Spectral Characterization of Tin Dioxide for Gas-Sensing Applications

Alghamdi H., Concepcion B., Baliga S., Misra P., Howard University, US

Thin films and powder samples of tetragonal tin dioxide (SnO2) on UV quartz and silicon wafers, created through radio frequency (RF) sputtering in an oxygen/argon mixed atmosphere, have been prepared and characterized spectroscopically. These thin [...]

Microscopic Identification of Micro-Fractures and Deterioration In Arid Environments Of Pro-Oxidant Polyethylene (PE) Specimens Utilizing State of The Art Thermal and Morphological Experimental Protocols

Al-Salem S.M., Al-Hazza A.A., Al-Rowaih A.A., Al-Dhafeeri A.T., Kuwait Institute for Scientific Research, KW

Pro-oxidant filled polyethylene (PE) specimens in standard and internationally accepted dimensions and size, were exposed to arid natural and accelerated weathering conditions. The American Society for Testing and Materials (ASTM) protocols for weathering were followed, [...]

Synthesis and Characterization of Magnetite Nanoparticles, Activated Carbon and their Composites

Adegoke H.I., Adekola F.A., Abdul Raheem M.N., University of Ilorin, NG

Magnetite nanoparticle (MNP), Fe3O4 was prepared via co-precipitation method, activated carbon was produced from coconut coir pith through chemical activation process. As coconut coir showed maximum weight loss at temperatures lower than 500°C, it was [...]

Characterization of Polymer Nanocomposites with Thermal Analysis and Spectrum techniques

Mena Navarro M.E., Estrada Guerrero R.F., Torres González L.A., Tinajero R., Palafox L., Universidad Iberoamericana Ciudad de Mexico, MX

Polymer nanocomposites have attracted attention in materials science because they exhibit different properties from those of their counterpart polymer microcomposites. An important characteristic is the size of nanoparticles, their effects increase because of their scattering [...]

SEM Characterization of Adipose Tissue Structure

Brimiene V., Skaudzius R., Misevicius M., Brimas E., Brimas G., Brimas E., Brimas G., Kareiva A., Vilnius University, LT

In this work the scanning electron microscopy (SEM) was used for the characterization of adipose tissue samples taken from volunteer obese patients. The adipose tissue was taken from 3 layers of adipose tissue (subcutaneous, preperitoneal [...]

Adsorption of Cd (II) Ions from Aqueous Solution Using Activated Carbon Prepared from Vitellaria paradoxa Shell

Adebayo G.B., Adekola F.A., Jimoh A.A., Alao F.O., Adegoke H.I., University of Ilorin, NG

Activated carbon prepared from vitellaria paradoxa shell using ortho-phosphoric acid as activating agent was used for the removal of Cd (II) ions from aqueous solution. The adsorbent sample was characterized by some physicochemical and spectroscopic [...]
