Finding the Curie Temperature for Ferromagnetic Materials
(The Physics Teacher, 2007-01) Kizowski, Czesław; Budzik, Sylwia; Cebulski, Józef
The laboratory exercise described in this paper is based on a well-known qualitative demonstration of Curie temperature.1 A long ferromagnetic wire, in the form of a spiral, is attracted to a strong permanent magnet placed near its midpoint (see Fig. 1). The temperature of the wire is increased by passing a current through it. When the temperature reaches the Curie point, the wire becomes paramagnetic and is no longer strongly attracted to the magnet. We have developed this demonstration into a quantitative experiment by providing an accurate way to determine the temperature at which the ferromagnetic-paramagnetic transition occurs.
How electromagnetic fields can influence adult stem cells: positive and negative impacts
(Stem Cell Research & Therapy, 2016-04-18) Maziarz, Aleksandra; Kocan, Beata; Bester, Mariusz; Budzik, Sylwia; Cholewa, Marian; Ochiya, Takahiro; Banas, Agnieszka
The electromagnetic field (EMF) has a great impact on our body. It has been successfully used in physiotherapy for the treatment of bone disorders and osteoarthritis, as well as for cartilage regeneration or pain reduction. Recently, EMFs have also been applied in in vitro experiments on cell/stem cell cultures. Stem cells reside in almost all tissues within the human body, where they exhibit various potential. These cells are of great importance because they control homeostasis, regeneration, and healing. Nevertheless, stem cells when become cancer stem cells, may influence the pathological condition. In this article we review the current knowledge on the effects of EMFs on human adult stem cell biology, such as proliferation, the cell cycle, or differentiation. We present the characteristics of the EMFs used in miscellaneous assays. Most research has so far been performed during osteogenic and chondrogenic differentiation of mesenchymal stem cells. It has been demonstrated that the effects of EMF stimulation depend on the intensity and frequency of the EMF and the time of exposure to it. However, other factors may affect these processes, such as growth factors, reactive oxygen species, and so forth. Exploration of this research area may enhance the development of EMFbased technologies used in medical applications and thereby improve stem cell-based therapy and tissue engineering.
NANOTECHNOLOGY AS A PART OF PHYSICS TEACHING AT SCHOOL
(Concepts of Physics, 2008-01) Budzik, Sylwia; Kizowski, Czesław
The progress in teaching should be in accord with the progress of science, that’s why the subject of teaching must be supplemented by the elements of modern knowledge which permit pupils to understand better what happens around us. The end of XX century is characterised by the rapid development of nanotechnology, which we deal with in this paper.
