The aim of this study is to experimentally investigate the oil retention characteristic of microchannel evaporator and reveal its effect on heat transfer performance. Mixture of R32 and PVE VG68 oil was selected as the working fluid, and two single-pass microchannel heat exchangers with...

The intercalation of spacer is a commonly used method for suppressing re-stacking of MXene nanosheets. However, the intrinsically inactive property of spacer injures the capacitance performance of MXene in acid electrolyte. Here, hexamethylenetetramine (HMT) molecules are used as the...
