Radiation damage in nanostructured materials

RADiATiON DAMAGE TO MATERIALS

OBJECTIVES: After completing this module you will be able to: Explain why ionizing radiation has little effect on metals and their mechanical properties. but creates significant damage in non-metals. 4.2 a) Describe the damage created in metals by fast neutrons. b) Explain how this damage affects: strength, hardness and ductility. 4.3 Explain why elevated operating temperatures reduce the effec...

Radiation Damage in Polarized Target Materials*

We examine some of the parameters which influence the decay of the polarization of polarized targets in an intense proton beam. We find that the usual characteristic flux for the polarization to drop to 1/e of its initial value does not provide a sufficient criterion to specify the radiation resistance of target materials. We give a more detailed method of evaluation including an empirical form...

Thermal Transport in Nanostructured Materials

A detailed understanding of thermal transport at the nanoscale is becoming increasingly needed. This need is largely being driven by two distinct technological challenges. First, continuous miniaturization of electronic devices and the ever-increasing density of the components on integrated circuits (ICs) place ever-increasing thermal loads on systems. Indeed, it is now necessary to make therma...

Functional Nanostructured Molecular Materials

The Electrochemical Society Interface • Fall 2001 here has been tremendous recent interest in the design and assembly of porous nanostructured materials.1 Synthetic approaches range from coordination-polymer formation to surfactant-templated alumino-silicate growth to semiconductor nanoparticle aggregation, while functions include chemical catalysis, chemical sensing, energy storage, and energy...
