    • Initial results were obtained from experiments performed under the high-humidity conditions (60-80% relative humidity) that are common in the summer in Worcester. We repeated the experiments under controlled-humidity conditions to verify the reproducibility of the results. Similar results were obtained when crystallizations were carried out in 95% ethanol solutions under low-humidity conditions (25% relative humidity).

    • Glass slides with exposed silanol (SiOH) groups were prepared by treating freshly cut slides with an air plasma (in an SPI-III plasma etcher) for 45 s. These slides are similar to SAM-3, SAM-4, and SAM-5 in terms of their hydrophilicity and hydrogen bonding. They, however, lack the long-range two-dimensional order and periodicity that are characteristic of the SAMs.
