In this paper, a simulation model is proposed to describe H2O adsorption-induced curvature of a nanocantilever, based on the energy transfer between potential energy of adsorbates and elastic energy of the bending cantilever. For most cantilever sensors, the basic structure is a silicon beam coated with a metal layer on the top, and aluminum is chosen in this paper. Because the native oxide is usually...
This paper has researched on the adsorption of Ni in water using Laminaria japonica and Undaria pinnatifida. The dependence on pH and nickel concentration of the adsorption was studied. Batch experiments results showed that the adsorptive capacity of Laminaria japonica and Undaria pinnatifida was 2.933mg/g and 0.985 mg/g of adsorbent. The Langmuir model was used to describe the adsorption equilibrium...
Adsorption is an efficient treatment process for the phosphate removal. In this study, cetyl trimethylammonium bromide modified bentonite (CTMAB-Bent) were prepared, characterized, and its adsorption properties for phosphate were evaluated in batch experiments. The results showed that the ability of phosphate adsorption by CTMAB-Bent was far more than that of Na-bentonite and raw bentonite. The process...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
