We have carried out combustion synthesis of nanocrystalline Y2O3 materials using hexamine, polyethylene glycol(200) (PEG(200)), and ethylene glycol (EG) as fuels. In addition, the impact of mechanical stirring of commercial Y2O3 powder with various dilutions of PEG(200) with distilled water as a solvent was also examined. The as-prepared combustion product of the hexamine is significantly different from other fuels (PEG(200) and EG). The annealed combustion products crystallize in the pure cubic Y2O3 phase. The combustion product of PEG(200) reveals a maximum weight loss of ~46% at 800°C in the TG curve. The UV-Vis-NIR features of different samples show quite interesting results. The Eg values obtained from the Tauc plots are found in the range of 5.48 to 5.71 eV for the different samples. The observed strong FTIR band at 560 ~ 415 cm−1is owing to the vibrational Y-O bond in the present series samples. The Raman spectra show the highest intensity peak at wavenumber 374 cm−1is owing to the Fg vibrational mode of the Y2O3phase. Agglomerated nature of nanoparticles is seen in the Y2O3 phase samples obtained from EG and hexamine as fuels.

“…In UV–visible spectroscopy, a strong absorption band was observed at 290 nm, which is in agreement with the literature and confirms the formation of Y 2 O 3 NPs (Figure S7). The FT-IR spectrum was recorded in the range of 4000–450 cm –1 (Figure B), and the peaks were obtained at 462 and 577 cm –1 corresponding to Y–O stretching, thus confirming the formation of Y 2 O 3 NPs. The broad peak at 3317 cm –1 indicated the presence of moisture, while peaks at 1490 and 1396 corresponded to the −COOH stretching.…”

Chronic wounds are a major healthcare challenge owing to their complex healing mechanism and number of impediments to the healing process, like infections, unregulated inflammation, impaired cellular functions, poor angiogenesis, and enhanced protease activity. Current topical care strategies, such as surgical debridement, absorption of exudates, drug-loaded hydrogels for infection and inflammation management, and exogenous supply of growth factors for angiogenesis and cell proliferation, slow the progression of wounds and reduce patient suffering but suffer from low overall cure rates. Therefore, we have developed a proteolytically stable, multifunctional nanoparticle loaded-peptide gel with inherent anti-inflammatory, antibacterial, and pro-angiogenic properties to provide a favorable wound healing milieu by restoring impaired cellular functions. We have fabricated a self-assembled, lauric acid-peptide conjugate gel, LA-LLys-DPhe-LLys-NH2, loaded with yttrium oxide (Y2O3) nanoparticles (NLG). Gel formed a nanofibrous structure, and nanoparticles were passively entrapped within the network. The surface morphology, stability, viscoelastic, and self-healing characteristics of gels were characterized. It showed a high stability against degradation by proteolytic enzymes and highly potent antibacterial activities against E. coli and S. aureus due to the presence of positively charged side chains of lysine in the peptide chain. It also exhibited an excellent antioxidant activity as well as ability to stimulate cell proliferation in murine fibroblast (L929) cells and human umbilical vein endothelial cells (HUVECs). The incorporation of nanoparticles promoted angiogenesis by upregulating pro-angiogenic genes, vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF2), and epidermal growth factor (EGFR), and the gel caused complete wound closure in cells. In summary, the Y2O3 nanoparticle-loaded lauric acid-peptide conjugate gel is able to elicit the desired tissue regeneration responses and, therefore, has a strong potential as a matrix for the treatment of chronic wounds.

“…In fact, inspecting this value shows a deviation of 2% from the experimentally available results, which indicates the reliability in predicting structural parameters for such systems. Therefore, the computed bond lengths Y─O are found to be for the 24d site Y1─O = 2.27 Å, 2.30 Å and 2.36 Å and for the 8b site Y2─O = 2.31 Å, which are also fairly consistent with available experimental data . The calculated elastic constants C ij of the cubic Y 2 O 3 were found to be C 11 = 222 GPa, C 44 = 84 GPa and C 12 = 104 GPa.…”

In this contribution, we report reliable ab initio quantum mechanical simulations of a variety of physical properties concerning yttrium sesquioxide (Y2O3) in different arrangements from the bulk, the monolayer (h‐Y2O3), to the (n,0) single‐walled nanotubes in the range from n = 6 to 32, for geometry optimization and vibrational properties. Structural parameters, phonon wavenumbers, infrared (IR) and Raman intensities, and elastic constants are computed via density functional theory (DFT/B3LYP) where the trend towards the (h‐Y2O3) monolayer for large nanotube radius is discussed. We firstly report combined experimental and computational studies on the structural and vibrational properties of the bulk Y2O3. Then, IR and Raman spectra of all arrangements are simulated via the coupled perturbed Hartree–Fock and Kohn–Sham (CPHF/KS) computational schemes. For the (n,0) Y2O3 nanotube family, two sets of IR active phonon modes in the (200–400 cm−1) and (600–900 cm−1) ranges are determined. Both of them tend smoothly with different slope, towards the optical vibrational modes of the h‐Y2O3 single layer. Three sets of active phonon bands are obtained in their Raman spectrum. The first one, in the 0–100 cm−1 range contains two phonon modes, their vibration wavenumbers tend to zero at very large tube radius and are found to be connected to the elastic constants C11 and C66 of the h‐Y2O3 monolayer as the 1D → 2D transition is approached. The second one, in 200–400 cm−1 range tends to the optical mode E′ (ν = 308 cm−1) of the monolayer. The third set, in the 600–900 cm−1 range contains two active modes, their intensities tend to zero in the limit of large nanotube without change in their vibration wavenumbers.
