| 1 | Flow and heat transfer of nanofluid past stretching/shrinking sheet with partial slip boundary conditions显示文摘The boundary layer flow of a nanofluid past a stretching/shrinking sheet with hydrodynamic and thermal slip boundary conditions is studied. Numerical solutions to the governing equations are obtained using a shooting method. The results are found for the skin friction coefficient, the local Nusselt number, and the local Sherwood number as well as the velocity, temperature, and concentration profiles for some values of the velocity slip parameter, thermal slip parameter, stretching/shrinking parameter, thermophoresis parameter, and Brownian motion parameter. The results show that the local Nusselt number, which represents the heat transfer rate, is lower for higher values of thermal slip parameter, thermophoresis parameter, and Brownian motion parameter. | S.MANSUR A.ISHAK I.POP | 2014 | Applied Mathematics and Mechanics(English Edition)2014，35，11： | 2 |
| 2 | PET-modified red mud as catalysts for oxidative desulfurization reactions显示文摘This work describes the synthesis of catalysts based on red mud/polyethylene terephthalate(PET) composites and their subsequent heat treatment under N2 atmosphere.The materials were characterized by scanning electron microscopy(SEM),temperature programmed reduction(TPR),Fourier transform infrared spectroscopy(FT–IR),X-ray diffraction(XRD),thermogravimetric(TG) analysis and N2adsorption/desorption.The catalysts were evaluated in the oxidative desulfurization reaction of dibenzothiophene(DBT) in a biphasic system.The results indicated that the PET impregnation on red mud increased the affinity of the catalyst with the nonpolar phase(fuel),in which the contaminant was dissolved,allowing a higher conversion(up to 80%) and selectivity to the corresponding dibenzothiophene sulfone.The sulfone compound is more polar than DBT and diffused into the polar solvent as indicated by the data obtained via gas chromatography–mass spectrometry(GC–MS). | Nayara T.do Prado Ana P.Heitmann Herman S.Mansur Alexandra A.Mansur Luiz C.A.Oliveira Cinthia S.de Castro | 2017 | Journal of Environmental Sciences2017，29，7： | 2 |
| 3 | Quo vadis? Bioengineered polysaccharide-based hydrogel scaffolds for damaged central nervous system recovery and regeneration显示文摘Impairments in the central nervous system(CNS)are a prevalent cause of life-long disabilities worldwide,representing serious health,social,and economic concerns(Doblado et al.,2021).During the last decades,with the population eldering and the increase in the life span,we have experienced an increase in CNS-related disorders,like stroke and neurodegenerative diseases(Jarrin et al.,2021). | Isadora C.Carvalho Herman S.Mansur | 2022 | Neural Regeneration Research2022，17，7： | 0 |
