Summary: The removal of organophosphorus (OP) herbicides from water has been studied using various methods such as adsorptive removal, chemical oxidation, electrooxidation, enzymatic degradation, and photodegradation. In this study, a Zr-based metal-organic framework (mCB-MOF-2) was used for the adsorption and photodegradation of the OP herbicide glyphosate (GP). The mCB-MOF-2 demonstrated a high adsorption capacity for GP and selectively converted it to non-toxic sarcosine and orthophosphate under UV-vis light irradiation. These findings suggest that mCB-MOF-2 is a promising material for removing OP herbicides from water.

Summary: A novel method was found to synthesize anhydride-terminated imide oligomer containing phosphorus and fluorine (FPI), which can be used as co-curing and flame-retarded agents to improve the overall properties of epoxy thermosets. The performance of EP/FPI-3 was enhanced after flame retardancy, with increased glass transition temperature, heat deflection temperature, 5 wt% mass loss temperature, Young's modulus, and decreased dielectric constant, dielectric loss, and water absorption.

Summary: The stability of organic solar cells is crucial for their commercialization. This study investigates the thermal degradation of inverted photovoltaic devices based on the PM6:Y6 non-fullerene system and identifies trap-induced transport resistance as the primary cause of the drop in fill factor. By suppressing trap formation, device lifetimes could be significantly increased, offering a promising future for organic solar cells.

Summary: The degradation mechanism of PE oligomer by P450 BM3 variant was explored using molecular dynamics simulations and quantum mechanics/molecular mechanics calculations. It was found that the degradation involves hydrogen abstraction and rebound processes, with hydrogen abstraction being the rate-determining step. The study also revealed regio- and stereoselectivity during the degradation process, and identified key structural parameters that greatly influence PE degradation efficiency. The degradation process of PVC oligomer was also investigated, showing differences in the catalytic energy landscape compared to PE oligomer. Overall, these findings provide an environmentally friendly strategy for the removal of PE and PVC waste.

Summary: To address the challenges of demanding synthetic conditions and poor stability of low ceiling temperature (Tc) polymers, the authors propose developing high-Tc polymers that can be converted into low-Tc polymers on demand. They demonstrate the mechanochemical generation of 2,5-dihydrofuran polymer (PDHF), which is otherwise difficult to synthesize, highlighting the power of polymer mechanochemistry. This concept can be applied to develop next-generation sustainable plastics.

Summary: The visible-light-induced photoreduction of carborane phosphonium salts under blue light irradiation provides a simple and effective method for accessing carbon-centered carboranyl radicals without the use of transition metals and photocatalysts. The utility of this method is demonstrated by the successful preparation of carborane-oxindole-pharmaceutical hybrids through radical cascade reactions. Computational and experimental studies suggest that the carbon-centered carboranyl radicals are generated through single-electron transfer of photoactive charge-transfer complexes between the salts and the additive potassium acetate.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
