Effect of microwave combined with ethanol pretreatment on the quality of potato CO explosion puffing drying.

To enhance the drying quality of potato slices, this investigation employed a microwave heating (MH) combined with ethanol osmotic dehydration (EOD) pretreatment strategy to improve the quality of explosion puffing drying (EPD). This paper systematically investigated the effects of different pretreatment methods (no treatment, HAD, MH, EOD, MH+EOD) on the quality and physicochemical properties of potato slices subjected to CO-EPD. The results showed that after MH and EOD pretreatments, the internal pores of the potato slices exhibited a uniform porous structure.

Renewable symmetric supercapacitors assembled with lignin nanoparticles-based thin film electrolyte and carbon aerogel electrodes.

Lignin as a natural biopolymer is becoming increasingly in demand due to its eco-friendly properties, while lignin-based electrolyte with high conductivity and reliable durability for applications in supercapacitors is still challenging. Herein, a facile method to prepare lignin nanoparticles (LNPs)-based solid electrolyte thin film (LF) was proposed through chemical cross-linking reaction. The fabricated LF exhibited a distinctive spongy porous structure with the ionic conductivity of 3.

Effect of ethanol osmotic dehydration on CO puffing and drying mechanism of potato.

In order to further improve the drying quality of potato slices, this study investigated the effects of EPD (CO), HAD + EPD (CO), EH + EPD (CO), and FD on the quality and physicochemical properties of potato slices. The changes in solid loss (SL), obtained ethanol (OE), water loss (WL), and moisture content under different ethanol concentrations and soaking times were studied. The effects of WL, SL, OE, and moisture on puffing characteristics were also studied.

Hydraulic performance prediction and optimization of an engine cooling water pump using computational fluid dynamic analysis.

In current research, the hydraulic performance prediction and optimization of an engine cooling water pump was conducted by computational fluid dynamic (CFD) analysis. Through CFD simulation, the pump head, shaft power and efficiency for the original pump at volume flow rate 25 L/min and impeller rotating speed 4231 r/min were 3.87 m, 66.
