Recoverable Lightweight Nanocomposites

Huckleby A.B., Li J., Shahrizan Jamal M., Zhang M., Florida State University, US

The demand for lightweight and strong structures continues to rise especially for weight critical applications such as aerospace and automotive. It is also desired that the materials can recover after being deformed. In this work, [...]

The Fabrication and Characterization of Nanocarbon Foam as Novel Wick Material for Thermal Management of Electronics

Li J., Xie J., Zhang M., Florida State University, US

Semiconductor devices have suffered large on-chip temperature gradients due to localized high heat flues resulting from the substantial non-uniformity in power dissipation. To solve the heat problems, the flat heat pipes (HPs) are excellent candidates [...]

Chemiresistive hydrogen (H2) gas sensor based on viral-templated Pd nanowires

Moon C.H., Yan Y., Zhang M., Myung N.V., Haberer E.D., University of California Riverside, US

Palladium (Pd) has been widely used for H2 sensing applications because it readily forms a solid solution with hydrogen, modifying electrical resistance. Because the resistance change is diffusion-limited, Pd nanostructured materials with large surface area [...]

Nanocrystalline gold-based hydrogen sulfide (H2S) sensor from M13 bacteriophage template

Moon C.H., Zhang M., Yan Y., Myung N.V., Haberer E.D., University of California Riverside, US

Bio-templated assembly of inorganic materials is a promising technique for facile bottom-up assembly of complex and unique nanostructures at ambient conditions. Here, viral-templated nanocrystalline gold nanowires were synthesized for use in highly sensitive H2S sensors [...]

Harnessing the resistive-elastic behavior of novel CNT-graphene hybrid foams for practical sensing applications

Wolmarans F., Van H.H., Li S.J., Liu T., Liu T., Zhang M., Florida State University, US

Carbon nanotube (CNT) foam and aerogels hold promise in the area of strain sensors because of their resistive-elastic behavior under compressive strain. To date one of the largest obstacles in the area of CNT foam [...]

The scavenging of reactive oxygen species and the potential for cell protection by fullerenols with different isoelectric points

Li J., Liu X., He R., Chang Y., Zhang M., Liu X., Jin J., Sun B., Zhao Y., Xing G., Chinese Academy of Sciences, CN

Fullerenols were known as the major water-soluble derivatives of fullerene that possess particular signiﬁcance biological effects such as anticancer active and free radical scavengers. We have reported a novel method for purifying nanoparticles of fullerenols, [...]

Fabrication and Characterization of Carbon Nanotube/Graphene Hybrid Foam

Zhang M., Cui Y., Li S., Florida State University, US

CNT foam is a material with a porous structure constructed with nano-porous carbon, carbon nanotubes (CNTs). It is expected that CNT foam derives many of its functions from both its nanostructure and its microstructure and, [...]

Microfluidic Control of Adipose-Derived Stem Cell Growth and Positioning

Wadhawan N., Kalkat H., Ma X., Gajjeraman S., Nandagopal S., Hao N., Deng J., Xiang B., Zhang M., Tian G., Lin F., University of Manitoba, CA

Microfluidic devices provide powerful new tools for quantitative stem cell research owing to its advantages in cellular microenvironmental control and experiment throughput over conventional methods. Particularly, microfluidics is playing a growing role in studying stem [...]

From Electrical to Fuel Powered Artificial Muscles

Kozlov M.E., Oh J., Mirfakhrai T., Zhang M., Fang S., Ferraris J.P., Madden J.D.W., Baughman R.H., University of Texas at Dallas, US

A number of materials ranging from carbon nanotube yarns and sheets to shape memory alloys (SMA) have been explored for the application in the area of artificial muscles (actuators). It was found that if powered [...]

Intracellular Uptake of Folate Receptor Targeted Superparamagnetic Nanoparticles for Enhanced Tumor Detection by MRI

Sun C., Veiseh O., Kohler N., Gunn J., Lee D., Sze R., Hallahan A., Zhang M., University of Washington, US

Tumor specific superparamagnetic nanoparticle conjugates are currently being developed as targeting-contrast agents for magnetic resonance imaging (MRI). The application of such “smart” molecular imaging probes will have a significant clinical impact as a non-invasive method [...]
