Control on self-assembly structures of rod-coil-rod (PANI)-(PEG)-(PANI) triblock copolymer

YANG Zhifang, WU Jingao, YANG Yingkui, ZHOU Xingping, XIE Xiaolin

Frontiers of Chemical Science and Engineering 2008, Volume 2, Issue 1,   Pages 85-88 doi: 10.1007/s11705-008-0003-6

Abstract: The self-assembly behaviors of the rod-coil-rod (PANI)-(PEG)-(PANI) triblock copolymer are investigatedThe effects of solvents, concentration and ultrasonic irradiation on self-assembly are discussed.Especially, the triblock copolymer can form a multi-layer, tri-dimensional fibrous network and a petalinestructure from the mono-layer fibrous network with the increase of its concentration in ethanol.Also, the ultrasonic irradiation has a great effect on the self-assembly of the triblock copolymer.

Self-assembly of metal-cholesterol oxidase hybrid nanostructures and application in bioconversion of

Yu Xin, Qiuyue Gao, Yu Gu, Mengyao Hao, Guangming Fan, Liang Zhang

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 3,   Pages 615-629 doi: 10.1007/s11705-020-1989-7

Abstract: A cholesterol oxidase (COD) was hybridized with Ca , Zn , Al , Fe and Mn . After precipitation with PO at 4 °C for 72 h, the resulting pellets were freeze-dried. In scanning electron microscopy assays, the metal-COD complexes revealed flower-like or granular structures after hybridization. Fourier transform infrared spectroscopy assay revealed the characteristic peaks of both the enzyme and metal materials. X-ray diffraction analysis indicated that COD was encapsulated in CaHPO ·2H O-, Zn (PO ) ·4H O-, AlPO -, FeP - and Mn (PO ) ·3H O-based nanostructures, respectively. Differential scanning calorimetry assay indicated significant increases in thermo-denaturation temperatures from 60.5 °C to 167.02 °C, 167.02 °C, 137.70 °C, 172.85 °C and 160.99 °C, respectively. Using steroid derivatives as substrates, this enzyme could convert cholesterol, pregnenolone, dehydroepiandrosterone, ergosterol, -sitosterol and stigmasterol to related single products. Hybridization in metal-based nanostructures could significantly enhance the initial conversion ratio and reaction stability of the enzyme. In addition, substrate selectivity could be affected by various metal materials. Briefly, using Ca , Zn , Al , Fe and Mn as hybrid raw materials could help to encapsulate COD in related metal-enzyme nanostructures, and could help to promote the stability and tolerant properties of the enzyme, while also enhancing its catalytic characteristics.

Frontiers of Structural and Civil Engineering   Pages 1145-1162 doi: 10.1007/s11709-023-0945-2

Abstract: To realize seismic-resilient reinforced concrete (RC) moment-resisting frame structures, a novel self-centeringRC column with a rubber layer placed at the bottom (SRRC column) is proposed herein.For the column, the longitudinal reinforcement dissipates seismic energy, the rubber layer allows therocking of the column, and the unbonded prestressed tendon enables self-centering capacity.
