Summary: Solid-state and quasi-solid-state electrolytes have gained attention for their advantages in leakage prevention, safety, and flexibility. Quasi-solid-state electrolytes show higher energy and power densities due to better ionic conductivity. Organic quasi-solid-state electrolytes with a working voltage window greater than 2.5 V require more attention, while aqueous-based solid-state electrolytes offer easier handling, greater ionic conductivity, and capacitance. Recent developments in water-in-salt polymer-electrolytes have exhibited stability up to 2 V, encouraging further research in aqueous-based quasi-solid-state electrolytes. These electrolytes have potential application in flexible and bendable devices, promoting advancements in portable electronics and wearables.

Summary: This study investigated the changes in microstructure and grain orientation of the Cu3Sn solder joint during isothermal aging at 420 degrees C. It was found that the original Cu3Sn solder joint transformed into full Cu(41)Sn(11) solder joint and eventually into full alpha(Cu) solder joint during aging. The formation of micro-voids during the conversion process resulted in lower reliability of the solder joint. The average grain sizes of interfacial phases exhibited an initial increase followed by a decrease during aging. The preferred orientations of the different phases were also examined.

Summary: By introducing hydrophilic groups into zein, the interaction between zein and water can be changed, which expands its application in the food industry. This study constructed hydrophilic, amphiphilic, and hydrophobic systems of zein through modification methods, and explored the structure and properties of the modified zein. Experimental results showed that the zein-potassium oleate system is hydrophobic, enzymatic modification can obtain a hydrophilic system, and cysteine modification can obtain an amphiphilic system. Various analysis methods also confirmed the hydrophilic and hydrophobic systems obtained by different modification methods. UV, IR, and fluorescence spectra of zein after enzymatic hydrolysis and cysteine modification indicated changes in the hydrophilicity and hydrophobicity of the zein microenvironment. This study provides a feasible approach to broaden the application of zein in the food industry.

Summary: This study introduces a new FA pretreatment technique for recovering SCFAs from PS. The results show that FA pretreatment significantly enhances SCFAs production, resulting in a 4.5-fold increase compared to the control group. Mechanism investigations reveal that FA pretreatment accelerates PS solubilization, destroys EPS integrity, and increases easily biodegradable substrates in the fermentation broth. FA also inhibits methane production, leading to further SCFAs accumulation. The conversion of NH4+-N released during fermentation into FA facilitates the transition of wastewater treatment plants operation from linear to circular mode.

Summary: In this study, the structure and digestive property of starch isolated from wheat bran of different particle size were investigated and compared with wheat flour starch. Results showed that cell-scale milling caused significant destruction of crystalline regions and double helix, and increase in starch digestibility. Wheat bran starch had more resistant starch and lower digestibility compared to wheat flour starch, which were highly correlated with its thinner lamellas, more double helix proportion and compact fractal. This study contributes to the application of bran starch and highlights the effect of supramolecular structure on bran starch digestibility.
