Major topics include health effects, exposures, and protective measures. Other educational concepts include internal radiation hazard, radon and its daughters/progeny.

Includes modules on Aluminum, steel, Transmission electron Microscopy, diffraction and solidification. http://www.merlot.org/merlot/viewMaterial.htm?id=594476 This film explores the health effects of ionizing radiation (radioactivity). The film also examines methods for reducing exposures to radiation in workplaces. Educational concepts include ionizing radiation, radiation sickness, radiation burns, other health effects, ion pairs, free radicals, penetration versus interaction, and time/distance/shielding.

Lectures provide a comparative examination of the origins of agriculture and the rise of early civilizations in the ancient Near East and Mesoamerica. The laboratory sessions provide practical experience in aspects of archaeological field methods and analytical techniques including the examination of stone, ceramic, and metal artifacts and bone materials. Lab sessions have occasional problem sets which are completed outside of class. http://www.merlot.org/merlot/viewMaterial.htm?id=86542 A weblog of news and views of interest to international community of Applied Mechanics, maintained by volunteers. http://www.merlot.org/merlot/viewMaterial.htm?id=76795 A basic on-line textbook covering Materials Science at the introductory college level. Also suitable for advanced high school level. Includes learning objectives, reviews and questions suitable for homework and exams. http://www.merlot.org/merlot/viewMaterial.htm?id=76109 Thermo_XP computes changes in path and state functions for user-selected ideal gas expansion (and compression) processes. The user selects from the following gas expansion processes: isothermal, isochoric, isobaric, adiabatic, or straight line on a P-V diagram. The user selects minimally-state-determining initial and final conditions for each process and the sink temperature. The application calculates the dependent state variables from the independent state variables of the user's choice. The application then computes work, heat, and changes in internal energy, enthalpy, and entropy. An animated graphic shows a thermally color coded gas in a piston-cylinder system with expansion correlated to a dynamic P-V, T-V, and q-V plot. If the user has selected an impossible process the user is user is prompted to change the sink temperature.The user may also select free expansion, maximum work, or half the maximum work be performed. Maximum work is automatically required for compression processes.Either British or Metric units may be selected as well as monotomic or diatomic gas. http://www.merlot.org/merlot/viewMaterial.htm?id=519777 Interactive case studies for students to work through online. Goes through a rational material selection process to find materials used in various applications (Oars, Wind Turbines, Tables, Springs, Pressure Vessels). Based on case studies created by Professor Mike Ashby of the University of Cambridge. Created by Granta Design with support from the UK Centre for Materials Education.Part of Granta's Teaching Resource Website http://teaching.grantadesign.com. http://www.merlot.org/merlot/viewMaterial.htm?id=82180 steeluniversity.org is an on-line initiative by the International Iron and Steel Institute (IISI) and is aimed at providing a comprehensive package of highly interactive e-learning resources on steel technologies, covering all aspects of the steelmaking processes through to products, their applications and recycling. The pilot project comprised two distinct, though related modules. The first is based on a typical steel application ? the car door outer panel. In this role-play simulation, the user is challenged to reduce the component mass by 25% without sacrificing performance. The second module puts the user in charge of a virtual secondary steelmaking plant in order to produce one of four steel grades used in very different applications (including car door outer panels). The underlying science is presented in supporting web pages and a PDF user guide. The two modules were completed in 2002 and extensively evaluated around the world, both in academia and within the steel industry. The evaluation of these pilot modules included an assessment of the support for the development of further modules. The response was overwhelmingly positive and has led to the IISI commissioning 20 further modules over the next four years.The pilot project comprised two distinct, though related modules.

This unique and popular course satisfies MIT's general chemistry degree requirement, with an emphasis on solid-state materials and their application to engineering systems. You'll begin with an exploration of the fundamental relationship between electronic structure, chemical bonding, and atomic order, then proceed to the chemical properties of "aggregates of molecules," including crystals, metals, glasses, semiconductors, solutions and acid-base equilibria, polymers, and biomaterials. Real-world examples are drawn from industrial practice (e.g. semiconductor manufacturing), energy generation and storage (e.g. automobile engines, lithium batteries), emerging technologies (e.g. photonic and biomedical devices), and the environmental impact of chemical processing (e.g. recycling glass, metal, and plastic).
