Self-healing Composite Membranes for Fuel Cell Applications

Wang L., Advani S.G., Prasd A.K., University of Delaware, US

Defects in the form of pinholes and cracks can occur in the membrane due to a combination of chemical and mechanical degradation mechanisms during operation of the polymer electrolyte membrane fuel cell. Such defects are [...]

Dose- and Time-dependent Effects of Sub-chronic Functionalized MWCNT Exposure on Human Mesothelial Cell Neoplastic Transformation Potential

Stueckle T.A., Davidson D.C., Derk R., Gracheck P., Wu N., Rojanasakul Y., Wang L., National Institute for Occupational Safety and Health, US

Multi-walled carbon nanotubes (MWCNTs) are characterized by asbestos-like fiber morphology and surface chemistries. Physicochemical properties of MWCNTs that influence pleural mesothelioma potential are unknown, but critically needed to enhance safe-by-design nanotechnology. We hypothesized that surface [...]

Single-walled carbon nanotubes induce fibrogenic response by promoting fibroblast-to-myofibroblast transition: An in vitro molecular toxicity pathway based risk assessment

He X., Wang L., Rojanasakul Y., West Virginia University, US

Several reports have shown that single-walled carbon nano tubes (SWCNT) caused lung fibrosis in rodents. The molecular mechanisms that govern SWCNT lung toxicity remain largely unaddressed. Our results indicate that SWCNTs induced ROS and mitochondrial [...]

Role of Caveolin-1 in Carbon Nanotube-Induced Stem-Like Cells and Tumorigenesis

Luanpitpong S., Wang L., Castranova V., Stueckle T., Rojanasakul Y., West Virginia University, US

Carbon nanotubes (CNT) hold great promise to create new and better products, but their long-term adverse health effects are a major concern. The objective of this study was to develop an in vitro model for [...]

In vitro Model for Identifying Subchronic Carbon Nanotube Exposure and Lung Cancer Gene Markers

Stueckle T., Davidson D., Derk R., Meighan T., Castranova V., Rojanasakul Y., Wang L., National Institute for Occupational Safety and Health, US

Concern for increased risk of carbon nanotube-associated lung disease, including carcinogenesis, has been raised due to asbestos-like characteristics. To date, no particle specific nanomaterial exposure or lung cancer markers have been identified. Here, we use [...]

In Vitro Assessment of Nano-Cerium Oxide (nCeO2) and Nano-Ferric Oxide (nFe2O3) on Fibrogenic and Carcinogenic Potential

Wang L., Davidson D., Stueckle T., Derk R., Chen M., Sotiriou G.A., Demokritou P., Luanpitpong S., Ma J., Mercer R.R., Castranova V., Rojanasakul Y., National Institute for Occupational Safety and Health, US

Goal of the present study is to investigate the specific cellular responses to nCeO2 and nFe2O3 in various lung cell types and develop an in vitro chronic exposure model to predict the potential fibrogenic and [...]

Single-crystalline 3C-SiC thin-film on large Si substrate for photonic applications

Massoubre D., Wang L., Chai J., Walker G., Hold L., Lobino M., Dimitriev S., Iacopi A., Griffith University, AU

We present our recent progress in the hetero-epitaxial growth of single-crystalline cubic silicon carbide (3C-SiC) on large silicon (Si) wafer and its use for photonic applications. Single-crystalline 3C-SiC thin-film on Si opens new opportunities to [...]

Y2O3:Eu3+, Tb3+ sphere particles doped anti-reflection and wavelength conversion bifunctional films: Synthesis and application to solar cells

Ji R., Hu X., Tian M., Han L., Jun F., Wang L., Wang Y., Zhan S., Zhang Q., Zhang Q., Wang L., Wang Y., Northwest University, CN

Solar energy, as a clean and sustainable resource, has great potential to take place of the traditional energy source. While the low photoelectric conversion efficiency limits the application of solar cells to a great extent. [...]

Transfer of asymmetric free-standing TiO2 nanowire films for high efficiency flexible dye-sensitized solar cells

Xue Z., Wang L., Liu B., National University of Singapore, SG

A free-standing TiO2 nanowire thin film was prepared using the doctor-blade method. The film is composed of big and small nanowires on each side. The big nanowires have the functions of weakening adhesion to its [...]
