Bacillus Biocathode improves Electricity Generation with Microbial Fuel Cells

Han S., Zhou C., Wang R., Missouri University of Science and Technology, US

In a microbial fuel cell (MFC), biocathodes alleviate the need to use noble catalysts to reduce oxygen, which substantially increases the viability and sustainability of a MFC. Three electrochemically active strains of bacteria are isolated [...]

Semi Critical Assisted-Solvent Extraction: A Highly Thermochemical Technology For Hydrocarbon and Organic Associate Minerals Extraction In Bituminous Coal

Chavez-Gil T., Kang H., Coppin State University, US

The extraction of raw material (gas, hydrocarbon) and hazard contaminants (ash, heavy metals, poly-aromatic hydrocarbons, organic associate minerals, OAM) from bituminous and lignitic coal, are challenge processes in regards of adding economical value at coal [...]

Design of Experiment Based Prediction of Passivity Breakdown Potential for 304L Stainless Steel

Azimi Dastgerdi A., Bellè U., Brenna A., Ormellese M., Pedeferri M., Bolzoni F., Politecnico di Milano, IT

Stainless steels usually have a good corrosion resistance because of the protective passive film that forms on the surface, however they are prone to localized corrosion (pitting and crevice) due to the breakdown of passive [...]

Building Investor Confidence in Energy Storage through Comprehensive Testing and Evaluation

Taube B., Johnson R., McQuilling A., Leufkens P., Hamzavy B., Thompson C., Southern Research, US

The integration and implementation of energy storage to the grid, especially to support mission critical infrastructure, requires a deep understanding of energy storage system functions and performance. In order to build investor confidence in the [...]

Secondary Use Energy Storage System Design Considerations

Starke M., Chinthavali M., Taube B., Spiers D., Schultz B., Southern Research, US

Energy storage technologies are expected to revolutionize the electric power grid by reducing energy costs, providing means to integrate renewables, and increasing grid reliability and resiliency. Numerous demonstration projects of energy storage technologies funded by [...]

Composite Electrode for High Performance Ultracapacitors and Batteries

Brambilla N., Rich D., Park K., Ndiritu S., Nanoramic Laboratories, US

The standard electrodes used in today’s energy storage devices contain a passive organic or polymeric binder. This material affects various electrochemical performance characteristics of an electrode and lowers power density, energy density, and reliability of [...]

Fabrication of a Lower Weight, All 3D Printed Graphene Supercapacitor

Yu Z., Dobbs S., Anderson K., Sun P., Zhu B., Nair A., Wu S., California State Polytechnic University, Pomona, US

Graphene is under intensive study for energy storage devices, such as batteries and supercapacitors, due to its energy density and ability to recharge. These properties make graphene well suited for electric powered UAVs with the [...]

Cobalt Doped (Mn,Ti)- Oxides for Supercapacitors

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

In this investigation, a (Mn,Ti)-oxide (Mn:Ti 65:35 wt%) was prepared using surfactant templating assisted sol-gel method. To prepare this nanocomposite, sol-A with Ti precursor and sol-B containing Mn precursor were separately prepared using the required [...]

Systematic Characterization and Evaluation of Grid-connected Flow Battery Systems

Taube B., Johnson R., McQuilling A., Leufkens P., Hamzavy B., Southern Research, US

This paper provides an overview of flow technologies and how the ESRC’s research and test center of excellence supports the evaluation and validation of various grid-scale flow battery technologies, with systematic characterization and evaluation including: [...]

Dielectric properties of SiO2/PMMA nanocomposites for energy storage

Jobin M., hepia / HES-SO University of Applied Sciences of Western Switzerland, CH

We have made a SiO2:PMMA hybrid nanocomposite based on 150nm spherical silica nanoparticles synthetized by sol-gel method. A molecule containing a methacrylate group (TPM), was chemically grafted to the silica surface to improve the electrical [...]
