So far, the durability of these surfaces remains to be a major concern, preventing their adoption in practice. Here, we design a low-surface-energy framework of bridging rigid nanoparticles that can be covalently bonded together controllably, leading to the densification of the coatings and removal of the pores. The obtained compact and superhydrophobic coatings couple high mechanical strength and flexibility, endowing them to maintain superhydrophobicity and slippery properties despite being exposed to harsh abrasion of the surface. Under the binary cooperative strategy of superhydrophobic and slippery properties, our framework coatings are ultra-durable for icephobicity. Importantly, the versatile and scalable design of the framework coatings presented here provides a generic paradigm for coupling high mechanical strength and flexibility in one coating.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"7 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These asymmetric D-A acceptors, with one terminal group removed based on a same π-conjugated backbone, exhibit blue-shifted complementary absorption and shallower energy levels compared to symmetric A-D-A acceptors (Y6). Additionally, they show good miscibility with the A-D-A type Y6, forming an alloy-like phase with Y6 that features an elevated conduction band and enhanced molecular packing through stronger dipole–dipole interactions. This leads to significant improvement in the photoelectrical characteristics of OSCs and reduced dark current in OPDs. As a result, the ternary OSC with A-YBO-2Cl achieves a power conversion efficiency of 18.37 %, surpassing the 16.95 % of the binary device. Additionally, the ternary OPD with A-YBO-2Cl shows a significantly lower dark current density of 1.06 pA cm⁻² at V → 0 V and a higher specific detectivity of 6.14 × 10¹² Jones at 808 nm compared to its binary counterpart. These findings demonstrate that combining asymmetric D-A and symmetric A-D-A acceptors with a same conjugated framework effectively controls miscibility, energy levels, morphology, and performance in both OSCs and OPDs, offering a promising strategy for advancing organic semiconductor technology.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"113 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process demonstrated rapid degradation of persistent organic pollutants, such as carbamazepine (CBZ), diclofenac (DCF), and tetracycline (TC). For the degradation of ibuprofen (IBP), the E-PM-PMS process showed the highest mineralization ratio (55.76 %) and the lowest energy consumption (8.930 kWh m⁻³) within 120 min, compared with the PM-PMS (25.93 %, 61.814 kWh m⁻³) and E-PMS (31.07 %, 67.903 kWh m⁻³) processes. Mechanism studies indicated that the introduction of an electric field could promote the Mn(VII)/Mn(VI) cycle to form more permanganate (VI) complexes, resulting in the generation of more active species. Additionally, the MnO₂ produced in large amounts during the reaction could activate PMS to generate active species through the Mn(III)/Mn(IV) cycle, while also being activated by these active species to form Mn(V) and Mn(VI). Both the electric field and PMS reacting with PM led to the formation of various RMnS species (Mn(VI)_aq, Mn(V)_aq, Mn(IV)_s, and Mn(III)_aq). Through radical scavenging, electron paramagnetic resonance (EPR) experiments, it was proved that the degradation of IBP was mainly driven by reactive radicals, which are <span><span><math><msubsup is=\"true\"><mtext is=\"true\">SO</mtext><mrow is=\"true\"><mtext is=\"true\">4</mtext></mrow><mrow is=\"true\"><mo is=\"true\">∙</mo><mo is=\"true\">-</mo></mrow></msubsup></math></span><script type=\"math/mml\"><math><msubsup is=\"true\"><mtext is=\"true\">SO</mtext><mrow is=\"true\"><mtext is=\"true\">4</mtext></mrow><mrow is=\"true\"><mo is=\"true\">∙</mo><mo is=\"true\">-</mo></mrow></msubsup></math></script></span> (72.24 %) and ^•OH (12.38 %).

Herein, we developed a MnO₂-based bioresponsive nanoplatform (PIM NPs) that exerted multi-enzyme activities and synergized mitochondrial metabolism modulation for amplified PT and chemodynamic therapy (CDT) of melanoma. The PIM NPs were constructed by coating the MnO₂ nanozymes shell onto mesoporous polydopamine nanoparticles (mPDA NPs) loaded with photosensitizer (ICG). The PIM NPs consumed H₂O₂ to generate O₂ under acid TME, alleviating hypoxia to promote the photodynamic effect of ICG for producing toxic singlet oxygen (¹O₂). Meanwhile, the PIM NPs depleted glutathione (GSH) and triggered the Fenton-like reaction to destroy the antioxidant defense of the tumor cells. The photothermal property of mPDA NPs further enhanced the multi-enzyme activity and the effect of PT. Finally, the bioresponsive PIM NPs down-regulated glycolysis metabolism and oxidative phosphorylation, which disrupted the energy production and nutrient supply of tumor cells, causing the metabolic disorders of tumor cells. Both in vitro and in vivo results showed significant tumor inhibition, indicating that the PIM NPs achieved “All In One” strategy that combining tumor cell mitochondria metabolic regulation to amplify the effect of PT and CDT for melanoma, providing a promising integrated strategy against metabolic abnormalities of melanoma.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"97 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their practical application is limited by high conductivity, poor impedance matching, and low chemical stability. To mitigate these drawbacks, multifunctional Cu@ammonium gluconate core–shell nanofibers (Cu@AG CSNFs) are prepared via a simple one-step hydrothermal reduction, in which AG shell thickness and defects are adjusted by a competitive growth between AG shell and Cu core at various temperatures. Benefiting from the electron/phonon co-transmission and continuous 3D crosslinked framework, the Cu@AG CSNFs/TPU films exhibit a large thermal conductivity (23.07 W/(m⋅K); 8 wt%), high strength, excellent elasticity, and effective waterproofing. Meanwhile, the film of Cu@AG CSNFs can function as a Joule heater thanks to its fast thermal response, terrific working stability, and excellent repeatability. Besides, the Cu@AG CSNFs possess prominent microwave absorption capability (ABW = 6.24 GHz; 8 wt% load) and stealth performance, resulting from the synergic effect of heterointerfaces, tunable defects, and 1D structure. These properties exceed those of other Cu-based composites.

Batch adsorption studies explored the effects of pH, contact time, and initial dye concentration. The experimental data fitted well with the pseudo-second-order kinetic model, suggesting chemisorption as the primary mechanism, while equilibrium adsorption results fitted to the Langmuir isotherm model, described monolayer adsorption displaying the highest adsorption capacity (106 mg/g). A fixed-bed column experiment further demonstrated effective removal of methylene blue (MB) dye, achieving an initial breakthrough time of approximately 12 h, and exhibiting an adsorption capacity (q_e = 71.14 mg/g) surpassing batch adsorption capacity at the same concentration (q_e batch = 52.53 mg/g), signifying the practical utility of the materials. In addition, pyrolysis-derived biochar samples displayed improved total organic carbon (TOC) removal efficiency, with P-Cell-MOF achieving 93 % TOC removal. Density functional theory (DFT) calculations were employed to investigate the binding of MB on the various materials derived from the pyrolysis of cellulose with MOF.
