Silver Nanoparticles: A Valuable Weapon in Microbial Warfare

2017-11-11T17:33:34-08:00 December 4th, 2011|Biomedical Engineering, Electrical Engineering, Environmental Engineering, Issue III, Material Science, Volume XIII|

Nanotechnology is currently being used as a valuable weapon for combating body odor-causing bacteria. Materials can be manufactured at the ‘nano’ scale, one billion times smaller than the world of meters we currently live in. Nanoparticles provide terrific driving forces for diffusion, which allows chemical reactions to occur at a high rate. In the case [...]

Better Illuminating our Lives: The Need and Implementation of a Smart Grid

2017-11-11T17:12:02-08:00 February 20th, 2010|Energy & Sustainability, Environmental Engineering, Issue I, Volume XIII|

The demand for power in the United States is rising every year, mostly due to population growth and the increasing use of and dependence on electronics. Our current power grid, being nearly a century old, is simply struggling to keep up. The development of a Smart Grid is a necessary improvement for this country’s infrastructure [...]

California’s Water Crisis

2017-11-12T22:46:17-08:00 October 1st, 2009|Civil Engineering, Energy & Sustainability, Environmental Engineering, Issue II, Issue III, Volume XII|

With its naturally arid landscape, Southern California has always relied on water piped in from other locations in order to meets its demand. However, a growing population and dwindling supplies are creating a huge water deficiency. Traditional methods of tapping into new surface or groundwater sources have proven to be very detrimental to the environment, [...]

Engineering Water: Finding Solutions to a Drying Well

2018-11-07T10:37:58-08:00 September 1st, 2004|Energy & Sustainability, Environmental Engineering, Issue II, Volume VI|

The global fresh water supply has become a major concern as most third world nations, and even some developed countries, face the disconcerting reality that drinkable water is running out. To solve this newly realized crisis, engineers are offering the world new, innovative techniques for water purification. Nanotechnology, technological development on the nanometer scale, is [...]

Wastewater Technology: Engineering a Healthier Society

2019-01-10T11:08:00-08:00 May 3rd, 2003|Biomedical Engineering, Civil Engineering, Environmental Engineering, Issue II, Volume V|

Long before the age of computers, light bulbs, automobiles, or locomotives, a revolutionary feat in engineering transformed society. This technology almost singly separates developed countries from their developing counterparts, and many Americans take it for granted. Rarely do we ever think about it when we use it, and when we do, it's generally because it [...]

Phytoremediation

2019-01-10T11:09:39-08:00 May 3rd, 2003|Chemical Engineering, Energy & Sustainability, Environmental Engineering, Issue II, Volume V|

The natural environment is very easily polluted by the toxic compounds contained in oil. In the past, methods for restoring contaminated areas have been expensive but largely inadequate. A recently developed decontamination process called phytoremediation uses plants along with the bacteria that live in their roots to break down the toxins directly, or to absorb [...]
