Haze related air pollution has become one of major environmental concerns in some Asian countries. Sulfate is a main component ambient particulate matter (PM) the urban environment during haze episodes. Among pollutants, sulfur dioxide (SO2) an important precursor sulfate and new atmospheric particle formation. However, under different conditions its underlying formation mechanisms are not clea...

The infiltration behaviour of CaO-MgO-Al2O3-SiO2 (CMAS) in Electron Beam Physical Vapour Deposited (EB-PVD) 7 wt% yttria stabilised zirconia (7YSZ) under controlled atmospheres (dry, wet and sulphurizing) was studied detail. microstructure the CMAS-infiltrated 7YSZ CMAS residue on top were analysed to interpret corrosion mechanisms. One major goals investigate stability CaSO4 into columns. At t...

Due to a mistake during the production process, fourth author’s name was incorrectly published as ‘Yang I. Huh’ instead of Il Huh’. The should be tagged in XML given Il’ and family ‘Huh’. cited indexing services ‘Huh Y’.

Phosphogypsum is a waste produced by the phosphate fertilizer industry. Although phosphogypsum is mainly calcium sulphate dihydrate, it contains elevated levels of impurities, which originate from the source phosphate rock used in the phosphoric acid production. Among these impurities, radionuclides from 238U and 232Th decay series are of most concern due to their radiotoxicity. Other elements,...

Single-distilled water encapsulated in graphene pockets has been studied by aberration-corrected high-resolution transmission electron microscopy and electron energy loss spectroscopy at an acceleration voltage of 80 kV. Inside the graphene pockets, crystallization and in situ crystal growth are reported and identified as the insoluble AII phase of CaSO4 (anhydrite) in a quasi-two-dimensional s...
