A novel approach towards PGM-free PEM fuel cell cathodes

Anson C., Gerken J., Preger Y., Biswas S., Root T., Stahl S., University of Wisconsin-Madison, US

One of the major obstacles preventing widespread implementation of PEM fuel cells is the current requirement for prohibitive loadings of Pt at the cathode to achieve high activity for the oxygen reduction reaction. The Pt [...]

Print Transferrable Large-Area Broadband Membrane Reflectors by Laser Interference Lithography

Seo J.-H., Park J., Zhao D., Yang H., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US

Large-area broadband reflectors based on photonic crystals can enable a number of optoelectronic and photonics devices. To create nano patterns, nanoimprinting, electron-beam lithography and focused ion beam patterning techniques are commonly used. However, these methods [...]

Highly sensitive organic-inorganic heterojunction flexible photodetectors

Seo J.-H., Oh T.Y., Park J., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US

Heterostructures formed between inorganic and organic materials could lead to many unique device applications due to their unique physical properties, such as mechanical flexibility, large area, low temperature processability and high performance. Since most n-type [...]

Flexible Graphene Transistors via Printing Transfer

Chang T.-C., Suh H.-S., Mikael S., Seo J.-H., Nealey P.F., Ma Z., University of Wisconsin-Madison, US

Graphene is an atomic layer material with the characteristics of high mobility, high mechanical strength, transparency and low injection energy barrier with different work function metals. Good transparent electrodes and flexible graphene-based large scale touch [...]

Synthesis and Characterization of Novel ZnO-Whey Protein Nanocomposite at Low Temperature

Shi L., Zhou J., Gunasekaran S., University of Wisconsin-Madison, US

The incorporation of nanocrystalline ZnO into whey protein to form nanocomposite will possess the unique functionalities and potential applications in material science and food sciences. Herein we synthesized nanocrystalline ZnO particles coated with whey protein [...]

Functionalization of multiwalled carbon nanotubes with _-lactalbumin and _-lactoglobulin

Zhou J., Yang Q., Pan X., Gunasekaran S., University of Wisconsin-Madison, US

The immobilization of proteins on carbon nanotubes is attracting much attention because the resultant hybrid nanomaterials are potentially useful as biomolecular nanosensors [1]. -lactalbumin and -lactoglobulin are the major proteins in whey, the by-products of [...]

“Cultural Bonds” in High Technology: Collaborations between Chinese Researchers in Nanotechnology

Leung R., Li J., University of Wisconsin-Madison, US

Socio-cultural issues have attracted increasing attention from policy makers in high technology. For example, a certain “culture” of high-tech fear, exemplified by Michael Crichton’s best-selling novel Prey, seems to have emerged in U.S. In this [...]
