Radiation-assisted reduction of graphene oxide by aloe vera and ginger and their antioxidant and anti-inflammatory roles against male mice liver injury induced by gamma radiation

“…1 Researchers around the world have become motivated to discover the future potential applications of graphene and its derivatives for a wide range of applications, such as in flexible supercapacitors, 2 polymer reinforcement, 3,4 photocatalysts, 5 sensors, 6 and bio-imaging. 7 There are many different graphene synthesis techniques, such as epitaxial growth, 8 chemical vapor deposition, 9 mechanical cleavage, 10 and liquid-phase exfoliation. 11 Despite the low quality of the produced graphene, reducing graphene oxide (GO) is a popular method for graphene production, especially when considering large-scale production.…”

Electronic structure of 30∘ twisted double bilayer graphene

“…The 30 • TBG, an incommensurate bilayer configuration, has been grown successfully on H-SiC(0001) [17], Pt(111) [18], Cu-Ni(111) [19], and Cu [20,21] surfaces. As the first two-dimensional quasicrystal based on graphene, 30 • TBG has received increasing attention both experimentally and theoretically [22][23][24][25][26][27][28]. A method to grow high-quality 30 • TBG epitaxially on SiC using borazine as a surfactant has also been proposed [22].…”

Interlayer hybridization in graphene quasicrystal and other bilayer graphene systems

“…Introduction.-Besides the emergent correlated effects [1][2][3][4][5][6][7][8][9][10][11] in slightly twisted bilayer graphene, the recently discovered quasicrystal [12,13] in 30 • incommensurately twisted bilayer graphene has also attracted considerable interest in both experiment [12][13][14][15][16][17][18][19][20] and theory [21][22][23][24][25][26][27][28][29]. Several synthetic methods, including chemical vapor deposition and carbon segregation from the bulk during high temperature annealing, have been used to successfully grow graphene quasicrystal on SiC [12,14], Pt [13], Cu [18][19][20] and Cu-Ni alloy [15] substrates. The quasiperiodicity in these samples is experimentally identified by the low-energy electron diffraction [12][13][14][15], transmission electron microscopy [12,19], scanning tunneling microscopy [16] and Raman spectroscopy [13,…”
