Influence of malting and fermentation on the nutritional composition, thermal stability, structural and physicochemical properties of a gluten-free flour blend of Digitaria exilis... by Oluwatobi Victoria Obayomi, Abiola Folakemi Olaniran, Stephen Olugbemiga Owa

“…Fourier transform infrared (FTIR) spectra showed changes and enhancements in band intensities, while scanning electron microscopy (SEM) revealed changes in microstructure due to fermentation and malting. X-ray diffraction showed that the combination of malting and enrichment with date powder increased the loss of crystallinity due to enzymatic hydrolysis and the amorphous nature of the date components. …”

New FeMoTaTiZr High-Entropy Alloy for Medical Applications by Miguel López-Ríos, Julia Mirza-Rosca, Ileana Mariana Mates, Victor Geanta, Ionelia Voiculescu

“…This work presents the creation and characterisation of an FeMoTaTiZr high-entropy alloy composed of chemical constituents with relatively low biotoxicity for human use, suitable for medical tools such as surgical scissors, blades, or other cutting tools. The alloy microstructure is dendritic in an as-cast state. The chemical composition of the FeMoTaTiZr alloy micro-zone revealed that the dendrites especially contain Mo and Ta, while the inter-dendritic matrix contains a mixture of Ti, Fe, and Zr. …”

Accelerated discovery of near-zero ablation ultra-high temperature ceramics via GAN-enhanced directionally constrained active learning by Wenjian Guo, Fayuan Li, Lingyu Wang, Li'an Zhu, Yicong Ye, Zhen Wang, Bin Yang, Shifeng Zhang, Shuxin Bai

“…Through only two iterations, this framework successfully identified the optimal composition of HfB2-3.52SiC-5.23TaSi2, which exhibits robust near-zero ablation rates under plasma ablation at 2500 ​°C for 200 ​s, demonstrating superior sampling efficiency compared to conventional active learning approaches. Microstructural analysis reveals that the exceptional performance stems from the formation of a highly viscous HfO2-SiO2-Ta2O5-HfSiO4-Hf3(BO3)4 oxide layer, which provides effective oxygen barrier protection. …”
