Bioplastic bottles also keep cooking oil fresh for a long time

No transfer of compounds from the bottle material into the oil detected

22-Feb-2023 - Bottles made of bioplastic protect cooking oil from oxidative spoilage (rancidity) to a similar extent as PET bottles. In addition, even less taste- and odor-impairing substances were formed. This is the result of a recent study published in the journal "Food Packaging and Shelf Life" by ...

Nanotracer tester tells about wells

Rice University lab builds rig to evaluate oil, gas wells in fracturing operations

26-Feb-2014 - A tabletop device invented at Rice University can tell how efficiently a nanoparticle would travel through a well and may provide a wealth of information for oil and gas producers. The device gathers data on how tracers – microscopic particles that can be pumped into and recovered from wells – ...

Deepwater Horizon: Identifying harmful elements of persisting oil

24-Jan-2014 - On 20 April 2010, a floating oil rig in the Gulf of Mexico called Deepwater Horizon suddenly exploded, leading to the largest accidental marine oil disaster in the world. Collaborating scientists at EPFL in Switzerland and the Woods Hole Oceanographic Institution (WHOI) in the United States have ...

Explanation for strange magnetic behavior

Discovery could one day lead to electronic materials that provide both computation and data storage

27-Aug-2013 - They're not exactly the peanut butter and jelly of semiconductors, but when you put them together, something magical happens. Alone, neither lanthanum aluminate nor strontium titanate exhibit any particularly notable properties. But when they are layered together, they become not only conductive, ...

MIT researchers show silicon can be made to melt in reverse

Material that shows melting while cooling could lead to applications in solar cells, other devices

06-Aug-2010 - Like an ice cube on a warm day, most materials melt — that is, change from a solid to a liquid state — as they get warmer. But a few oddball materials do the reverse: They melt as they get cooler. Now a team of researchers at MIT has found that silicon, the most widely used material for computer ...

Hydrogen causes metal to break

05-Aug-2010 - Hydrogen is considered the fuel of the future. Yet this lightest of the chemical elements can embrittle the metals used in vehicle engineering. The result: components suddenly malfunction and break. A new special laboratory is aiding researchers’ search for hydrogen-compatible metals. Most ...

Waste chip fat fuels hydrogen economy

29-Jul-2010 - Don't pour that dirty fat from the frier down the sink – it could be used to make the fuel of the future. Hydrogen has been tipped as a cleaner, greener alternative to fossil fuels. But scientists have struggled to find a way to make it that doesn't consume vast amounts of energy, use up scarce ...

Molecules typically found in blue jean and ink dyes may lead to more efficient solar cells

02-Jul-2010 - Making better solar cells: Cornell University researchers have discovered a simple process - employing molecules typically used in blue jean and ink dyes - for building an organic framework that could lead to economical, flexible and versatile solar cells. The discovery is reported in the journal ...

Physicists' findings about helium could lead to more accurate temperature

20-May-2010 - In the May 7 edition of Physical Review Letters an international team led by University of Delaware researchers reports new findings about helium that may lead to more accurate standards for how temperature and pressure are measured. In the article the scientists provide a new theoretical ...

Nanocapsules for artificial photosynthesis

10-Nov-2009 - Imitating photosynthesis in plants? If we were to accomplish this, mankind would have a little less to worry about. Chemists from the University of Würzburg have now made progress on the road to achieving artificial photosynthesis. The structure that has been developed in the university's ...
