    research-on-gas-from-grasTurn straw into gold. Such stuff can only be see in fairy tales. Today, a group of scientist is trying to turn straw into consumable energy.

    The experts make use of a nanocatalyst to perform this modern-day magic. The particle that stirs up the process has some particles of gold on the surface of the titatium-oxide. The combination of these materials are quite strong to break bonds between molecules of oxygen and between molecules of acetic acid. A few technical terms after and you will get ethanol, an important precursor to produce viable fuel.

    Because of its ability to break bonds between molecules, the nanocatalyst is being looked at as one of the best candidates to be used in industrial applications for the production of clean energy. One of the proponents explained that the nanoparticles have very high activity during various reactions.

    In order to look into the possibilities, the team from the University of Virginia combines lab experiments with computer simulations. Through their work, they saw a reaction site on the gold-titanium complex that is pretty much like catalysis.

    The earlier part of the study made the scientist think that it was only the gold that was active during the reactions they saw. Recently though they realized that the oxides also play a very important role in the process. They create the site where the most important reactions can take place.

    Experts say that oil will be more expensive in the future and the only way out for us will be to do biomass conversion. Scientists need to find efficient ways to make biofuels affordable and having better catalysts will make the process a lot easier.

    The simulations on computers for the gold-titanium oxide catalyst is just a start of something big. If it ever leads to producing gases from the grasses, this will lead to more sustainable fuels that are available to the masses.

    A deep ocean current covering that has a volume of 40 Amazon Rivers was discovered by Japanese Australian researchers. The current is said to be located near the Kerguelen Plateau in the Indian Ocean, a sector of the Southern Ocean. The spot is 4,200 kilometers south-west from Perth, Australia.

    Kerguelen PlateauThe researchers described this current in a paper published online called the Nature Geoscience. According to their report, the current is more than three kilometers below the ocean’s surface. This current stands in the pathway of the Earth’s network of global current, and can strongly influence climate patterns.

    It was also reported that the current carries dense, oxygen-rich water, which provides levels of oxygen to the deep waters of Antartica. Without this supply, there could be very low levels of oxygen in the deep sea. Dr. Steve Rintoul, the co-author of Antartic Climate and Ecosystems, also explained how the ocean affects climate change.

    Apparently, the more the ocean transports and stores heat and carbon dioxide, the slower the process of climate change becomes. This particular current which was spotted in the Kerguelen Plateau, is an important part of the global network of ocean currents that are also referred to as the “overturning circulation”. They determine just how much carbon dioxide and heat the ocean can still soak up.
