Porous liquids represent a category of materials that combine the porosity of solid structures with the fluidity of liquids, drawing substantial research interest. In this work, we synthesized a novel class of porous carbon liquids, termed H-PLs, which exhibit stable flow at room temperature. This stability is achieved through cation-π interactions between an imidazolium-based polymeric ionic liquid ([EMIM][TF2N]) and a porous carbon network. Notably, the CO2 adsorption capacity of H-PLs reached 3.73 wt% at 298 K and 8 bar, significantly outperforming parent [EMIM][TF2N] ionic liquid and demonstrating a CO2 solubility approximately 37 times greater than that of N2 under identical conditions. These findings reveal the potential of H-PLs for selective gas adsorption, and suggest that electrostatic-assisted synthesis method offers a rapid, efficient and scalable pathway for future production of porous liquids.

We show in this paper that maximal Lq-regularity for time-dependent viscous Hamilton-Jacobi equations with unbounded right-hand side and superquadratic γ-growth in the gradient holds in the full range q>(N+2)[Formula presented]. Our approach is based on new [Formula presented]-Hölder estimates, which are consequence of the decay at small scales of suitable nonlinear space and time Hölder quotients. This is obtained by proving suitable oscillation estimates, that also give in turn some Liouville type results for entire solutions.

Membrane technology is a viable alternative for achieving energy savings and sustainability, particularly in dehydration applications. The selective removal of water vapor from gas mixtures by membranes enhances the process efficiency furthermore the industry increasingly prioritizes resource conservation and environmental impact, advancements in membrane technology are crucial for meeting these goals and driving progress toward a sustainable future. Our approach consists of the incorporation of a proline amino acid-based ionic liquid encapsulated in carbon capsules, dispersed in a Pebax®1657 matrix, and coated on polyetherimide hollow fibers. The filled capsules have high sorption capacity for both water vapor and carbon dioxide (CO2) contributing for successful exploration for air dehumidification, as well as flue gas, natural gas and biogas dehydration. The membranes had exceptional water vapor permeance, reaching values up to approximately 10,000 GPU while maintaining an H2O/N2 selectivity of around 124,000. CO2/N2 selectivity as high as 100 and promising results for CH4 purification were demonstrated. Long-term studies using alternative modules to prevent saturation of the encapsulated capsules with water vapor and effective regeneration have been proven.

Global climate change forces all countries to push the process of de-carbonization. Ammonia, which is carbon free and a potential hydrogen carrier, is proposed as a prospective fuel for the power devices to realize the green economy. It also exhibits very good fuel properties, including its storage condition, energy density. However, two main challenges, the difficulties of flame stabilization and potential high fuel NOx production, still need to be tackled in its application in gas turbines. In the last decades, valuable investigations were conducted to address characteristics of NH3/air flame stabilization in swirl combustors as well as the combustion enhancement by cofiring with active molecule like CH4 and H2, applying plasma assistance. These measures mainly improve the flame resistance to the flow and increase the key radicals at flame base, which may provide possible solutions to the combustion chamber design. The inherent mechanisms of fuel NOx production are highlighted by the HNO channel with the presence of OH radical. One promising strategy to mitigate NOx in gas-turbine like combustor is the staged combustion by staging the air or fuel, which may also fit for the practical combustion chamber. The high-pressure condition and plasma assistance were found to show positive influence on both flame stabilization and NOx control. This review also emphasizes the fundamental research issues for ammonia fuel and proposes some future research prospects towards the development of more robust, reliable, and low NOx combustion technologies relevant to gas turbines.
