ISO/TS 80004-8:2020

Overview

ISO/TS 80004-8:2020 - Nanotechnologies - Vocabulary - Part 8: Nanomanufacturing Processes, developed by the International Organization for Standardization (ISO), establishes standardized terminology related to nanomanufacturing processes in the field of nanotechnologies. This technical specification provides definitions critical for clear communication and consistency across industries engaging in nanomanufacturing. While the document focuses on processes capable of generating materials with nanoscale features (approximately 1 nm to 100 nm), it notes that many processes listed are also applicable at larger scales depending on the specific conditions. The vocabulary presented serves as a foundation for stakeholders in sectors such as electronics, biotechnology, energy, and advanced materials to align on terminology and facilitate effective collaboration.

Key Topics

ISO/TS 80004-8:2020 covers a comprehensive range of terms related to nanomanufacturing, grouped according to process type. Key subject areas include:

• General Nanomanufacturing Concepts

  • Nanomanufacturing vs. Nanofabrication
  • Bottom-up and top-down approaches
  • Directed assembly and self-assembly

• Directed Assembly and Self-Assembly Processes

  • Techniques such as electrostatic and magnetic driven assembly
  • Hierarchical assembly across multiple scales
  • Surface-to-surface transfer of nanoscale structures

• Synthesis Methods

  • Gas phase: Physical and chemical vapor processes
  • Liquid phase: Precipitation, sol-gel processing, and hydrolysis
  • Solid phase: Grinding, pressing, and sintering
  • Use of catalysts, surfactant templating, and deposition methods

• Fabrication Techniques

  • Lithography (including nanopatterning)
  • Deposition (e.g., layer-by-layer, co-deposition)
  • Etching, printing, and coating processes

• Material Types and Structures

  • Nano-objects (nanoparticles, nanofibres, nanotubes)
  • Nanostructured materials and composites
  • Functionalization and surface treatments

The vocabulary also identifies which processes are exclusive or non-exclusive to the nanoscale, providing notes within definitions where applicable.
