2019/3/12New oxides of Cr, Mn and Fe have been produced, all of which are formed as nanocrystalline powders, as seen by high-resolution transmission electron microscopy (HR-TEM). The first chromium-gallium mixed oxide is thus formed, with composition 0.33Ga1.87Cr0.8O₄ ( = vacant site). 84 Bulgarian Chemical Communications, Volume 45, Number 1 (pp. 84 – 89) 2013 Crystallization behaviour and magnetic properties of sodium-silicate glasses containing iron and manganese oxide 1*Ruzha Harizanova, 1Ivailo Gugov, 2Christian Rssel 1University of

Manganese oxide (MnO 2) has been reported to have a high dielectric constant of nearly 10 000 []; therefore, excellent coupling with MW radiation can be expected. MW irradiation may produce interesting effects in comparison with conventional heating (CH).

Nanocrystalline CeO 2 powders were prepared electrochemically by the cathodic electrogeneration of base, and their sintering behavior was investigated. X‐ray diffraction and transmission electron microscopy revealed that the as‐prepared powders were crystalline cerium(IV) oxide with the cubic fluorite structure.

Nanocrystalline iron and manganese oxide minerals play a critical role in controlling the geochemistry of trace elements and heavy metals. These minerals are common in many environments, including cave and karst systems. However, little is understood about the

After acycle of catalytic activity experiment, although the particle sizes of nanocrystalline manganese oxides grow to a certain extent, they still keept in nanometer level. This indicatesthat the nanocrystallinen manganese oxide powders arerelatively stable as catalysts for CO oxidation, so they canbe used as cheap and easily-get catalysts for CO conversion.
