The micro morphology of limestone sorbent is a key for improving the SO2 removal efficiency in the coal-fired power plant. The tube furnace system was built for imitating the indirect desulfurization reaction in traditional boiler atmosphere (65%N2, 15%CO2, 4.7%O2, 15%H2O, 0.3%SO2) and the direct desulfurization reaction in oxygen-fired atmosphere (80%CO2, 4.7%O2, 15%H2O, 0.3%SO2). The reacted ...

Introduction: Akaganeite (β-FeOOH) is an Fe(III) (hydr)oxide with a tunnel structure usually occupied by chloride. Akaganeite has been recently discovered in a mudstone on the surface of Mars by the Chemistry and Mineralogy (CheMin) and Sample Analysis at Mars (SAM) instruments onboard the Mars Science Laboratory (MSL) Curiosity Rover in Gale crater [1, 2]. Akaganeite was detected together with...

The power of the state-of-the-art neutron powder diffractometer suite at the Institut Laue–Langevin for investigating the structure of nondeuterated materials is presented using gypsum, CaSO4 2H2O, as a reference material. It is shown that flexible modern neutron powder diffraction instruments at reactorbased sources can yield data with sufficient counting statistics above the incoherent scatte...

We have developed a LiF/CaF2:Tb eutectic composite as novel thermoluminescence (TL) dosimetric material. The was obtained using melt-solidification method with lower melting temperature than that of LiF and CaF2. results the PL emission excitation spectra, X-ray induced radioluminescence decay curve, TL spectrum indicate emissions are due to 4f-4f transitions Tb3+ ion. integrated intensity 3.6 ...
