TL;DR: Anhydrous DMEA, DEEA and DIPEA are found to absorb carbon dioxide under pressure via chemical binding and physical absorption as discussed by the authors, and the amount of chemically bound and physically absorbed CO2 is directly linked to the CO2 pressure over the liquid.
Abstract: Anhydrous DMEA, DEEA and DIPEA are found to absorb carbon dioxide under pressure via chemical binding and physical absorption. The chemical CO2-bound derivatives of these materials are zwitterionic alkylcarbonate salts which are characterized by high-pressure 13C NMR. DMEA, DEEA and DIPEA absorb 20 wt.%, 17 wt.% and 16 wt.% carbon dioxide, respectively, at 300 psig (20.6 ATM). An increasing chemical carbon dioxide uptake capacity trend of DMEA > DEEA > DIPEA is observed while the physical CO2 absorption trend is DIPEA > DEEA > DMEA. DMEA captures up to 45 mole % (20 wt.%) of CO2 at 500 psig via both chemical binding and physical absorption. The amount of chemically bound and physically absorbed CO2 is directly linked to the CO2 pressure over the liquid. The zwitterion DMEA-CO2 regenerates CO2 and DMEA upon depressurization, allowing for an economical pressure swing regeneration rather than thermal regeneration. DMEA absorbs/releases CO2 repeatedly with no decline in capacity.

TL;DR: This study proposed and demonstrated a simple method for characterising the aggregation behaviour and aggregate structure of ENPs in different natural waters and found that under high ionic strength conditions, aggregation is mainly governed by diffusion and the aggregates formed under these conditions showed the lowest stability and fractal dimension, forming linear, chain-like aggregates.

TL;DR: In this paper, the Fenton activity of mesoporous iron oxide was firstly extended to pH of 3.6-10.0 by the carbon quantum dots and Cu modification (CQDs/Cu-MIO), and the optimum reaction condition was evaluated and the degradation process of OFX was further investigated by FT-IR spectrum.

TL;DR: In this article, the adsorption of thiourea on gold has been investigated as a function of potential and concentration, using a radiotracer method, and the behavior of the system is interpreted in terms of a simple molecular model.
