Hassium is a chemical element with the symbol Hs and the atomic number 108. Hassium is highly radioactive; its most stable known isotopes have half-lives of approximately ten seconds.
Lawrencium is a synthetic chemical element with the symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements.
This organic chemistry tutorial is divided into two parts. Part 1, "Selected Derivatives, Hydrocarbons," focuses on the properties of glycerol and phenol; Part 2, "Synthetic Substances," demonstrates properties of polyethylene and the depolymerization of polyethylene.
Can we stop, or even reverse global warming? Follows the work of a Nobel Prize-winning scientist on the Canadian prairies, an inventor in New York who has designed a unique synthetic tree, and a mega-project in Europe where CO2 instead of being sent skyward, is stored far out of harm's way deep beneath the seabed.
New research reveals that loss of sleep leads to increased anger. Researchers are now studying the link between loss of sleep and aggressive behavior. Other segments include bacteria that consume greenhouse gases, a handy robot glove, and drones mapping marine megafauna. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
The transplanting of bone tissue, known as bone grafting, typically involves allograft, which is bone from a deceased donor, or autograft, which comes from the patient's own body. With support from the National Science Foundation, materials scientist Ramille Shah and materials engineer Adam Jakus are working to develop and improve synthetic materials available for bone grafting. Part of the "Science Nation" series.
Consider the following: humans live twice as long as their ancient ancestors did even though their bodies contain different types of synthetic and sometimes toxic substances. This is an unpleasant part of life in the modern age. Explores the health impact, wide variety, and alarming ubiquity of manufactured chemicals. Shows how communities around the world, including Inuit seal hunters, Asian and African farmers, and residents of an industrial town in the United States address the pervasiveness of molecular compounds found in pesticides, plastics, and other products. The benefits of these chemicals are weighed against their dangers.
Kit Parker is a lieutenant colonel in the Army Reserve and has served multiple tours of duty in Afghanistan. Even when he’s not in uniform, this Harvard University bioengineer makes it his mission to protect the men and women of the U.S. armed forces. Parker and his team are developing next-generation nanofibers at the Harvard Materials Research Science and Engineering Center (MRSEC). The unlikely inspiration for Parker’s team is none other than the cotton candy machine. They use their own version of that technology to spin a wide range of polymers, both natural and synthetic, into new fabrics and materials for military use.

Typically, diesel fuel is made from crude oil, but scientists can make high-grade diesel from coal, natural gas, plants, or even agricultural waste, using a process called Fischer–Tropsch (FT). FT Diesel is the ideal liquid transportation fuel for automobiles, trucks, and jets. It’s much cleaner burning than conventional diesel, and much more energy-efficient than gasoline. But, FT Diesel is expensive to make and generates lots of waste. With support from the National Science Foundation and its Center for Enabling New Technologies through Catalysis (CENTC), chemists around the United States are working together to improve the cost and energy efficiency of alternative fuels. Part of the National Science Foundation Series “Science Nation.”
