AB  - Ferroelectric thin films based on the polymer material
polyvinylidene fluoride (PVDF) can potentially have a wide range
of applications, due to the strong connection between their
electrical, mechanical and thermal properties. PVDF thin films
can be applied in memory devices. The most widespread
application of these elements is in piezoelectric sensors, actuators
and energy harvesters from mechanical vibrations and
mechanical impacts (the so-called "energy harvesting"). A very
important operation in the production and testing of thin PVDF
films is the polarization of the ferroelectric domains in the
material. Similar to the case of ferromagnetic materials, after the
production of the polymer material, the polarization domains in
it are oriented stochastically, so it is necessary to perform their
orientation by direction and course. For this reason, the
ferroelectric sample is exposed to relatively high electric field
strengths of (30÷100) kV/cm in order to orient and direct the
domains. The paper presents the practical realization of the
laboratory experimental setup of the system for high-voltage
polarization of ultra-thin PVDF films by means of a high-voltage
corona. Controlled corona is achieved in a hermetically sealed,
temperature controlled and electrically isolated chamber. Finally,
some key experimental results concerning high-voltage
polarization are given.

AB  - The accumulating evidence on the relation between the disturbed metal homeostasis and epilepsy urges the need for data regarding the total metal concentrations, as well as metal distribution in the brain itself, in order to indicate where to direct the potential therapy, to metal supplementation or chelation. This paper summarizes our results on the measurements of some important essential metals in hippocampi of patients with mesial temporal lobe epilepsy (mTLE) who underwent amigdalohippocampectomy. The key findings point out that levels of copper and manganese are deficient in hippocampi of mTLE patients, and that their concentrations correlated positively with neuronal loss in affected regions of sclerotic hippocampus. In addition, the Cu concentration was decreased in the areas of total neuronal loss. Iron and zinc total hippocampal levels were neither accumulated nor deficient compared to control. Our results contribute to deeper insight of metals biology in the epilepsy and may represent the initial point of new and non-invasive therapy of drug resistant epilepsy.
