    Modification of the interface between TiO2 and electrolyte toward higher efficiency dye sensitized solar cells by Wang, Xiu

    Published 2014
    “…This thesis is featured with two main approaches for improving the performance of DSSCs: a direct modification on TiO2 surface through surface treatment and molecular passivation and an indirect modification to alter the TiO2 surface charge through adding nanoparticles such as hydrotalcite and silica into the electrolyte. …”

    Extraction, purification and characterization of amylase enzyme from white pitaya (Hylocereus undatus (Haworth) britton & rose) peel using aqueous two- phase system by Shad, Zahra

    Published 2015
    “…It was found that optimum condition for amylase extraction was with sodium phosphate buffer pH 6 and buffer to sample ratio of (1:4) for 2 min which yielded the enzyme with specific activity of 5.89 U/mg. The purification of amylase was studied with ATPS method polyethylene glycol/sodium citrate. …”

    Tricyclononenes and tricyclononadienes as efficient monomers for controlled ROMP: understanding structure–propagation rate relationships and enabling facile post-polymerization modification by Kilgallon, Landon J., McFadden, Timothy P., Sigman, Matthew S., Johnson, Jeremiah A.

    Published 2024
    “…Furthermore, the TCND diester—which contains an electron-deficient cyclobutene that is resistant to ROMP—and its polymer p(TCND) are shown to be highly reactive toward DBU-catalyzed conjugate addition reactions with thiols, providing a protecting- and activating-group free strategy for post-polymerization modification.…”

    Novel single-step hydrophobic modification of polymeric hollow fiber membranes containing imide groups : its potential for membrane contactor application by Zhang, Yuan, Wang, Rong, Zhang, Lizhi, Fane, Anthony Gordon

    Published 2013
    “…Poly(amide–imide) (PAI) hollow fiber membrane with controlled pore structure as porous substrate was fabricated by dry-jet wet spinning process, followed by a wet-chemical hydrophobic modification using octadecylamine. The modification mechanism was confirmed by ATR-FTIR, and the effect of different modification times on the modified membrane properties was investigated. …”
