Public Input

Community input for the BESAC report Quanta to the Continuum: Opportunities for Mesoscale Science is now closed.  We appreciate the response of the community through four Town Halls in Boston (February 2012), San Diego (March 2012), San Francisco (April 2012), and Chicago (May 2012), the ACS webinar (April 2012), and through the more than one hundred contributions to this web site.  We are now organizing the community responses into a draft report for BESAC’s approval and for release to the community in Fall 2012.

The BESAC Subcommittee on Mesoscale Materials and Chemistry seeks your input for its report on mesoscale materials and chemistry, where classical, microscale and nanoscale science meet. Research opportunities that advance the frontier of mesoscale science are requested in two areas: (i) new mesoscale phenomena and functionality and (ii) facilities, instruments and tools needed to synthesize, characterize and describe mesoscale materials, phenomena and functionalities.

The Mesoscale Materials and Chemistry report draws its motivation from three themes developed in earlier BESAC and BES reports:

  • The need for innovation, articulated in the Science for Energy Technology Report
  • The insights and tools we have gained and are still gaining from nano, articulated in the New Science for a Secure and Sustainable Energy Future Report
  • The grand challenges of materials and chemistry, articulated in the Grand Science Challenges Report

Science for Energy Technology ReportNew Science for a Secure and Sustainable Energy Future ReportGrand Science Challenges Report

These reports can be found on the BES website,

To stimulate your intellectual juices, below are some science, computation, characterization and synthesis directions that relate to the mesoscale frontier

Some meso features

  • Multi-functionality (e.g., battery electrode)
  • Compositional, structural and functional heterogeneity
  • Coherence lengths
  • Surfaces and conformation
  • Statistical differences among samples
  • Structure + dynamics: 4D materials science and chemistry
  • Fluid flow in restricted geometries
  • Metastability
  • Many interacting degrees of freedom: electronic, structural, electromagnetic, . . .
  • Fluctuations
  • Quantum meets continuum
  • Bottom up meets top down
  • Proximity effects
  • Self-assembly
  • Bio-inspiration
  • Complex architectures

Some meso facilities, instruments and tools

  • High performance computation of materials and chemistry
  • In situ and time resolved measurements
  • Multi-modal measurements, concurrent or sequential (e.g., structure and excitation)
  • Long and short time scales: attoseconds (e.g., electronic transitions) to decades (e.g., structural degradation)
  • Synthesis of complex functional materials


The basic unit of input for the BESAC Mesoscale Materials and Chemistry study is the Priority Research Direction, expressed as a Quad Chart, (see the template and example Self Assembly of Inorganic Nanoparticles below). The template and example may be downloaded here. In addition to the Priority Research Direction Quad Chart, you may add additional comments (restricted to 1000 characters)  (download input form here). Bullet format as opposed to sentences or paragraphs is quite acceptable. The information you supply will be communicated to the BESAC Subcommittee on Mesoscale Materials and Chemistry.
