- Delft researchers predict 'nanobattery' performance
04-02-2007 · EurekAlert!
Researchers at Delft University of Technology can predict how nanostructuring -- the extreme reduction of structure -- will affect the performance of Li-ion batteries. The nanostructuring of battery materials is likely to be common practice in the future, but it is not always performance enhancing. The research findings have recently been published in the Journal of the American Chemical Society.

- 'Juiced-up' battery fueled by sugar could power small portable electronics
03-25-2007 · EurekAlert!
Juicing up your cell phone or iPod may take on a whole new meaning in the future. Researchers at Saint Louis University in Missouri have developed a fuel cell that runs on virtually any sugar source -- including soft drinks -- and has the potential to operate three to four times longer on a single charge than conventional batteries, they say. The research will be presented in March at the American Chemical Society national meeting in Chicago.

- How parents react to material hardship found to be key to how income affects children
02-07-2007 · EurekAlert!
Research drawing from the "Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999" challenges the accepted finding that family income is directly associated with parental stress. The study found that parents who make more money can better provide more cognitively stimulating materials, and that material hardship can lead to parental depression and conflict. These effects in turn may cause parents to show less affection towards children, who then may become depressed or misbehave.

- Sticky mussels inspire biomedical engineer yet again
10-18-2007 · EurekAlert!
Mussels are well known for sticking to virtually all inorganic and organic surfaces and doing so with amazing tenacity. Northwestern University researchers already have developed a material that mimics the strength of the bonds; now they have produced a versatile coating method that mimics the mussels' ability to attach to a wide variety of objects. A broad variety of materials can be coated and functionalized through the application of a surface layer of polydopamine.

- New study evaluates methods to prevent importation of illicit nuclear materials
10-15-2006 · EurekAlert!
New study evaluates the need for security measures to prevent importation of a smuggled nuclear device. On Friday, the president signed the SAFE Port Act, which is a good step towards better port security. However, there are two significant limitations to the act. First, it only requires radiation detection, but two-dimensional scans are necessary to detect a weapon if shielding with dense material is used. Also, the act does not require inspections at overseas ports, which are needed to prevent terrorists from detonating a device at a U.S. port because any attempts at detection occur.
