“…[15][16][17] Al-catalysed water oxidation is one of the widespread chemical reactions. [18][19][20] The uniqueness of the Al-containing materials lies in the fact that aluminium is a trivalent atom in larger clusters and monovalent in smaller clusters due to the large energy gap between 3s and 3p electronic states. [21] Additionally, Aluminium and carbon-containing smaller molecules have astrochemical significance due to their abundance in the interstellar medium.…”

The computational investigation on the equilibrium geometries, electronic structures, reactivity, and stability of C/C2-doped Aln0, (n=2-7) clus-ters at B3LYP-D4/def2-TZVPP level of theory. The lowest energy structures of AlnC1,20, clusters are more stable when the carbon atoms are inserted in the aluminium cluster. The stability of the clusters was determined by various parameters such as binding energies, dissociation reac-tion energies, a second-order difference of energy, chemical hardness, ionization energy, and electron affinity. The results show the singlet clus-ter (Al2,4,6C1,2 and Al3,5,7C0-20,) shows greater stability than the doublet clusters (Al3,5,7C0-2 and Al2,4,6C1,20,) followed by triplet clusters (Al2,4,6). The stability of cationic species is less than that of neutral species, but anionic clusters are shown to be more stable than the neutral species. The present study can be significant to know the stability and reactivity of the metal clusters upon carbon doping. Such materials have great importance in combustion, material science, and astrochemical community.

“…Then, the suspension was incubated on a water bath with stirring at 60°C for 1 h. The reaction products were separated by centrifugation, washed several times with deionized water, and finally dried at 120°C for 2 h. In the hydrothermal process, 1 g of AlN/Al nanopowder is treated with 100 ml of deionized water in a stainless steel autoclave with a Teflon insert at room temperature. The hydrothermal treatment was performed at 200°C for 6 h. The oxidation of AlN/Al nanopowder in wet air [21] was performed in the climatic chamber TXW-60 at 60°C and 80% relative humidity for 24 h. The reaction products were dried at 100°C for 2 h.…”

Abstract. In recent years, researches have paid much attention to the physical, chemical, biophysical and biochemical properties of a cell surface. It is known that most of the cells' surfaces are charged. This charge depends on the biochemical structure of the cell membranes. Therefore, measurement of a cell surface charge is a significant criterion that gives information about the cell surface. Evaluation of the cells zeta-potential is important to understand the interaction mechanisms of various drugs, antibiotics, as well as the interaction of nanoparticles with the cell surface. In this study, we use the dynamic light scattering method to detect the zeta-potential change of Neuro-2a tumor cells. It has been observed that zeta-potential shifted to negative values after exposure to metal oxide nanoparticles and inducing apoptosis.

“…Hence nanomaterials of different shapes and dimensions should be studied by visualization in the cell as well as by imaging and sensing for diagnostic and therapeutic purposes. One of the most important and demanded nanomaterials is alumina nanoparticles [9][10][11]. Recent studies have shown that the biological activity of alumina nanoparticles is due to their physical and chemical characteristics, such as shape, size, specific surface area, and other [12].…”

The paper presents the toxicity evaluation of nanostructures on the basis of alumina of different shape (nanofibers, nanoplates, nanosheets, nanosheet agglomerates) and with similar physical and chemical properties (particle size, specific surface area, phase composition, and zeta potential). The nanostructures were examined by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), low-temperature nitrogen adsorption, and dynamic light scattering (DLS). The cytotoxicity of nanostructures was estimated using L929 fibroblast cells and Neuro-2a tumor cells. It has been found that the L929 cells are less subject to the influence of alumina nanoparticles than the Neuro-2a tumor cells. Probably, the differences in the proliferation activity of normal and tumor cells in contact with the synthesized nanostructures are due to a change in the pH of the cell microenvironment
