The synthesis of magnetic Cu1-xNix nanoparticles was carried out in cationic water-in-oil (w/o) microemulsions of water/cetyl-trimethyl-ammonium bromide (CTAB), n-butanol/isooctane by the reduction of nickel and copper chlorides with hydrazine and NaOH. The synthesized Cu1-xNix particles were heat treated to maintain their proper homogeneity and Curie temperature. Some alloy particles with the composition Cu27.5Ni72.5 were coated with silica prior to the thermal homogenization in order to retain the pristine morphology. The magnetic particles were characterized using XRD, transmission electron microscopy (TEM) and magnetic measurements. The thermal demagnetization in the vicinity of the Curie temperature of the nanoparticles was studied using a modified TGA/SDTA method. [ABSTRACT FROM PUBLISHER]

In this work the development and deployment of a new concept of cartoon-generation on a mobile phone is presented. An interactive multimedia application was designed for a push-approach of sending short e-cartoons from a mobile phone to a central WEB server. The concept of a unique cartoon-generator will be discussed. The multimedia Authoring Environment Flash was used for the interactive application design and implementation. The architecture and the design process of the interactive cartoon-generator application will be presented including storyboarding with final testing of the application on a Nokia mobile phone.
