Neural Regeneration Research 2018年第1期13卷 35-42页

作者： Kyriakos Dalamagkas Magdalini Tsintou Alexander M.Seifalian Department of Tissue Engineering Harvard Medical School nanotechnology & Regenerative Medicine centre Division of Surgery and Interventional Science University College London nanotechnology & Regenerative Medicine Commercialisation centre (Ltd). The London Bio Science Innovation Centre

Spinal cord injury （SCI） is a highly debilitating neurological disease, which still lacks effective treatment strategies, causing significant financial burden and distress to the affected families. Nevertheless, nanotechnology and regenerative medicine strategies holding promise for the development of novel therapies that would reach from bench to bedside to serve the SCI patients. There has already been significant progress in the field of cell-based therapies, with the clinical application for SCI, currently in phase II of the clinical trial. Stem cells （e.g., induced pluripotent stem cells, fetal stem cells, human embryonic stem cells, and olfactory ensheathing cells） are certainly not to be considered the panacea for neural repair but, especially when combined with rehabilitation or other combinatorial approaches using the help of nanotechnology, they seem to be the source of some of the most promising and clinical translatable cell-based therapies that could help solving impactful problems on neural repair.

Applied bias photon-to-current conversion efficiency of ZnO enhanced by hybridization with reduced graphene oxide

引用

Journal of Energy Chemistry 2017年第2期26卷 302-308页

作者： Sharifah Bee Abdul Hamid Swe Jyan Teh Chin Wei Lai Siglinda Perathoner Gabriele Centi nanotechnology and Catalysis Research centre (NANOCAT) University of Malaya Department of Industrial Chemistry University of Messina

The role of reduced graphene oxide（rGO） in the enhancement of photo-conversion efficiency of ZnO films for photoelectrochemical（PEC） water-splitting applications was analyzed. ZnO and rGO-hybridized ZnO（rGO/ZnO） films were prepared via a two-step electrochemical deposition method followed by annealing at 300 °C under argon gas flow. The physical, optical and electrochemical properties of the films were characterized to identify the effect of rGO-hybridization on the applied bias photon-to-current efficiency（ABPE） of ZnO. Scanning electron microscopy and X-ray diffraction indicated the formation of verticallyaligned, wurtzite-phase ZnO nanorods. Diffuse-reflectance UV–visible spectroscopy indicated that rGO-hybridization was able to increase the light absorption range of the rGO/ZnO film. UPS analysis showed that hybridization with rGO increased the band gap of ZnO（3.56 eV） to 3.63 eV for rGO/ZnO sample,which may be attributed to the Burstein–Moss effect. Photoluminescence（PL） spectra disclosed that rGOhybridization suppressed electron-hole recombination due to crystal defects. Linear sweep voltammetry of the prepared thin films showed photocurrent density of 1.0 and 1.8 m A/cm;for ZnO and rGO/ZnO at+0.7 V, which corresponded to an ABPE of 0.55% and 0.95%, respectively. Thus, this report highlighted the multi-faceted role of rGO-hybridization in the enhancement of ZnO photo-conversion efficiency.

A Comparative Investigation of Dye-Sensitized Titanium Dioxide(TiO_2) Nanorods Grown on Indium Tin Oxide(ITO) Substrates by Direct and Seed-Mediated Hydrothermal Methods

We report a comparative investigation of the characteristics of modified TiO2 nanorods grown on conducting indium tin oxide glass （/TO） substrates by two different hydrothermal methods： the direct method by which rutile TiOa nanorods were grown directly on plain ITO substrates and the seed-mediated one using which a thin film of anatase TiO2 seed layer was laid down by spin coating and annealing prior to the growth of TiO2 nanorods on it. Microstructural analysis of the samples using X-ray diffraction confirmed their rutile nature. The average crystallite size estimated using Scherrer＇s formula was found to fall in the range of 11-17 nm in both cases. Field emission scanning electron microscopy revealed the nanorod morphologies of a dandelion arrangement in the case of directly grown ones and a proper vertical orientation in the case of the seed-mediated method. UV-Vis spectroscopy analysis of both the samples exhibited redshifts with intense absorption of visible radiation, and the seed-mediated one was found to possess an increased bandgap. The transport nature of the samples was characterized by significant increase in both dark and photocurrents. The results show that the dark and photocurrent values of the directly grown TiO2 nanorods were greater than those of the seed-mediated ones by - seven and five folds, respectively, and therefore, it could serve as efficient photoelectrodes in dye-sensitized solar cells.

About a decade ago, the unveiling of generalized Snell’s laws heralded a significant advancement in nanophotonics, leading to the emergence of metasurfaces1-6. This revolutionary milestone has set the stage for the development of advanced optical devices, particularly metalens7-11. Researchers are already well-versed in the fundamental principles and functions of meta-lenses, which exemplify the concept of phase discontinuities with clarity.
