| 1 | Emulsification of Indian heavy crude oil using a novel surfactant for pipeline transportation显示文摘The most economical way to overcome flow assurance problems associated with transportation of heavy crude oil through offshore pipelines is by emulsifying it with water in the presence of a suitable surfactant.In this research,a novel surfactant,tri-triethanolamine monosunflower ester,was synthesized in the laboratory by extracting fatty acids present in sunflower(Helianthus annuus)oil.Synthesized surfactant was used to prepare oil-in-water emulsions of a heavy crude oil from the western oil field of India.After emulsification,a dramatic decrease in pour point as well as viscosity was observed.All the prepared emulsions were found to be flowing even at 1°C.The emulsion developed with 60%oil content and 2wt%surfactant showed a decrease in viscosity of 96%.The stability of the emulsion was investigated at different temperatures,and it was found to be highly stable.The effectiveness of surfactant in emulsifying the heavy oil in water was investigated by measuring the equilibrium interfacial tension(IFT)between the crude oil(diluted)and the aqueous phase along with zeta potential of emulsions.2wt%surfactant decreased IFT by almost nine times that of no surfactant.These results suggested that the synthesized surfactant may be used to prepare a stable oil-in-water emulsion for its transportation through offshore pipelines efficiently. | Shailesh Kumar Vikas Mahto | 2017 | Petroleum Science2017，14，2： | 5 |
| 2 | Potential groundwater recharge zones within New Zealand显示文摘Water resources in New Zealand are not evenly distributed across the country which makes it difficult to adequately allocate the use of water resources in every basin. Groundwater is a fundamental water resource in New Zealand for agricultural, industrial and domestic use. Detailed knowledge regarding groundwater recharge potential is a pre-requisite for sustainable groundwater management, including the assessment of its vulnerability to contamination by pollutants. In this study, a comprehensive GIS approach was used to map the potential groundwater recharge zones across New Zealand. National data sets of lithology, slope, aspect, land use, soil drainage and drainage density were converted to raster data sets with a spatial resolution of 500 m x 500 m and superimposed to derive groundwater potential zones. The resultant maps demonstrate that the potential is low in urban and mountainous areas, such as the Southern Alps, whereas the highest potential can be found in regions with large lakes and in the lower elevation plains areas, where Quaternary sediments prevail. The resulting maps can be used to identify areas of high nutrient leaching in zones where high groundwater recharge potential exists. | Shailesh Kumar Singh Malte Zeddies Ude Shankar George A.Griffiths | 2019 | Geoscience Frontiers2019，10，3： | 3 |

| 13 | Sorghum germplasm from West and Gentral Africa maintained in the ICRISAT genebank: Status,gaps,and diversity显示文摘The genebank at ICRISAT maintains 8020 accessions of sorghum from 16 West and Central African countries. Geographical gaps and diversity were assessed in the collection. Using the passport data of 3991 accessions for which georeferenced data were available, a total of386 districts(gaps) located in 11 West and Central African countries were identified as geographical gaps. Burkina Faso with 140 and Nigeria with 118 districts were identified as countries with major geographical gaps. The collection of 43 accessions of wild species represented only three species belonging to Sorghum bicolor ssp. drummondii and ssp.verticilliflorum, S. hevisonii, and S. macrochaeta, highlighting the need for collection missions aimed exclusively at enriching the collection of wild relatives. Accessions having characterization data(7630) were used to assess diversity. The first three principal components contributed to >60% of variation. Maximum diversity was observed in the collection from Nigeria for both qualitative and quantitative traits. Mean values indicated significant differences between basic and intermediate races for the traits studied. Among the races, accessions of guinea-caudatum for qualitative traits and those of caudatum for quantitative traits were highly diverse. The low intensity of the sorghum collection and the many geographical gaps in the collection underline the importance of launching collection missions to fill the gaps, particularly in regions of predominantly guinea sorghums.Genotyping of possible duplicate accessions is needed to identify duplicates in the collection. It is suggested that all passport information including georeferenced data of collection sites should be collected when samples are collected in gaps. | Hari Deo Upadhyaya Kothapally Narsimha Reddy Mani Vetriventhan Mohammed Irshad Ahmed Gumma Murali Krishna Mulinti Thimma Reddy Shailesh Kumar Singh | 2017 | The Crop Journal2017，5，6： | 0 |

| 15 | On-chip excitation of single germanium vacancies in nanodiamonds embedded in plasmonic waveguides显示文摘Monolithic integration of quantum emitters in nanoscale plasmonic circuitry requires low-loss plasmonic configurations capable of confining light well below the diffraction limit.We demonstrated on-chip remote excitation of nanodiamond-embedded single quantum emitters by plasmonic modes of dielectric ridges atop colloidal silver crystals.The nanodiamonds were produced to incorporate single germanium-vacancy(GeV)centres,providing bright,spectrally narrow and stable single-photon sources suitable for highly integrated circuits.Using electron-beam lithography with hydrogen silsesquioxane(HSQ)resist,dielectric-loaded surface plasmon polariton waveguides(DLSPPWs)were fabricated on single crystalline silver plates to contain those of deposited nanodiamonds that are found to feature appropriate single GeV centres.The low-loss plasmonic configuration enabled the 532-nm pump laser light to propagate on-chip in the DLSPPW and reach to an embedded nanodiamond where a single GeV centre was incorporated.The remote GeV emitter was thereby excited and coupled to spatially confined DLSPPW modes with an outstanding figure-of-merit of 180 due to a~six-fold Purcell enhancement,~56%coupling efficiency and~33μm transmission length,thereby opening new avenues for the implementation of nanoscale functional quantum devices. | Hamidreza Siampour Shailesh Kumar Valery A.Davydov Liudmila F.Kulikova Viatcheslav N.Agafonov Sergey I.Bozhevolnyi | 2018 | Light(Science & Applications)2018，7，1： | 0 |
| 16 | 药用金钮扣属植物研究综述(英文)显示文摘植物药在人类的医学实践中已有上千年的应用历史,特别是在亚洲的一些国家,植物药用资源被认为是一种可以随时取用的宝贵的医疗保健资源。印度拥有众多种类的药用植物,然而,其中很大一部分传统药用植物并没有被开发使用或未被现代医学科学研究证明其功效。因此,目前很有必要开发传统药用植物并使其最大限度地造福人类。本篇综述总结报道了一种很有潜力的药用植物即金钮扣属植物。过去几年中,很多从这类植物中提取的新化合物及其功效已经得到证实,因此本文旨在总结最新的有关金钮扣属植物的植物化学及民族药物学应用、药理学作用及物种保护方法的科学研究报道。 | Kishan Lal Tiwari Shailesh Kumar Jadhav Veenu Joshi | 2011 | 中西医结合学报2011，9，11： | 0 |
