The authors' main claim We report here that a two times amplification in absorption efficiency can be achieved by water molecules confined in carbon nanotubes with small radius, compared with situations in normal bulk water, under irradiations of short mid-infrared pulses.

The abstract, sentence by sentence
The energy absorption on nanometer scale is vital for many bio and chemical systems. We report here that a two times amplification in absorption efficiency can be achieved by water molecules confined in carbon nanotubes with small radius, compared with situations in normal bulk water, under irradiations of short mid-infrared pulses. The effect of confinement due to a (6,6) carbon nanotube is found to be very robust, equivalent to that of a 5 $V/nm$ static electric field. These findings are instructive not only for designing high-efficiency nano devices but also for understanding behaviours in biological channels.

Original abstract
The energy absorption on nanometer scale is vital for many bio and chemical systems. We report here that a two times amplification in absorption efficiency can be achieved by water molecules confined in carbon nanotubes with small radius, compared with situations in normal bulk water, under irradiations of short mid-infrared pulses. The effect of confinement due to a (6,6) carbon nanotube is found to be very robust, equivalent to that of a 5 $V/nm$ static electric field. These findings are instructive not only for designing high-efficiency nano devices but also for understanding behaviours in biological channels.
