New Concepts and Products

Furthermore, they show higher strength, stilfness and a significantly lower coefficient of expansion compared to purely used plastics. An increase in the wood percentage leads to efficient cost savings. Since, however, WPC is mainly 

In the United States, approximately 75% of the WPCs are used in the building sector and approximately 50% of the entire market volume is used for terraces and patios. In the year 2003, the market share of WPC products for exterior use was 14%, comprising a financial volume of approximately 3.5 billion US. These so-called deckings consist of polyethylene with a wood percentage of 50-70%. 

The annual growth of the markets is considerable. Worldwide, over 1 Mio mto of WPC are produced per year. While it is just under 1 Mio mto in Northern America, Europe has, with an estimated 105,000 mto (2006), still quite low values, followed by Asia with approximately 100,000 mto.  

The mechanical properties of Wood-Plastic-Composites substantially depend on the quality of the raw material, the composite and the manufacturing process. The density of WPC lies between 0.9 and 1.4 g cm and is higher than that of one of the two components, plastic and wood, alone. The porous wood structure is densified during the production process and plastics and additives partly penetrate into the cavities. Thus, water absorption is made harder, and the material swells less and more slowly.  

In general, the stiffness of a WPC increases linearly with increasing wood percentage. The stiffness of WPCs with a wood percentage of 50% is five times

This present English edition is not a direct translation of the Hungarian version. It has been thoroughly revised, principally because of the continuing rapid development of plastics. A couple of years is enough for the manufacture of a range of novel resins and products with markedly improved flammability characteristics. Brand-new concepts and products have appeared in the interval since the Hungarian edition was published, so that some chapters had to be completely re-written. The other chapters have also been carefully revised and supplemented as necessary. 

COST is a pan-European intergovernmental framework. Its mission is to enable breakthrough scientific and technological developments leading to new concepts and products and thereby contribute to strengthening Europe s research and innovation capacities.

Section I reviews the new concepts and applications of nanotechnology for catalysis. Chapter 1 provides an overview on how nanotechnology impacts catalyst preparation with more control of active sites, phases, and environment of actives sites. The values of catalysis in advancing development of nanotechnology where catalysts are used to facilitate the production of carbon nanotubes, and catalytic reactions to provide the driving force for motions in nano-machines are also reviewed. Chapter 2 investigates the role of oxide support materials in modifying the electronic stmcture at the surface of a metal, and discusses how metal surface structure and properties influence the reactivity at molecular level. Chapter 3 describes a nanomotor driven by catalysis of chemical reactions. 

In this project, you will be going through the design phase of product development. You are to create many new concepts and make a choice out of these. Some problems are more psychological than technical, but also this is part of product development. 

Natural product synthesis is the centerpiece of organic chemistry because it has always been the ultimate testing ground for new concepts and new synthetic methods.

Figure 0.1 Schematic of the principal ways in which science and engineering are practiced. Science proceeds mainly by induction from primitive concepts to general theories. From those generalities engineering proceeds by deduction to create new processes and products.

With Empower and its parent product Millennium, Waters is the pioneer for database-supported CDS. With the current version Empowers, the final stage of advancements is supposed to be reached. Currently, Waters is developing a successor called UNIEI that follows a new conception and a redevelopment from the scratch the combination of CDS, Electronic Lab Notebook (ELN), and Scientific Data Management System (SDMS).
