“…The experimental tests show that sandwich specimens were damaged under the effect of impact load. Various criterions were selected as the fibre failure criterion for the damage model in the literatures [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59]. To realise the damage onset of the specimens in the form of numerical simulations, a damage criterion according to the Hashin's failure criterion is used.…”

High-speed impact behaviour of composite sandwich panels reinforced by nano-SiO 2 has been studied in the present article. The sandwich panels were manufactured by glass/fibre epoxy composite face sheets and an M-shaped core using the vacuum-assisted resin transfer moulding (VARTM) method. To enhance the mechanical strength of the matrix, especially impact resistance, the nanoparticles were added to the resin epoxy matrix as filler. A scanning electron microscope (SEM) was utilised to observe the microscopic structure of the composites. The experimental results indicated that adding 1-3 wt-% of nano-SiO 2 into the matrix remarkably increased the impact resistance of the composite. In order to validate the results, the experimental data were compared to the finite element models, and good agreement was observed.

“…Furthermore, its low thermal neutron absorption cross section renders it an ideal material for the cladding of fuel elements in nuclear power plants [6]. Over the operational lifespan of a nuclear reactor, the cladding of fuel elements is subjected to cyclic loading, as a consequence of the vibrations induced by fluid movement within the reactor, which can precipitate fatigue failure [6,7]. Consequently, industrial pure zirconium must exhibit not only exceptional corrosion resistance but also superior mechanical properties to ensure the integrity and longevity of the fuel element cladding.…”

Industrial pure zirconium plays an essential role as a structural material in the nuclear energy sector. Understanding the deformation mechanisms is crucial for effectively managing the plasticity and texture evolution of industrial pure zirconium. In the present study, the texture and microstructure evolution of industrial pure zirconium during the cold-rolling process have been characterized by XRD, EBSD, and TEM. The influences of various twins on texture evolution have also been simulated by the reaction stress model. The effects of slip and twinning on the deformation behavior and texture evolution have been discussed based on crystallographic and experimental considerations. Cold rolling yields a typical bimodal texture, resulting in the preferential <2110>//RD orientation. The activation of the deformation mechanisms during cold rolling follows the sequential trend of slip, twinning, local slip. Experimental characterization and reaction stress simulation illustrate that T1 twins dominate in the early stage, whereas C2 twins develop at the later stage of the cold-rolling process. Twinning, especially the T1 twin, contributes to the formation of the {0001}<1010> orientation.

“…The WO 3 is a non-toxic, n-type semiconductor that contains bandgap energy of approximately 2.6-3.0 eV and the option of being evoked by visible light [40] while offering desirable sensing properties, especially high sensitivity towards nitrogen oxides. The appearance of this compound was observed in the form of yellow crystals that are consisted of chemical compounds in between its oxygen and tungsten [41,42]. This metal oxide can have a variety of crystal structures that depend on the applied temperature and growth conditions, which include quadrilateral, hexagonal, single-millimetre, and right-angled networks [43].…”

In the present work, the synthesis of tungsten oxide nanosheets (WO 3 -NS) was performed through a sol-gel method with the usage of Na 2 WO 4 as the tungsten source in a gelatin solution that functioned as a novel green stabilising agent. The synthesised WO 3 -NS were characterised by the analysing methods of XRD, FESEM/EDX, FTIR, TGA/DTG, UVvis, Raman, and VSM. The photocatalytic activity of the product is investigated through the exertion of methylene blue pigment, while the obtained results reported 95% of degradation in 187 min under the light of a mercury vapour lamp. The cytotoxicity effect of WO 3 -NS on the human liver (Huh-7) cell line was evaluated by the means of the MTT method, which displayed the inhibiting capabilities of these nanosheets regarding cancer cells.
