Global Challenges/Chemistry Solutions

American Chemical Society

Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their report on the device — 1,000 times thinner than a sheet of paper — appears in the journal Nano Letters.

Episode 9 – New Fuels (Part 2 of 2)
Join Global Challenges as it investigates a suite of new fuels and energy sources that may help to power society in the years ahead. Scientists are developing these new energy sources to supplement the coal and conventional natural gas we now use to produce electricity for heating, cooling, and lighting. New fuels hold special promise as sustainable energy sources that minimize the release of carbon dioxide and combat global warming. Intro theme and music by Kevin MacLeod (incompetech.com), vo1k

Episode 8 – New Fuels (Part 1 of 2)
Amid growing concern about high gasoline prices, global warming, and limited resources of petroleum, scientists and engineers around the world are on a quest for new fuels — alternatives to conventional petroleum, natural gas, and coal. On their radar screens are new sources of familiar old ethanol that do not strain the food supply and futuristic fuels like “green gasoline” and “designer” hydrocarbons.

Episode 7 – Combating Disease
Despite the revolutionary medical advances in the 20th Century, great challenges lie ahead in our fight against disease. Heart disease, cancer, chronic diseases of aging, infection with the AIDS virus, and antibiotic-resistant microbes are just a few of those challenges. Fortunately, chemists and other scientists are determined to launch new revolutions in medicine — revolutions in the prevention, early diagnosis, and treatment of disease.
