TL;DR: In this article, a novel interrupted microchannel with double circular pin-fins in each microchamber (IMCDCP) is designed to combine the advantages of micro-chamber and circular pinfin in heat transfer enhancement.

TL;DR: In this paper, the authors investigated the flow and heat transfer characteristics of distilled water in a minichannel heat sink (MCHS) fitted with twisted tapes under laminar flow, and the results showed that average heat transfer coefficient (have), pressure drop per unit length (ΔPpul) and thermal enhancement factor (η) increase with the decrease in twist ratio or/and the increase in twisted tape length.

TL;DR: In this paper , a carboxylated carbon nanotube/chitosan aerogel (CCNT/CA) with switchable wettability was developed as a smart adsorbent for fast oil absorption and oil recovery.

TL;DR: In this paper, the combined effect of concentration-dependent surface charge and surface charge-dependent boundary slip on the flow and related heat transfer in nanochannels with overlapping electric double layers (EDL) was reported.

TL;DR: In this paper , an active photocatalyst (MA-Cu-Fe/CDC) is produced by a simultaneous growth strategy, where columnar-structured components, improved interface compatibility, and increased oxygen vacancy concentration promoted the utilization efficiency of visible light, charge transfer and separation of photoinduced holes-electrons, thus effectively boosting the photocatalytic activity.
