Dehumidification is one of the key challenges facing the air conditioning (AC) industry in the treatment of moist air. Over many decades, the dual role of heat exchangers of AC chillers for the sensible and latent cooling of space has hindered the therma
First, the moisture and the CO2 on the sample were removed by passing N2 gas at 100 °C for 1 h at a flowrate of 30 mL/min. Second, after measuring the sample weight, the temperature was decreased from 100 °C to 75 °C (that is, to adsorption temperature) under N2 flow. Then ...
g The relation between the electron transfer to the ion transfer ratio and the DI water contact angle (WCA) of the materials. h The schematic of WCA effects on the ion transfer and electron transfer in liquid–solid CE. γL, γS, and γL−S denote the liquid–gas interfacial tension,...
