title: Mechanical properties of VL E27 steel for shipbuilding –SEM fracture investigation (Charpy test in +20°C)

description: One of the basic divisions of steels used for ship hulls and ocean engineering structures is the division into: normal strength steels, high strength steels and extra high strength steels. The belonging to the group is determined by the mechanical properties of the steel, such as: yield point, ultimate strength and plastic elongation after fracture. The steels in each group are divided into categories, differing in the minimum required breaking energy at a specific temperature, determined in the Charpy test. For applications on a more responsible hull structure or offshore structure, additional steel tests may be required - determination of fracture toughness. In the shipbuilding industry, it is most often CTOD (Crack Tip Opening Displacement) test.
The published data concern testing the fracture toughness of VL E27 steel for shipbuilding, with  nominal thickness of 35 mm. It is the first steel from the group of high strength steels. It is characterized by an early low carbon content, as for hull steels, which is one of the reasons for its high ductility. The average carbon content in the tested material was 0.16%. The scope of the tests carried out so far is: tensile test at + 20 ° C, 0 ° C, -20 ° C, impact test at temperatures: 20 ° C, 0 ° C, -20 ° C, -40 ° C, - 60 ° C and a fracture toughness test at temperatures of 20 ° C, 0 ° C, -20 ° C.
The dataset contains the photographic documentation of SEM (scanning electron microscope) fracture investigation (test temperature 20°C)

title: The topography of as-quenched and heat treated 50(2Bi2O3-V2O5)-50SrB4O7 and 50Bi2VO5.5-50SrB4O7 glasses measured with AFM

description: The topography of as-quenched and heat treated 50(2Bi2O3-V2O5)-50SrB4O7 and 50Bi2VO5.5-50SrB4O7 glasses measured with AFM.
Two samples of compositions: 50(2Bi2O3-V2O5)-50SrB4O7 (1st method) and 50Bi2VO5.5-50SrB4O7 (2nd method) were prepared from appropriate amounts of Bi2O3, V2O5 and preprepared polycrystalline strontium–borate and bismuth vanadate.  SrB4O7 was synthesized via a solid state reaction route that involved heating stoichiometric mixtures of analytical grade SrCO3 and H3BO3 at 1073 K for 12 hours. The Bi2VO5.5 was synthesized from the stoichiometric mixture of initial powders of Bi2O3 and V2O5 which were ball-milled in pure acetone for 6 h at room temperature. The milling was performed in steps of 1 h with rest intervals of 10min. The mixture was heated up to 1020K in air and kept at this temperature for 24 h. The heating and cooling rate was of 50K h-1.
Samples of glass were prepared by the conventional melt quenching technique. The melting was conducted in alumina crucibles at 1373 K for 2 hours. The melt was poured onto a preheated (573 K) brass plate and pressed by another plate to obtain flat circular disks of 1–2 mm thickness and 20–30 mm in diameter.
Two types of samples were studied: as-quenched and heat-treated. Sample prepared by 1st method was partially crystallized by heat treating in air at a temperature of 693 K for 3 hours and then kept the samples in the furnace to cool to room temperature. Full crystallization was conducted at 813 K for samples prepared by both methods. 
The microstructure of all samples was determined by means of atomic force microscopy at their fresh fractures with the use of NT-MDT Ntegra AFM.

title: PULSE and ECG measurement from the hand with standing - hands resting on the device - Man 29 age

description: The data set presents the measurements of the pulse and the ECG signal from the hand made with the use of a proprietary measuring system based on the AD8232 chip, a set of green diode and a phototransistor made on the STM32 microcontroller. Thanks to such a constructed device, it is possible to measure the ECG signal in a non-standard way - from the hand in combination with pulse detection. The results show the ECG signal and the pulse for the concise positioning of the hands and forearms in relation to the body and in relation to the measuring device. With the help of the presented results, it is possible to determine or test the best possible hand layout in order to record data in which individual anatomical features are eliminated as well as possible. Additionally, the integration of two measuring systems illustrates the mutual interaction of two measuring systems.

title: The topography of Bi2VO5.5 ceramics prepared by melt-quenching technique was measured with confocal microscope

description: The topography of Bi2VO5.5 ceramics prepared by melt-quenching technique was measured by confocal microscope. 
Two samples were prepared by the conventional melt quenching technique. First one was prepared from powdered ceramic Bi2VO5.5 (name:BiVas quenched ceramic), and the second one from appropriate amounts of Bi2O3 and V2O5 powders (name: BiVas quenched powders). The melting was conducted in alumina crucibles at 1173 K for few minutes. The melt was poured onto a preheated (573 K) brass plate and pressed by another plate to obtain flat circular disks.
 Additionally, melted samples were heat treated at 650 degC for 1h (BiVas quenched ceramic/powder crystallized).
The topography of the samples was also investigated by Confocal Microscope Olympus OLS 4000 Lext with a CCD camera.
