Union Chimique Beige was founded in 1928 by, among others, Baron Emmanuel Janssen, who was married to a granddaughter of Ernest Solvay, the founder of Sol-vay, the other Belgian hybrid chemical/pharmaceutical company. At that time, Union Chimique Beige was producing several heavy chemical intermediates such as ammonia, sulfuric acid, sodium sulfide, and coal derivatives. 

Over the last two years, UCB has gone through a tremendous transition from a hybrid chemical/pharmaceutical company to a pure bio-pharmaceutical player.

Hoechst transformed its business from a hybrid chemical company into a pure Hfe science company by radically divesting over 80 percent of its portfolio, getting rid of businesses such as specialty chemicals (sold to Clariant) or chemical intermediates (spun off into Celanese). It completed the acquisition of Roussel-Uclaf and bought Marion MerreU Dow, and finally merged with the French life science company Rhone-Poulenc after the latter had also spun off aU its chemical business as Rhodia. By reinventing" itself under the brand name Aventis, it increased its Return on Sales (ROS) from 4.6 percent to 12.4 percent, a development that has recently been viewed very favorably by capital markets. 

So far, fitted kinetic odes have been less successful than reduced mechanisms. One reason for this limited success may be a result of the hybrid chemical-mathematical approach for finding the ode models. It is expected that in the future, fully mathematical methods will be used for finding... 

It can be seen from the structure of the glycol ethers (Figure 13.4) that if the alkyl chain is extended sufficiently then it begins to approximate the structure of simple nonionic surfactants, those of the ethoxylated alcohol family. This has led some chemical producers in recent times to introduce compounds meant to be hybrid chemicals with the properties of both solvent and surfactant. They are not at present used to any great extent in household cleaners, but remain a possibility for future formulations. 

Earlier than with pulsed chemical lasers, the first technological breakthrough in chemical lasers occurred for continuous-wave lasers. Almost simultaneously in 1968 two groups successfully operated continuous-wave chemical lasers. One was at the Aerospace Corporation headed by T. A. Jacobs 75>, the other one at Cornell University under T. A. Cool 76>. One of these lasers was an HF laser the other was that is now called a hybrid chemical laser, being pumped by energy transfer rather than by a direct chemical reaction. This laser principle has been described in the context of pulsed chemical lasers in Section 6.5, In addition to these devices, an HF cw laser having millisecond flow duration was also demonstrated in principle in a shock tunnel. The latter employed diffusion of HC1 into a supersonic stream containing F atoms 77>.

Silanes and other coupling agents can be applied to various substrates or incorporated into an adhesive/primer to serve as hybrid chemical bridges to increase the bonding between organic adhesive and inorganic adherend surfaces [97-100]. Such bonding...

The dispersion levels of the clay platelets helps in retaining the viscosity both at lower and higher temperatures. The anisotropy and small size prevent free rotation of the clay platelets and increases the viscosity. In addition to this, in in-situ clay-polymer hybrid, chemical bonding between the s-caprolactum and oigano-ions of clay platelets is the reason for the higher viscosity than the melt-blended system, where only physical interaction occurs. 

MOFs have emerged as a novel class of porous solid-state materials with hybrid chemical composition of organic molecules bearing a wide array of functional groups capable of metal coordination and/or chelation and metal ions/clusters. Several attributes of such materials have captured the interest of scientists in academia and industry because of the wide potential applications in current demanding technologies. MOF attributes are directly correlated to the tunable hybrid chemical composition, crystallinity, and modular nature. 

This approach marked the hybridization of two types of materials known previously in solid-state chemistry, zeolites, and MOFs, and hence the term ZMOF was introduced to designate materials with hybrid chemical composition and zeoUtic topologies (Figure 27). 

When displacement reactions are associated with electroless deposition of silver, exotic coaxially-organized heterostructures, characterized by hybrid chemical compositions, are generated [17, 125]. The heterostructures present a concentric topology of the various metals, a sort of Matrioshka arrangement known as nanorattles as defined by the same authors [17], Different shape and material configurations have been reported in literature, for instance onto spherical AuAg alloy core NCs, Ag could be deposited by chemical reduction promoted by ascorbic acid at high temperatures and water environment, afterwards, a redox displacement HAuCU-promoted altered the silver shell composition...

The hybrid chemically etched/plate formed fin configuration is a three pass cross counter flow design. The core is vacuum brazed and consists of chemically etched water layers, closure bars, formed gas fins, parting sheets, and end sheets. Headers and mounting brackets are welded onto the core. This design was evaluated for three materials, titanium CP-70, stainless steel 347, and nickel alloy 625.
