The fundamental importance of aluminum to life and modern civilization helps explain the importance of the advance, researchers say. It's the most abundant metal in the Earth's crust, but almost never is found in its natural state. The deposition and migration of aluminum as a mineral ore is controlled by its aqueous chemistry. It's found in all drinking water and used worldwide for water treatment. Aqueous aluminum plays significant roles in soil chemistry and plant growth.
Aluminum is ubiquitous in cooking, eating utensils, food packaging, construction, and the automotive and aircraft industries. It's almost 100 percent recyclable, but in commercial use is a fairly modern metal. Before electrolytic processes were developed in the late 1800s to produce it inexpensively, it was once as costly as silver.
Now, aluminum is increasingly important in electronics, particularly as a "green" component that's cheap, widely available and environmentally benign.
Besides developing the new platform, this study also discovered one behavior for aluminum in water that had not been previously observed. This is a "flat cluster" of one form of aluminum oxide that's relevant to large scale productions of thin films and nanoparticles, and may find applications in transistors, solar energy cells, corrosion protection, catalytic converters and other uses.
Ultimately, researchers say they expect new technologies, "green" products, lowered equipment costs, and aluminum applications that work better, cost less and have high performance.
