Lithium-Ion Cells. Lithium-ion cells and the newer alternative, lithium-ion-polymer, can usually run much longer on a charge than comparable-size Nicad and nickel-metal hydride batteries. Usually is the keyword here since it depends on the battery s application. If the product using the battery requires low levels of sustained current, the lithium battery will perform very well however, for high-power technology, lithium cells do not perform as well as Nicad or nickel-metal hydride batteries. 

Fluid power systems have developed rapidly over the past thirty-five years. Today, fluid power technology is used in every phase of human existence. The extensive use of hydraulics to transmit power is due the fact that properly constmcted fluid power systems possess a number of favorable characteristics. They eliminate the need for complicated systems of gears, cams, and levers. Motion can be transmitted without the slack or mechanical looseness inherent in the use of solid machine parts. The fluids used are not subject to breakage as are mechanical parts, and the mechanisms are not subjected to great wear.

The continual development and evolution of novel and powerful technologies has allowed scientists to answer increasingly complex questions about the basic mechanisms underlying cellular homeostasis for the benefit of human health. Our understanding of how cells proliferate, thrive, adapt, and die in response to numerous environmental...

A 250 kilowatt atmospheric system is planned for a Toronto, Ontario, Canada site. The system will be operated by Ontario Power Technologies (formerly Ontario Hydro). The unit will supply 145 kilowatts of heat to the site heating system. Electric efficiency is expected to be about 47% (LHV). Operation of the combined heat and power system is expected in late 2001.

Adsorptive separation is a powerful technology in industrial separations. In many cases, adsorption is the only technology available to separate products from industrial process streams when other conventional separation tools fail, such as distillation, absorption, membrane, crystallization and extraction. Itis also demonstrated that zeolites are unique as an adsorbent in adsorptive separation processes. This is because zeolites are crystalline soUds that are composed of many framework structures. Zeolites also have uniform pore openings, ion exchange abiUty and a variety of chemical compositions and crystal particle sizes. With the features mentioned, the degree of zeoUte adsorption is almost infinite. It is also noted that because of the unique characteristics of zeoHtes, such as various pore openings, chemical compositions and structures, many adsorption mechanisms are in existence and are practiced commercially. 

When we have a powerful technology that can make a material with interesting properties, and we can keep out competition for a while with unique technology and patents, we ask which market will appreciate a material with these properties. An ideal market is also one where the potential buyers are numerous and affluent, where this material will help them to fulfill one or more significant needs, where there are no very satisfactory competitive products, where there are no threats to safety and the environment, and where it can be manufactured and make a good profit. What is the search engine that can systematically discover many or all of the major potential markets Let us look at the historic cases mentioned in Chapters 1 and 2. 

Any powerful technology has two faces. In fact, the adverse connotations of nuclear power (e.g. atomic bombs, radioactive pollution) are offset by important positive applications (e.g. in nuclear medicine). Sensors have two opposing faces as well. On the one hand, they make a major choice for the Analytical Chemistry of the XXI century on the other, the ease with which they can output signals (and hence results) may induce careless (non-contrasted) use and obtainment of spurious analytical information, particularly in the hand of non-experts (e.g. physicians, engineers) obviously lacking... 

With ever more powerful technology becoming available, computer-based molecular modeling of complex chemical reactions is now commonplace. But while the Diels-Alder reaction has received a great deal of theoretical attention, the dipolar cycloaddition reactions of nitrones were until very recently relatively...

The aclinide elements are a group of chemically similar elements with atomic numbers 89 through 103, and their names, symbols, and atomic numbers are given in Table 1, see also Radioactivity Nuclear Power Technology Plutonium Thorium and Uranium. Each of the elements has a number of isotopes, all radioactive and some of which can be obtained in isotopically pure form.
