FDSC 300 Lecture Notes - Lecture 17: Foodborne Illness, Nanomaterials, Elastic Modulus
Document Summary
Nanotechnology: manipulation of matter at the nanoscale to generate size- dependent functionalities different from atom/molecules/bulk materials. Nanomaterial: material with at least one of its dimension is between 1-100 nm. They are expected to produce fibers 100 times stronger than steel at only 1/6th the weight almost certainly the strongest fibers that will ever be made out of anything. In specific cases and where warranted by concerns for the environment, health, safety or competitiveness the number size distribution threshold of. 50 % may be replaced by a threshold between 1 and 50 %. Health canada"s definition: considers any manufactured substance or product and any component material, ingredient, device, or structure to be nanomaterial if: In structures made of nanomaterials the atoms in grain ~ atoms in grain boundaries. Nanotechnology for enhancing nutrient uptake: absorption of nutrients and compounds in the intestine. Cost effective methods for increasing bioavailability of micro-nutrients.
