Combinatorial and high-throughput (C&HT) approaches accelerate research by addressing multiple experimental parameters in a parallel highly efficient fashion...
Polymer brushes have potential as end-tethered lubricants. Brush layers immersed in a good solvent must be compressed to ~16% of their equilibrium height before...
A laser-based O atom beam source together with state-resolved detection techniques are used to characterize the energy transfer dynamics of ground ( 3PJ) and...
At the National Institute of Standards and Technology (NIST) we have a capability for conducting cluster SIMS experiments on both our ion microscope and TOF...
