Over the last decade our view of chemistry has evolved substantially. Whereas individual researchers previously focused on specific areas of chemistry, such as inorganic, organic, etc. we now take a more holistic approach. Effective and efficient research projects now incorporate whatever aspects of the chemistry subdisciplines that are needed to complete the intended work. The main group elements have always been used in this manner. Depending on the use of the elements, the resulting work can be described under any heading of chemistry. The group 13 elements have been special in this regard...

Aluminum, bound almost exclusively to oxygen in various combinations, is the most abundant metal in the earth's crust and, therefore, of great commercial potential. Once methods were developed (in the 1880's) to free useable quantities of the element from oxygen, applications for the element began developing rapidly. This growth has resulted in the ubiquity of the metal in today's world. Therefore it can be found intentionally introduced in many products in direct contact with human beings. It is commonly known that soluble forms of aluminum aretoxic to living organisms. However, aluminum is...

The present issue of Structure and Bonding is dedicated to applied group 13 chemistry, particularly for the elements boron and aluminum, and to a lesser degree gallium and indium. Although boron is a trace element (0.01 g kg 1) in the earth's crust, it has been concentrated in a few locations by geochemical processes and is relatively easy to mine as borax. Aluminum, on the other hand, is the most abundant metal in the earth's crust (82 g kg 1) and dispersed widely throughout the globe. Thus, boron and aluminum are readily available and their associated products or compounds are usually...

Interest in the transition metal oxides with perovskite related structures goes back to the 1950s when the sodium tungsten bronzes NaxWO3 were shown to be metallic [1 ], the system Lal_xSr~MnO3 was found to contain a ferromagnetic conductive phase [2], and La0.sSr0.sCoO3 was reported to be a ferromagnetic metal, but with a peculiar magnetization of 1.5 #a/Co atom [3]. Stoichiometric oxide perovskites have the generic formula AMO3 in which the A site is at the center of a simple cubic array of M sites; the oxide ions form (180 4)) M O M bridges to give an MO3 array of corner shared MO6/2...
