| 1 | A Simple Method of Electrospun Tungsten Trioxide Nanofibers with Enhanced Visible-Light Photocatalytic Activity显示文摘The present study involves the fabrication of tungsten trioxide(WO3) nanofibers by an electrospinning technique using polyvinyl pyrrolidone(PVP)/citric acid/tungstic acid as precursor solution. It was found that the PVP concentration was one of the most crucial processing parameters determining the final properties of WO3 nanofibers. The optimum concentration of PVP was from 75 to 94 g L-1. The average diameter of the nanofibers increases with increasing the PVP concentration, whereas it is decreased after sintering and orthorhombic structure were formed at 500 °C. The photocatalytic properties of the as-synthesized nanofibers were also investigated by degrading methylene blue and twofold efficiency was obtained compared with that of commercial WO3 microparticles. | Frank Agyemang Ofori Faheem A.Sheikh Richard Appiah-Ntiamoah Xinsheng Yang Hern Kim | 2015 | Nano-Micro Letters2015，7，3： | 4 |
| 2 | 硅负载离子液体的合成、表征以及其催化甲酸和三乙基胺作为氢源的环己酮还原胺化反应(英文)显示文摘A silica supported ionic liquid was synthesized and characterized by scanning electron microscopy(SEM), Fourier transform infrared spectroscopy, X-ray diffraction, N2 adsorption-desorption, and thermogravimetric analysis. All these techniques, especially SEM results indicated the presence of well-defined spherical particles having diameters larger than the pristine silica particles, confirming the successful immobilization of the ionic liquid. The prepared silica supported ionic liquid was used in the reductive amination of cyclohexanone under different conditions with different azeotropic mixtures of formic acid and triethyl amine as a hydrogen source. The catalyst showed efficient catalytic performance and excellent yields of N-cyclohexyl amine derivatives in the range of 58% to 84% at 30 °C. After completion of the reaction, the catalyst was easily recovered by simple filtration and reused for another five cycles without any significant impact on product yields. The obtained catalytic performance indicates that the present catalyst is green, very active, and reusable for the reductive amination of cyclohexanone. | Ashif H.Tamboli Avinash A.Chaugule Faheem A.Sheikh Wook-Jin Chung Hern Kim | 2015 | 催化学报2015，36，8： | 4 |
| 3 | Recent Progress in the Biological Basis of Remodeling Tissue Regeneration Using Nanofibers:Role of Mesenchymal Stem Cells and Biological Molecules显示文摘Opening up new and unlimited avenues in the biomedical field,tissue engineering and regenerative medicine,the electrospinning process is considered as a versatile and the most preferred technique for the fabrication of nanofibers.These tailor-designed nanofibers provide a desirable and bio-inspired physiological niche to cells for better attachment and subsequent proliferation.In this review,an attempt is made to explain the importance of various topological and morphological parameters of nanofibrous scaffolds for efficient bio-mimicking.Some novel approaches(e.g.,appropriate functionalization and extracellular matrix derived from decellularization)utilized for better mimicking and exponential growth of regenerating tissues are also discussed.Furthermore,this review highlights the important parameters necessary for the attachment,proliferation and differentiation of the mesenchymal stem cells for tissue regeneration.The importance of growth factors and their role after introducing the electrospinning techniques for efficient delivery and their role in the proliferation of mesenchymal stem cells in the different specific lineage(e.g.,tenogenic,chondrogenic,neurogenic and osteogenic differentiation)are discussed. | Roqia Ashraf Hasham S.Sofi Hern Kim Faheem A.Sheikh | 2019 | Journal of Bionic Engineering2019，16，2： | 0 |
| 4 | Recent progress in MXenes incorporated into electrospun nanofibers for biomedical application: Study focusing from 2017 to 2022显示文摘After discovering a new class of two-dimensional(2D) material, i.e., MXene, a further new scope, came into existence for researchers. Due to their remarkable physical, chemical, and biological properties, MXenes find their role in almost every research discipline. They have been used in biosensors, bioimaging,tissue engineering, drug delivery systems, and other areas. The MXenes can be functionalized with a wide range of atoms/molecules, making them diverse materials. Therefore, the potential of using MXenes in nanofibers can be much more than expected. In this review, we will understand the structure, synthesis,and general properties of MXenes. We will explain using MXenes while encasing them into nanofibers,providing their specific properties. For instance, MXenes-incorporated nanofibers are used in biomedical applications, including soft and hard-tissue engineering and delivery of antimicrobials. Furthermore, MXenes, when incorporated into nanofibers, are used in promoting cellular differentiation, wound healing,and neural tissue restoration, which are briefly discussed in this communication. | Muheeb Rafiq Sami-ullah Rather Taha Umair Wani Anjum Hamid Rather Rumysa Saleem Khan Anees Ellahi Khan Ibtisam Hamid Haseeb A.Khan Abdullah S.Alhomida Faheem A.Sheikh | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
