- Applied Research and Development Project: Nr. APVV-0062-11 (2012 – 2015)

Project title: Pokročilé materiály a štruktúry pre elektrotechniku, elektroniku a biomedicínske aplikácie na báze feritov s rozmermi častíc v oblasti mikrometrov a nanometrov

Principal investigator: doc. Ing. Elemír Ušák, PhD.

Abstract:

The project is aimed at the improvement of the properties of currently very progressive magnetic materials based on ferrites (e.g. Ba hexagonal ferrites, spinel NiZn and Li ferrites, etc.); with approppriate substitution of the ions of chemical elements determining the basic chemical composition with other ions, it is possible to prepare materials with properties tailored for use in new and unconventional applications.

An essential part of the project will be the experimantal determination of the impact of chemical composition, internal structure and preparation technology of the materials having the form of powders with particle sizes in the submicron and nanometer scale as well as more complex structure containing these powder materials (such as e.g. composites), the resulting magnetic structure and electromagnetic properties at various operating conditions, such as defined electromagnetic fields, high pressures, low temperatures, etc.

Achievments and prepared samples can be used to develop new systems with unique properties, which are expected in miniature active and passive electronic components, recording media, micrelectromechanical systems (MEMS), microactuators, microsensors and other microsystems. Another important potential usage of powder materials is their application in biomedicine, namely the trgeted distribution of drugs.

Scientific goals of the project:

Improving the preparation technology of the materials based on ferrites (e.g. Ba hexagonal ferrites, spinel NiZn and Li ferrites, etc.) with the properties optimised for use in new, unconventional applications.

Experimental determination of the impact of chemistry and preparation technology of powdermaterials as well as more complex structures containing these materials (e.g. composites) on the resulting magnetic structure and electromagnetic properties at various operating conditions.

 

- Applied Research and Development Project: Nr. APVV-0333-11 (2012 – 2015)

Project title: Electromagnetic compatibility of technological equipment in tyre industry

Principal investigator: doc. Ing. Mikuláš Bittera, PhD.

Co-investigators : Konštrukta-Industry, a.s. Trenčín; Faculty of Electrical Engineering and Informatics TU Košice

Abstract:

The project deals with innovation of technological equipment used in the tyre industry in term of EMC properties, that may increate the usability, utility valu and also the competitiveness of the equipment developed and designed in Slovakia, which is reflected particularly at international level. The projecy involves identifying sources of interference, their analysis in terms of behavior in the electromagnetic environment and suppression  of their negative effects. Also parts of equipment will be identifies which are sensitive to electromagnetic interference and other task within the project realization is to ensure their failure-free operation. During the analysis risk subsystems will be replaced by the numerical models, thus achieving some degree of prediction of their behavior in an electromagnetic environment. The project will create methodology of technological equipment design with regard to the latest knowledge of EMC area, and thus easier to obtain the CE mark in the future.

Scientific goals of the project:

Based on the EMC standards requirements we will define the characteristics of individual components of the device in terms of EMC. Then we will incorporate EMC design principles to design methodology of technical subsystem as well as of entire system including its large external cabling. We will create an executing sample of the equipment and verify the correctness of realized procedures (to verify unwanted emissions from the equipment and its sensitivity to ambient noise).
