NASA requirements for computing and memory for microspacecraft emphasizes high density, low power, small size, and radiation hardness. The distributed nature of a storage elements in nanocrystal floating-gate memories leads to instrinsic fault tolerance and radiation-hardness. Nanocrystal-based memories also offer the possibility of a faster, lower power operation.

Detection of polyethylene single crystals deposited on reflecting substrate using incident light microscope
Electron microscope producing dark field images without resolution loss, using primary beam electrical tilting
Feasibility of high-energy-rate compaction to consolidate powder blends used in preparation of dispersion-strengthened alloys
Fiber optic window fitted to stainless steel field ion microscope permitting use of direct contact photography for image recording
Study establishes a relationship between radioresistance and the nucleolar stratification characteristics of various amoeba species. Two species of fresh water amoeba are studied with the electron microscope. The report discusses the nature of nucleolar layers and their possible relationship to the differences in radiosensitivity of the two amoeba species.
