The isolation of stem cells begins by first determining the source of the cell. Embryonic tissues will yield the greatest quantities of stem cells, since they are composed almost purely of such...

Stem cell research is a contentious topic among scientists, politicians and religious leaders, and the scope of research is often hampered by legislation and conflicting moral convictions. The...

Photovoltaic cells harness one of the oldest and rawest forms of energy available to us: solar power. However, many questions about photovoltaic cells still linger because the solar energy market...

Solar cells are used as a means to produce energy utilizing a renewable resource---the sun---rather than depending on less eco-friendly methods, such as burning fossil fuels. The growing interest...

Solar cell technology offers a wide array of options which allow you to collect clean, renewable solar energy and convert it to power. You can use solar energy to replace some of the electricity...

Solar cells are used in solar panels to change solar energy into electricity. Often called photovoltaic technology, the energy acquired from solar cells is a viable source of clean, alternative...

Solar cells are devices which convert sunlight directly into electricity. The solar photovoltaic (PV) cells, when assembled together in clusters, form the solar panels. These cells capture the...

Hair is almost 91 percent protein, made strong by its composition of amino acids. Hair is a living, growing part of the body, although the portions that appear above the skin have already died....

Photovoltaic cell, the basic unit of solar power modules, are made of a silicon-based material that absorbs sunlight. These cells are relatively small, with diameters between one and 10...

Hydrogen fuel in cars can greatly reduce our dependence on foreign oil, as well as reduce the carbon footprint left by gas-burning vehicles. Another great benefit of hydrogen fuel is that it can...

Screen print solar cells are a special type of solar cell that uses nanoparticles to trap the energy in the sun's rays, instead of using silicone-based photovoltaic cells. Nanoparticles are...

It may shock you to learn that the average American eats up to three pounds of sugar every week. That's the equivalent of three full bags of the stuff. Of course, few people actually go through...
