The behaviour of carbon and nitrogen species in mantle fluids depends on oxygen fugacity (fO2). Estimates for continental lithospheric mantle (CLM) within the Kaapvaal20, Slave21and Siberian22,23cratons show thatfO2generally decreases depthward from +1 ΔlogfO2FMQ (Fayalite-Magnetite-Quartz oxygen...
Oxygen gas permeability and the mechanical properties of poly (n-butylamino)-(di-n-hexyamino) phosphazene Membranes Poly ( n -butylamino)-(di- n -hexylamino)-phosphazene was prepared by the reaction of poly (dichlorophosphazene), di- n -hexylamine and n -butylamine usin... M Kajiwara - 《...
” followed by the formation of g–C3N4–like polymer sheets with conjugated triazine or tri-s-triazine repeating units. To obtainpolymeric carbon nitride, high temperatures are used, and for the synthesis of carbon nitride quantum dots, low temperatures [60] are used in an oxygen-free ...
1c, results of full-scale XPS spectra analysis demonstrate that the prepared CDs consist of carbon (C), nitrogen (N), and oxygen (O) elements with atomic ratio of 78.17, 10.84, and 10.99%, respectively. High-resolution XPS spectra are shown in Fig. 1d–f. High resolution C 1s spectra...

The early studies on karst processes mainly calculated the carbonates dissolution rates by empirical formula or by using the standard limestone tablet test method (Pulina, 1974; Gams, 1981; Drogue et al. 1987). From 1990s to the beginning of this century, more comprehensive approaches were develop...
