3-D characterization of carbon nanotube-polymer composites using scanning electron microscopy and confocal Raman microscopy

Zhao M.H., Cannara R.J., National Institute of Standards and Technology, US

3D characterization of the dispersion of CNTs in a polymer matrix is a critical step toward understanding and improving the performance of CNT polymer composites. In this study, SEM and confocal Raman microscopy (CRM) were [...]

Nanoparticle Characterization and Analysis of Airborne Titanium Dioxide in Powdered Cosmetics

Cavaliere M.R., Compton S.P., MVA Scientific Consultants, US

In this study, several powdered cosmetic products were purchased and evaluated for the presence of TiO2 nanoparticles first by automated particle sizing using scanning electron microscopy (SEM) with chemical typing by energy dispersive spectroscopy (EDS) [...]

A Cathodoluminescence Study of InGaN/GaN Multiple Quantum Well and N type GaN Structures

Ramos F., Byrnes D., Lu F., Veeco Process Equipment, Inc, US

A systematic study of the V-pits in 4 periods of InGaN/GaN multiple quantum well structure (MQW) and defects in n type GaN is investigated by room temperature cathodoluminescence. These MQWs were fabricated on a sapphire [...]

Surface modification of nanocrystalline LiCoO2 particles with rare earth oxides using polymeric resin process

Nageswara Raoa B., Venkateswarlub M., Satyanarayana N., Pondicherry University, IN

Among the available positive electrode materials, layer structured LiCoO2 is the most preferred one in commercial Li-ion batteries. However, LiCoO2 exhibits a capacity fading at high rates due to its structural instability and reactivity with [...]

Milling Process Control with Dimensional Feedback on a Focused Ion Beam – Scanning Electron Microscope System (FIB-SEM)

Sanabia J.E., Raith USA, Inc., US

In nanofabrication and nanoanalysis, focused ion beam – scanning electron microscope (FIB-SEM) systems are increasingly used for demanding patterning tasks which rely on precise pattern placement and/or dimension control. Easily verifying and correcting for patterning [...]

Electrical conductivity studies of ZnO dispersed PVdF-HFP nanocomposite solid polymer electrolyte for Lithium batteries

Padmaraj O., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Polymer electrolytes are widely used in lithium batteries, since these have better advantages compared to other electrolytes such as low cost, light weight, no leakage, high energy density, improved safety and flexible design. Polymer electrolytes [...]

Synthesis and characterization of carbon nanotubes by catalytic decomposition of acetylene with Fe/Co/MgO, Co/Zn/Al and (C5H7O2)3Mn/Al as catalysts

Dikio E.D., Vaal University of Technology, ZA

We report our studies on the effect of various catalysts in the synthesis of carbon nanomaterials. The as-prepared carbon nanomaterials were characterized by Raman spectroscopy, high resolution transmission electron microscopy and X-ray diffraction. The catalysts [...]

Heavy Metal Removal from Aqueous Solution using Agricultural Waste

Bansala M., Singhb D., Aggarwalc S., Gargd V.K., Giani Zail Singh College of Engineering & Technology, IN

Biosorption has gained important credibility during recent years because of its ecofriendly nature, excellent performance, and low cost domestic technique for remediation even heavily metal loaded waste water. The potential of cheap cellulose containing natural [...]
