Den Unit #14

You Be the Teacher - Nanochemistry

QuestionAnswer
Define nanochemistry Branch of chemistry associated with the synthesis of atoms/molecules on the nano-scale.
Define nanoparticle A particle on the nano-scale.
Define nanotubes Nanomaterials made of small cylinders of carbon and boron nitride.
What is materials characterization? The analyzing of the structure and properties of a material.
Define electron microscopes Super-powered microscopes that are used to view particles on the nano-level.
Define "nano-" A billionth (a nanometer is one billionth of a meter)
Define atoms Subatomic particles, the "building blocks" for nanochemists
What are physical properties? Properties involving physical attributes of materials. (e.g. Copper is soft in its graphite form but is incredibly hard on the nano-level)
What are chemical properties? Properties involving the chemical makeup or interactions of materials. (e.g. on the nano-scale atoms/molecules move easier around each other than they do on a larger scale)
What is a catalyst? A substance that speeds up a chemical reaction.
What is Molecular Beam Epitaxy? A method used in nanochemistry; grows single crystals one layer at a time.
What are "nanowhiskers" Tiny surface fibers that coat fabrics (such as blankets or clothing) that help stop dirt from penetrating into the fabric.
Define microelectronics Electronics working at a micro-scale (e.g. microchips)
What is molecular manufacturing? The making of nanomachines.
What is Moore's Law? The name given to the constant increase in computing power as nanotechnology expands. Observed by Intel co-founder Gordon Moore when he noted that the # of transistors per square inch on integrated circuits had doubled every year since their invention.
What common everyday things use nanochemistry? Medicines, microchips, makeup, deodorant, and sun screen all use nanochemistry.
What are nanotubes used for? Insulating or conducting electricity.
What is nanochemistry about? Finding ways to transform (nano)materials into solutions to solve problems.
What is a special characteristic of nanoparticles? High surface to volume ratio.
How does a high surface to volume ratio effect nanoparticles? Gives them extra chemical reactivity.
