st snuff is demonstrably less carcinogenic in humans, and less toxic in other ways, because it lacks the combustion products. However, moist snuff products still contain significant levels of carcinogens, and users should stop, perhaps via use of nicotine replacement therapy, rather than switch from one risky product to another, the paper advises.

ARTICLE #4 FOR IMMEDIATE RELEASE

Toward improved non-stick surfaces at the flip of a switch
Langmuir

Researchers in New Jersey report development of a new type of non-stick material whose ability to shed liquids like water from a ducks back can be turned on or off simply by flipping an electrical switch. The material, called nanonails, offers a wide-range of potential applications including contamination-resistant and self-cleaning surfaces, reduced-drag ships, and advanced electrical batteries, they say. Their study is scheduled for the Jan. 1 issue of ACS Langmuir, a bi-weekly publication.

For years, researchers sought to develop surfaces that repel virtually any liquid. Theyve created non-stick surfaces that repel water and certain other liquids, but have had little success with repelling common organic liquids such as oils, solvents and detergents. Tom N. Krupenk
