title: Mechanical properties of VL E27 steel for shipbuilding – impact in test 0°C, 3D model of fracture

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.
Dataset contains fracture documentation - high resolution photography and 3D model (cloud of points) of fracutre. Charpy impact test temperature  0°C.

title: Structural investigations of the LTO:Cu thin films

description: Lithium titanate (Li1+xTi2-xO4) doped with Cu2+ ions was synthesized by sol-gel processing method. The structure was characterized by X-ray Diffraction (XRD). All samples revealed presence of LTO spinel phase. X-ray pattern of undoped LTO was free of any impurities and other crystal phases. Similarly, samples with low amount of copper dopant (x = 0.05 and x = 0.1) exhibit pure LTO spinel phase due to the successful substitution of titanium by copper ions. However, XRD patterns for samples with larger amount of Cu (x = 0.15 and x = 0.2) revealed a mixture of lithium titanate and metal copper oxide. Presence of the Cu metal in samples with high content of copper dopant could be related with inability to substitute a larger number of titanium ions by copper.

title: The radiated immunity test of an astable multivibrator at over-normative field strengths

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 80 MHz to 1 GHz were performed with measurement set up under the requirements specified in the electromagnetic compatibility (EMC) standards. The measurements were executed at over-normative field strengths of 15 V/m, 25 V/m, 35 V/m, 40 V/m, 45 V/m, and 50 V/m, respectively.
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 subjected to the immunity test. 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.  
The normative test procedure was carried out in the frequency range starting at 80 MHz and incrementing in 1% steps up to at least 1 GHz. The RF signal was modulated with a sinusoidal signal with a frequency of 1 kHz and a modulation depth of 80%. The position of the equipment under test (EUT) in the uniform area of the GTEM cell was changed for three orthogonal orientations x, y, z. Based on the results of measurements 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], it was found that the position y (vertical) of the EUT in the GTEM cell is the most susceptible to disturbances. Therefore, immunity tests at higher than standard levels of electric field strength were carried out only in the vertical position of the EUT for the previously selected RF signals.
The attached files contain oscillograms showing the voltage waveforms recorded from the PCB for the electromagnetic field strength equal to 15 V/m, 25 V/m, 35 V/m, 40 V/m, 45 V/m, and 50 V/m, respectively. For each case, information about the RF frequency of the signal generator is included in the file description.  Figure 1.

title: Glutathione conjugation of the antitumor-active 1-nitroacridine derivatives compounds C-857 and C-1748 – the major role of glutathione S-transferase M1-1

description: Objectives: C-857 and C-1748 are antitumor-active agents, monomers of unsymmetrical bisacridine derivatives. The aim of this study was to analyze their glutathione (GSH) conjugation in vitro in the presence of glutathione S-transferase (GST) M1-1.
Methods: 0.01 mg/mL recombinant hGSTM1-1 (expressed in Escherichia coli, obtained from Sigma-Aldrich, MO, USA), 0.01 mM C-857 (C-1748), and 5 mM reduced L-glutathione (GSH) in 0.1 M potassium phosphate buffer solution (pH 6.5) were incubated at 37 °C for 0 and 60 min in a total volume of 50 µL. MgCl2 solution (2 mM) was added for enzyme stimulation. The incubations were terminated by adding ice-cold MeOH to the incubation mixtures (1:1, v/v). The samples were vortexed, placed in ice for 10 min, and centrifuged at 10000 x g for 10 min. Aliquots of the supernatants (50 µL) in triplicate were then analyzed directly by reversed-phase liquid chromatography (RP-LC) with UV-vis detection and/or diode array and multiple wavelength detection, and monitored by MS.
Key findings: Our data demonstrated that both C-857 and C-1748 are extensively metabolized by hGSTM1-1. It was possible to identify one metabolite whose initial structure was identified by LC/MS as a GSH monoconjugate of C-857 (C-1748). GST-mediated GSH conjugation of these compounds may play an important role in their elimination in humans, strongly affecting bioavailability.

title: Electrochemical data for 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.
The electrochemical analyses were performed using a BioLogic VMP-3 potentiostat in a three-electrode setup, with the reactor equipped with a temperature-controlled bath at 25 ℃. A mercury sulfate electrode (MSE, HgǀHg2SO4 in 1 M H2SO4, RE-2CP) served as the reference electrode (RE), while a platinum wire was used as the counter electrode (CE). The working electrode (WE) consisted of a 10 x 40 mm graphitic foil with a thickness of 125 µm (Goodfellow) coated with an active material. The active material dispersion was prepared at a concentration of 10 mg/mL in a solution of isopropanol/water (1:3 by volume) containing 0.05 % Nafion (Sigma-Aldrich) as a binder. The electrodes were fabricated by drop-casting 200 µL of the active material dispersion onto both sides of the graphitic foil, followed by drying at 90 ℃ under vacuum for 12 hours. All electrochemical measurements were conducted under acidic conditions using 0.5M H2SO4. To evaluate the stability of the most active material, current densities of 10, 20, and 50 mA/cm2 were applied for 20 hours. All potentials were referenced to the reversible hydrogen electrode (RHE), calculated using the equation ERHE=0.059 x pH + EWE + E0, where ERHE, EWE, and E0 represent the potential of reversible hydrogen electrode (RHE), working electrode (WE), and standard potential of reference electrode vs. RHE (E0 = 0.657 V), respectively. Before electrochemical testing, the mercury sulfate electrode (MSE) was calibrated in 0.1 M HCl solution relative to the RHE.
