Consumers technologies

Electron microscopy is a very powerful technique for identifying the structure of self-assembly particles such as micelles exhibiting a typical size in the range of 5-20 nm or liposomes, which can be as large as several micrometers. However, it is a rather time-consuming technology, and care has to be taken for the interpretation of the results obtained. Compared to SAXS, electron microscopy allows analysis of much smaller volumes as well as visualizing structures of individual objects. 

The answer - and hence the challenge - is value driven innovation innovation driven by the changing environment, technological opportunity, and the consumer. Technology push will no longer suffice Innovation must be driven by consumer pull.

Although the proposed approadi is based on a quite demanding and time-consuming technology, so that the fabrication of broad-area devices is hindered, the EBL-based MEF strategy offers several interesting properties ... 

Other means for controlling sulphur emissions concern consumer technologies. 

Water With enough energy, wastewater can be reclaimed to drinking water standards by distillation, reverse osmosis, and other energy-consuming technologies, and seawater can be desalinated.

Nowadays, sensors find widespread use in many sectors, from traditional applications in research, to industrial production or environmental monitoring, to an increasing deployment in everyday life such as in vehicles, domotics, security, healthcare, or consumer technologies. 

In the future it will be difficult to avoid deterioration of certain characteristics such as viscosity, asphaltene and sediment contents, and cetane number. The users must employ more sophisticated technological means to obtain acceptable performance. Another approach could be to diversify the formulation of heavy fuel according to end use. Certain consuming plants require very high quality fuels while others can accept a lower quality. 

As PWB technology is refined to provide greater integration using finer conductor lines, there is renewed interest in hquid resists. The absence of a cover sheet and the abihty to apply thinner films both contribute to improved resolution and to an intrinsically lower consumables cost (16,17). 

In the late 1980s attempts were made in California to shift fuel use to methanol in order to capture the air quaHty benefits of the reduced photochemical reactivity of the emissions from methanol-fueled vehicles. Proposed legislation would mandate that some fraction of the sales of each vehicle manufacturer be capable of using methanol, and that fuel suppHers ensure that methanol was used in these vehicles. The legislation became a study of the California Advisory Board on Air QuaHty and Fuels. The report of the study recommended a broader approach to fuel quaHty and fuel choice that would define environmental objectives and allow the marketplace to determine which vehicle and fuel technologies were adequate to meet environmental objectives at lowest cost and maximum value to consumers. The report directed the California ARB to develop a regulatory approach that would preserve environmental objectives by using emissions standards that reflected the best potential of the cleanest fuels. 

In 1990, U.S. coke plants consumed 3.61 x 10 t of coal, or 4.4% of the total U.S. consumption of 8.12 x ICf t (6). Worldwide, roughly 400 coke oven batteries were in operation in 1988, consuming about 4.5 x 10 t of coal and producing 3.5 x 10 t metallurgical coke. Coke production is in a period of decline because of reduced demand for steel and increa sing use of technology for direct injection of coal into blast furnaces (7). The decline in coke production and trend away from recovery of coproducts is reflected in a 70—80% decline in volume of coal-tar chemicals since the 1970s. 

Resources of Sulfur. In most of the technologies employed to convert phosphate rock to phosphate fertilizer, sulfur, in the form of sulfuric acid, is vital. Treatment of rock with sulfuric acid is the procedure for producing ordinary superphosphate fertilizer, and treatment of rock using a higher proportion of sulfuric acid is the first step in the production of phosphoric acid, a production intermediate for most other phosphate fertilizers. Over 1.8 tons of sulfur is consumed by the world fertilizer industry for each ton of fertilizer phosphoms produced, ie, 0.8 t of sulfur for each ton of total 13.7 X 10 t of sulfur consumed in the United States for all purposes in 1991, 60% was for the production of phosphate fertilizers (109). Worldwide the percentage was probably even higher. 

Slow-Release Fertilizers. Products containing urea—formaldehyde are used to manufacture slow-release fertilisers. These products can be either soHds, Hquid concentrates, orHquid solutions. This market consumes almost 6% of the formaldehyde produced (115) (see Controlled release TECHNOLOGY, AGRICULTURAL). 

Estimates of the amount of natural gas available are made within the context of definitions and are subject to revision as definitions change, as additional information becomes available, as resources are consumed, or as undedyiag assumptions are altered. These definitions iaclude proved reserves where the resource is expected to be recoverable and marketable usiag known technology and prices probable reserves where a resource has been identified but not completely characterized and possible or potential gas where estimates are based on the available geological iaformation, historical trends, and previous successes. There are variations ia these definitions throughout the world.
