Glycerol-Derived Water-Lean Amines for Post-Combustion CO Capture: The Improvement in Capacity and Viscosity.

Water-lean absorbents are regarded as a new generation of post-combustion CO capture technology that could significantly relieve those drawbacks posed by traditional aqueous alkanolamines. However, the exponential increase in viscosity during CO absorption remains an urgent issue that needs to be resolved before their practical deployment. In this work, novel water-lean amines based on biomass glycerol have been devised as single-component CO absorbents with low viscosity (79~110 cP at 25  , 29~39 cP at 40  ) under high capacity (12~18 wt % at 25  , 10~17 wt % at 40  ).

Ultrafast switching to zero field topological spin textures in ferrimagnetic TbFeCo films.

The capability of femtosecond (fs) laser pulses to manipulate topological spin textures on a very short time scale is sparking considerable interest. This article presents the creation of high density zero field topological spin textures by fs laser excitation in ferrimagnetic TbFeCo amorphous films. The topological spin textures are demonstrated to emerge under fs laser pulse excitation through a unique ultrafast nucleation mechanism, rather than thermal effects.
