Summary: Enhancing surface functional groups on biochar is crucial for improving its adsorption capacity towards toxic metals. The NaOH-C2H5OH modified biochar showed a higher specific surface area, more O-containing functional groups, and introduced more C=C groups, leading to enhanced adsorption properties, especially for Cd(II) and Pb(II). Spectroscopic analysis indicated that Cd(II)-pi and Pb(II)-pi interactions were the predominant mechanisms for the toxic metals' collection on the NaOH-C2H5OH modified biochar, with O-functional groups facilitating Pb(II) binding more effectively than Cd(II) in the mixture solution.

Summary: Physically blending semiconducting conjugated polymers with elastomeric materials and precisely controlling the resulting film structure provides an effective strategy to obtain intrinsically stretchable semiconducting polymers. The phase-separated ultrathin P3HT and SIS blend films maintain reproducible properties under 200 continuous stretch-release cycles at a strain of 50%, showing a balance between their mechanical and electrical properties. The deformability of the films is efficiently improved by blending, as demonstrated by both finite element analysis and dichroic ratio measurements.

Summary: This study investigated the removal of boron from model wastewater using PAdeCS, a material derived from waste concrete. Three different methods of boron removal were examined: adsorption with untreated PAdeCS, adsorption with heat-treated ettringite-enriched PAdeCS, and coagulation-sedimentation method. The coagulation-sedimentation method showed the highest boron removal performance, rapidly reducing the boron concentration in the wastewater to below the Japanese effluent standard. The heat-treated ettringite-enriched PAdeCS also exhibited improved boron removal compared to untreated PAdeCS.

Summary: The study focuses on the relationship between the structure and electrochemical performance of porous carbon nanofibers (PCNFs) derived from the biobased building block chitosan. The researchers found that by varying the amount and molecular weight of the sacrificial pore-forming polymer, they could tailor the structure of the PCNFs to have a high surface area and hierarchical pore network, resulting in fast ion diffusion, high specific capacitance, and rate capability. The chitosan-based materials demonstrated high stability and charge efficiency, making them promising for use in charge storage devices.

Summary: Ion-selective membranes are promising candidates for osmotic energy harvesting, but the fabrication of highly selective membranes is a major challenge. Metal-organic frameworks (MOFs) with well-defined nanochannels along functional charged groups can help overcome this problem. In this study, dense sodium polystyrene sulfonate (PSS) incorporated MOFs composite membranes (PSS@MOFs) were developed on a porous anodic aluminum oxide (AAO) membrane through in situ anodic electrodeposition. The sulfonated nanochannels of the PSS@MOFs composite membrane provided rapid and selective transport of cations, leading to high energy conversion efficiency and output power in osmotic energy conversion.

Summary: Understanding the ion transport in concentrated electrolytes is important. This study demonstrates an enhanced ion transport of water-in-salt (WIS) electrolytes in 2D nanochannel membranes. The mechanism involves a stratification process induced by functional groups, where a free anion layer moves between two continuous water-cation layers. Lithium-ion batteries with this confined electrolyte showed improved capacity and coulombic efficiency. This work provides new insights into the ion transport mechanism in nanoconfined concentrated electrolytes and offers strategies for designing high-performance and safe electrolytes for energy and environmental devices.
