Transition metal oxides are also widely used electrode materials for supercapacitors [3]. They also have attracted more attention as support for the conducting-polymer electrode materials. MnO nanocrystals (a-MnO and P-MnO ) are the most used one among the metal oxides. 

This state exists as a manganate(V), the blue MnO Na3Mn04 lOHjO is isomorphous with Na3V04 (p. 374). 

P-MnOj pyrolusite (8) single chains of edge-shared (MnO ) octahedra (1x1 channels)... 

The crystal stmcture of ramsdeUite [12032-73-4] is similar to that of P Mn02 except that double chains of MnO octahedra are cross-Unked to adjacent double chains through the sharing of oxygen atoms located at the corners. RamsdeUite and pyrolusite are the only manganese dioxide phases where the composition approaches the stoichiometric Mn02 formula. Heating ramsdeUite to 250°C transforms it to pyrolusite. 

Trimethylchlorosilane TCS 14 readily transforms metal oxides such as ZnO, MgO, MnO, BeO, AI2O3, or Ti02 and oxides of transition metals such as SmO or Iu203 into the corresponding reactive anhydrous chlorides and volatile HMDSO 7 (b.p. 100°C) (Scheme 13.6). 

Allyl alcohols behave essentially as olefins towards MnO (p. 300).

Effects of soil pH on the Zn amount bound to the Fe oxide fraction (amorphous/crystalline Fe oxide and overall Fe oxide bound fractions) in soils from China with pH 3.73 - 8.1 and 0 -14.7% CaC03 (after Han et al., 1995.

Zener appears to have been the first to consider this problem to some depth in his theoretical work on ferromagnetic crystals of the type l.a. Ca.MnO, (Zener 1951). For x = 0 one has LainMnin03 but for x > 0 some of the Mn will be 4+, and so we have the structure I. a " / a " Mn "(Mn CL in which some Mn-Mn pairs will be mixed valence, that is, MiF Mnj) or MnJ) Mn . Mnm is 3d4 (S = 2) and MnIV is 3d3 (S = 3/2), and Zener proposed that the excess electron (also called itinerant electron or Zener electron) on Mn111 can travel to the MnIV via a doubly-occupied p-orbital of...
