Wastewater features-directed design of an adsorbent is promising but challenging strategy for sustainable remediation of actual bisphenol A (BPA)-polluted water. Herein, we report that the discarded cigarette butt-derived porous carbon (AC-800) exhibit high capacity (865 mg/g), rapid reaction rate (186.9 mg/g/min) and outstanding durability for adsorption of BPA. Different from the most reported carbon-based adsorbents, quantitative structure-activity relationship studies unveil that graphitic defect plays a crucial role in the improvement of adsorptivity. Further studies illuminate that π-π interactions, electrostatic attraction and hydrogen-bond interaction play a negligible role whereas long-range hydrophobic interaction synergized with short-range dispersion force make a substantial contribution to BPA adsorption on AC-800. Benefited from this unique adsorption mechanism, AC-800 features a remarkable anti-interference capability and realizes the efficient clean-up of BPA from actual wastewater with complex backgrounds. This work sheds new light on mechanistic insight into the BPA adsorption on carbon-based materials and develops a fit-for-purpose designed adsorbent toward green remediation of practical wastewater.

Electrochemical water splitting is a promising approach to convert renewable energy into hydrogen energy and is beneficial for alleviating environmental pollution and energy crises, and is considered a clean method to achieve dual-carbon goals. Electrocatalysts can effectively reduce the reaction energy barrier and improve reaction efficiency. However, designing electrocatalysts with high activity and stability still faces significant challenges, which are closely related to the structure and electronic configuration of catalysts.

Although membrane technology is widely used in different gas separation applications, membrane manufacturers need to reduce the environmental impact during the membrane fabrication process within the framework of the circular economy by replacing toxic solvents, oil-based polymers, and such by more sustainable alternatives. These include environmentally friendly materials, such as biopolymers, green solvents, and surfactant free porous fillers. This work promotes the use of environmentally sustainable and low toxic alternatives, introducing the novel application of cellulose acetate (CA) as a biopolymer in combination with dimethyl carbonate (DMC) as a greener solvent and different inorganic fillers (Zeolite-A, ETS-10, AM-4 and ZIF-8) prepared without the use of toxic solvents or reactants.

The preparation of food-grade oxidized starch with eco-friendly ozone (O) as oxidant is limited by low mass transfer and reaction efficiency. This study proposed a porous spontaneously polarized ceramic-reinforced O micro-nano bubbles (PSPC-OMNB) technology to prepare oxidized cassava starch (PSPC-OMCS). Meanwhile, reaction uniformity, physicochemical properties, and formation mechanisms were emphasized for comprehensive investigation.

Herein, we synthesized a novel injectable porous magnetic hydrogel (MHG) at room temperature using carboxymethyl chitosan (CMCS), polydopamine (PDA), sodium alginate (SA), polyethyleneimine (PEI) and copper ferrite (CuFeO) as building blocks. The CMCS and SA as monomers provided good film-forming and anti-fouling properties for MHG. The PDA-coated CuFeO as a cross-linking agent improved the homogeneity, adsorption and electrocatalytic performance of MHG, but also generated a macroporous hydrogel structure which was beneficial for sensing applications.

Glioblastoma, characterized by rapid proliferation and invasiveness, is largely resistant to current treatment modalities. A major obstacle is the blood-brain barrier (BBB), which restricts the delivery of therapeutic agents as well as the infiltration of effective immune cells into glioblastoma. In this study, we developed an injectable oxidized high-amylose starch hydrogel (OHASM) to serve as a biomaterial scaffold for the delivery of macrophages and macrophage-polarizing drugs, aiming to bypass the BBB and enhance glioblastoma treatment.
