The characterization of novel solder alloys in terms of their melting properties and wetting behaviour on Cu substrate is an important area of applied research. In Miskolc, the theoretical background is provided by the Department of Nanomaterials of Bay Zoltán Nonprofit Ltd. for Applied Research (Managing Director: Tamás Skultéty, Contact Person: György Kaptay, Prof. Dr.). Based on the results of previous R&D tasks, substantial experience on the brazing of steel joints by Ni- and Cu-based filler metals is also available at BAY-LOGI. Other related research areas cover the thermodynamic properties/behaviour of different alloy systems and the modelling of multicomponent phase equilibria using the Calphad method.
The Department of Nanomaterials of Bay Zoltán Nonprofit Ltd. for Applied Research is conducting research on macro- micro- and nano-level particles, colloid systems and nanocomposites since 2006. By combining the two basic disciplines of Materials Science (chemistry and metallurgy) and adopting a nanotechnological approach, the Department takes an unique position in national and international level R&D. They are involved in fundamental and targeted basic research activities as well as in applied research projects. They act as expert consultants, offering services to research centres, R&D companies and market enterprises. They play a decisive role in education, conducting sub-courses on nanotechnology at BSc, MSc and PhD levels, in close cooperation with the Faculty of Materials Science and Engineering of the University of Miskolc. The productivity of the Department is well reflected in the remarkable number of publications in leading scientific and technical journals, international journals and conference proceedings, where the results are disclosed in compact, concise presentations.
Several innovative technical solutions developed by the Department to industry-related problems are either subjects to patent application or being under effective protection. Over the past decade, both the research infrastructure and the technical know-how has been progressively upgraded by the Department of Materials Testing. The advanced, non-destructive testing of various joining technologies (brazing, welding, adhesive bonding etc.) has attracted considerable attention from industrial partners. Customer-specific requests, in turn, have contributed to a deeper understanding of material processes.
The current project aims involve the refunctionalization of the testing apparatus and the special use of mechanical testing methods (static-, fatigue- and fracture tests) to analyse & evaluate solder bond formation and/or characterize the strenght properties of solder bonds. New results from the mechanical and metallographic examinations can contribute to the practical expertise of the research personnel and boost the number of publications.
As the name suggests, the Institute of Nuclear Research of the Hungarian Academy of Sciences (ATOMKI) (Director: Zsolt Fülöp, Dr.; Contact person: József Hakl, Dr.) is an academic institute for physical and nuclear research, with a personnel of about 190 members (100 of which are active researchers). The primary activity of the Institute is devoted to both experimental and theoretical research in nuclear physics and related fields, covering a broad range of disciplines. Their investigations not only address the problems of modern atomic and subatomic physics, but extend to materials sciences and several other areas that employ the techniques of applied physics research such as environmental and biomedical sciences, geochronology or archaeology. The wide spectrum of multidisciplinary studies has gradually grown out from the first charged-particle accelerators and the associated analytical facilities.
ATOMKI is a member institution of the Hungarian Academy of Sciences. Ever since its foundation, the Institute has been substantially contributing to physics education at the University of Debrecen (UD). At present, up to 40 undergraduate courses are delivered and a number of BSc and MSc theses are suprvised by the research professors. The training of junior scientists at the postgradual level – embedded in a full system of support from undergraduate to habilitation level – forms an essential part of the Atomki’s profile. Besides, the Institute is pursuing outreach activities, targeting secondary-school pupils, university students and the general public with colourful programmes throughout the year. The central programme is the ”Physicists’ Week” dedicated to the large-scale promotion and dissemination of natural sciences.
ATOMKI is a lot more than a regional centre of modern scientific research, development and innovation. The activity of the research groups are deeply integrated in that of the top international collaboration networks in atomic sciences (among them CERN). The research infrastructure of Atomki provides a firm base for fundamental and applied experimental work. Some of its attractive research facilities are notably popular among external users and collaborators. The Institute typically takes part in multilateral international programmes, inter-governmental and inter-academic bilateral programmes, established industrial collaborations and project partnerships as well as ad hoc and informal cooperation agreements with research institutions worldwide.
The research faculties are run via a structured system of laboratories – which make up 20% of the national research infrastructure and are registered as of strategic importance. The Atomki Accelerator Centre (ACC) incorporates several low-energy charged-particle accelerators, laying the base for a variety of projects (from astrophysics to medical and environmental studies). The Atomki’s experience in surface physics and nuclear theory is internationally renowned. With the available devices, a complete quantitative surface analysis of industrial materials can be performed with high depth resolution or high lateral distribution, allowing for the determination of elemental composition and the chemical state of elements as a function of their structural position.
Fundamental research is concentrated on the structure of atomic nuclei (from experimental investigations of basic charge-transfer mechanisms and collision processes to numerical calculations on quantum mechanics). The 3D imaging of surface chemical processes, ion beam analysis, the use of electron spectroscopy for chemical analysis are among the diverse applications of atomic and solid state physics to surface science. Related measurements include the particle-induced inonization/excitation of atoms embedded in solid surface/intersurface layers, electromagnetic and optical measurements, the analysis of surface atomic migration through thin film interfaces.
The R&D&I activities of the Atomki has so far covered corrosion studies on special stainless steel surfaces (mainly used in nuclear plants and atomic reactors), the surface analysis of metals and insulation materials, the depth profile analysis of thin layers or the investigation of glass surfaces and solar modules. In order to keep pace with rapidly evolving science, the Institute strives to systematically extend its knowledge and expertise, and conduct thorough investigations in an ever-growing range of research-related problems and applications.
