This program contrasts energy conversions in electrolytic and galvanic cells and explores electroplating applications of electrolytic cells, including copper electro-refining. It discusses the concept of competition at electrodes and looks at the process of anodizing. The program explains Faraday’s laws of electrolysis and teaches how to perform calculations using Faraday's laws and present practical applications.

Explaining what corrosion is, this program examines corrosion in iron, steel, and other metals; looks at factors affecting rates of corrosion; and shows how to protect against corrosion through surface coatings and electrochemical methods. It also discusses the difference between corrosion and metal smelting.

This program explores the chemistry and construction of major rechargeable formats: lead-acid, nickel-cadmium, nickel-metal hydride, and lithium-ion. It also discusses spiral cell construction.

This program traces the development of primary cells from the Daniell cell to zinc-carbon dry cells, alkaline cells, button cells, and lithium metal cells. It shows essentials of their chemistry and construction and discusses the advantages and limitations of each format. The program also reviews the concepts of power, voltage, and current; differentiates between a cell and a battery; and explains the differences between cells in series and in parallel....

This program presents basic redox chemistry principles, with a specific look at energy conversion in the Daniell cell. It illustrates how a galvanic cell is constructed and tested and teaches how to write half-cell equations. The program also explains the electrochemical series, discussing its uses and the limitations of predictions based on the series.

This program stirs things up by showing how combining chemicals turns substances into mixtures! You’ll have all the answers, or solutions, on how combinations can be dry, wet, chunky, hearty, smooth, creamy, strong, and even invisible. So don’t lose your concentrations when these solutions are being presented. Topics include: Solutions and Solubility, Expressing Concentration, Raoult’s Law and Colligative Properties, and Non-Ideal Behavior.

Outlining the basic chemistry and construction of fuel cells, this program traces their development from the alkaline fuel cells vital to the U.S. Space program. It discusses the alkaline fuel cell, considers fuel cells and transport and the hydrogen economy, and discusses fuel cells and batteries for electric cars. The program also considers carbon footprints, stationary power, CHP, and portable fuel cells.

Poland's long, tumultuous history makes it a fascinating country to visit. Follow a team of detectives in the Sowie Mountains as they try to crack the mystery of a huge underground maze of tunnels built by the Nazis. See bomb disposal experts find and detonate WWII explosives that are still littered throughout the country. Other stories include Poland's rush to complete six new stadiums in time for the Euro 2012 soccer tournament, a company that makes...

At 4:30 p.m. on October 10, 1957 a fire was discovered inside Britain's first nuclear reactor at Windscale. This dramatic reconstruction tells the extraordinary story of how the fire was eventually put out, and unravels the causes behind it. The medical and scientific legacies are still being felt to this day, with the UK Atomic Energy Authority admitting that as many as people may have been fatally affected by the ensuing contamination. Filmed in...

Antoine Lavoisier--who lived at the zenith of the Enlightenment and died at the hands of the French Revolution--was himself a revolutionary. Closely followed by the burgeoning international scientific community, he competed with the best minds of his time to be the first to explain how chemical processes really work. Aided by a large fortune and his accomplished wife, he employed the most ingenious and expensive technology of his time in a series...
