Communications revolution

The communications revolution also relies on a diverse set of CVD technologies. Some components are similar to those used in silicon microelectronics, but many are unique, involving complex epitaxial heterostructures of SiGe or compound semiconductor (e.g., AlGaAs) alloys that are required to yield high frequency (1-100 GHz) device operation. The communication revolution also relies on optoelectronic components, such as solid state diode lasers (another complex heterostructure device), and these devices are often grown by CVD. - Even the fiberoptic cables that transmit the optical component of the communications network are manufactured using a CVD technique to achieve the desired refractive index profile. ... 

Despite the electronic communications revolution, paper production continues to grow worldwide at a rate of 2% to 3% annually. Much of the incremental increase is based on pine because no other long-fibered softwood offers such high yield rates per hectare coupled with a short growth cycle. New kraft pine pulpmills and most existing mills will continue to practice tall oil recovery because non-removal of tall oil soap from kraft black liquor adversely affects evaporator and recovery boiler capacity (14). Increased tall oil production has been accompanied by new fractionator capacity in Europe and incremental expansion in the United States. Since the paper industry is the largest user of rosin size, it might be expected that the increased paper production would absorb the increased availability of tall oil rosin. 

Carbon materials always play a vital role in our lives mainly via innovative applications and origination of new materials [1-6] without which it is impossible to imagine our modem lives. AU the most significant milestones in the progression of our society are closely associated with advancement in the materials throughout the history [1, 2, 6]. For example, the Stone Age, Bronze Age, Iron Age, steel age (industrial revolution), silicon, and silica age (communication revolution). All these reflect that our modem civilization and daily life in the twenty-first century depends on an unlimited variety of materials of varying degrees of sophistication [2-6]. Thus, materials science plays a central role in our daily life. Therefore, materials are... 

The future demand for jet travel is veiy uncertain. Businesses have traditionally felt a need to travel for face-to-face meetings, hut the new communications technology revolution might in the future make business travel less necessaiy. However, any dropoff in business travel is likely to be replaced by growth in leisure travel as more affluent Americans decide to take more but shorter vacations, and fly for more weekend getaways. 

In today s world the decision is more complex. Markets are more sophisticated, skills can be in short supply, technological change can soon outdate newly installed processes, and there has been a phenomenal revolution in communications, both in terms of the physical movement of goods and people and of information around the world. As a consequence, companies often have to consider a wide number of options, and the eventual decision is based on optimizing the perceived net benefits. 

Popper s theory has been criticized by Thomas Kuhn (1962, 1969), who asserts that the development of science proceeds in revolutions hypotheses and theories are not refuted and replaced by new ones instead the scientific community will accept a new, more convincing, or better presented hypothesis without the old one having been disproved.

Chemistry really should be at the heart of this revolution in materials. Chemistry is the discipline that has been associated with the study of matter that is the science of chemistry. Moreover, chemistry is also the discipline associated with the purposeful manipulation of matter at the atomic and molecular level. But, in terms of materials chemistry, the time is right because of the ability to do analysis at an unprecedented level of resolution. However, our academic system has not yet responded for our students because our laboratory and lecture subjects have not yet included the dramatic advances in analytical capability. This is an important charge to the academic community.

The impact of this new technique, which was called Accelerator Mass Spectrometry (AMS), on the radiocarbon and archaeologist communities, was immediate and revolutionary. The introduction of AMS is indeed recognized by some as the third revolution in radiocarbon dating[22,23] and it has provided the opportunity to date very precious finds by collecting very small samples. The interest in developing the technique of AMS was so evident that, just few years after the measurements cited above, a first dedicated AMS system (based on a tandem accelerator) was designed and built [24] then, the first dedicated...
