partial molar enthalpies in the case of solutions as shown by Zielenkiewicz [ 15 ] in his study of mixing aqueous solutions of human serum albumin with aqueous solutions of NaCl; in this the mixture of albumin represents a matrix with a high carbon content

, FTIR spectra were recorded with KBr pellets on a Mattson GALAXY 5000 series FTIR spectrometer. Hydrogen and carbon content was determined by elemental analysis. EA measurements were performed in a Perkin Elmer 2400 series elemental analyzer, and were

that of the specimens of NRS (Natural River Sand) at 28 days of curing [ 21, 22 ]. In another study [ 23 ], two types of FA (Fly ash) were developed with class F (High carbon content) geopolymer fine aggregate (F-GFA) and class C (Low carbon content

element contents were measured with the inductively coupled plasma atomic emission spectroscopy technique after fusion with Li metaborate. The inorganic carbon content was measured volumetrically after HCl treatment. Uncertainties of the measurements were

A2 causes a shift of the TG curves to a high temperature. This is mainly due to comparatively less volatile matter and more fixed carbon content in coal A2, which makes the combustion reactivity of coal A2 worse than that of coal A1

temperature maxima shift to higher values with the increasing temperature and time of the isothermal transformation ( Fig. 3a , b). It proves that the amount of high-carbon austenite and carbon content increase in carbon-rich austenite. Then the peaks become
