Unifrax introduces new nano-structured alumina catalyst support technology for a greener catalytic conversion option: Eco-lytic

Green Car Congress

Housed within a vehicle’s catalytic converter, the Eco-lytic catalyst support fiber is designed to replace the existing catalytic converter or add to existing systems in order to enhance emission reduction, consume fewer precious metals and raw materials, and drive lower energy usage through vehicle weight reduction.

3-D nanocone solar cell boosts PV conversion efficiency by nearly 80%

Green Car Congress

We designed the three-dimensional structure to provide an intrinsic electric field distribution that promotes efficient charge transport and high efficiency in converting energy from sunlight into electricity. With this approach at the laboratory scale, Xu and colleagues were able to obtain a light-to-power conversion efficiency of 3.2%

Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Liquid electrolytes are pumped from storage tanks to flow-through electrodes where chemical energy is converted to electrical energy (discharge) or vice versa (charge). Rose, Chad L. The next step for the Sandia team is to find similar materials for flow battery anodes. Pratt III, Alyssa J. Staiger, David Ingersoll and Travis M.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Smaller Ioxus cells offer a power density of 22-28 kW/kg, and larger cells offer densities of 12-15 kW/kg, said Chad Hall, COO of Ioxus. Another application could provide “instant heat” to heat up the catalytic converters in vehicles. Energy densities for the cells are typically around 2-4 Wh/kg.

Can We Identify a Person From Their Voice?

Cars That Think

We hear who you are The methods of automated speech recognition, which converts speech into text, can be adapted to perform the more sophisticated task of speaker recognition, which some practitioners refer to as voiceprinting. Indeed, forensic scientists hope one day to glean as much information from a voice recording as from DNA.
