New Porous Structures from Layered Phosphonates, separation of 13.8Å. The layers are cross-linked into a three dimensional structure by virtue of the phosphonic acid bonding across two adjacent layers. It would be expected that this compound would be non-porous since the distance between adjacent organic pillars (crosslinks) along the layers is 5

A New Class of Gallium Arsenide Transistor: Realization Through a Molecular Designed Insulator,utions to area of electronic materials. However, any research program should follow two criteria. First, the area to be tackled should involve a real (not perceived) problem in materials science. Finding new syntheses for commercially available materials, while intellectually of interest, has little

,New, Hydrotalcite-Type Catalytic Materials: Preparation of the Series Mg4−xZnxAl2(OH)122 two broad groups: cationic clays, which nature prefers, and anionic clays. Anionic clays, which are the topic of our study, are rare in nature but relatively simple and inexpensive to prepare in the laboratory. Naturally occurring hydrotalcite, Mg.Al.(OH).CO.•4H.O, is an example of an anionic clay.

Zirconia: A Review of a Super Ceramic,ally controlling the conditions to produce a particular crystal phase are complex. Disagreements in the phase transformations of crystalline phases in zirconia still exist. These factors which make zirconia a very important ceramic material are reviewed in this chapter.
