Summary: The solid fluidization exploitation method is a new approach for extracting marine methane hydrate, with thermodynamic stability and methane leakage being key factors. The study found that the process can be divided into pressure control, concentration control, and equilibrium control stages, and that the filling rate of the methane hydrate structure affects stability and decomposition. The study also showed that the fluidization rate affects decomposition and methane leakage, with higher temperatures leading to increased methane leakage.

Summary: Natural gas hydrate is a promising alternative energy source and has attracted much attention due to its controllable exploitation using chemical injections. This study investigates the effect of different concentrations of methanol on methane hydrate decomposition at a molecular level. By combining the parameters of angular order parameter (AOP), radial distribution function (RDF), and mean square displacement (MSD), the role of methanol in the decomposition mechanism of methane hydrates is revealed. The results demonstrate that a 20% methanol solution is optimal for efficient hydrate decomposition, as it promotes the deconstruction of hydrogen bond networks and inhibits the mass transfer effect of methane diffusion. This research provides important insights into the influence of methanol concentrations on methane hydrate decomposition at a molecular scale and offers guidelines for efficient exploitation of natural gas hydrate reservoirs.

Summary: Nanosized ZSM-5 zeolites with high acidity (Si/Al < 15) are advantageous catalysts for obtaining aromatics in C1 chemistry. However, synthesizing these nanosized zeolites in a cost-effective and scalable manner is challenging. In this study, nanosized ZSM-5 (20-50 nm) with high acidity (Si/Al = 11) was successfully synthesized using p-phenylenedimethylene-bis(tripropylammonium) dichloride as the sole organic structure-directing agent (OSDA). The nanosized ZSM-5 demonstrated enhanced aromatics formation compared to bulk ZSM-5 due to its high acidity and shortened diffusion paths in methanol dehydration and non-oxidative dehydroaromatization of methane reactions.

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.
