Faculty Hiring Initiative

 NCMN has been planning for faculty development (~ 2 years)  Talk on “Materials and Nanoscience” given to Board of

Regents (2017)

 NNF External Advisory Board Review (2017) supported our

hiring plan

 Many discussions with vice chancellors, deans,

department chairs and faculty Administration approved a set of 4 cluster hires in “Quantum Materials and Technologies”

[Physics, Materials, Chemistry, Electrical Eng.]

 Please let us know of excellent candidates!

 Sinitskii et al. have shown how to produce graphene nano-ribbons

(GNR) by adding benzene rings, reducing its band gap and enhancing its electrical conductivity.

New Graphene Nano-ribbons Lead to Sensors with Unprecedented Sensitivity

GNR-based gas sensor Effect of lateral extension on band gaps  This approach may be extended to sensing other molecules and photovoltaics.

New materials, especially earth-abundant ones, are needed for modern power-generation systems and vehicles.

Combined experimental-computational research is leading to advanced metastable materials with potential for high-temperature use:

Schemes for Funding New Equipment

 Establish Revolving (Savings) Account

  • Difficult to achieve, but carry-over funds

from operations help in equipment purchases.

 Matching Scheme

  • In requesting contributions from

departments, colleges and vice chancellors, providing the largest amount from NCMN/NNF funds helps significantly in obtaining other contributions.
