Summary: Extracting osmotic energy through nanoporous membranes is an efficient way to harvest renewable and sustainable energy using the salinity gradient between seawater and river water. A lamellar-structured membrane made of nanoporous Ti3C2Tx MXene sheets is reported in this study, showing simultaneous enhancement in permeability and ion selectivity. The constructed internal nanopores lower the energy barrier for ion passage, thereby boosting preferential ion diffusion across the membrane. This membrane design strategy using nanoporous two-dimensional sheets provides a promising approach for ion exchange, osmotic energy extraction, and other nanofluidic applications.

Summary: Nitrogen-doped hierarchical porous carbon (N-HPC) was prepared from houttuynia cordata through chemical activation and nitrogen-doping. The etching behavior of the activator was enhanced by nitrogen doping, promoting the proportion of pyridinic and pyrrolic nitrogen. The prepared N-HPC exhibited a high specific surface area and nitrogen atoms mainly existed in the form of pyridinic and pyrrolic nitrogen. The N-HPC electrode showed a high specific capacitance and good rate characteristic, and the assembled symmetric supercapacitors achieved a high energy density. This work reveals the interaction between nitrogen-doping process and etching behavior, providing a novel route for biomass-based carbon material synthesis for supercapacitors.

Summary: Forward osmosis membrane bioreactors (FOMBRs) are gaining attention for their potential to produce high effluent quality and better flux stability against fouling. This study found that a hybrid cleaning strategy involving physical and free nitrous acid (FNA) cleanings can effectively recover water flux and slow down fouling deposition during long-term FOMBR operation. The results suggest that FNA solution has the potential to not only recover membrane performance, but also to act as a strategy to mitigate fouling deposition.

Summary: This study investigates the application of tubular polyetherimide (PEI) membranes prepared by dip-coating and multilayer assembly techniques in CO2 and H2 transport and CO2/N2 and H2/N2 selectivity. The results show that the permeability and selectivity of the membranes depend on the deposition cycle during dip-coating. For binary gas mixture separation, 100% CO2 and H2 purity is achieved regardless of the feed gas concentration. The PEI membrane exhibits interfacial confinement phenomenon, and the subtle change in imide group conformation contributes to increased polymer amorphicity and exclusive H2 and CO2 transport.

Summary: Traditional discussions about energy, CO2 emissions, and human development often overlook the inequality in domestic energy and CO2 emissions. This study reveals these inequalities in India and examines the impact on both welfare and CO2 emissions as India transitions away from energy poverty. The results suggest that addressing welfare issues related to energy use, such as indoor air pollution, can be aided by a transition to modern energy carriers without a significant increase in CO2 emissions. However, the wealth creation required for a modern energy transition will lead to increased consumption, supported by carbon-intensive electricity and materials, which represents the fastest-growing source of CO2 emissions. Consequently, a coherent strategy is necessary to tackle energy poverty, wealth creation, and reduce emissions intensity in sectors like transportation.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
