EFM-phase profiles show only the variation of electrostatic force which is strongly influenced by the surface conductivity of nanostructured arrays providing improved definition compared to conventional AFM. Here we apply it to carbon nanochannel arrays embedded within polyimide dielectric matrices. Copyright © 2012 World Scientific Publishing Co.

Major issues for waste forms are their behavior in response to α-decay damage and the presence of aqueous fluids for time scales on the order of 10 000 years. Studies of minerals from geological systems may reveal information about radiation damage response together with dissolution–precipitation or chemical exchange reactions with hydrothermal and low temperature fluids. Studies of radioactive minerals also include laboratory tests of chemical durability and the kinetics of structural recovery. Chemical durability studies can be further extended to include dissolution tests on irradiated and unirradiated synthetic material. In certain cases, the host rocks themselves, for example, uranium ore deposits, have been studied as analogs for spent nuclear fuel in geological repositories.

However, it is now increasingly clear that the wide variety of extant nuclear wastes will ensure that both glasses and ceramics will have very significant roles to play in the immobilization of nuclear wastes and thus confirm one of the criteria of sustainability for nuclear power production. Currently, hot isostatic pressing technology is making a strong impression as a very advantageous processing technique for the consolidation of ceramics and glass–ceramics for nuclear waste immobilization.
