The magnesia (MgO) hydroxylation behavior in dilute suspensions (below 50% volumetric solid loads) has been extensively studied over the past decades due to its role refractory castables. However, equivalent effects on concentrated systems have not analyzed such a systemic way, although they are known be as or more deleterious than those observed systems. This study focuses of different sources...

Inelastic electron tunneling spectroscopy (IETS) is a unique surface and interface analytical technique using electron tunneling through a metal/insulator/metal tunneling junction at cryogenic temperatures. It gives the vibrational spectrum of a very thin (nm) insulator film and the adsorbed species on it. The high sensitivity, good resolution, and wide spectral range inherent in IETS enable us...

A rapid and clean method for the analysis of aflatoxins (AFs) was developed by using a new column and post-column photochemical derivatization HPLC with fluorescence detection. The new cleanup column consisted of magnesia and basic alumina poured on the top of a commercial multi-functional mini-column. It was extremely effective for the cleanup of AFs from raw peanut, corn, buckwheat and red pe...

There have been a number of different refractory binder systems introduced and utilized over the last 100 years. The most long-standing systems, and the ones employed through today, are based on aluminous cements or phosphates and water that chemically combine to form hydrates, which eventually harden. These traditional systems have limitations that refractory consumers have had to take into co...

The need for sustainable zero-carbon fuels to substitute the conventional fossil in transport field becomes unavoidable overcome depletion of petroleum reserves and global warming. Metal are promising energy-carrying materials that can be regenerated through carbothermal reduction their oxide combustion products. Their use is economically beneficial environmental-friendly when oxides recycled u...
