| 1 | Visible-light-promoted oxidative coupling of styrene with cyclic ethers显示文摘A new visible-light-promoted oxidative coupling of vinylarenes with cyclic ethers has been developed using rose bengal as photocatalyst and tert-butyl hydrogenperoxide(TBHP)as oxidant under ambient air at room temperature.A library ofα-oxyalkylated ketones with broad functionalities has been synthesized in moderate to good yields.A radical mechanism is suggested for the present protocol. | Golam Kibriya Debashis Ghosh Alakananda Hajra | 2020 | Science China Chemistry2020，63，1： | 4 |

| 10 | Abrupt change of dielectric properties in mullite due to titanium and strontium incorporation by sol-gel method显示文摘Highly crystallized mullite has been achieved at temperatures of 1100℃and 1400℃by sol-gel technique in presence of titanium and strontium ions of different concentrations:G_(0)=0 M,G_(1)=0.002 M,G_(2)=0.01 M,G_(3)=0.02 M,G_(4)=0.1 M,G_(5)=0.2 M and G6=0.5 M.X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),field emission scanning electron microscopy(FESEM),LCR meter characterized the samples.Mullite formation was found to depend on the concentration of the ions.The dielectric properties(dielectric constant,loss tangent and AC conductivity)of the composites have been measured,and their variation with increasing frequency and concentration of the doped metals was investigated.All the experiments were performed at room temperature.The composites showed maximum dielectric constants of 24.42 and 37.6 at 1400℃of 0.01 M concentration for titanium and strontium ions at 2 MHz,respectively.Due to the perfect nature of the doped mullite,it can be used for the fabrication of high charge storing capacitors and also as ceramic capacitors in the pico range. | Biplab Kumar PAUL Kumaresh HALDAR Debasis ROY Biswajoy BAGCHI Alakananda BHATTACHARYA Sukhen DAS | 2014 | Journal of Advanced Ceramics2014，3，4： | 0 |
| 11 | The Influence of Cobalt Acetate on Sol-gel Derived Mullite Densification Behaviour显示文摘Monophasic mullite (3Al2O3?2SiO2) samples doped with 0.002 M, 0.02 M, 0.1 M, 0.15 M and 0.2 M of cobalt were prepared by a sol-gel process. Prepared gels were then dried, grinded, pressed into pellets and sintered at 1 000 °C and 1 300 °C for 4 h. Phase formation and densification behavior has been investigated as a function of the cobalt content and sintering temperature. Mullite densification behavior was analyzed .The density of the sintered ceramics was measured using Archimedes method. CoO and Co related compounds were detected by the analysis for G3, G4 and G5 doping levels. The mullite X-ray diffraction suggests predominant incorporation of Co in the glassy phase, whose quantity increased with the doping level. | Debasis Roy Biswajoy Bagchi Alakananda Bhattacharya Sukhen Das Papiya Nandy | 2012 | Journal of Wuhan University of Technology(Materials Science)2012，27，5： | 0 |
