Cytotoxicity of Nanoparticles Tập 4 Số 1 - Trang 26-49 - 2008
Nastassja A. Lewinski, Vicki L. Colvin, Rebekah Drezek
AbstractHuman exposure to nanoparticles is inevitable as nanoparticles become
more widely used and, as a result, nanotoxicology research is now gaining
attention. However, while the number of nanoparticle types and applications
continues to increase, studies to characterize their effects after exposure and
to address their potential toxicity are few in comparison. In the medical field
in particula... hiện toàn bộ
Graphene Oxide, Highly Reduced Graphene Oxide, and Graphene: Versatile Building Blocks for Carbon‐Based Materials Tập 6 Số 6 - Trang 711-723 - 2010
Owen C. Compton, SonBinh T. Nguyen
AbstractIsolated graphene, a nanometer‐thick two‐dimensional analog of
fullerenes and carbon nanotubes, has recently sparked great excitement in the
scientific community given its excellent mechanical and electronic properties.
Particularly attractive is the availability of bulk quantities of graphene as
both colloidal dispersions and powders, which enables the facile fabrication of
many carbon‐ba... hiện toàn bộ
Graphene‐Based Materials: Synthesis, Characterization, Properties, and Applications Tập 7 Số 14 - Trang 1876-1902 - 2011
Xiao Huang, Zongyou Yin, Shixin Wu, Xiaoying Qi, Qiyuan He, Qichun Zhang, Qingyu Yan, Freddy Boey, Hua Zhang
AbstractGraphene, a two‐dimensional, single‐layer sheet of sp2 hybridized carbon
atoms, has attracted tremendous attention and research interest, owing to its
exceptional physical properties, such as high electronic conductivity, good
thermal stability, and excellent mechanical strength. Other forms of
graphene‐related materials, including graphene oxide, reduced graphene oxide,
and exfoliated gra... hiện toàn bộ
Optical Properties of ZnO Nanostructures Tập 2 Số 8-9 - Trang 944-961 - 2006
Aleksandra B. Djurišić, Yu Hang Leung
AbstractWe present a review of current research on the optical properties of ZnO
nanostructures. We provide a brief introduction to different fabrication methods
for various ZnO nanostructures and some general guidelines on how fabrication
parameters (temperature, vapor‐phase versus solution‐phase deposition, etc.)
affect their properties. A detailed discussion of photoluminescence, both in the
UV... hiện toàn bộ
Carbon Nanomaterials for Advanced Energy Conversion and Storage Tập 8 Số 8 - Trang 1130-1166 - 2012
Liming Dai, Dong Wook Chang, Jong‐Beom Baek, Wen Lu
AbstractIt is estimated that the world will need to double its energy supply by
2050. Nanotechnology has opened up new frontiers in materials science and
engineering to meet this challenge by creating new materials, particularly
carbon nanomaterials, for efficient energy conversion and storage. Comparing to
conventional energy materials, carbon nanomaterials possess unique
size‐/surface‐dependent ... hiện toàn bộ
Perovskite Solar Cells: From Materials to Devices Tập 11 Số 1 - Trang 10-25 - 2015
Hyun Suk Jung, Nam‐Gyu Park
Perovskite solar cells based on organometal halide light absorbers have been
considered a promising photovoltaic technology due to their superb power
conversion efficiency (PCE) along with very low material costs. Since the first
report on a long‐term durable solid‐state perovskite solar cell with a PCE of
9.7% in 2012, a PCE as high as 19.3% was demonstrated in 2014, and a certified
PCE of 17.9% ... hiện toàn bộ
An Overview of the Applications of Graphene‐Based Materials in Supercapacitors Tập 8 Số 12 - Trang 1805-1834 - 2012
Yi Huang, Jiajie Liang, Yongsheng Chen
AbstractDue to their unique 2D structure and outstanding intrinsic physical
properties, such as extraordinarily high electrical conductivity and large
surface area, graphene‐based materials exhibit great potential for application
in supercapacitors. In this review, the progress made so far for their
applications in supercapacitors is reviewed, including electrochemical
double‐layer capacitors, pse... hiện toàn bộ
Fluorographene: A Two‐Dimensional Counterpart of Teflon Tập 6 Số 24 - Trang 2877-2884 - 2010
Rahul R. Nair, Wencai Ren, R. Jalil, Ibtsam Riaz, Vasyl G. Kravets, L. Britnell, Peter Blake, Fredrik Schedin, Alexander S. Mayorov, Shengjun Yuan, M. I. Katsnelson, Hui‐Ming Cheng, Włodek Strupiński, Lyubov G. Bulusheva, А. В. Окотруб, I. V. Grigorieva, A. N. Grigorenko, Kostya S. Novoselov, A. K. Geǐm
AbstractA stoichiometric derivative of graphene with a fluorine atom attached to
each carbon is reported. Raman, optical, structural, micromechanical, and
transport studies show that the material is qualitatively different from the
known graphene‐based nonstoichiometric derivatives. Fluorographene is a
high‐quality insulator (resistivity >1012 Ω) with an optical gap of 3 eV. It
inherits the mechan... hiện toàn bộ
