstrated a statistically significant difference by ANOVA analyses(F=5.797, P<0.001). Least significant difference t-tests showed there was no statistically significant difference between pre-MLT IOP within 2 h after MLT(P=0.207). The statistically significant difference was confirmed between the pre-MLT IOP at 1 d, 1, 4, 12 and 24 wk after MLT(P=0.006, 0.009, 0.001, <0.001, <0.001, respectively). The number of glaucoma medications before MLT was 1.7±1.4 and 1.5±1.4 24 wk after MLT with a significantly statistical difference(t=2.219, P=0.031)CONCLUSION: MLT is effective and safe for POAG patients. No patient experienced IOP spikes after MLT. The IOP 6 mo after treatment decreased significantly with less glaucoma medication.Ying Hong Si-Jia Song Bo Liu Kiana Hassanpour Chun Zhang Nils Loewen 2019International Journal of Ophthalmology(English edition)2019,12,5:2
