Material properties of CFRP composite
No full textW pliku przedstawiono informacje dotyczące określenia właściwości materiałowych dla materiału kompozytowego CFRP wykorzystanego do badań. Wyznaczono właściwości materiałowe dla różnych temperatur. Dane przedstawiono w formie tabelarycznej i w formie wykresów. Dane dotyczą materiału kompozytowego wyprodukowanego na potrzeby projektu NCN (OPUS) nr 2022/47/B/ST8/00600, którego celem jest analiza stateczności i stanów pokrytycznych ściskanych elementów kompozytowych o różnych kształtach przekroju poprzecznego, wykonanych z kompozytów włóknistych w układzie niesymetrycznym, a także zbadanie wpływu sprzężeń mechanicznych na zachowanie tego typu struktur w stanie krytycznym, pokrytycznym i w fazie zniszczenia.The file presents information on determining the material properties of the CFRP composite material used for the tests. The material properties were determined for different temperatures. The data are presented in tabular and graph form. The data concern the composite material produced for the NCN (OPUS) project no. 2022/47/B/ST8/00600, the purpose of which is to examine the stability and post-critical states of compressed thin-walled composite structures with complex cross-sections, made of fibrous composites in asymmetrical layouts of composite layers, and to investigate the effect of mechanical couplings in the critical, post-critical states and in the phase of failure.</p

Bioactive Copper-Doped Natural Hydroxyapatite Quantum Dots/Graphene Oxide Nanocomposites in 3D-Printed PCL Scaffolds for Superior Osteogenic and Angiogenic Performance in Bone Tissue Engineering
No full textThis study introduces a sustainable scaffold designed by integrating copper-doped natural hydroxyapatite quantum-dots (Cu-HA QDs) and graphene oxide (GO) into a polycaprolactone (PCL) matrix using 3D printing technology, to address the dual requirements of osteogenesis and angiogenesis in large bone defects. HR-TEM and synchrotron SAXS/WAXS investigations of the Cu-HA QDs exhibited a highly crystalline hexagonal structure with distinct QD architecture, and core-level HR-XPS analysis confirmed Cu²⁺ substitution for Ca²⁺ within the HA lattice. Incorporating Cu-HA–GO nanocomposites significantly improved the physicochemical properties of the PCL scaffolds, including enhanced wettability, accelerated hydrolytic degradation, and enhanced mechanical stiffness. Under basal culture conditions, the PCL/Cu-HA–GO scaffolds significantly promoted mesenchymal stem cell proliferation, extracellular matrix mineralization, and differentiation. Furthermore, robust expression of key osteogenic genes ALP, RUNX2, and OCN increased by 28-, 33-, and 21-fold, respectively, and angiogenic genes HIF-1α and Ang1 increased by 45- and 18-fold, respectively. Immunofluorescence staining demonstrated strong osteocalcin signals and widespread formation of CD31-positive capillary-like structures throughout the scaffold, highlighting its unique potential to enhance bone regeneration and vascularization concurrently. These results present the 3D-printed PCL/Cu-HA–GO scaffolds as a promising, sustainable, and superior dual-functional osteogenic and angiogenic performances, offering an effective alternative for large/critical-size bone defect regeneration.</p
Study of gold and bismuth electrical contacts to a MoS2 monolayer
No full textData supporting the publication A. Zielińska et al., Study of gold and bismuth electrical contacts to a MoS2 monolayer, Solid State Communications 397, 115824 (2025).The xlsx files include all data that was presented in the manuscript. The files are named as the corresponding figures.Electrical measurements: I-V characteristics were measured in a wide temperature range in a superconducting magnet system (Oxford Instruments). Yokogawa 7651 was used as a voltage source, and Aglient 34410A multimeter with Ithaco 1211 preamplifier were used to measure drain- source voltage. Keithley SMU 2400 source meter was used to set backgate voltages.Optical spectroscopy: measurements were performed in an optical helium flow cryostat (Oxford Instruments). The excitation source for microphotoluminescence was a 532 nm continuous wave laser. The white light source for microreflectance was a Tungsten-Halogen Light Source (Thorlabs). The light was spatially filtered through a 50 μm pinhole, which yields the final spot size of ∼ 4 μm. The laser light and the white light were focused on the sample surface by 0.75 NA and 50× microscope objective (Mitutoyo). The same objective was used to collect the output signal, which was then directed to the spectrometer (500 mm focal length, 300 groove/mm grating and 150 μm slit width) equipped with a liquid nitrogen cooled CCD camera (Princeton Instruments).</p
