QUARTZ CRYSTAL MICROBALANCE: NANO-SENSOR FOR CYANIDE DETECTION
Journal Title: Journal of Science And Arts - Year 2012, Vol 19, Issue 2
Abstract
The extremely high level of potassium cyanide toxicity makes its effects to be important even in low concentrations. Quartz crystal microbalance (QCM) allows the determination of these values due to the high sensitivity of resonant crystal frequency. The sensitivity of the method increases with the alkaline pH values and for this reason in this study it has used two sets of solutions with pH 9 and 12. The obtained experimental results lead to the conclusion that the QCM method can be successfully used to obtain an accurate quantitative and qualitative analysis of cyanides in drinking water in real time.

BASIC CONCEPTS ON MAGNETIZATION REVERSAL IN NANOSTRUCTURES: MAGNETIC FIELD AND TEMPERATURE INFLUENCE
In this lecture, we will address the problem of magnetization reversal in thin films and nanostructures. This topic is at the basis of most studies in the fields of magnetism and spintronics and is of particular relevanc...
TIMELIKE BIHARMONIC S-CURVES ACCORDING TO SABBAN FRAME IN (S1^2)H
In this paper, we study timelike biharmonic curves according to Sabban frame in the (S1^2)H. We characterize the timelike biharmonic curves in terms of their geodesic curvature. Finally, we find out their explicit parame...
