Summary: A one-pot strategy for the conversion of corn stalk to ethyl levulinate and the extraction of valuable lignin catalyzed by ionic liquids (ILs) was proposed in this work. The optimized catalyst of [C3H6SO3Hmim]HSO4 achieved a favorable ethyl levulinate yield of 24.72% from corn stalk at 200 degrees C for 90 min. The lignin extraction was greatly influenced by the cosolution system, with a high lignin yield of 79.94% achieved in a 75% (v/v) ethanol-water system. This study demonstrated the morphological, thermal, and functional group changes during lignin liquefaction, and the 2D-HSQC analysis confirmed the presence of a stable lignin structure that facilitated its valorization. Overall, this work proposes a feasible biorefinery strategy for the effective conversion and utilization of lignocellulosic biomass.

Summary: This study proposes the use of red mud as a catalyst for steam gasification of corn stover to produce high-quality reducing gas. The results show that increasing the reaction temperature promotes the production of CO, CO2, and H2. Fe2O3 promotes gas-phase reactions, while Al2O3 facilitates the production of CH4 and H2. The presence of CaCO3 inhibits certain reactions and reduces the production of H2. Red mud exhibits superior catalytic performance compared to pure Fe2O3.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
