title: Mechanical properties of VL E27 steel for shipbuilding – 3D model of fracture  (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.

title: Raman data of molybdenum diselenide-borophene (B/MoSe2) composite

description: Molybdenum diselenide (MoSe2) and boron powders were purchased from Sigma Aldrich. All reagents were used without further purification.
Both bulk MoSe2 and boron have been introduced to the planetary zirconia ball mill (Fritsch Pulverisette). A series of composites with different MoSe2 to boron ratios MoSe2/B_1:10, MoSe2/B_1:1, MoSe2/B_10:1, MoSe2/B_100:1, and MoSe2/B_1000:1 with a total mass loading of 500 mg have been fabricated. Each of the prepared composites was milled using the same operating parameters with the exact number of zirconia balls (18). These processes were carried out for a total grinding time of 6 hours (to avoid overheating, the processes were conducted in a cyclic manner – 30 minutes of operation with 15-minute breaks), at a rotational speed of 450 rpm. The sample composed by MoSe2/B_1:1 manifested the best electrochemical behavior (it will be labeled as B/MoSe2), thus only this sample underwent detailed analyses.
Raman spectroscopy was conducted using an InVia Renishaw Raman microscope, employing a 532 nm excitation wavelength. Raman spectroscopy was conducted using an InVia Renishaw Raman microscope, employing a 532 nm excitation wavelength.

title: Thermal properties. DSC analysis of poly(xylitol sebacate-co-butylene sebacate) PXBS.

description: In this work, a bio-based copolyester with good mechanical properties was synthesized andcharacterized in terms of structure, main properties and biodegradability Determining the chemicalstructure of such materials is important to understand their behavior and properties. Performingan extraction of insoluble cross-linked polymer using di erent solvents allowed us to analyze howthe polymer behaves when subjected to di erent chemical environments, and to obtain solublesamples suitable for more in-depth analysis. Chemical structure of poly (xylitol sebacate-co-butylenesebacate) was determined by a 1H NMR and FTIR analysis of both prepolymer gel sample andsamples obtained by extraction of cross-linked polymer using di erent solvents. Block structure ofthe copolymer was confirmed by both NMR and DSC. Gel fraction, swelling value, water contactangle, and mechanical properties were also analyzed. Biodegradability of this material was confirmedby performing enzymatic and hydrolytic degradation. Synthesizing sugar-alcohol based copolyesterusing three monomers leads to obtaining a material with interesting chemical structure and desirablemechanical properties comparable to conventional elastomers.

title: The effect of pH change of oxyteracycline solutions on the on inhibition of bioluminescence of Vibrio fischeri (Microtox)

description: In this study attempt was also made to determine whether a pH change of the sample containing oxyteracycline solutions affects the total toxicity of the sample using the Microtox®
As reported by Kudlak B, Wieczerzak M, Yotova G, Tsakovski S, Simeonov V, Namieśnik J (2016) Environmental risk assessment of Polish wastewater treatment plant activity. Chemosphere 160:181-188. https://doi.org/10.1016/j.chemosphere.2016.06.086), environmental water samples (collected from numerous locations in Poland) had pH values ranging from 4.93 to 8.15, with an average value of 7.15 (Kudłak et al. 2016). Therefore, for this purpose, solutions of oxyteracycline were subjected to pH adjustments with concentrated HCl or NaOH. The solutions were adjusted to seven different pH values ranging from 5.5 to 8.5, and the pH was measured with a pH meter.  Subsequently followed the microtox protocol as described in the Wieczerzak M., Kudłak B. an Namieśnik J., (2016)  Study of the effect of residues of pharmaceuticals on the environment on the example of bioassay Microtox®.

title: The radiated immunity test of an astable multivibrator in the frequency range from 100 MHz to 300 MHz

description: The dataset presents a result of measurements that are a part of electromagnetic field immunity tests. The radiated, radio frequency, immunity tests were carried out for a typical astable electronic multivibrator. Tests of immunity of electronic systems to radiated radio frequency (RF) disturbances in the frequency range from 100 MHz to 300 MHz were performed with measurement set up under the requirements specified in the electromagnetic compatibility (EMC) standards. The measurements were executed at a normative field strength of 10 V/m. The signal generator provided three types of RF signals: an unmodulated signal, an 80% AM modulated signal with a modulating frequency of 200 Hz, and a 200 Hz pulse modulated signal.
In laboratory conditions, the electromagnetic fields were simulated in the GTEM (Gigahertz Transverse Electromagnetic) cell (Fig. 1). An integrated signal generator, equipped with a built-in 45 W class A power amplifier module, was used in the measurement setup. The tested multivibrator was supplied from a battery of 9 V. The signal cable connected to the input of an oscilloscope was led out of the tested PCB. The measurement process was controlled by the WIN 6000 software installed on a personal computer connected to the signal generator via the IEEE488 interface.
A typical astable multivibrator was equipment under test (EUT) in the immunity measurements. The proper operation of the device is indicated by flashing LEDs with variable frequency. The system sensitivity to the radiated field in the GTEM cell was assessed based on the observation of the differences in the shape between the signal waveform controlling diode switching and the reference waveform recorded with the signal generator turned off.  
Analyzing the results of standard immunity tests presented in [Ławniczak, P., & Pałczyńska, B. (2021). The standard radiated immunity test of an astable multivibrator at normative field strengths [Data set]. Gdańsk University of Technology. https://doi.org/10.34808/1w2q-xp19], the frequency range from 100 MHz to 300 MHz was selected, in which the shape of the signal waveform from the PCB of the EUT differs most from the reference waveform. The immunity test procedure was carried out in the frequency range starting at 100 MHz and incrementing in 1% steps up to at least 300 MHz. The position of the EUT in the uniform area of the GTEM cell was changed for three orthogonal orientations x, y, z. The attached files contain oscillograms showing the voltage waveforms recorded from the PCB. For each case, information about the RF frequency of the signal generator is included in the file description.  Figure 1.
