Rapid adsorption and simultaneous photocatalytic effect of Ru doped flower like antimony tungstate
No full textRuthenium (Ru) doped antimony tungstate microflowers, prepared through hydrothermal process, have been investigated for simultaneous adsorption and photocatalysis. The pattern of evolution of microflower structures, however, can be tailored by the synthesis period. This change is observed from the field effect scanning electron microscope and transmission electron microscope images. A possible mechanism behind this morphological change has been developed. An argument based on the zeta potential may be responsible for this distinct morphology due to the strong electrostatic interactions. The variation of a particular x-ray diffraction peak corresponding to the plane {012} with variation of Ru doping percentage shows the decrease in crystallinity along the perpendicular direction to this plane. Besides, the optimum Ru doping percentage is evaluated on the basis of photocatalytic efficiency towards methylene blue (MB) degradation under visible light. The highest dye removal efficiency is observed for 2% Ru doped Sb2WO6 (SWO) adsorbing 97% of the MB dye followed by photocatalytic degradation of almost 64% of the remaining dye in 80 min. Furthermore, using different dyes, it is concluded that Ru-SWO showcases high adsorption toward the cationic dyes while it neither adsorbs the anionic dye nor displays photocatalytic degradation
FOURIER TRANSFORM INFRARED SPECTRA OF CLUSTERS TRAPPED IN SOLID Ar
No full textG.R. Burton, C. Xu. C. Arnold, and D. Neumark, J. Chem. Phys. 104, 2757 (1996)Author Institution: Department of Physics and Astronomy, TCUThe structures and vibrational fundamentals of clusters trapped in solid Ar are under investigation using Fourier transform infrared spectroscopy. anions (n = 2-15) were studied earlier by , using anion photoelectron spectroscopy and zero electron kinetic energy spectroscopy. Tentative assignments were made for a fundamental vibration of each of and , although vibrational structure was unresolved for larger clusters. We present vibrational spectra obtained for species produced by laser ablation of pure germanium followed by trapping in an Ar matrix and compare the experimental observations with the predictions of density functional theory calculations

No full textCzymże jest życie bez marzeń? — filmowa twórczość Sanjaya Leeli Bhansaliego
No full textWHAT MEANS LIFE WITHOUT THE DREAMS? — THE FILM WORKS OF SANJAY LEELA BHANSALI The artistic works of Sanjay Leela Bhansali seem typical for the Bollywood cinema, because they are consistently interwoven with its tradition — the director observes the censorship rules, keeps to the binding standards of film visualization, skillfully uses various film genres, casts famous movie stars, wins awards at Indian festivals and fame abroad. However, when watching in chronological order his five movies shot so far — Khamoshi: The Musical 1996, Hum Dil De Chuke Sanam Straight from the Heart, 1999, Devdas 2002, Black 2005, Saawariya Eternal Soulmate, 2007 — one gets an impression that it is not some Bollywood workhorse’s output, but a real movie author’s oeuvre. Since his debut in 1996 Bhansali has been aware of his creative abilities, he has wanted to develop and manifest his individual artistic style, but at the same time he has seemed bound by the Bollywood film industry rules which he has tried to circumvent or bend in an intelligent way. There is even more to that, as there is a growing suspicion that Bhansali, polishing up his own style, intentionally emphasizes and escalates in his works the features of the Bollywood style, displaying his distance and irony. Naïve viewers perceive Bhansali’s films as exceptionally striking masala movies in which they find everything they expect and like. However, for the connoisseurs they become the evidence that no system of production can fully tame and control a talented artist, because — as Goethe claimed — “A true master proves himself when his means are limited.” WHAT MEANS LIFE WITHOUT THE DREAMS? — THE FILM WORKS OF SANJAY LEELA BHANSALI The artistic works of Sanjay Leela Bhansali seem typical for the Bollywood cinema, because they are consistently interwoven with its tradition — the director observes the censorship rules, keeps to the binding standards of film visualization, skillfully uses various film genres, casts famous movie stars, wins awards at Indian festivals and fame abroad.

Thermal Effects on Electrochemical Performance of Copper Oxide Nanoparticles Decorated Amine-Functionalized Graphene Oxide for Ultrahigh Energy Density Supercapacitor with Real-Life Application
No full textThe article describes the synthesis of copper oxide decorated
amine
functionalized graphene oxide (AGO) composites at four different temperatures,
i.e., 50, 85, 120, and 155 °C. The process involves the generation
of AGO by chemical functionalization and using −NH2 groups to anchor Cu2+ ions via coordinate bonds. Reduction
of Cu2+ results in Cu+ on the surface of AGO,
which is confirmed by XRD and TEM. The surface composition and amine
functionalization of nanocomposites were confirmed by XPS and FTIR
analyses. The dielectric measurements display a decrease in dielectric
constant with an increase in frequency, for all nanocomposites, signifying
better capacitive behavior owing to better polarization. AGC85 displays
ultrahigh specific capacitance and energy density values of ∼3890
F/g and 540.71 Wh·kg–1 at 2.0 A/g current density.
Interestingly, after 10000 cycles, AGC85 shows excellent capacitance
retention of about 85.6%. A solid state supercapacitor device was
fabricated with AGC85 (active material), which can supply power for
running an LED bulb for 60 min prior to a few minutes of charging.
The low-temperature synthesized copper nanoparticle intercalated on
amine-functionalized graphene oxide can be scaled up and used in high-performance
supercapacitors for real-life applications in energy systems
