One example of this type of product innovation is the 3M Novec 1230 Fire Protection Fluid that was developed using a balanced lifecycle approach. Until the early 1990s, halon was used for critical fire protection applications (e.g., communications and electronic equipment). With the production of halons banned because of high ozone depletion potential and most of the halon replacement... 

We shall not elaborate on this topic here because the chemistry of the brain is scarcely known [15]. The brain processes the information and reacts accordingly, sending instructions through nerves and then transmitters produced by glands that link to the calcium network. It is also curious to note that the brain is immersed in a special protective fluid - the cerebrospinal fluid - the composition of which differs somewhat from the other external body biological fluids [7,15]. The form in which the human brain works requires a quite new approach to the use of energy and the environment in the chemistry associated with organisms.

If these first lines of defense are sufficiently stimulated or breached by an inhaled agent, the respiratory tract usually responds with the recruitment of additional phagocytic monocytes and neutrophils an increased output of protective fluids, cytokines, and mediators and for antigenic substances, the development of speciflc immunity. Most of these defense mechanisms are appropriate and protect the host from permanent injury, although the immune and inflammatory...

A varnish is often appHed on top of the paint layers. A varnish serves two purposes as a protective coating and also for an optical effect that enriches the colors of the painting. A traditional varnish consists of a natural plant resin dissolved or fused in a Hquid for appHcation to the surface (see Resins, natural). There are two types of varnish resins hard ones, the most important of which is copal, and soft ones, notably dammar and mastic. The hard resins are fossil, and to convert these to a fluid state, they are fused in oil at high temperature. The soft resins dissolve in organic solvents, eg, turpentine. The natural resin varnishes discolor over time and also become less soluble, making removal in case of failure more difficult (see Paint and FINNISH removers). Thus the use of more stable synthetic resins, such as certain methacrylates and cycHc ketone resins, has become quite common, especially in conservation practice. 

Gels. Fluorosihcone fluids with vinyl functionahty can be cured using the platinum catalyst addition reactions. The cure can be controlled such that a gel or a soft, clear, jelly-like form is achieved. Gels with low (12% after 7 d) swell in gasoline fuel are useflil (9) to protect electronics or circuitry from dust, dirt, fuels, and solvents in both hot (up to 150°C) and cold (down to —65° C) environments. Apphcations include automotive, aerospace, and electronic industries, where harsh fuel—solvent conditions exist while performance requirements remain high. 

Vegetable and seed oils as well as some synthetic base stocks present a new class of biodegradable base stocks. These fluids (10) have excellent biodegradation properties as measured by criteria developed by the Environmental Protection Agency (EPA) or Organization of Economic Cooperation and Development (OECD). OECD 301 and EPA 560/6-82-003 measure the biodegradation of lubricants. These tests were developed to measure the degradation of oil, especially two-cycle ok, on waterways. Aquatic toxicity criteria toward fish is also found to be acceptable for this class of fluids as measured by EPA 560/6-82-002 and OECD 203 1-12.
