| 1 | Rapid Biosynthesis of Silver Nanoparticles Using Cymbopogan Citratus (Lemongrass) and its Antimicrobial Activity显示文摘The present study deals with the rapid green synthesis of silver nanoparticles using fresh leaves of Cymbopogan Citratus(Lemongrass). Silver nanoparticles were formed within 8~10 minutes by microwave irradiation using aqueous solution of Ag NO3(1 m M) with fresh leaves extract of Cymbopogan Citratus. The synthesized silver nanoparticles were characterized by using UV-visible spectrophotometer analysis, nanoparticle tracking analyzer, transmission electron microscope and energy dispersive X-ray spectra. The antibacterial activity of these nanoparticles was studied against multiple drug resistant hospital isolates of E.coli, S.aureus,P.mirabilis and hospital isolates of S. typhi, K.pnuemoniae. Also, the antifungal activity of these nanoparticles was studied against C.albicans(hospital isolate) and A.niger(NCIM 616). The synergistic effect of silver nanoparticles along with antibiotics was also studied against multiple drug resistant hospital isolates and found to be effective. The extracellular synthesis of Silver nanoparticles using leaves of Cymbopogan Citratus appears to be rapid and eco-friendly. | Shalaka A.Masurkar Pratik R.Chaudhari Vrishali B.Shidore Suresh P.Kamble | 2011 | Nano-Micro Letters2011，3，3： | 4 |
| 2 | Effect of Biosynthesized Silver Nanoparticles on Staphylococcus aureus Biofilm Quenching and Prevention of Biofilm Formation显示文摘The development of green experimental processes for the synthesis of nanoparticles is a need in the field of nanotechnology. The synthesis of silver nanoparticles was achieved using Bacillus cereus supernatant and1 m M silver nitrate. 100 m M glucose was found to quicken the rate of reaction of silver nanoparticles synthesis.UV-visible spectrophotometric analysis was carried out to assess the synthesis of silver nanoparticles. The synthesized silver nanoparticles were further characterized by using Nanoparticle Tracking Analyzer(NTA),Transmission Electron Microscope and Energy Dispersive X-ray spectra. These silver nanoparticles showed enhanced quorum quenching activity against Staphylococcus aureus biofilm and prevention of biofilm formation which can be seen under inverted microscope(40 X). The synergistic effect of silver nanoparticles along with antibiotics in biofilm quenching was found to be effective. In the near future, silver nanoparticles could be used in the treatment of infections caused by highly antibiotic resistant biofilm. | Pratik R.Chaudhari Shalaka A.Masurkar Vrishali B.Shidore Suresh P.Kamble | 2012 | Nano-Micro Letters2012，4，1： | 2 |
| 3 | 变形机参数对PET变形丝性能的影响显示文摘聚酯纤维的结构性能优异,应用范围广泛。其性能主要取决于纱线类型、纤维根数、线密度和形状等。受加工过程中热箱温度和D/Y比的影响,这些工艺参数决定了纤维的变形程度。选用27.8 tex/48 F的预取向丝作为基础原料,在拉伸变形机上按标准和调整后的参数进行变形加工处理。通过系列试验研究了变形机参数对纤维线密度、强度和细丝断裂-紧点的影响。研究发现,加捻和解捻的巨大差异导致紧点数量增加;此外,随着热箱温度升高,纤维强度和卷曲收缩率增加,沸水收缩率则降低。 | R.Turukmane S.Patil R.Chaudhari 陈晶晶(译) 于俊荣(校) | 2022 | 国际纺织导报2022，50，2： | 0 |
