Comparative HRTEM Examination of Carbon Black and Soot Structures

Spry J.M., Compton S.P., MVA Scientific Consultants, US

Soot is a major source of airborne particulate and typically contains primary particles which are less than one micrometer in diameter. Soot particles form as an undesired combustion by-product originating from a variety of different [...]

Magnetic exchange bias effect in Manganese Oxide Core-Shell Nanoparticles fabricated by inert gas condensation technique

Khan F.A., Bah M., Shah S.I., Department of Physics, Bangladesh University of Engineering and Technology(BUET), BD

Manganese oxide core-shell nanoparticles are fabricated by inert gas condensation technique. The as deposited samples are found to be amorphous in nature with random distribution of clustered particles. X-Ray Diffraction (XRD) and High Resolution Transmission [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]

The Effect of Growth Temperature on Aluminum Nanocrystal Embedded AlOxNy for Non-Volatile Memory

Chen N.H., Hsieh P-H, Huang F.S., Huang S-J, Huang F.S., Huang S-J, National Tsing Hua University, TW

The aim of this paper is to present a aluminum-based nonvolatile memory of Al2O3 (28 nm)/ Al-rich Al0.54O0.42N0.04 (22 nm)/ Al0.44O0.38N0.18 (3 nm) layered structure on SiO2 (2 nm)/ n-Si by a simple rapid thermal [...]

Comprehensive Microscopy Analysis of Au/Ag Nanoclusters on Silica Nanospheres

Qian H., Shen W., Cui K., Cho J., Fenniri H., National Institute for Nanotechnology, CA

we report a comprehensive structural and morphological analysis of gold (Au) / silver (Ag) nanocluster (shell) on silica (SiO2) nanosphere (core) with transmission electron microscopy (TEM) based techniques, including scanning transmission electron microscopy (STEM) tomography, [...]

Microwave assisted synthesis of CaO nanoparticles and use in waste water treatment

Roy A., Bhattacharya J., Indian Institute of Technology, Kharagpur, IN

Clean water (i.e., water that is free of toxic chemicals and pathogens) is essential to human health. Advances in nanoscale science and engineering are providing unprecedented opportunities to develop more cost effective and environmentally acceptable [...]
