| 1 | A Comparative Investigation on the Structural,Optical and Electrical Properties of SiO_2-Fe_3O_4 Core-Shell Nanostructures with Their Single Components显示文摘The SiO_2-Fe_3O_4 core-shell nanostructures were synthesized by sol-gel chemistry.The morphological features of the nanostructures were examined by field emission scanning electron microscopy which revealed the core-shell nature of the nanoparticles.X-ray diffraction studies evidenced the formation of SiO_2-Fe_3O_4 core-shell nanostructures with high degree of homogeneity.The elemental composition of the SiO_2-Fe_3O_4 core-shell nanostructures was determined by energy-dispersive X-ray spectroscopy analysis.Fourier transform infrared spectroscopy showed the Si-O-Fe stretching vibrations.On analysis of the optical properties with UV-Vis spectra and Tauc's plot,it was found that the band gap of SiO_2-Fe_3O_4 core-shell nanostructures diminished to 1.5 eV.Investigation of the electrical properties of the core-shell nanostructures using field-dependent conductivity measurements presented a significant increase in photoconductivity as compared to those of its single components,thereby rendering them as promising candidates for application as photoelectrodes in dye-sensitized solar cells. | Neena Bachan A.Asha W.Jothi Jeyarani D.Arun Kumar J.Merline Shyla | 2015 | Acta Metallurgica Sinica(English Letters)2015，28，11： | 3 |

| 17 | A Comparative Investigation of Dye-Sensitized Titanium Dioxide(TiO_2) Nanorods Grown on Indium Tin Oxide(ITO) Substrates by Direct and Seed-Mediated Hydrothermal Methods显示文摘We report a comparative investigation of the characteristics of modified TiO_2 nanorods grown on conducting indium tin oxide glass(ITO) substrates by two different hydrothermal methods: the direct method by which rutile TiO_2 nanorods were grown directly on plain ITO substrates and the seed-mediated one using which a thin film of anatase TiO_2 seed layer was laid down by spin coating and annealing prior to the growth of TiO_2 nanorods on it. Microstructural analysis of the samples using X-ray diffraction confirmed their rutile nature. The average crystallite size estimated using Scherrer's formula was found to fall in the range of 11–17 nm in both cases. Field emission scanning electron microscopy revealed the nanorod morphologies of a dandelion arrangement in the case of directly grown ones and a proper vertical orientation in the case of the seed-mediated method. UV–Vis spectroscopy analysis of both the samples exhibited redshifts with intense absorption of visible radiation, and the seed-mediated one was found to possess an increased bandgap. The transport nature of the samples was characterized by significant increase in both dark and photocurrents. The results show that the dark and photocurrent values of the directly grown TiO_2 nanorods were greater than those of the seed-mediated ones by *seven and five folds, respectively, and therefore, it could serve as efficient photoelectrodes in dye-sensitized solar cells. | V.Chandrakala J.Annai Joseph Steffy Neena Bachan W.Jothi Jeyarani Tenzin Tenkyong J.Merline Shyla | 2016 | Acta Metallurgica Sinica(English Letters)2016，29，5： | 0 |
| 18 | Prenatal exposure to the fluoride containing psychiatric drug fluoxetine and anti-oxidative alterations in the neonatal rat brain显示文摘Fluoride is a key ingredient of many psychiatric drugs like fluoxetine(Prozac■Fluoxetine■).Pregnant women frequently use this drug as they suffer from depression and anxiety disorders during this period.Fluoxetine is able to reach the fetus through the placenta and passes to the newborn through milk.In the present study,female Wistar rats were treated with 5,10,and 20 mg/L fluoxetine(containing 94% fluorides)from pregnancy day 10 to day 20.After delivery,the levels of the enzymatic antioxidants in the brain of their offspring at postnatal day 2 were measured.The results showed that,in all fluoxetine exposed groups compared with the control group,there was a significant decrease(P<0.01)in the glutathione,catalase,glutathione S-transferases and potassium and a non-significant increase(P>0.05)in the activity of malondialdehyde and creatine kinase.The results suggest that fluoxetine may be a developmental neurotoxicant due to presence of fluoride hence must be used carefully during pregnancy. | RAMESA SHAFI BHAT AMINA EL GEZEERY ABIR BEN BACHAN MONA AWAD ALONAZI LEENA SALEH ALSUHAIBANI AFAF EL-ANSARY | 2019 | BIOCELL2019，43，2： | 0 |
| 19 | Assessment of the usefulness of integrated disease surveillance and response on suspected ebola cases in the Brong Ahafo Region, Ghana显示文摘Background:This study assessed the quality,core and support functions of the integrated disease surveillance and response(IDSR)system relating to 18 suspected cases of Ebola virus disease(EVD)in the Brong Ahafo Region,Ghana.Methods:Data was collected on selected indicators of the surveillance system relating to 18 suspected cases of EVD,from epidemiological week 19 to 45 of 2014.We conducted in-depth interviews with seven medical directors and two district directors of health services,and also reviewed documentation on the implementation of the core,support and quality functions of the IDSR system.We also monitored news in the media and rumours about EVD within the community as well as in health facility surveillance registers.Results:The study identified gaps in the implementation of IDSR relating to 18 suspected cases of EVD.Health staff heavily relied on haemorrhage as the only symptom for detection of suspected EVD cases.Twelve blood samples and a swab of secretions from the mouth of the thirteenth patient(who died)tested negative for EVD using PCR assay in laboratory confirmation.The blood samples of three patients were discarded,as they did not fit the case definition for suspected cases,whilst two refused for their blood samples to be taken.The community-based surveillance(CBS)system has not been given a prominent role in EVD surveillance and response,as demonstrated by CBS volunteers and health staff not receiving any training in these processes.There was intense public interest in EVD in August and September 2014.That interest has since waned for reasons that have to be formally ascertained.Unfounded fear of and anxiety about EVD still remain challenges due to a lack of in-depth knowledge about the disease in Ghana.Conclusion:Ghana has been one of the pioneers in the implementation of IDSR in Africa.Despite this,gaps have been identified in the implementation of IDSR relating to EVD in the Brong Ahafo Region.To address these gaps,the CBS system has to actively partner with health facility surveillance to achieve effective IDSR in the region. | Kofi Issah Kennedy Nartey Richard Amoah Emmanuel George Bachan Jacob Aleeba Enuamah Yeetey Timothy Letsa | 2015 | Infectious Diseases of Poverty2015，4，1： | 0 |
