SECM Investigation on the Effect of ZnO Nanoparticles on Nasopharyngeal Cancer Cell Respiration
In recent years, there is an overwhelming interest in using nanoparticle for cancer therapy. Many reports show selective cytotoxicity of nanoparticles over cancer cells. However, the mechanism of such behavior is yet to be discovered. [...]
Eddy Current and Microwave Characterization of Fe- Based Alloy Synthesized by Mechanical Alloying
In the present study mechanical alloying has been used to obtain bulk nanocrystalline FeAl intermetallic compound. Nanocrystalline powder of Fe(Al) solid solution was the product of ball milling. The structural effects of mechanical alloying of [...]
Characterization of RF-sputtered ultra-thin WO3 films grown on TiO2 surface
We report on TiO2 and WO3/TiO2 bilayers thin films grown on amorphous and crystalline substrates, at room temperature by plasma-assisted sputtering. TiO2/WO3 ceramic targets were used in an RF magnetron discharge running in an Ar [...]
Design and characteristics of an optical nanosensor based on immobilization of MWCNTs-g-PCA-Au on a triacetylcellulose membrane for determination trace amounts of thiourea
Sarlak N., Sameri Z., Meyer T.J., Shaabani K., Pourrahim R., University of North Carolina at Chapel Hill, US
The characterization of an optical absorption based one-shot sensor is described for the determination of thiourea based on the immobilization of new nanocomposite of MWCNT-graft-poly(citric acid)/Au on a triacetylcellulose membrane. So Multiwalled carbon nanotubes were [...]
Super-hydrophobic paper influence on bacterial attachment suggests potential application as packaging material
Jain S., Li L., Breedveld V., Hess D.W., Barnett C., Davis M., Singh S., Pillai S., Alabama State University, US
The surface topography and chemistry of cellulose-based paper, was controlled by a two-step plasma (glow discharge) treatment. Selective plasma etching of the amorphous regions of cellulose followed by plasma deposition of a thin (100 nm) [...]
Parametric Study on the Effect of Radiation Heat Loss and Non-Constant Heating in the Electrothermal Technique for Thermal Property Measurement of Micro/Nanoscale Fibers
This paper presents a parametric study of the effects of radiation heat loss and non-constant heating on the measurement accuracy of thermal properties of micro/nanoscale fibers using the Transient Electrothermal technique. In the original derivation, [...]
Characterizing Thermal Diffusivity of Synthetic Spider Silk using Improved Transient Electrothermal Technique
This paper presents results for the thermal diffusivity of a synthetically produced spider silk. This synthetic spider silk is being developed for lightweight thermal management applications. Additionally, an improved method for measurement of the thermal [...]
Well trap structures and bulk-nano environment luminescence centers in CaZnGe2O6:Tb3+ long afterglow phosphor
A long afterglow phosphor CaZnGe2O6:Tb3+ has been prepared by using organic coated luminescence ZnO nanopowder through a high temperature solid-state reaction route. This new CaZnGe2O6:Tb3+ long afterglow phosphor sample emits the Tb3+ green fluorescence 543 [...]
