This work demonstrates a phenomenon that preserves the traditionally metastable anatase crystal structure of thin titania (TiO2) films along a two-dimensional oxide interface at temperatures well in excess of those that normally trigger a full polymorphic transformation to rutile in higher dimensionality crystalline powders. Whereas atomic surface mobility appears to dominate polymorph transfor...

Quicklime is a widely used industrial chemical and its characteristics may be affected by the limestone calcination temperature. The present study investigated quicklime obtained from after at different temperatures (800, 900, 1000 ℃) six geological-different mines in West Sumatera, Indonesia. X-ray fluorescence (XRF) analysis was performed to characterize elemental compositions quicklime. stoi...

Two nanocrystalline palladium-supported tin oxide catalysts for water denitration were synthesized by a modified sol–gel technique using appropriate chloride precursors for both support and active phases, and citric acid to tune the rate of hydrolysis and condensation. The difference among sample preparation procedures refers to the moment of the noble metal loading to the support, as well as t...

Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles are formed from the calcination of non-porous CPPs.

Globally increased bivalve aquaculture production results in a vast amount of by-product discharges such as scallop shells. Utilization these wastes to produce new products antibacterial agents can cooperate reduce environmental problems and provide high value-added product at lower cost. In this study, shells are heat-treated 800°, 900°, 1000°, 1100°C for 4 hours atmospheric conditions. X-ray ...
