Li S, Tang W, Zhang W, Guo X, Zhang Q.
PMID: 26477514
Chemistry. 2015 Dec 01;21(49):17762-8. doi: 10.1002/chem.201502825. Epub 2015 Oct 19.

New cross-linking reagents were synthesized and mixed with polystyrene (PS) in solution to form a blend. Thin-films were spin-coated from the blend and then cross-linked by thermal activation at relatively low temperature (100 °C) to form cross-linked gate dielectrics....

PMID: 12349964
Anal Chem. 2002 Sep 15;74(18):4634-9. doi: 10.1021/ac020206d.

A new type of silica-based stationary phase with dramatically improved acid stability compared to any currently available silica-based stationary phase has been developed. Superior low pH stability is achieved by first self-assembling a densely bonded monolayer of (chloromethyl)-phenylethyltrichlorosilane (CMPES)....
