Cryptomelane-type manganese oxide (OMS-2) has been widely used to explore the semiconducting and catalytic properties of molecular sieves with mixed-valent frameworks. Selective synthesis of patterned ...

Figure 1: 18-component synthesis of nanocontainer 1 and imine bond reduction. Place a 2,000 ml three-necked round-bottomed flask in a heating mantle. Equip the reaction flask with a 250 ml addition ...

occupying the octahedral holes. Notice that the octahedral holes are along the edges (for a net of three cations) and in the center of the cube (one more cation). Thus we have four anions (FCC) and ...

Zinc sits at the heart of many bacterial enzymes, so one of our immune system's simplest defenses is to keep zinc out of reach. Calprotectin, a neutrophil protein abundant at infection sites, is ...

Spinel, MgAl 2 O 4 (download cif), is a rare gemstone that was used to imitate rubies. The structure has face-centered cubic symmetry, and is a little heavy to understand. The general formula is AB 2 ...
