Summary: Polyurethane foams are widely used as a biomaterial system due to their ability to tune physical, chemical, and biological properties. By adding ether-containing monomers, shape memory polymer foams with tunable degradation rates have been synthesized for longer-term stability in various biomaterial applications. These SMP foams have the potential to provide controlled erosion profiles and up to 15% mass remaining after 108 days when used in oxidative and hydrolytic media for in vitro degradation assessment.

Summary: In this study, the influence of D-lactide content of poly(lactic acid) and the presence and dosage of an expandable microspheres-type foaming agent on the compostability of polymeric foam samples was investigated. The results showed that poly(lactic acid)-based foam sheet with higher D-lactide content decomposed faster than the foam sheet with lower D-lactide content when 8 wt% foaming agent was applied. It was found that thermally expandable microspheres decreased the rate of degradation in poly(lactic acid)-based syntactic foam structures, but even the medium-density foams degraded before day 70.

Summary: This study found that iron-loaded biochars (FeBCs) can accelerate the simultaneous removal of nitrate and bisphenol A (BPA) from aquatic systems. FeBCs have high electron transfer efficiency and redox activity, which can enhance microbial metabolism and degradation ability. The addition of FeBCs increased the activity of denitrifying enzymes and the level of nitrate-reducing genes, as well as the abundance of bacterial genera responsible for BPA degradation. Moreover, the ferric-containing functional groups were significantly correlated with nitrate-reducing enzymes and metabolic activities, facilitating the simultaneous removal of nitrate and BPA.

Summary: Due to the diminishing energy resources and environmental pollution issues, direct methanol fuel cells (DMFCs) have gained a high profile in recent decades as a green energy generator. In this research, ultrasmall Rh nanocrystal-decorated heterostructures were designed and fabricated from Zn-based zeolites imidazolate frameworks (ZIFs) and Ti3C2Tx MXene nanosheets (Rh/ZIF-MX) via a bottom-up stereoassembly strategy. The resulting Rh/ZIF-MX nanoarchitectures exhibited superior electrocatalytic performance for methanol oxidation, surpassing traditional Rh catalysts directly supported on carbon materials.

Summary: Intimately coupled photocatalysis and biodegradation (ICPB) is an effective technology for removing refractory contaminants from water. In this study, a novel three-dimensional porous hydrogel carrier, BC/g-C3N4, was developed and used in the ICPB system for the first time. The ICPB system showed a significantly higher removal rate (96.0%) of tetracycline hydrochloride (TCH) compared to other systems. Photo-electrochemical tests confirmed the superior electron transfer ability of the ICPB system. Microorganisms played a crucial role in the mineralization process of TCH and remained active after the ICPB degradation experiment. The study highlights the potential of the novel ICPB carrier and system in practical applications.

Summary: Anthropogenic deoxygenation of freshwater systems has raised global concern due to its potential threats to biodiversity, nutrient loading, and greenhouse gas emissions. This study developed a new method using oxygen-carrying dual-modified sediment-based biochar to restore hypoxic freshwater and reduce methane emissions. The results showed that the modified biochar significantly increased dissolved oxygen concentration and decreased methane emissions. Microbial analysis indicated that the restored oxygen-rich environment promoted the expression of methane oxidation genes. The study highlights the potential of improving water quality and microbial community reconstruction in reducing greenhouse gas emissions.
