![]() The temperature at which the liquid–gas phase change occurs. The temperature at which the solid–liquid phase change occurs. The arrangements of electrons above the last (closed shell) noble gas. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The atomic number of each element increases by one, reading from left to right.Įlements are organised into blocks by the orbital type in which the outer electrons are found. Members of a group typically have similar properties and electron configurations in their outer shell.Ī horizontal row in the periodic table. doi: 10.4236/ vertical column in the periodic table. Synthesis of Chromium(III) Oxide Nanoparticles by Electrochemical Method and Mukia Maderaspatana Plant Extract, Characterization, KMnO4 Decomposition and Antibacterial Study. Influence of multiple oxide (Cr2O3/Nb2O5) addition on the sorption kinetics of MgH2. Catalytic properties and nature of active sites. Ethane dehydrogenation over pore-expanded mesoporous silica-supported chromium oxide: 2. Facile green synthesis approach for the production of chromium oxide nanoparticles and their different in vitro biological activities. Ecofriendly synthesis of silver and gold nanoparticles by Euphrasia officinalis leaf extract and its biomedical applications. Hence, green synthesized Cr 2O 3 nanoparticles could prove to be promising candidates for future biomedical applications.Ībutilon indicum (L.) Sweet Cr2O3 antibacterial anticancer antioxidant biocompatibility green synthesis. These results suggest that the green synthesized Cr 2O 3 nanoparticles' enhanced biological activities might be attributed to a synergetic effect. Moreover, cytobiocompatibility analysis displayed that they presented excellent biocompatibility with Vero cell lines than that of chemically synthesized Cr 2O 3 nanoparticles. ![]() The green synthesized Cr 2O 3 nanoparticles exhibited significant anticancer and antioxidant activities against MCF-7 cancerous cells and the linoleic acid system, respectively, compared to chemically synthesized Cr 2O 3 nanoparticles. The results demonstrated that the green synthesized Cr 2O 3 nanoparticles exhibited superior antibacterial activity in terms of zones of inhibition (ZOIs) against Gram-positive and Gram-negative bacteria compared to plant extracts and chemically synthesized Cr 2O 3 nanoparticles (commercial), but comparable to the standard drug (Leflox). Moreover, the cytobiocompatibility was analyzed against the Vero cell lines using MTT and a live/dead staining assay. Antioxidant activity was investigated in the linoleic acid system. The anticancer activities were determined against Michigan Cancer Foundation-7 (MCF-7) cancer cells using MTT and a live/dead staining assay. ![]() subtilis using agar well diffusion and a live/dead staining assay. The antibacterial activity of the green synthesized nanoparticles was evaluated against four different bacterial strains, E. The average size of the nanoparticles ranged from 17 to 42 nm. The X-ray diffraction technique confirmed the purity and crystallinity of the Cr 2O 3 nanoparticles. Different characterization techniques were used to characterize the synthesized nanoparticles such as X-ray diffraction (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM), Energy-dispersive X-ray (EDX), Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and ultraviolet-visible (UV-VIS) spectroscopy. This study deals with the green synthesis of chromium oxide (Cr 2O 3) nanoparticles using a leaf extract of Abutilon indicum (L.) Sweet as a reducing and capping agent.
