1Microwave Synthesis of Large Few-Layer Graphene Sheets in Aqueous Solution of Ammonia显示文摘Few-layer graphene (FLG) sheets with sizes exceeding several micrometers have been synthesized by exfoliation of expanded graphite in aqueous solution of ammonia under microwave irradiation, with an overall yield approaching 8 wt.%. Transmission electron microscopy (in bright-field and dark-field modes) together with electron diffraction patterns and atomic force microscopy confirmed that this graphene material consisted mostly of mono-, bi- or few-layer graphene (less than ten layers). The high degree of surface reduction was confirmed by X-ray photoelectron and infrared spectroscopies. In addition, the high stability of the FLG in the liquid medium facilitates the deposition of the graphene material onto several substrates via low-cost solution-phase processing techniques, opening the way to subsequent applications of the material.Izabela Janowska Kambiz Chizari Ovidiu Ersen Spyridon Zafeiratos Driss Soubane Victor Da Costa Virginie Speisser Christine Boeglin Matthieu Houllé Dominique Bégin Dominique Plee Marc-Jacques Ledoux Cuong Pham-Huu 2010Nano Research2010,3,2:22
2不同土地覆被格局情景下多种生态系统服务的响应与权衡--以雅砻江二滩水利枢纽为例显示文摘在二滩水库集水区,按照当地生态政策发展以坡度为指标构建了10种未来土地覆被格局情景,研究生态系统减轻水库泥沙淤积、减轻水库面源污染、产水发电服务及价值对未来覆被格局的响应程度,并兼顾相关产业收益的变化,权衡各种情景格局的服务效益,优选利益相关方福祉提升幅度最大的情景格局。结果表明:1)现有土地覆被格局对减轻水库泥沙淤积功效的发挥不合理,而以退耕还林政策指导区域土地覆被格局变化,对集水区减轻河道和水库泥沙淤积具有较好功效。10种情景下,保沙价值的高低关系同入库泥沙量正好相反,遵循'随地表林地和草地面积比例的增加,保沙价值增加'的规律。随产沙总量的增加,高产沙强度像元呈现从水库周边逐渐向中上游蔓延的趋势。2)退耕还林政策单纯以坡度作为指标,指导土地覆被的转化,对集水区减轻水环境磷素非点源污染功效较差。除了全为未利用地覆被的情景10,余下9类情景模拟的入库磷素量及过滤磷素经济价值的高低关系完全一致,呈农田>草地>林地的规律。随入库磷素总量的增加,高强度磷素输出像元从雅砻江流域源区和大河湾区,逐渐蔓延扩散至集水区整个水网。3)随着集水区地表林地覆盖面积比例的减少,集水区生态系统总发电净利润值增加,且高净利润像元呈现从冕宁和喜德县的东部逐渐向整个集水区东南部乃至整个下游蔓延的趋势。4)从减轻对环境的负效应以及提升利益相关方福祉的角度,以坡度6°上下划分林地和耕地的情景5和以坡度15°和6°为阈值划分林草农的情景3为除极端的情景外,综合指标提升最高的两种情景。葛菁 吴楠 高吉喜 王晓辉 苏德毕力格 张晨 Driss Ennaanay 田美荣 2012生态学报2012,32,9:12
3Duodenal variceal bleeding with large spontaneous portosystemic shunt treated with transjugular intrahepatic portosystemic shunt and embolization: A case report显示文摘BACKGROUND Duodenal variceal bleeding is a rare cause of gastrointestinal bleeding. The most common site is the duodenal bulb. It is usually detected endoscopically but it can be very challenging to diagnose if it is located distal to the second part od duodenum. The pre- transjugular intrahepatic portosystemic shunt (TIPS) presence of spontaneous portosystemic shunt (SPSS) was found to be associated with an increased risk of early morbidity and mortality after TIPS placement. CASE SUMMARY A 43-year-old cirrhotic male presented with melena for three days. Upper endoscopy was performed and showed active blood oozing from the distal duodenum concerning for ectopic duodenal varix. A computed tomography (CT) angiogram was performed and showed an enlarged cluster of venous collaterals around the distal duodenum. He underwent TIPS placement. He had another episode of melena three days later. Push enteroscopy with injection sclerotherapy into the duodenal varices was performed with no success. A repeat CT angiogram showed occluded TIPS shunt. Therefore, a TIPS revision was performed and there was an extensive portal venous thrombosis with a large shunt between the inferior mesenteric vein and left renal vein via the left gonadal vein. Thrombectomy and TIPS shunt balloon angioplasty was performed, followed by embolization of the portosystemic. The melena was resolved, and patient was discharged with arranged hepatology follow up. CONCLUSION It importance to look and embolize the SPSS shunts in patients with early TIPS dysfunction and recurrent duodenal variceal bleeding.Rohit Anand Saad Emhmed Ali Driss Raissi Wesam M Frandah 2019World Journal of Radiology2019,11,8:7
4Emotion processing in Parkinson's disease: a blood oxygenation level-dependent functional magnetic resonance imaging study显示文摘Parkinson's disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease.Mohammed Benzagmout Sa?d Boujraf Badreeddine Alami Hassane Ali Amadou Halima El Hamdaoui Amine Bennani Mounir Jaafari Ismail Rammouz Mustapha Maaroufi Rabia Magoul Driss Boussaoud 2019Neural Regeneration Research2019,14,4:6
5不同土地利用/覆被情景下生态系统减轻水库泥沙淤积的服务能力与经济价值模拟显示文摘以ArcGIS9.2为平台,构建了生态系统减轻水库泥沙淤积服务物质量和价值量评估模型。整合2000年的相关数据将此模型应用于二滩水库,并模拟了10种不同土地利用/覆被情景下集水区生态系统该项服务的能力和在水库使用年限内服务总价值的响应。结果表明:2000年,二滩水库集水区土壤保持量12.1亿.ta-1,高值区分布于雅砻江干流和支流水网附近。泥沙输移比在河道附近和水库周边较高。水库周边是最为主要的保沙区。水库使用年限内,集水区对于减轻二滩水库泥沙淤积服务总价值27.53亿元。集水区内不同结构类型的土地利用/覆被情景对保沙能力所产生的影响各异,模拟保沙量符合林地>草地>裸地>农田规律,农田保沙能力最弱,是二滩水库最为主要的产沙源。吴楠 高吉喜 苏德毕力格 罗遵兰 Driss Ennaanay Guillermo F.Mendoza 李岱青 田美荣 2009生态学报2009,29,11:6
6基于格局和过程的流域生态系统减轻入库泥沙服务及价值——以雅砻江二滩水库为例显示文摘基于径流泥沙的运移过程,构建了沿汇流路径,结合不同土地覆被对泥沙拦截能力系数模拟每个像元截留泥沙使其不进入水库量的模型.结合单位体积淤泥的清淤费用、水库使用年限及贴现率进行构建价值量模型,并在二滩水库的集水区进行了模型的运用.结果表明:2000~2005年,土地覆被格局的变化主要体现在雅砻江中上游草地向林地的转化和下游亲水区林地向农田和草地的转化.由此影响到2000和2005年土壤侵蚀总量变化不大,但2005年集水区向水库输沙总量有较大增加,农田也成为二滩水库最为主要的产沙源.多数被侵蚀的土壤在向二滩水库的运移过程中被各类生态系统截留,截留泥沙量的高值集中分布于二滩库区周边.林地平均截留泥沙绝对量较低,截留泥沙的能力未能得到有效发挥.集水区对于减轻进入二滩水库泥沙服务的总经济价值在2000和2005年分别达到442.2和785.8亿元.吴楠 苏德毕力格 高吉喜 张晨 葛菁 Ennaanay Driss 田美荣 2011中国环境科学2011,31,10:6
7Parallel transjugular intrahepatic portosystemic shunt with Viatorr^(®)? stents for primary TIPS insufficiency:Case series and review of literature显示文摘BACKGROUND Transjugular intrahepatic portosystemic shunts(TIPS) can alleviate complications of portal hypertension such as ascites and variceal bleeding by decreasing the portosystemic gradient.In limited clinical situations,parallel TIPS may be only solution to alleviate either variceal bleeding or ascites secondary to portal hypertension when the primary TIPS fails to do so.Data specifically addressing the use of this partially polytetrafluoroethylene covered nitinol stent(Viatorr~?) is largely lacking despite Viatorr~? being the current gold standard for modern TIPS placement.CASE SUMMARY All three patients had portal hypertension and already had a primary Viatorr~?TIPS placed previously.All patients have undergone failed endoscopy to manage acute variceal bleeding before referral for a parallel stent(PS).PS were placed in patients presenting with recurrent variceal bleeding despite existence of a widely patent primary TIPS.Primary stent patency was verified with either Doppler ultrasound or intra-procedural TIPS stent venography.Doppler ultrasound follow-up imaging demonstrated complete patency of both primary and parallel TIPS.All three patients did well on clinical follow-up of up to six months and no major complications were recorded.A review of existing literature on the role of PS in the management of portal hypertension complications is discussed.There are three case reports of use of primary and PS Viatorr~? stents placement,only one of which is in a patient with gastrointestinal variceal bleeding despite a patent primary Viatorr~? TIPS.CONCLUSION Viatorr~? PS placement in the management of variceal hemorrhage is feasible with promising short term patency and clinical follow-up data.Driss Raissi Qian Yu Michael Nisiewicz Steven Krohmer 2019World Journal of Hepatology2019,11,2:5
8生态系统减轻水环境磷素非点源污染服务及价值——以雅砻江二滩水库为例显示文摘以ArcGIS9.2为平台,构建了生态系统减轻集水区出口受纳水体非点源污染服务物质量和价值量评估模型。包括模拟集水区范围,根据各种土地利用/覆被类型的污染物质输出及过滤污染能力系数,沿汇流路径,模拟集水区内每个栅格像元被植被移除而未进入水环境的污染物质量空间分布特征。价值量模型结合期望水质标准和净化污染物的边际成本进行计算。以磷素作为指示污染物,在二滩水库的集水区进行了模型的运用。结果表明:二滩水库集水区南部的河道附近是水文敏感区。其中盐源县腹地的农作区、西昌市与冕宁县,以及集水区最北端的称多县、中部的甘孜县等部分地区是是磷素关键污染源区。2000年被集水区生态系统过滤移除而未进入水环境的磷素污染物质总量达到978.90t.a-1,占关键污染源区指数总量的81.88%。林地生态系统服务价值贡献率最高。2000年集水区生态系统对于减轻其出口受纳水体磷素非点源污染服务的总价值为1370.18万元。吴楠 苏德毕力格 高吉喜 Driss Ennaanay Guillermo F.Mendoza 罗遵兰 李岱青 田美荣 2010生态学报2010,30,7:5
9典型饮用水源地非点源污染的分布式模拟——以滁州市城西水库为例显示文摘城西水库(现改名西涧湖)是滁州市唯一地表水源,非点源污染已成为其水质污染的重要原因。基于土地覆被格局,依据非点源污染物质的产生、截留、汇流过程,构建了模拟每个栅格上污染物质向受纳水体的输出贡献量和被各种土地覆被截留量的物理过程模型。以磷素为例,对城西水库流域进行模拟。结果表明:2000和2010年,流域向城西水库输出总磷量分别达到2 580.38和2 461.20kg。库体西北部的市农科所、城郊居委会、水产研究所等地对水质危害最大。多数磷素在向库体的运移过程中被各类土地覆被有效的截留,总量在2000和2010年分别达到5 774.49和5 422.36kg,占流域磷素总负荷的69.1%和68.8%。由于目前土地覆被布局的不尽合理,林地和草地对磷素的截留能力未能充分发挥。建议在流域水文敏感区布设林草缓冲带,将有效减少水库磷素的接纳量。吴楠 周晓铁 王晓辉 葛菁 高吉喜 冯朝阳 Driss Ennaanay 2014长江流域资源与环境2014,23,5:4
10Catalytic performances of Ni/mesoporous SiO_2 catalysts for dry reforming of methane to hydrogen显示文摘Several mesoporous silicas with different morphologies were controllably prepared by sol-gel method with adjustable ratio of dual template,and they were further impregnated with aqueous solution of nickel nitrate,followed by calcination in air.The synthesized silica supports and supported nickel samples were characterized using N_2-adsorption/desorption,X-ray diffraction(XRD),H_2 temperature-programmed reduction(H_2-TPR),Scanning electron microscope(SEM),Transmission electron microscope(TEM) and thermo-gravimetric analysis(TGA-DTG) techniques.The Ni nanoparticles supported on shell-like silica are highly dispersed and yielded much narrower nickel particle-size than those on other mesoporous silica.The methane reforming with dioxide carbon reaction results showed that Ni nanoparticles supported on shell-like silica carrier exhibited the better catalytic performance and catalytic stability than those of nickel catalyst supported on other silica carrier.The thermo-gravimetric analysis on used nickel catalysts uncovered that catalyst deactivation depends on the type and nature of the coke deposited.The heterogeneous nature of the deposited coke was observed on nickel nanoparticles supported on spherical and peanut-like silica.Much narrower and lower TGA derivative peak was founded on Ni catalyst supported on the shell-like silica.Fei Huang Rui Wang Chao Yang Hafedh Driss Wei Chu Hui Zhang 2016Journal of Energy Chemistry2016,25,4:4

12用于乙苯氧化脱氢制苯乙烯铝-硼催化剂:铝硼组成及制备方法对催化剂性能的影响(英文)显示文摘采用溶胶-凝胶(SG)法合成了不同摩尔比的Al-B催化剂(Al-10B与Al-35B).在450-500℃,乙苯(EB)接触时间为0.54 g-cat.s.cm-3的条件下,在氧气和水蒸气存在下对这些催化剂进行催化乙苯脱氢反应.利用NH3-TPD质谱分析了Al-B催化剂的酸性.扫描电镜图像显示,硼在氧化铝中负载量达15%(Al-15b)时仍分布很好,而在较高的硼含量(Al-25B和Al-35B)催化剂中观察到硼聚集.从本质上讲,在Al和Al-10B催化剂上观察到强度非常弱(Tmax≤125℃)的酸位,使得EB转化率和苯乙烯产率很低.另一方面,在Al-25B和Al-35B催化剂酸位较弱(Tmax≤180℃),因而EB转化率较高.然而,在弱-中等强度酸位的Al-15B催化剂上可以得到较高的苯乙烯产率(43.2%)和合理的EB转化率(46%).另外,采用共沉淀法(COP)和浸渍法(IMP)合成了Al-15B催化剂.IMP和COP催化剂的NH3-TPD-质谱分析结果发现,与NOx形成有关的酸位点在500℃时将EB转化率分别提高到66%和63%.然而,Al-B SG催化剂中的这些酸位降低,使得500℃时EB转化率为50%.当EB转化率为50%时,在Al-B IMP,Al-B COP和Al-SG催化剂上苯乙烯选择性分别为73%,82.5%和84%.因此,不同方法制备的Al-B催化剂,会产生不同强度和密度的酸位,从而影响苯乙烯的形成.Nagaraju Pasupulety Muhammad A.Daous Abdulrahim A.Al-Zahrani Hafedh Driss Lachezar A.Petrov 2019Chinese Journal of Catalysis2019,40,11:3
13生态系统供水发电服务评估及经济价值测算——以雅砻江二滩电站为例显示文摘以ArcGIS9.2为平台,构建了基于土地利用/覆被的生态系统供水发电服务物质量和价值量评估模型。包括根据降雨和潜在蒸散发及下垫面特征参数,结合耗水量模拟集水区产出的年供发电水量。由评估水电站的特征参数和集水区每个象元对总供水量的贡献率,采用水能资源公式模拟集水区生态系统发电贡献量的空间分布特征。价值量模型则结合电价及运行成本进行计算。在二滩水电站及其集水区进行了模型的运用。结果表明:2000年,模型模拟为二滩电站贡献汇流的实际供水量达到311.63×108m3.a-1。在水电站设计使用年限内集水区产水总发电量为5763.84×108 kW.H,发电总净利润为888.66×108 Yuan,其中草地生态系统的贡献率最大,达到54.23%。集水区东南部的康定—九龙—冕宁—喜德—西昌一带生态系统供水对于二滩电站发电收益的贡献最大。吴楠 高吉喜 苏德毕力格 Driss Ennaanay Guillermo F.Mendoza 罗遵兰 李岱青 田美荣 2011水力发电学报2011,30,4:2
