New ternary deep eutectic solvents (DESs), including imidazole (Im), ethylene glycol (EG), and methyltriphenyl phosphonium bromide (MTPB), were synthesized at different molar ratios to absorb SO 2 in flue gas. Excitingly, the EG−Im−MTPB (1:2:1) DES has achieved the unexpected achievement of its absorption capacity being greatly improved to 0.65 g of SO 2 /g of DES (4.43 mol/mol) at 3000 ppm and 30 °C, which is the best performing DES for capturing SO 2 under the same conditions ever reported. The aftereffects of thermodynamic investigation demonstrate that there is a solid compound communication between EG−Im−MTPB (1:2:1) DES and SO 2 . In particular, the enthalpy change (Δ r H m ), entropy change (Δ r S m ), and Gibbs free energy change (Δ r G m ) were plainly determined as −50.45 kJ/mol, −114.57 J mol −1 K −1 , and −16.20 kJ/mol, separately. The Fourier transform infrared, 1 H nuclear magnetic resonance, and quantum chemistry calculation results confirm that multiple active sites, including the N atom of Im and the Br atom of MTPB, are the main factors by which DES effectively absorbs SO 2 . Further, a UNIQUAC method by Aspen Plus V12 is set up for the SO 2 absorption process with 6000 m 3 /h flue gas, indicating that the EG− Im−MTPB (1:2:1) DES can completely absorb SO 2 in the flue gas when the consumption of DES is 26.8 m 3 /h.

A real‐time elemental image generation method with 90FPS on an ordinary PC is proposed for integral imaging light field display, which does not sacrifice accuracy nor requires high‐performance hardware. The method pre‐calculates all available voxels and stores the invariable mapping between each voxel and its homogeneous pixels in a lookup table.
