Manufactured Nanomaterial

  "id": "MLC-T-ENV-016487",
  "term": "Manufactured Nanomaterial",
  "field": "Environment",
  "definition": "1. \"Nanosized materials are purposefully made. These are in contrast to incidental and naturally occurring nanosized materials. Engineering/manufacturing may be done through certain chemical and / or physical processes to create materials with specific properties. There are both \"\"bottom-up\"\" processes (such as selfassembly) that create nanoscale materials from atoms and molecules, as well as \"\"top-down\"\" processes (such as milling) that create nanoscale materials from their macro-scale counterparts. Nanoscale materials that have macro-scale counterparts frequently display different or enhanced properties compared to the macro-scale form.\"\n\n2. Include a wide range of compounds that are intentionally manufactured in a research or commercial setting. They are designed to exhibit specific properties and maintain uniform structures, so that they can be used in a wide range of advanced applications.",
