The extraction of toxic but valuable metals such as nickel, chromium, lead, and mercury, from wastewaters produced in various industries such as semiconductor and mining has been a serious challenge to these industries.
Unlike the commonly used ion-exchange resins that...
Micro combined generation of heat and power (CHP) have been added to the qualities of fuel cells. These smaller scale CHPs can be used as a replacement of conventional household boilers or as an addition to gas and heating...
The general public may be only be familiar with carbon-dioxide as a greenhouse gas , but GHGs include many more gases, including naturally occurring water vapor , ozone , nitrous oxide , and methane .
While naturally occurring in...
What is the point of biofuels development, except to eliminate carbon-dioxide emissions? Basically speaking, biofuels emit the same amount of CO2 during combustion that was removed from the atmosphere by the biomass it was synthesized from.
For example, a...
Most of the emphasis of biofuel synthesis has been on carbon-neutral programs. Put simply, the amount of carbon-dioxide removed from the atmosphere, by the biomass crops, is equal to the amount of CO2 emitted by biofuel synthesis and...
Years after attempting to decrease the reflectivity of solar cells even further, Natcore has finally came up with its ‘blackest’ solar cell to date, reflecting only 0.3% of incident of sunlight, without the use of an antireflective coating, but...
Cities are always evolving, often out with the old and in with the new. Some old things are restored, while others are razed and make way for highways with increased traffic capacity, or high-rise office buildings. This seems to...
There aren't too many things that we bought in 1980 that are still functioning just as they were when new, much less in existence. This might be a good time to check your warranty, if you still have something...
As the demand for imported oil continues to drop, new technology and methods are enabling oil drillers in the US to extract more oil from its own territories. In 2006, the US imported 60% of its oil needs, but...
Charging electrical vehicles wirelessly is now possible, according to Canadian researchers. Although there are some concerns about unknown health risks on humans that might be caused by high power and high frequency electromagnetic fields, Professor Lorne Whitehead from University...
