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 [...]

Laser Carbon Interactions

Vander Wal R., Abrahamson J., Penn State University, US

This presentation describes laser heating of carbon materials. The carbon industry has been annealing carbon via traditional furnace heating since at least 1800, when Sir Humphry Davy produced an electric arc with carbon electrodes made [...]

Advances in MOCVD Production of Complex Materials from Single Source Precursors: Phase Pure Metal Phosphide Thin Films for Catalysis and Energy Applications

Whitmire K., Rice University, US

Transient Foaming Behavior of CO2-soluble, Viscoelastic Surfactant in Microfluidic Model, Sand Pack and Limestone Core

Ramadhan G., P. Nguyen Q., The University of Texas at Austin, US

Aqueous foam has been demonstrated through laboratory and field experiments as an effective conformance control technique for gas enhanced oil recovery and carbon sequestration. The use of polymer as an additive to an aqueous foam [...]

Coatings for next-generation harsh environment systems.

DiMaio J.R., Shaughnessy M., Berger K., Morgan B., Haldeman A.T., Tetramer Technologies, US

From space to oil and gas wells, polyimide coatings and films are used to protect critical components such as fiber optic cables, enameled wires, and sensors in harsh environments. Polyimide materials provide exceptional thermal durability, [...]

Graphene Functionalized Mesoporous Mn and Ti Oxides for Supercapacitors

Houck J., Amar V., Shende A., Shende R., Shende A., Shende R., South Dakota School of Mines and Technology, US

In this investigation, several mesoporous nanocomposites such as TiO2/MnO2, TiO2/Mn2O3, TiO2/MnO2/Mn2O3 and TiO2/MnO2/Mn2O3/MnTiO3 were synthesized using the pluronic 123 templating assisted sol-gel method. To prepare these nanocomposites, sol-A with Ti precursor and sol-B containing Mn [...]

All-Solid-State Stretchable Supercapacitors using Polypyrrole-CNT Hybrid Partially Embedded in PDMS

Zhang R., Stevens Institute of Technology, US

Flexible electronics have a wide range of applications in wearable and multifunctional electronics [1], including flexible displays, curved smart phones, electronic skins, and implantable medical devices. Consequently technologies for flexible energy storage have to be [...]

Development of Li-rich Layered Cathode Nanomaterials for High Energy Li-ion Batteries

Tan C., Aegis Technology, Inc, US

There is a great interest in developing energy storage systems based on more advanced lithium ion (Li-ion) battery technology, which has wide applications over the range from small portable electronics (cell phone, laptop) to large [...]

Metal Organic Frameworks and Porous Polymer Network-Based Matrices as Nonflammable Battery Electrolytes

Ozdemir R., framergy, Inc, US

Due to their high energy densities, low self-discharge rates and low maintenance requirements, Lithium ion (Li-ion) batteries represent the preferred battery format, especially when compared to other rechargeable cells such as Ni-Cad and NiMH batteries. [...]

A Review of the Center for Fluorinated Functional Materials

Sun H., University of South Dakota, US

Center for Fluorinated Functional Materials was established in July 2017 with a significant effort from the State of South Dakota. The mission of this center is to build a self-sustained discovery-based research center that boosts [...]
