| 1 | Bismuth Modified Porous Silica Preparation,Characterization and Photocatalytic Activity Evaluation for Degradation of Isoproturon显示文摘Porous silica prepared by using an acrylic emulsion has been impregnated with bismuth ion resulting in Bi_2SiO_5 species containing surface.The as-prepared materials have been characterized by X-ray diffraction spectroscopy (XRD),X-ray photoelectron spectroscopy(XPS),UV-Vis diffuse reflectance spectroscopy(UV-Vis DRS), scanning electron microscopy(SEM),energy dispersive analysis of X-ray(EDAX),transmission electron microscopy(TEM),Fourier transform infrared spectroscopy(FTIR) and N_2 adsorption/desorption techniques. EDAX analysis confirms the penetration of bismuth ions into the framework of silica to form Bi_2SiO_5,which is substantiated by XRD.The UV—Vis DRS shows that the catalysts are optically active and XPS confirms the inclusion of bismuth into the framework of silica.FTIR spectra illustrate the formation of Bi—O—Si linkages in the porous silica framework.SEM and TEM show the spherical morphology,whereas N_2 adsorption/desorption study confirms the porosity of the prepared materials.The photocatalytic activity of the material is evaluated for the degradation of isoproturon herbicide and it is found that the material is active as compared to the commercial P-25 Degussa TiO_2. | Anil Kumar Reddy Police Srinivas Basavaraju Durga Kumari Valluri Subrahmanyam Machiraju | 2013 | Journal of Materials Science & Technology2013，29，7： | 4 |
| 2 | Effect of copper nanoparticles exposure in the physiology of the common carp(Cyprinus carpio):Biochemical,histological and proteomic approaches显示文摘Copper nanoparticles(Cu-NPs)are serious water pollutants but their impact in teleosts performance remains poorly understood.In the present study,we have exposed juvenile carps(Cyprinus carpio),a freshwater teleost edible in India to two different doses(20 and 100 mg/L)of Cu-NPs for seven days.The doses selected were eco-relevant considering the contamination levels of certain water resources.The results indicated that the activity oxidative stress enzymes catalase,superoxide dismutase,and glutathione-S-transferase were significantly increased in the kidney,liver and gills of the treated groups when compared to control.Histological analysis revealed that after exposure,disruption of the secondary lamellae of gills,liver damage with pyknotic nuclei and structural disarray of the kidney occurred.Proteomic analysis of the liver showed down-regulation of several proteins including the ferritin heavy chain,rho guanine nucleotide exchange factor 17-like,cytoglobin-1 and up-regulation of diphosphomevalonate decarboxylase and selenide&water dikinase-1.Taken together,the results of suggest that short-term exposure of juvenile carp to Cu-NPs causes oxidative stress and impart serious deleterious effects in the tissues which may affect fish growth and development. | Yugantak Raj Gupta Durai Sellegounder Monica Kannan Seetharam Deepa Balasubramanian Senthilkumaran Yaraguntappa Basavaraju | 2016 | Aquaculture and Fisheries2016，1，1： | 2 |
| 3 | Glass and Mineral Chemistry of Northern Central Indian Ridge Basalts:Compositional Diversity and Petrogenetic Significance显示文摘The glass and mineral chemistry of basalts examined from the northern central Indian ridge (NCIR) provides an insight into magma genesis around the vicinity of two transform faults: Vityaz (VT) and Vema (VM). The studied mid-ocean ridge basalts (MORBs) from the outer ridge flank (VT area) and a near-ridge seamount (VM area) reveal that they are moderately phyric plagioclase basalts composed of plagioclase (phenocryst [An60-90] and groundmass [An35-79]), olivine (Fo81-88), diopside (Wo45-51, En25-37, Fs14-24), and titanomagnetite (FeOt~63.75 wt% and TiO2~22.69 wt%). The whole-rock composition of these basalts has similar Mg# [mole Mg/mole(Mg+Fe2+)] (VT basalt:~0.56-0.58; VM basalt:~0.57), but differ in their total alkali content (VT basalt:~2.65; VM basalt:~3.24). The bulk composition of the magma was gradually depleted in MgO and enriched in FeOt, TiO2, P2O5, and Na2O with progressive fractionation, the basalts were gradually enriched in Y and Zr and depleted in Ni and Cr. In addition, the ΣREE of magma also increased with fractionation, without any change in the (La/ Yb)N value. Glass from the VM seamount shows more fractionated characters (Mg#: 0.56-0.57) compared to the outer ridge flank lava of the VT area (Mg#: 0.63-0.65). This study concludes that present basalts experienced low-pressure crystallization at a relatively shallow depth. The geochemical changes in the NCIR magmas resulted from fractional crystallization at a shallow depth. As a consequence, spinel was the first mineral to crystallize at a pressure >10 kbar, followed by Fe-rich olivine at <10 kbar pressure. | Dwijesh RAY Ranadip BANERJEE Sridhar D IYER Basavaraju BASAVALINGU Subir MUKHOPADHYAY4 | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 2 |
