SCIENCE OBJECTIVES FOR EVERYONE

Production of Two Dimensional NanoTemplate in Microgravity (2D-NanoTemplate) fabricates large and highly oriented nano-scale two-dimensional arranged peptide arrays by suppressing convection and sedimentation.

SCIENCE RESULTS FOR EVERYONE

Honey, I shrunk the peptides! This investigation fabricated nanoscale, two-dimensional peptide arrays by suppressing convection and sedimentation. Peptide particles on the space station were subjected to concentrated sodium hydroxide (NaOH) solution and allowed to arrange for a week in microgravity. The peptides that formed showed patterns similar to those created on the ground, indicating that their motion is not influenced by microgravity. Suppression of convection in microgravity did result in more sophisticated nanopatterns by reducing adsorption of unexpected aggregates. Semiconductor material made of the space-produced nanotemplates will likely have higher quality and performance, advancing development of high-performance computers and blue LED light applications as well as reducing semiconductor manufacturing costs.

RESEARCH OVERVIEW

Production of Two Dimensional NanoTemplate in Microgravity (2D-NanoTemplate) fabricates large and highly oriented nano-scale two-dimensional arranged peptide arrays by suppressing convection, sedimentation, and buoyancy.
The arrangement generated will be used as the template of electronic materials on Earth.
