Cystine oligomers successfully attached to peptide cysteine-rich fibrils

Christian Bortolini,Mingdong Dong

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 1,   Pages 99-102 doi: 10.1007/s11705-016-1554-6

Abstract: Amyloid peptides are renowned to be related to neurodegenerative diseases, however, a fruitful avenue is to employ them as high-performance nanomaterials. These materials benefit from the intrinsic outstanding mechanical robustness of the amyloid backbone made of -strands. In this work, we exploited amyloid-like fibrils as functional material to attach pristine L-cysteine aggregates (cystine oligomers) and gold nanoparticles, without the need of templating compounds. This work will open new avenues on functional materials design and their realisation.

Preparation and characterization of SO42-/TiO2 and S2O82-/TiO2 catalysts

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 1,   Pages 45-49 doi: 10.1007/s11705-007-0009-5

Abstract: Nanosized solid superacids SO/TiO and SO/TiO, as well as MCM-41-supported SO/ZrO, were prepared. Their structures, acidities, and catalytic activities were investigated and compared using XRD, N adsorption-desorption, and in situ FTIR-pyridine adsorption, as well as an evaluation reaction with pseudoionone cyclization. The results showed that SO/TiO and SO/TiO possess not only nanosized particles with diameters <7.0 nm, a BET surface greater than 140 cm/g and relatively regular mesostructures with pores around 4.0 nm, but also a pure anatase phase and strong acidity. Different from the Lewis acid nature of SO/ZrO/MCM-41, SO/TiO and SO/TiO exhibit mainly Br¢nsted acidities. The strongest Br¢nsted acid sites were produced on SO/TiO promoted with HSO, while Lewis acid sites on SO/TiO even stronger than those on SO/ZrO/MCM-41 were generated when persulfate solution was used as sulfating agent. Because of their distinct acid natures, SO/TiO and SO/TiO exhibited catalytic activities for the cyclization of pseudoionone that were much higher than that of SO/ZrO/MCM-41. It can be concluded that the existence of more Br¢nsted acid sites was favorable for proton participation in the cyclization reaction.
