Directed Assembly of Fullerene on Modified Au(111) Electrodes

03.07.2018 | Zhen-Feng Cai; Wei-long Dong; Ting Chen; Huijuan Yan; Dong Wang; Wei Xu; Li-jun Wan, Chemical Communication, 2018

Here we show a conceptual approach to realize the scanning probe based induced-assembly of fullerene (C60) molecules on top of a buffer organic adlayer at room temperature in solution environment. The realization of spatially-defined C60 assembly is attributed to modulation of substrate-molecular ...

Redox-enhanced hemilability of the tris(tert-butoxy)siloxy ligand at cerium

03.07.2018 | Jochen Friedrich; Yusen Qiao; Caecilia Maichle-moessmer; Eric J Schelter; Reiner Anwander, Dalton Transactions, 2018

The stabilizing effect of the tris(tert-butoxy)silyoxy ligand on cerium(IV) is revealed by electrochemical and computation methods as well as targeted redox chemistry. Ceric homoleptic complex Ce[OSi(OtBu)3]4 was obtained by the reaction of [Et4N]2[CeCl6] with NaOSi(OtBu)3 at ambient temperature ...

Effects of Nd-modification on the activity and SO2 resistance of MnOx/TiO2 catalyst for low-temperature NH3-SCR

03.07.2018 | Wenkui Zhang; hongfeng Chen; Yang Xia; Ruyi Fang; Hui Huang; Yongping Gan; Chu Liang; Jun Zhang; Xuesong Liu, New Journal of Chemistry, 2018

MnOx/TiO2 (MnTi) and Nd-modified MnOx/TiO2 (MnNdTi) were prepared via a coprecipitation method. The used samples were obtained by exposing the fresh catalysts to 50 ppm SO2 stream at 210 oC for 3 h and 6 h, respectively. Comparative investigations were performed on the fresh and used catalysts to ...

Production of Dynamic Lipid Bilayers Using the Reversible Thiol-Thioester Exchange Reaction

03.07.2018 | Danielle Stephanie Konetski; Sudheendran Mavila; Chen Wang; Brady T. Worrell; Christopher N Bowman, Chemical Communication, 2018

Thiol lysolipids undergo thiol-thioester exchange with two phenyl thioester-functionalized tails to produce phospholipid structures that assemble into liposomes with differences in exchange rates, temperature sensitivity, permeability, and continued exchange behavior. This in situ formation ...
