Either way, damage accumulates. The driving force is the free energy of oxidation, but the rate of oxidation is limited by the rate of diffusion, and the thicker the film, the longer this takes. This makes it simple to quickly create charts displaying only the materials covered in your course, and to set up specific student exercises or lecture demonstrations. The most stable state of most elements is as an oxide of some sort. More on supporting textbooks.

Use these slide sets, or parts of them, to enhance or support your own lectures. These charts can be cut-and-pasted directly to reports and presentations.
CES EduPack 2009
Durability information has been significantly enhanced at level 2 of the EduPack Materials and Processes Database the level designed for intermediate-level students. For these the weight gain is parabolic, slowing up with time, and this implies an oxidation rate with the form:.
The tool has been widely used, well-received and, based on feedback, updated in this release. The new capabilities help teachers to identify and present key features of materials space. Chlorine, Cl 2made ces edupack 2009 the electrolysis of sodium chloride solution, is a powerful oxidizing agent.
Many of you used it, liked it, and provided useful feedback, which has been used to create an improved version. If the reaction is to go further, oxygen must get cew the film.
This is because the oxide film cracks and, when thick, spalls off and does not protecting the underlying metal. New and updated level 3 data The advanced property data at level 3 of the Materials and Process Database has been updated and extended in areas including: In contact with water it is hydrolyzed to sulphurous acid:. Sunlight can catalyze this reaction further to give ces edupack 2009 acid, H 2 SO 4.
As storage technology adapts to changing HPC workloads, Robert Roe looks at the technologies that could help to enhance performance and accessibility of storage in HPC. At the end of each Science Note edpuack a ‘Further Reading’ section providing references relating to the property being discussed.
Durability: gas attack – oxygen, halogens, sulphur dioxide
Create custom subsets You can quickly and easily specify a custom subset of materials from the database for use during a selection project. Durability information Durability information has been significantly enhanced at level 2 of the EduPack Materials and Processes Database the level designed for intermediate-level students.
The new version includes many enhancements based on user feedback, improving its practicality and value:. Advanced teaching Research Industrial data How do I get it? This new tool for introducing eco design rdupack was released last year and has since been widely applied.

The advanced property data at level 3 of the Materials and Process Database has been updated and extended in areas including:. Fluorine, F 2like chlorine, is a powerful oxidizing agent, essential as an etchant in the production of semiconductors, displays, and in MEMS manufacture.
These features help to make the EduPack property charts even more informative. Ces edupack 2009, Simulation and Modelling. The driving force for a material to oxidize is its free energy of oxidation — the energy released when it reacts with oxygen, but a big driving force does not necessarily mean ces edupack 2009 oxidation.
CES EduPack combines comprehensive materials information, specialist software to access and use that information, and an extensive series of supplementary teaching resources.
Other new features include data on durability, enhanced materials selection, charting and presentation improvements, updated PowerPoint lectures, and references to a wider range of standard materials textbooks. Fluorine is highly reactive, sufficiently so that many organic materials and some metals ignite spontaneously in its presence:. Simulating the future of cycling.

For some metals the edupsck gain is linear, and this implies that the oxidation is progressing at a constant rate:. It is widely used as a bleach, in the production of insecticides, and to purify water supplies. Notes attached to individual environments give more details. By using simulation software, road bike manufacturers can deliver higher performance products in less time and at a lower cost than previously achievable, as Keely Portway discovers. To react further either oxygen atoms must diffuse inward through the film to reach the metal or cs atoms must diffuse outward through the film to reach ces edupack 2009 oxygen.
Enhanced Eco Audit Tool This new tool for introducing eco design concepts was released last year and has since been widely applied.
