AbstractHere in this study timing saving, easy and cost effective methods has been applied for fabricating the dielectric energy storage materials. Ceramic nanoparticles (FLZC’s) have been successfully synthesized by Sol-Gel method and its nanocomposites with non-conducting polymers (PVP, PVA, PEG, PEO) and multiwalled carbon nanotubes (MWCNT’s) by one-pot blending technique. Energy dispersive x-ray diffraction (EDX), x-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA/DTA), AC impedance analyzer and dielectric properties were determined for all the samples. Dielectric properties showed good agreement with that of energy storage substances for electronic device fabrication. High dielectric constant was achieved when 0.5 wt% MWCNT’s was added to FLZC’s/MWCNT’s/Polymer nanocomposites. The stability and performance of the nanocomposites were dependent on the type of polymer used. These preparation materials can be employed in functional materials, such as high charge-storage capacitors, electrostriction for artificial muscles and smart skins etc.

Here we report a simple in situ template approach for the synthesis of uniformly-shaped straight carbon microtubes (SCMTs) under moderate conditions, in which zinc carbonate powder and glycol were used as starting materials. The morphology and microstructure of SCMTs were characterized by SEM, TEM, HRTEM, XRD and Raman spectrum. The length and diameter of SCMTs can be controlled by simply varying the concentration of zinc carbonate in glycol. Experimental results show that ZnO nanorods generated during the process act as an in situ template for SCMT formation. Owing to their large inner spacing, SCMTs may have potential applications in supporter materials for drugs, dyes, and catalysts, microreactors, and hydrogen or energy storage materials.

Within the framework of the ESRF Phase I Upgrade Programme, a new state-of-the-art synchrotron beamline ID16B has been recently developed for hard X-ray nano-analysis. The construction of ID16B was driven by research areas with major scientific and societal impact such as nanotechnology, earth and environmental sciences, and bio-medical research. Based on a canted undulator source, this long beamline provides hard X-ray nanobeams optimized mainly for spectroscopic applications, including the combination of X-ray fluorescence, X-ray diffraction, X-ray excited optical luminescence, X-ray absorption spectroscopy and 2D/3D X-ray imaging techniques. Its end-station re-uses part of the apparatus of the earlier ID22 beamline, while improving and enlarging the spectroscopic capabilities: for example, the experimental arrangement offers improved lateral spatial resolution (∼50 nm), a larger and more flexible capability forin situexperiments, and monochromatic nanobeams tunable over a wider energy range which now includes the hard X-ray regime (5–70 keV). This paper describes the characteristics of this new facility, short-term technical developments and the first scientific results.
