| 2 | Water-Lubricated Ni-Based Composite(Ni-Al_2O_3,Ni-SiC and Ni-ZrO_2)Thin Film Coatings for Industrial Applications显示文摘In this work,pure nickel and Ni-based nanocomposite coatings(N1-Al_2O_3,Ni-SiC and Ni-ZrO_2) were produced on steel substrate by using pulse electrodeposition technique.The industrial performance tests were conducted to evaluate the wear resistance,corrosion resistance,adhesion strength and wettability behaviour of newly developed coatings.Rolling contact ball-on-disc tribometer was used to assess anti-wear behaviour of these coatings under waterlubricated contacts.The results showed that the wear- and corrosion resistance properties of nickel alumina and Ni-SiC composite coatings significantly improved than that of pure Ni and Ni-ZrO_2 coatings.The adhesion and wettability results of Ni-Al_2O_3 composite showed better performance when compared to the rest of the coatings.The effects of incorporating nanoparticles on the surface microstructure,interface adhesion and distribution of the particles were also investigated.The coatings were characterized by using scanning electron microscopy,X-ray diffraction analysis and 3D white light interferometry.The wear failure behaviour of these coatings was further examined by post-test surface observation under optical microscope. | Rizwan Sarwar Bajwa Zulfiqar Khan Vasilios Bakolas Wolfgang Braun | 2016 | Acta Metallurgica Sinica(English Letters)2016,29,1: | 4 |
| 3 | 基于简易微波方法制备高性能MoS2/石墨烯纳米复合材料用于高效析氢反应(英文)显示文摘用于析氢反应(HER)的低成本、高效能催化剂对于推进基于清洁氢气的能源工业非常重要.二维二硫化钼(MoS2)具有显著的催化性能,因而已被人们广泛深入研究.然而,大多数现有的合成方法耗时、复杂且效率较低.本文通过超快(60秒)微波引发的方法生产MoS2/石墨烯催化剂.石墨烯的高比表面积和导电性为MoS2纳米片的生长提供了有利的导电网络和快速电荷转移动力.文中制备的MoS2/石墨烯纳米复合材料在酸性介质中对HER表现出优异的电催化活性,具有62 mV的低起始电位,高阴极电流和43.3mV/dec的Tafel斜率.除了优异的催化活性外, MoS2/石墨烯还具有较长的循环稳定性,在250 mV的过电位下阴极电流密度高达1000 mA cm^-2.此外, MoS2/石墨烯催化剂在30–120°C范围内具有出色的HER活性和36.51 kJ mol^-1的低活化能,提供了潜在的大批量生产和制备的机会. | Shatila Sarwar Amit Nautiyal Jonathan Cook 袁一斐 李俊豪 Sunil Uprety Reza Shahbazian-Yassar 王瑞刚 Minseo Park Michael J.Bozack 张新宇 | 2020 | Science China Materials2020,63,1: | 4 |
| 4 | 湘西下寒武统牛蹄塘组地球化学特征及其对沉积-构造环境的响应显示文摘为深入探讨湘西地区下寒武统牛蹄塘组黑色岩系沉积-构造环境,对三岔剖面黑色岩系进行了详细采样测试,并重点分析了主量、微量及稀土元素地球化学特征。研究结果表明,牛蹄塘组黑色岩系不仅有机碳含量高,而且相比于北美页岩更富集V、Ni、Cr等微量元素。δ^(13) C_(org)及微量元素判别指标V/(V+Ni)、V/Cr、Ni/Co、δU、Ce/La、Ce_(anom)等特征的变化均反映牛蹄塘组沉积期水体属缺氧还原的浅水环境,且Mo/TOC与U_(EF)-Mo_(EF)协同模式表明沉积区当时为一局限海盆环境。稀土元素(REE)中轻稀土相对重稀土富集,且北美页岩标准化分布模式呈近水平略微左倾状,结合元素比值特征和La/Yb-Ce/Yb、La/Yb-ΣREE图解,牛蹄塘组黑色岩系的母岩以长英质岩石为主,但沉积过程也受到海底热液作用影响。同时,根据δCe、δEu的特征与K_(2)O/Na_(2)O-SiO_(2)图解,认为沉积区在早寒武世为被动大陆边缘构造背景。 | 吴育平 刘成林 龚宏伟 柳永军 Awan Rizwan Sarwar 阳宏 曾晓祥 | 2021 | 地质与勘探2021,57,5: | 4 |
| 5 | Wind-induced hydrodynamic changes impact on sediment resuspension for large, shallow Lake Taihu, China显示文摘The internal sediment release is a key factor controlling eutrophication processes in large,shallow lakes.Sediment resuspension is associated with the wave and current induced shear stress in large,shallow lakes.The current study investigated the wind field impacts on sediment resuspension from the bottom at Meiliang Bay of large,shallow Lake Taihu.The impacts of the wind field on the wave,current,and wave-current combined shear stresses were calculated.The critical wind speed range was 4–6 m/s after which wave and current shear stress started to increase abruptly,and onshore wind directions were found to be mainly responsible for greater shear stress at the bottom of Lake Taihu.A second order polynomial fitting correlation was found between wave(R^2 0.4756)and current(R^2 0.4466)shear stresses with wind speed.Wave shear stress accounted for 92.5% of the total shear stress at Meiliang Bay.The critical wave shear stress and critical total shear stress were 0.13 N/m^2 for sediment resuspension whereas the current shear stress was 0.019 N/m^2 after which suspended sediment concentrations(SSC)increased abruptly.A second order polynomial fitting correlation was found between wave(R^2 0.739),current(R^2 0.6264),and total shear stress(R^2 0.7394)with SSC concentrations at Meiliang Bay of Lake Taihu.The sediment resuspension rate was 120 to 738 g/m^2/d during 4–6 m/s onshore winds while offshore winds contributed ≥ 200 g/m^2/d.The study results reveal the driving mechanism for understanding the role of the wind field in sediment resuspension while considering wind speed and direction as control parameters to define wave and current shear stresses. | Abdul Jalil Yiping Li Ke Zhang Xiaomeng Gao Wencai Wang Hafiz Osama Sarwar Khan Baozhu Pan Salar Ali Kumud Acharya | 2019 | International Journal of Sediment Research2019,34,3: | 4 |

| 8 | Smart-phone,paper-based fluorescent sensor for ultra-low inorganic phosphate detection in environmental samples显示文摘A major goal of environmental agencies today is to conduct point-of-collection monitoring of excess inorganic phosphate(Pi)in environmental water samples for tracking aquatic“dead zones”caused by algae blooms.However,there are no existing commercial devices which have been miniaturized and are suitable for the point-of-need-testing(“PONT”)that is required to fully map a large region,such as the Florida Everglades.To solve this challenge,a reflection-mode fluorescence-sensing apparatus was developed,leveraging an environmentally sensitive fluorophore(MDCC)bound to a bacterial phosphate-binding protein to generate a fluorescent optical signal proportional to the concentration of(Pi)present.The combined end-to-end integrated sensor system had a response time of only 4 s,with minimal effects of common interfering agents and a linear range spanning from 1.1 to 64 ppb.To support easeof-use during PONT,the platform incorporated disposable wax-printed paper strip sample pads and a smartphone camera detection system.Since the EPA threshold is currently 30 ppb to prevent eutrophication,this system serves as a rapid test of whether a region is compliant. | Mehenur Sarwar Jared Leichner Ghinwa MNaja Chen-Zhong Li | 2019 | Microsystems & Nanoengineering2019,5,1: | 3 |
| 9 | Regional Impact of Cyclone Sidr in Bangladesh: A Multi-Sector Analysis显示文摘This research investigates the impact of cyclone Sidr on six regional economic systems of Bangladesh. The study uses secondary data on direct damages and corresponding changes in consumer spending and public/private investment expenditure. It employs input–output modeling and simulates the changes in national and regional output,income, and employment due to cyclone Sidr. Our findings indicate that coastal regions of Bangladesh—Barisal,Chittagong, and Khulna—are more vulnerable to cyclone disaster than are other parts of the country. The cycloneinduced loss of output is highest for Chittagong Division and income and employment losses are greatest in Barisal Division. The most affected sectors are housing services,agriculture, construction, and industrial activities. But sectoral losses vary widely across the regions. This research also finds that the present state of consumer spending and investment expenditure is not great enough to handle cyclone-induced output, income, and employment losses. It argues that investment decisions must consider regional patterns of output, income, and employment losses in different economic sectors to ensure cyclone-resilient development in Bangladesh. | Afsana Haque Sarwar Jahan | 2016 | International Journal of Disaster Risk Science2016,7,3: | 2 |

| 12 | Improvement in the dissolution rate and tableting properties of cefuroxime axetil by melt-granulated dispersion and surface adsorption显示文摘A combination of melt-granulated dispersion and surface adsorption techniques was used to enhance the dissolution and tableting properties of cefuroxime axetil(CA).Gelucire 50/13 was used as the melt-dispersion carrier and Sylysia 350 was used to adsorb the melt dispersion.Solubility studies showed an 8-fold increase in solubility at a ratio of 1:1.5 for CA:Gelucire 50/13.The minimum quantity of Sylysia 350 required to achieve the desired flowability and compressibility was 0.5 parts of Sylysia 350 per unit of Gelucire 50/13.Phase solubility studies showed negative ΔG_(tr)^(0) values for Gelucire 50/13 at various concentrations(2-10%,vv/v),indicating the spontaneous nature of solubilization.FT-IR and DSC spectra exhibited drug-excipient compatibility.Molecular modeling by a computational method employing energy minimization revealed entrapment of CA in Gelucire 50/13.The total potential energy of CA(70.562 keal/mol)was reduced to 33.578 keal/mol after solid dispersion with Gelucire 50/13.P-XRD studies indicated that the presence of Sylysia 350 is less likely to promote the reversion of the amorphous CA to a crystalline state.In vitro dissolution studies demonstrated an improved dissolution rate,and drug release at 15 min(Q_(15min))exhibited a 15-fold improvement.The rapidly dissolving CA tablets showed improved dissolution with improved tableting properties. | Jammula Sruti Chinam Niranjan Patra Suryakanta Swain Kanhu Charan Panigrahi Allupati Premananda Patro Sarwar Beg Subas Chandra Dinda Muddana Eswara Bhanoji Rao | 2013 | Acta Pharmaceutica Sinica B2013,3,2: | 2 |
| 13 | Zinc Application Affects Tissue Zinc Concentration and Seed Yield of Pea(Pisum sativum L.)显示文摘A 2-year field experiment was conducted to assess the effect of applied zinc(Zn) on the seed yield of pea(Pisum sativum L.) and to determine the internal Zn requirement of pea with emphasis on the seed and leaves as index tissues.The experiment was carried out at two different locations(Talagang,Chakwal district and National Agricultural Research Centre(NARC),Islamabad) in the Potohar Plateau,Pakistan by growing three pea cultivars(Green feast,Climax,and Meteor).The soils were fertilized with 0,2,4,8,and 16 kg Zn ha^(-1) along with recommended basal fertilization of nitrogen(N),phosphorus(P),potassium(K),and boron(B).Zinc application increased seed yield significantly for all the three cultivars.Maximum increase in the pea seed yield(2-year mean) was21%and 15%for Green feast,28%and 21%for Climax,and 34%and 26%for Meteor at Talagang and NARC,respectively.In all cultivars,Zn concentrations in leaves and seed increased to varying extents as a result of Zn application.Fertiliser Zn requirement for near-maximum seed yield varied from 3.2 to 5.3 kg ha^(-1) for different cultivars.Zinc concentrations of leaves and seeds appeared to be a good indicator of soil Zn availability.The critical Zn concentration range sufficient for 95%maximum yield(internal Zn requirement)was 42-53 mg kg^(-1) in the pea leaves and 45-60 mg kg^(-1) in the seeds of the three pea cultivars studied. | Ejaz RAFIQUE Munazza YOUSRA Muhammad MAHMOOD-UL-HASSAN Sair SARWAR Tauseef TABASSAM Tayyaba K.CHOUDHARY | 2015 | Pedosphere2015,25,2: | 2 |

| 16 | Utility of liver biopsy in predicting clinical outcomes after percutaneous angioplasty for hepatic venous obstruction in liver transplant patients显示文摘AIM: To determine utility of transplant liver biopsy in evaluating efficacy of percutaneous transluminal angioplasty(PTA) for hepatic venous obstruction(HVOO). METHODS: Adult liver transplant patients treated with PTA for HVOO(2003-2013) at a single institution were reviewed for pre/post-PTA imaging findings, manometry(gradient with right atrium), presence of HVOO on prePTA and post-PTA early and late biopsy(EB and LB, < or > 60 d after PTA), and clinical outcome, defined as good(no clinical issues, non-HVOO-related death) or poor(surgical correction, recurrent HVOO, or HVOOrelated death). RESULTS: Fifteen patients meeting inclusion criteria underwent 21 PTA, 658 ± 1293 d after transplant.In procedures with pre-PTA biopsy(n = 19), no difference was seen between pre-PTA gradient in 13/19 procedures with HVOO on biopsy and 6/19 procedures without HVOO(8 ± 2.4 mm Hg vs 6.8 ± 4.3 mm Hg; P = 0.35). Post-PTA, 10/21 livers had EB(29 ± 21 d) and 9/21 livers had LB(153 ± 81 d). On clinical follow-up(392 ± 773 d), HVOO on LB resulted in poor outcomes and absence of HVOO on LB resulted good outcomes. Patients with HVOO on EB(3/7 good, 4/7 poor) and no HVOO on EB(2/3 good, 1/3 poor) had mixed outcomes. CONCLUSION: Negative liver biopsy greater than 60 d after PTA accurately identifies patients with good clinical outcomes. | Ammar Sarwar Edward Ahn Ian Brennan Olga R Brook Salomao Faintuch Raza Malik Khalid Khwaja Muneeb Ahmed | 2015 | World Journal of Hepatology2015,7,14: | 2 |
