Shape Memory Alloys (02:18)


In solids, atoms, ions, or molecules are organized in definite arrangements. A metal wire returns to its original state when heat is applied. Atoms spontaneously adopt a more open configuration at a higher temperature.

Atomic Arrangements (03:59)

Mineral shapes and colors are the result of highly-ordered chemical compositions. Learn about ionic, metal, covalent, and Van der Waals bonds and hear properties and examples of each bond type.

Carbon Nanotube Sensors (04:29)

Up to 50% of produce spoils before consumption. Researchers are developing a sensor chip using single-walled carbon nanotubes to detect ethylene, emitted by ripening fruit. The gas restricts electron flow and is displayed on a computer graph.

Early Plastics (01:22)

Celluloid substituted natural comb materials in the early 1900s. Polymer chain geometry provides desired properties.

Making Nylon (02:49)

A polymer is a long chain molecule made of monomers. Six carbon chains with amine groups react with acid chlorides to create a thin sheet pulled from solution as a thread.

Pharmaceutical Polymer Research (03:24)

Polymers are paving the way for new drug delivery systems. Researchers are developing a biodegradable polymer like polylactic acid to encapsulate insulin, resist digestive acids, and release to the bloodstream. Learn about the time-release process.

High Temperature Alloys (03:56)

Metal alloys are used in building spacecraft and advanced telescopes. The Solar Probe Plus Spacecraft must withstand extreme temperatures near the sun; SWEAP instruments measure solar wind plasma. Researchers test materials in a vacuum chamber with IMAX projectors.

Solar Probe Plus Mission Materials (03:38)

Researchers use high temperature alloys like TZM to develop heat resistant materials. Adding titanium and zirconium to pure molybdenum reduces creep risk at high temperatures; tungsten is less likely to react in the space environment.

The chemistry of solid-state materials characterizes most of the interactions we have with matter on a daily basis. Chemists take advantage of the complexity of solids to engineer new materials, including nanoparticles, polymers, and advanced metal alloys. These new materials have many potential applications in sensors, advanced drug delivery systems, and space exploration.
