A high temperature, lithium orthosilicate based solid absorbent for post combustion CO2 capture

Quinn R., Air Products and Chemicals, Inc., US

Capture of carbon dioxide from combustion processes presents a unique and challenging technical problem arising from low CO2 partial pressures, high flow rates, and the presence of water vapor and reactive contaminants such as SO2. [...]

Effect of Streamlined Design of High-speed Coach on Fuel Economy and Emission

Kim C-H, Ha J.H., Seoul National University of Science & Technology, KR

Aerodynamic design of high-speed coaches have been made to reduce aerodynamic drag for lower fuel consumption and to keep the driving stability of the vehicle on a highway. However, the external body shape of a [...]

Simultaneous removal of nano-sized contaminant particles with multi-modal size distribution using hybrid particle beams

Kim I., Lee J.W., POSTECH, KR

The removal of contaminant particles(CPs) as small as 10nm from wafer surface is essential in successful fabrication of nano-scale devices. The supersonic particle beam technique using nano-sized volatile bullet particles(BPs) was extremely effective in removing [...]

Carbon Capture and Recycling by photocatalysts supported on Silica Nanosprings

Prakash T., Marin-Flores O.G., Cantrell T., Grant Norton M., McIlroy D.N., Corti G., GoNano Technologies, Inc., US

Greenhouse Gas mitigation is seen as a necessity by both the USA and the international community. GoNano Technologies Inc. is currently developing Carbon Capture and Recycling(CCR) technology as an alternative and/or a complement to the [...]

Removal of 10-nm contaminant particles from a wafer surface with supersonic CO2 particle beam

Kim E-J, Kim I-H, Kim E-J, Kim I-H, Lee J.W., POSTECH, KR

Contaminant control is becoming a major issue of nano-scale devices. Cryogenic aerosol beam using micron-sized aerosol particles has long been successfully used to remove contaminant particles (CPs) down to 50nm, and supersonic particle beam using [...]

Algerian Renewable Energy Projects for Clean Environment

Himri S., Himri Y., Malik A.S., Himri S., Himri Y., Boudghene Stambouli A., SONELGAZ, DZ

Renewable energy sources RES (solar, wind resources, biomass, geothermal, etc.) that use indigenous resources and that supply16% of the total world energy demand, have the potential to provide energy services with zero or almost zero [...]

Energy-efficient electrochemical CO2 capture from the atmosphere

Eisaman M.D., Schwartz D.E., Amic S., Larner D., Zesch J., Littau K., Palo Alto Research Center, US

In this contribution, we report on the experimental demonstration of a continuously operating modified fuel cell capable of capturing CO2 at atmospheric concentrations with record efficiency. The atmosphere provides O2 and CO2 at the cathode, [...]
