Chemical Society meeting Aug. 28 - Sept. 1 features variety of multidisciplinary research

07/11/05

Washington, D.C, sessions include findings on a new way to fight antibiotic-resistant bacteria, a coating that keeps car windows from fogging and the latest in counterterrorism techniques

A close look at chemical plant safety, new kinds of carbohydrate foods that may help you lose weight and a permanent coating that prevents car windows from fogging — these are just a few of the findings chemists will present at the 230th national meeting of the American Chemical Society in Washington, D.C., Aug. 28 - Sept. 1. The world-wide lineup of scientists will feature presentations on research in health, medicine, food, agriculture, energy, materials, nanotechnology, biotechnology, green chemistry and the environment.

The meeting will be held at the Washington Convention Center, 801 Mt. Vernon Sq., and surrounding hotels. More than 12,000 scientists are expected to attend and more than 7,400 presentations are scheduled. The American Chemical Society is the world's largest scientific society.

On Monday, Aug. 29, a Presidential Symposium on "The Future of Chemical Plant Security: Where Will We Be in 2015?" -- hosted by ACS President William F. Carroll, Ph.D., -- will feature a presentation by Charles E. McQueary, Ph.D., Under Secretary for Science & Technology, Department of Homeland Security, on what the U.S. Government is doing to combat chemical threats nationally. The program is one of a series of symposia related to "Enterprise 2015," a society-wide effort led by Carroll to identify potential changes in the chemical enterprise in the next decade.

Also on Monday, a symposium on "Bioactive Polysaccharides in Diet, Disease, and Coronary Heart Disease" will focus on newly created forms of super carbs which, when added to foods like baked goods, yogurt and smoothies, help fill you up, without loading on the calories. Foods with the super carbs are designed to help keep the weight off and reduce the risk of diabetes, heart disease and obesity. Super carbs contain increased helpings of soluble oat fiber, which can lower blood sugar and bad cholesterol. Studies on peanut butter and sugar cookies made with the new super carbs found no change in the taste. The Division of Agricultural & Food Chemistry will host this symposium.

On Tuesday, Aug. 30, and Wednesday, Aug., 31, a symposium on "Cosmetic Nanotechnology: Polymers and Colloids in Personal Care" will explore how these particles are being used, as well as potential regulatory implications of their use in light of growing evidence that some particles might pose health hazards. Today, consumers are looking for added benefits from traditional "beauty" products such as moisturization and sun protection. Researchers will offer solutions to the problem of incorporating nanoparticle sunscreens into water for silicone liquid makeup. The symposium is hosted by the Division of Polymer Chemistry.

Also on Tuesday, a symposium on "Tobacco Carcinogenesis," the first such national or international symposium on the subject in five years, will take a close look at the latest findings on how tobacco carcinogens cause cancer. A key objective is to learn more about how tobacco-related cancers may be prevented. Researchers also will discuss ways to decrease the cancer risk for the 1 billion tobacco users across the globe and examine new products that are advertised as less harmful. Another focus will be on how nicotine addiction develops. The Division of Chemical Toxicology is the host for this session.

Other highlights include:

  • Nanoparticles that could help detect Alzheimer's disease in living patients

  • A series of counterterrorism symposia that examine a variety of sensors that detect explosives, radiation, biological agents and nuclear materials

  • New evidence that chocolate can help fight atherosclerosis

  • Certain kinds of mushrooms that might strengthen bones, lower cholesterol and fight cancer

  • The largest, most comprehensive list of antioxidants in some commonly consumed foods, revealing some surprising sources

  • New ways to attack antibiotic-resistant bacteria by targeting different parts of the invading organisms

  • A permanent nanoparticle coating that could prevent the fogging of car windows

  • A new lotion that repairs DNA damage from the sun could reduce the incidence of skin cancer

  • A new treatment that blocks the development of tumors by changing a cell's metabolism rather than killing the cell directly

  • Advances in fuel cell research, including production and storage of hydrogen for hydrogen-powered fuel cells
