Sensor for hydrogen peroxide based on Prussian Blue modified electrode: Improvement of the operational stability
Improvement of the operational stability of amperometric sensors based on Prussian Blue (PB) modified glassy carbon electrodes is presented. The long term performance of the sensors was evaluated by injection of hydrogen ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
PHYSICOCHEMICAL CHARACTERIZATION OF DUALLY-MODIFIED BANANA STARCH.
Among the raw materials used to make biodegradable plastics, starch has high potential; however, it must be modified to improve its film-forming properties. In this study, starch isolated from physiologically immature ...
