Summary: Gas storage technologies are important for energy security and resilience. The use of clathrate hydrates, specifically Solidified Natural Gas (SNG), for natural gas storage is attractive due to its non-explosive nature and high volume density. Recent research has shown that the additive 1,3-dioxolane (DIOX) can improve the thermodynamic and kinetic performance of hydrate formation.

Summary: A secure storage code converts K source symbols of L-w bits to N coded symbols of L-v bits and stores each coded symbol in a node of a graph. The graph has edges associated either with D source symbols or with no source symbols. We characterize the graphs where the capacity of a secure storage code is equal to 1 when D = 1. This result is extended to D > 1, and we also characterize the graphs where the capacity is equal to 1/D and 2/D.

Summary: Surfactants play a significant role in promoting the nucleation and growth of hydrates. Understanding the promoting mechanism of hydrates by surfactants is crucial for hydrate application technology. Amino acid surfactants are environmentally friendly and easily degradable, and they have been used to investigate their effects on hydrate formation. Specific amino acid surfactants with glutamic acid as the head group and longer aliphatic acyl chains prove to be effective in promoting hydrate formation. Sodium cocoyl glutamate and sodium stearoyl glutamate enhance and stabilize hydrate nucleation. Microscopic imaging techniques reveal that hydrate nucleation first occurs at the surface of HCFC-141b droplets, and the formation of hydrophobic HCFC-141b droplets with the help of amino acid surfactants is the key to improving nucleation and growth.

Summary: Based on molecular dynamics simulation, the co-condensation processes in the Si-Ge system during cooling were investigated, leading to the synthesis of liquid-like SiGe nanoclusters. It was found that the cluster size rapidly increased through the coalescence of transient small clusters, and these transient clusters had slightly Si-rich compositions and liquid-like structures at different temperatures. At high temperatures, the coalescence of nanoclusters resulted in spherical clusters with homogeneous intermixing, while irregularly shaped clusters with attached mixed parts were obtained at low temperatures. The restructuring process caused Ge atoms to move to the cluster surface, resulting in slightly Ge-rich components on the cluster surface. The degree of intermixing was related to cluster size, with small clusters appearing to be more segregated during restructuring.

Summary: In recent decades, low salinity water flooding (LSWF) has gained attention for its effectiveness in oil recovery. However, there is a lack of studies in the literature on the potential of using Ionic Liquids (ILs) as candidates for chemical enhanced oil recovery (CEOR) combined with LSWF. This study evaluates the synergistic effect of ILs with varying chain lengths with low saline ion tuned seawater (ITSW) for enhanced oil recovery from carbonate reservoirs. The analysis shows that ILs demonstrate a better synergistic effect with ITSW, reducing interfacial tension, altering rock wettability, and exhibiting less adsorption density at the reservoir temperature. ILs with the longest chain length ([C12mim] [BF4]) show superior properties and significantly increase oil recovery in low saline ITSW.

Summary: Low salinity water flooding is cost-effective and environmentally friendly, and the addition of nanoparticles and polymers can significantly increase oil recovery. The viscosity of complex chemical slugs can be increased by adding nanoparticles to polymer solutions. Low salinity water requires a lower concentration of polymer to reach the target viscosity compared to high saline formation water. The addition of nanoparticles reduces interfacial tension and contact angle, leading to higher oil recovery in low salinity water. Injection of low salinity water-based complex fluid results in incremental recovery of OOIP compared to low salinity water and conventional formation water flooding.

Summary: This study aims to investigate the synergistic effects of two nonionic surfactants (Tergitol 15-S-12 and PEG 600) on surface properties, including surface tension, interfacial tension (IFT), and wettability alteration, in chemically enhanced oil recovery (EOR). The optimum composition of the surfactant mixture, determined through surface tension measurement, showed a minimum surface tension value of 30.3 mN/m at a concentration of 225 ppm of Tergitol 15-S-12 and 1 wt % of PEG 600. The surfactant mixture exhibited an ultra-low IFT of 0.672 mN/m at optimum salinity. The wettability alteration study revealed a shift in rock wettability from oil-wet to water-wet region through contact angle observations and X-ray diffraction analysis.

Summary: The low salinity water flooding (LSWF) technique is cost-effective and environmentally friendly, but its mechanisms are not yet clear. Recovery in LSWF depends on fluid/fluid and rock/fluid interactions. This study investigated both interactions and found different optimal conditions for improved oil recovery. Rock/fluid interaction showed an incremental recovery of 14%, while fluid/fluid interaction showed an incremental recovery of 7% over simple seawater injection. Results highlight the importance of considering both interactions and wettability alteration in LSWF design.

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.
