Airflow-aligned helical nanofilament (B4) phase in topographic confinement

Area of Science:

• Materials Science
• Nanotechnology
• Physics

Background:

• Helical nanofilaments (HNFs) exhibit complex phase behaviors.
• The B4 phase of HNFs is structurally simpler than the higher-temperature B7 phase.
• Topographic confinement and airflow can influence material properties.

Purpose of the Study:

• To investigate the orientation and ordering of the helical nanofilament (HNF) B4 phase.
• To understand the effects of topographic confinement and airflow on HNF B4 phase behavior.
• To explore the potential for new discoveries regarding the physical properties of the HNF B4 phase.

Main Methods:
