Table 8.2 Some Internet Material Property Databases...

This report is intended for busy specialists of various kinds (both technical and commercial) who need to strengthen or update their imderstanding of the wider additives scene. The Internet is widely thought to provide all the information needed in this and many other fields, but the time taken to search himdreds of complex websites is rarely costed. When the time factor is coupled with the obvious commercial self-interest motivating many writers of Internet material, an objective and independent smnmaiy of the subject appears cost-effective in the long term. 

A large amount of information can be provided on a technical service Internet site by means of hyperlinks, ie, cHckable terms or addresses that allow the reader to access multiple layers of information by a simple cHck of a control device. Some companies have provided their entire Hbrary of open Hterature on their products ia the form of material stored within a hypedinked page. The reader can either browse this information directly on the site or download it to their own computer to be read at their convenience. 

The definition of a drug differs between dictionaries and among the various professional specialisms. A search of the internet elicited various definitions and a paraphrase of the most memorable is a compound can be defined as a drug if, when injected into a rodent, it yields a scientific publication . Although this is a memorable definition, for the purposes of this review, however, a drug is defined broadly as a compound that has properties that influence the health of an animal when ingested or administered to that animal. A brief look at current literature will quickly convince the reader that this is a definition which covers man-made and natural compounds that can be extracted from plant material and microbes and iised. ... 

To help the reader keep abreast of these advances we present a list of useful WWW sites in this appendix. Realistically, this list should be updated on a daily basis as many of the tools offered on the Internet are made available not only by large organizations and research groups but also by individual researchers. The goal, therefore, has not been to provide a nearly complete guide to the WWW but rather to provide material representative of the tools useful to researchers in the fields of biochemistry and biophysics. 

In addition to printed compilations, more and more of the information is available on CD-ROM and latterly also on-line on the internet. This last is a feature of the service provided by MSI, Materials Science International Services in Stuttgart. This organisation, under the working name of MSIT Workplace (http //www.msiwp.com), provides information on the entire corpus of phase diagram compilations. 

This chapter has only scratched the surface of the multitude of databases and data reviews that are now available. For instance, more than 100 materials databases of many kinds are listed by Wawrousek et al. (1989), in an article published by one of the major repositories of such databases. More and more of them are accessible via the internet. The most comprehensive recent overview of Electronic access to factual materials information the state of the art is by Westbrook et al. (1995), This highly informative essay includes a taxonomy of materials information , focusing on the many different property considerations and property types which an investigator can be concerned with. Special attention is paid to mechanical properties. The authors focus also on the quality and relutbility of data, quality of source, reproducibility, evaluation status, etc., all come into this, and alarmingly. 

Here s some library or Internet work for you. Compile a table of values on the porosity of common materials (e.g., soils, clay, glass beads, crushed stone, charcoal, other materials). Or if you are really ambitious, apply the equations provided in this chapter along with physical properties data obtained from your search and estimate the porosities.

These faetors are attributed to bateh and semi-bateh proeesses rather than eontinuous proeesses. However, the use of eontinuous proeesses on fine ehemieal manufaeturing sites is limited. It is often preferable to use the semi-bateh mode as opposed to bateh proeesses. The Appendix lists hazards of pertinent ehemieal reaetions for toxie and reaetive hazards ehemieals. Information eoneerning the safety of various ehemieals (e.g., ammonia and others) ean be readily obtained from the World Wide Web. Table 12-1 shows how to aeeess a material safety data sheet at the Vermont Safety Information (VIRI) site on the Internet.

MCBase offers the possibility to load the original CAMPUS data of different suppliers from version 3.0 and higher into one database, which allows direct comparison. It has been developed in close cooperation with the CAMPUS consortium. For more information see http //www.m-base.de/. MCBase is user friendly and offers extremely efficient handling of material data. All CAMPUS options are available define search profiles define and sort tables print tables and data sheets curve overlay scatter plots. In addition MCBase 4.1 offers search in curves search for comparable grades text search update via Internet calculation of simulation parameters. A French version of MCBase is available from the distribution agent in France. 

The Japanese Plastic Waste Management Institute is developing a process to convert PVC and other plastic waste materials to fuel oil through pyrolysis. In Eiuope, a free market for plastics waste is now being established by the European Plastics Converters over the internet. The company says it will be possible to establish market prices for recyclates at European level on a supply and demand basis. The European market for recycled plastics is currently worth around 1.18bn US dollars and is predicted to reach 2.53bn US dollars by the endof2001. WORLD...

In the descriptive domain, the material offered by the numerous data banks, by researching the internet, and that available arising from the obligations on suppliers to provide freely complete safety publications for the user (but which are sometimes open to criticism, as in this book) makes it, it seems to me, superfluous to offer yet another similar contribution of that kind. 

Greater co-operation among producers could be developed. The World Wide Web has provided a model of sharing information based on very clear technical principles and formats, but with no formal bureaucracy or external control. Researchers using the Web can move easily among computers of many research institutions that are linked to the Internet. Perhaps the National Measurement Institutions that produce RM could make their instruments and laboratories just as open and available to researchers who are characterizing a new material (Rasberry 1998). 

Many substances must have Material Safety Data Sheets (MSDS) to describe their hazards and methods to correctly handle the substance. Using an internet search engine, find the primary health risk associated with argon, a noble gas. 

A limited number of copies of this report are available from the National Materials Advisory Board, 500 Fifth Street, N.W., Keck WS932, Washington, DC 20001 (202) 334-3505 or (202) 334-3718 Internet, http //www.nas.edu/nmab. 

Physico-chemical instrumental analysis nowadays has greatly suppressed such chemical handwork. An internet website disseminates methods of analysis and supporting spectroscopic information on monomers and additives used for food contact materials (principally packaging).
