Summary: Designing interfaces with thermodynamic and kinetic specificity is crucial for hydrogen storage. The addition of a thin layer of MgCl2 on a porous Mg(BH4)(2)-based framework has been shown to significantly improve hydrogen desorption performance, reduce decomposition temperature and activation barrier, and prevent oxidation of the decomposed system.

Summary: Enhanced weathering is a strategy to remove carbon dioxide quickly, but its application in tropical peatlands may have negative consequences. Studies have shown that enhanced weathering might lead to carbon re-emission from soil and could potentially be offset by emissions from coastal waters.

Summary: In this study, a low-energy membrane emulsification process was developed for the preparation of water-in-oil (W/O) chitosan emulsions with a narrow droplet size distribution. The effects of emulsifier concentration, rotation speed, and chitosan concentration on droplet size and stability of emulsions were evaluated. The prepared emulsion showed a monodispersed pH responsive behavior with a droplet size of 300 ± 40 nm. The release of Vitamin B5 (calcium pantothenate) from the emulsion was temperature and pH dependent.

Summary: This study reveals the mechanism behind the viscosity increase due to emulsification in Jimsar shale oil using high-resolution mass spectrometry and computational methods. It suggests that N1 compounds in shale oil enhance its emulsification and water-binding ability, leading to the formation of stable W/O emulsion and increased fluid viscosity.

Summary: This study demonstrates a method of preparing low-density PDMS foams using water-based thixotropic fluids as porogens. The use of synthetic hectorite clay and nanocellulose as thixotropic fluids allows for the formation of fine emulsions with small droplet sizes. By carefully destabilizing the emulsion during the curing process of the PDMS matrix phase, foams with interconnected porosity, fast drying, and uniform porous structure can be obtained. These foams exhibit a range of mechanical properties and can achieve low densities and thermal conductivities.

Summary: Hydrogel-based microspheres were prepared using gelatin, paraffin oil, and Span 80, and the biocompatibility was improved by adding DAP or PC. DAP-modified microspheres showed better biocompatibility compared to PC. The microspheres degraded completely after 26 days in PBS. This drug carrier can be combined with other biomaterial matrices to achieve localized therapeutic effects and improve drug bioavailability.

Summary: Recently, Pickering emulsions stabilized by photocatalytic nanomaterials have attracted great attention in the field of catalysis due to their high interfacial activity. However, the hydrophilicity of most photocatalytic nanomaterials makes them inconvenient as stabilizers for Pickering emulsion construction. In this study, a novel magnetic Janus nanosheets (JMPSN/alpha-FeOOH) was successfully developed as an environmentally friendly Pickering emulsion emulsifier and catalyst. The JMPSN/alpha-FeOOH exhibited excellent emulsifying properties and significantly enhanced photocatalytic efficiency in degrading dyes compared to traditional non-emulsified systems, while maintaining the stability of Pickering emulsion under constant irradiation. Moreover, the JMPSN/alpha-FeOOH could quickly respond to external magnetic fields and retain high catalytic activity after multiple cycles.

Summary: A series of symmetrical lipids composed of dihydroxyacetone and even-carbon fatty acids were synthesized and formulated into porous microparticles without the use of additional porogens. The microparticle architecture was found to be lipid-length dependent, with organized patterns formed by the lipids. The release kinetics of a model drug was more greatly influenced by microparticle porosity and surface area than by the hydrophobicity of the lipids.

Summary: This article investigates the deformation of compound microdroplets transported inside a circular microchannel using numerical simulations. Two droplet morphologies (shell-core and Janus) are considered, and their behavior is analyzed in terms of flow rates, physical properties, and confinement conditions. The results show that the aspect ratio of the shell droplet in shell-core microdroplets decreases with the capillary number and droplet sizes, while sudden jumps occur when thin films form between the shell and core interfaces. Conversely, the aspect ratio of the core droplet in Janus microdroplets increases and then decreases with the flow and space confinements.

Summary: This paper proposes the concept of emulsification caused by fluid shearing and establishes an oil-water two phases flow model in porous media to study the generation process of emulsion under shearing action. The results indicate that complex flow between oil and water in porous media leads to shear emulsification of crude oil. The flow velocity and interface properties have an impact on the generation process of emulsion.

Summary: We developed a bent-capillary-centrifugal-driven (BCCD) monodisperse droplet generator that achieves driving and segmentation of the dispersed phase using a rotating bent capillary immersed in the continuous phase. The size and stability of the droplets can be conveniently controlled by the rotational speed of the bent capillary. The BCCD droplet generator has a high-efficiency sample utilization of 99.75 +/- 1.15% and can be easily constructed and operated, making it a valuable solution for droplet generation in biochemical applications.

Summary: The combination of air impingement drying (AID) and anaerobic digestion (AD) for treating common starfish was proved to be technically and economically feasible. In the most favorable case, the biogas heat generated from starfish could cover the heat demand for drying. Economic analysis showed that valorizing bio-methane through cogeneration or injection into the natural gas network could minimize treatment costs or even generate profits.

Summary: Poultry wastes can be used as substrates for biogas production, but the high protein content leads to ammonia inhibition. Different substrates and inoculum sources affect the biochemical methane potential, and increasing the substrate-to-inoculum ratio decreases the hydrolysis constant. Liger is the most suitable inoculum source. Comparing organic laying hen droppings with slaughterhouse waste, slaughterhouse waste is more important in anaerobic digestion due to its high methane yield, especially from viscera. Methane production is affected by increasing ammonia concentrations.

Summary: The objective of this study was to assess the impact of pulsed electric field (PEF) treatment on the extraction of polyphenolics and antioxidant activity from downgraded date palm fruits. The optimized PEF pretreatments significantly enhanced the polyphenol content, antioxidant activity, and phenolic profiles of the extracts obtained from the date fruits. PEF combined with thermal processing can be a suitable alternative treatment for extracting bioactive compounds from dates and food byproducts.
