“…The particle size of the Fe 3 O 4 remained stable at 8.1 nm, while that of the ZnO increased slightly from 35.4 to 37.8 nm. Generally, the increasing ZnO content increased the ZnO particle size, indicating that this could be an effective strategy to control the agglomeration of Fe 3 O 4 [28].…”

In the present study, the eco-friendly and economical methods have been developed by employing natural iron sand as a main precursor to create Fe3O4/ZnO nanocomposites (NCs). The formation of Fe3O4/ZnO NCs was confirmed using XRD, synchrotron-based SAXS, FTIR spectroscopy, and SEM. The XRD results revealed that the Fe3O4 and ZnO crystallised spinel cubic and hexagonal wurtzite structures. The SAXS results exposed the construction of fractal dimension with the values of 3.20–3.70, which indicated a compact structure in 3-dimensions. The SEM images showed that the morphology of the samples tended to agglomerate in nanometric size. The FTIR spectra proved the presence of the Fe–O and Zn–O bonds as the main components of the NCs. The UV–vis spectroscopy analysis revealed that the bandgap energy of the Fe3O4/ZnO NCs ranged from 2.244 to 3.533 eV. Furthermore, the Fe3O4/ZnO NCs demonstrated superparamagnetic behaviour with the blocking temperature below 212 K, and their saturation magnetisation increased with increasing Fe3O4 content. Interestingly, all samples demonstrated excellent inhibitory performance against C. albicans, which indicates that the Fe3O4/ZnO NCs synthesised by eco-friendly and economical methods from natural iron sand for the first time are novel candidates for use as high-performance antifungal agents.

“…For example, nanosized HAps have been shown to have a slightly larger band gap than larger particles due to quantum connement effects. 53,54 Additionally, the shape of HAp particles can also affect their band gap due to the variation of their porosity, pore sizes, and surface roughness. 54 However, the band gap changes in our work are distinct and could instead be affected by various defects and compositions, as defects and disorders in the crystal lattice can introduce energy levels within the band gap.…”

Sejauh ini inovasi raw material pasta gigi herbal yang berasal dari limbah masih jarang dikembangkan, cangkang kepiting menjadi material yang berpotensi untuk menjadi bahan baku dalam pembuatan pasta gigi herbal. Tujuan penelitian ini yaitu mengembangkan limbah cangkang kepiting menjadi material yang memiliki nilai ekonomi. Penelitian ini dilakukan dengan ekstraksi dan sintesis sederhana. Karakterisasi XRD, FTIR, dan SEM-EDX digunakan untuk menganalisis kristalinitas, gugus fungsi, dan morfologi kitosan. Hasil analisis menunjukkan struktur kitosan membentuk kristalin yang ditunjukkan dengan terkonfirmasinya tiga puncak tajam pada 2-teta 19o, 26o, dan 29o. Hasil analisis puncak serapan FTIR menunjukkan terdeteksinya 5 gugus fungsi utama kitosan pada bilangan gelombang 3458 cm-1, 2895,15 cm-1, 1654,92 cm-1, 1587,42 cm-1, dan 1386,82 cm-1 adalah OH stretching, CH(CH3) bending, C=O (-NHCOCH3) stretching amida I, NH (-NHCOCH3) bending amida II, CH (-CH2) bending sym secara berturut-turut. Morfologi kitosan yang disintesis dari cangkang kepiting berpori, bergelombang, dan bentuknya tidak teratur serta unsur yang terkandung yaitu C, O, Ca, dan Si.
