Hydrogen: the future energy carrier.
Since the beginning of the twenty-first century the limitations of the fossil age with regard to the continuing growth of energy demand, the peaking mining rate of oil, the growing impact of CO2 emissions on the environment and the dependency of the economy in the industrialized world on the availability of fossil fuels became very obvious. A major change in the energy economy from fossil energ...
متن کاملHydrogen: A Future Energy Carrier?
The world has a voracious appetite for energy. Abundant, inexpensive resources have fueled technological advances from the Industrial Revolution to the present. Continued growth will require a continued supply of inexpensive energy that is not sustainable with current resources. In addition, concerns about greenhouse-gas emissions from fossil-fuel sources are generating a new set of technologic...
متن کاملTribology in Total Hip Arthroplasty: Historical Development and Future Trends
Arthritis is a common disease in the elderly population. The most frequent treatment of arthritis is a total joint replacement. Approximatively 1.100.000 hip endoprostheses are implanted per year worldwide. This procedure is very successful in more than 90 % of the patients with good results after up to 10-year follow-ups. Unfortunately, due to the body’s reaction against the wear particles, th...
متن کاملTribology of Carbon-Based Coatings: Past, Present, and Future
During the last three decades, carbon-based coatings have enjoyed a growing interest in several industrial applications. By tuning the C sp-to-sp bonding ratio and by alloying the carbon with other elements, the researchers have been able to tailor unique physical, mechanical, and tribological properties in order to satisfy an increased technological demand. For instance, the low-friction coeff...
متن کاملPlanning for future energy resources.
WE AGREE WITH M. I. HOFFERT ET AL. (“Advanced technology paths to global climate stability: energy for a greenhouse planet,” Review, 1 Nov., p. 981) that stabilizing atmospheric CO2 concentrations at 550 parts per million (ppm) or below will require investment in energy research and development well in excess of current levels. However, their conclusion—that known technological options are not ...
