Removal of low concentration CO2 at ambient temperature using several potassium-based sorbents

Zhao, Chuanwen; Guo, Yafei; Li, Changhai; Lu, Shouxiang - In: Applied Energy 124 (2014) C, pp. 241-247

The requirement for long-duration human operation in a confined space has made removal of low concentration CO2 a critical technology. The incorporation of organic amines into a porous support is thought to be a promising approach, but the low amine utilization ratio and the loss of amine...

INFLUENCE OF A Cr LAYER ON THE GLASS SUBSTRATE ON THE GROWTH OF CARBON NANOTUBES BY CHEMICAL VAPOR DEPOSITION

IKARI, T.; KOGA, H.; KOJIMA, K.; UEMURA, I.; MIYAZAKI, H.; … - In: Surface Review and Letters (SRL) 16 (2009) 05, pp. 761-765

We report the effect of a Cr layer on the glass substrate during the growth of carbon nanotubes (CNTs) by chemical vapor deposition. When Fe was used as a catalyst in the CNT growth, longer CNTs were obtained by increasing the thickness of the Cr layer. However, CNTs were not grown on the...
