Molecular Nanotechnology in Aerospace : 1999

چکیده
Recent progress towards molecular nanotechnology and potential aerospace applications is reviewed. Great strides have been made in understanding, visualizing, and controlling matter at the atomic scale. In particular, substantial progress has been made towards the construction of molecular computers. Some progress has been made towards understanding biological molecular machines and manipulating these machines for technological purposes. Also, several polymeric molecules, notably proteins, DNA, and RNA, can be automatically synthesized from precise specifications. This example of "programmable matter" has been used to produce at least one molecular mechanical device. However, integration of molecular components into larger atomically precise systems has made little progress. Scaling up molecular nanotechnology to produce macroscopic products of aerospace interest, for example, launch vehicles, will require large research and development investments. In particular, self-replication, proposed as a route to macroscopic molecular nanotechnology products, is a long way from fruition. This paper is a high-level discussion of molecular nanotechnology and some aerospace applications. Applications of importance to aerospace include computers, materials, and sensors. Research reviewed in [Globus 1998a] and [Globus 1998b], for the most part, is not revisited here. Also, this review is not exhaustive and much important and relevant work is not discussed.
