Summary: Supercapacitors are attracting attention in energy storage fields due to their safety, cost-effectiveness, and environmental friendliness. Pore carbon materials derived from renewable biomass materials are important and cost-effective electrode materials for supercapacitors. However, the low ionic conductivity of biomass materials limits their electrochemical performance. This study introduces an immiscible liquid-mediated method to improve the ionic conductivity of silk-derived nitrogen-doped porous carbon electrodes. The addition of organic liquid promotes ion transport in the electrode pores, resulting in a specific capacitance of 565.3 F g-1 at a current density.

Summary: This paper proposes a novel and effective two-step ethanolysis-esterification strategy for the controllable and simultaneous preparation of 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (OPL), 1,3-dioleoyl-2-palmitoyl-glycerol (OPO), and 1,3-dilinoleoyl-2-palmitoyl-glycerol (LPL) with adjustable proportions. Enzymatic ethanolysis of fractionated palm stearin yields 2-monopalmitoylglycerol (79.4 +/- 0.6 %) with over 91.0 % purity. Using immobilized Candida sp. lipase (CSL) on octyl-functionalized ordered mesoporous silica (OMS-C8), 2-monopalmitoylglycerol is re-esterified with oleic acid and linoleic acid to produce OPL, OPO, and LPL simultaneously.

Summary: To achieve carbon neutrality and carbon peaking goals, sustainable biomanufacturing of high-value chemicals such as 3-hydroxypropionic acid (3-HP) through metabolic engineering of Escherichia coli has been explored. Efforts were made to optimize the biosynthetic pathway, enhance glycerol uptake, and improve the production of 3-HP through genetic engineering and process optimization. The use of corn steep liquor as a cheap fermentation medium further enhanced the production of 3-HP. Co-fermentation of crude glycerol with glucose and acetic acid resulted in high yields and productivity of 3-HP.

Summary: Designing hybrid metal sulfide-based anode materials is an effective method to enhance the performance of sodium-ion batteries (SIBs). However, the capacity of sulfide-based anodes decreases significantly due to volume expansion during charge/discharge processes. In this study, concaved NiS2@CoS2 nano-cubes (NCSC) were successfully prepared through chemical etching of Ni-Co coordination polymers (NiCoCP) precursor. The obtained NCSC anode materials exhibited a high specific sodium storage capacity of 848 mAh g-1 at 0.1 A g-1 and a stable cyclability of 572 mAh g-1 at 5 A g-1 after 830 cycles. This unique etching strategy provides a novel approach for the design and fabrication of high-performance anode materials for SIBs.
