“…Despite this multitude of factors, adsorption of polar organic molecules such as asphaltenes has been observed on many different mineral surfaces in petroleum-rich rocks (Balabin and Syunyaev, 2008;Buckley;Lebedeva and Fogden, 2011;Mendoza de la Cruz et al, 2009;Pernyeszi et al, 1998;Zheng et al, 2001). It is thus possible that adsorption also occurred on the surface of quartz crystals in the Zaonega organic-rich rocks, for instance, by attraction of polar macromolecules to negatively charged silanol (Si-O -) groups (Fig.7c) (Zheng et al, 2001).…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] From a fundamental point of view, tetrazoles are also particularly interesting systems, especially because of the tautomerism they may exhibit and their diversified photochemistry. 1,[21][22][23][24][25][26][27][28][29] Unsubstituted tetrazole, for example, was found to exist exclusively in the crystalline phases as the 1H-tautomer, [30][31][32] whereas in solution and gas phase 1H-and 2H-tautomers coexist, the population of the most polar 1H form increasing with the polarity of the solvent.…”

“…Each experiment was repeated ten times. The neuron number in an input layer (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) and the hidden neuron number (5-15) were varied. The number of iterations was 250.…”
