Peter and David Refermat say they had good luck finding a variety of plates at each of the colleges in the area. JERREY ROBERTSPeter Refermat of Amherst, with the help of his dad, David Refermat, set out five years ago to find cars bearing license plates from all 50 states.
The layer-by-layer ionic self-assembly of silica nanoparticles (SiO NPs) and poly(allylamine hydrochloride) (PAH) can yield high-quality, tunable, and cost-effective anti-reflection coatings (ARCs). However, these purely ionic films lack the necessary scratch resistance for long-term stability. The addition of thermally-crosslinking polyelectrolytes, PAH and poly(acrylic acid) (PAA), can provide a solution to this challenge.
