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: Resistance to attack by halogens, oxygen and sulphur dioxide is ranked on a 4-point scale from 1 Unacceptable to 4 Excellent resistance. When setting constraints on a materials property during selection you can now view a 'guidance chart' that provides a quick visual indication of the range of possible values. Eco-Informed Material Choice, is a response to increasing eco-concerns. Chlorine is an intermediary in the production of PVC, chloroform and other polymers, paints and chemicals, in paper production.

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. When any metal with the exception of gold, platinum, and a few others that are even more expensive is exposed to air, an ultra-thin surface film of oxide forms on it immediately, following the oxidation reaction:.
These charts can be cut-and-pasted directly to reports and presentations. Some metals behave better than this.
CES EduPack 2009
Enhanced data on energy and CO 2 footprint New data on transparent plastics and elastomers In addition, new versions of a number of the databases available with specialist EduPack Editions have been released.
More on supporting textbooks. The new capabilities help teachers to identify and present key features of materials space. These include a new lecture on Bio Engineering, building on last year's release of the Bio Materials edupaco. 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 rapid oxidation.
Durability: gas attack – oxygen, halogens, sulphur dioxide
Industry solutions Industry overview Customer list Case studies. The film now coats the edupwck, separating the metal beneath from the oxygen. A white paper describing this information is available in the Information Pack.
T he film, once formed, separates the metal from the oxygen. Subsets can also be saved and then re-loaded and applied to a project. It introduces methods for thinking about and designing with materials when one of the objectives is to minimize environmental impact.
Both eupack corrode metals, damage concrete, and can attack some polymers. PTFE, Teflon and in the extraction of uranium. Chlorine, Cl 2made by the electrolysis of sodium chloride solution, is a powerful oxidizing agent. It is an intermediary in the manufacture of fluorocarbons e.

The subset can be defined and changed interactively during selection, greatly aiding the process of narrowing down material or processing options. 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. The film that develops on their surfaces is compact, coherent, and strongly bonded to the metal. It is widely used as a preservative for dried fruit, as an antioxidant in wine-making, as a bleach, and as a precursor in making sulphuric acid.
Resistance to attack by halogens, oxygen and sulphur dioxide is ranked on a 4-point scale from 1 Unacceptable to 4 Excellent resistance.
Chlorine is an intermediary in the production of PVC, chloroform and other polymers, paints and chemicals, in paper production. Sunlight can catalyze this reaction further to give sulphuric acid, H 2 SO 4. 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. At the end of each Science Note is a 'Further Reading' section providing references relating to the property being discussed.
It is one of the pollutants from coal-fired power stations responsible for acid rain. Notes attached to individual environments give more details. Resistance to gas attack is ranked on a 4-point scale from 1 Unacceptable to 4 Excellent resistance.
Polymers, too, oxidize, but in a more spectacular way. All products Product overview Arrange a demo.
