| Metallurgical solids, including alloys and intermetallic compounds of the late transition metals, represent a large class of technologically important materials that have widespread use in variety of applications. Most of these solids are synthesized using high temperature reactions (> 1000 deg. C) because solid-solid diffusion is the rate limiting step in their formation. In many cases, low-temperature strategies can (< 300 deg. C) be used to form metallurgical solids under conditions where the diffusion problem can be avoided or minimized. These mild synthetic strategies sometimes offer advantages over traditional high-temperature techniques, including the ability to (a) access new or elusive structures, (b) control important morphological features such as nanoscale shape and size, and (c) use inexpensive benchtop processes to form materials into films, coatings, and micropatterned structures. This talk will discuss our ongoing attempts to expand capabilities in nanoscience by thinking "green", particularly in terms of energy efficiency. The focus will be on elaborating new capabilities and nanomaterials that emerge as a result of environmentally-conscious thinking, rather than the formation of existing materials by alternative means. New results on the formation of metallurgical solids using safe, renewable, and edible "solvents" will also be described. |
