Extracorporeal membrane oxygenation (ECMO) is widely used to save patients with severe respiratory failure. Although the mainstream ECMO membrane material poly(4-methyl-1-pentene) (PMP) provides excellent gas permeability, its hydrophobicity leads to thrombosis during clinical application. Recently, polymers

Redox flow batteries (RFBs) are promising for long-duration grid-scale sustainable energy storage. The ion-exchange membrane is a key component that d…

The SEM images of the AZ31 composites reinforced with 5 vol.%, 10 vol.% and 15 vol.% TiC are presented in Fig. 2(a–c). There are no visible flaws or microporosity in the micrographs of all the samples. The TiC particles are uniformly distributed throughout the matrix and exhibit strong interfacial bonding with the AZ31 alloy. The EDS mapping result for the AZ31/15 vol.% TiC composite is shown in Fig. 2(d).The elemental distribution maps clearly confirm the successful incorporation of TiC particles into the matrix, illustrating the spatial distribution of Mg, Zn, C and Ti within the analyzed area. “Furthermore, the AZ31/15 vol.% TiC composite exhibits a significantly refined grain structure, with an average grain size of approximately 8 µm, as reported in a previous study [ 30], compared to the coarser grain size of about 60 µm observed in the unreinforced AZ31 alloy. This type of structure can be attributed to dynamic recrystallization encouraged during FSP. The presence TiC particles are found to actively prevent grain growth, therefore improving the general microstructural features of the composite. Hardness and wear test results Table 2 summarizes the hardness test findings for the AZ31 alloy and its composites. Higher TiC concentration clearly shows a...
