Dispersar o Calor como nunca antes, com Nanoestruturas:

Nanostructure coatings remove heat four times faster

In a finding that could well revolutionize cooling technology as we know it, researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a way to achieve near-optimal heat dissipation by applying a nanostructured coating. Because of performance, versatility and economy of materials used, their method could soon lead to better electronics, heating and air conditioning.

We've recently discussed the importance of heat dissipation in electronics; however, while cooling laptops and the likes is an important issue in itself, they are by no means the only area that could benefit from better heat dissipation. The team's work focuses on heat transfer using water in particular and could be used in heating, cooling and air conditioning applications as well as keeping your lap from burning up the next time you check your email at the airport.

Fungus Among Us Could Become Non-Food Source For Biodiesel Production

In the quest for alternatives to soybeans, palm, and other edible oilseed plants as sources for biodiesel production, enter an unlikely new candidate: A fungus, or mold, that produces and socks away large amounts of oils that are suitable for low-cost, eco-friendly biodiesel. That's the topic of a study in ACS' bi-monthly journal Energy and Fuels.

Victoriano Garre and colleagues point out that manufacturers usually produce biodiesel fuel from plant oils - such as rapeseed, palm, and soy. However, expanded production from those sources could foster shortages that mean rising food prices.

In addition, oilseeds require scare farmland, and costly fertilizers and pesticides. To meet growing demand for biodiesel fuel, scientists are looking for oil sources other than plants. Microorganisms such as fungi, which take little space to grow, are ideal candidates. But scientists first must find fungi that produce larger amounts of oil.
