[Display omitted] • A synergistic combined strategy with quinolinic acid (QA) and DMF was developed. • A multi-passivation mechanism of QA was investigated. • The high-quality perovskite films with grain size over 1 µm were formed. • A champion device with undoped PEDOT:PSS with a PCE of 18.56% was fabricated. We developed a new combined method in which quinolinic acid (QA) passivation and DMF solvent annealing are carried out sequentially to enhance the performance of inverted perovskite solar cells. Upon systematic investigation, we found that: 1). One QA molecule not only passivates more than one defects within lattice or neighboring lattices, creating a multi-passivation effect, but also enhances the interactions between lattices, due to pyridine ring and dicarboxylic acid functional groups in the molecule; 2). By combining with DMF solvent annealing post-treatment sequentially, high quality perovskite films with very large grain size over 1 µm are obtained on the substrate of PEDOT: PSS. As a result, the PSC fabricated with the combined method demonstrates an excellent humidity stability and yields a PCE of 18.56% with 20% and 11.6% increment of V oc and J sc , respectively. To the best of our knowledge, it is the highest reported PCE for inverted PSCs with undoped PEDOT:PSS as hole transporting layer. Therefore, our work indicates that the combined strategy of multi-passivation with QA and solvent annealing with DMF sequentially has a significant potential for highly-efficient and stable inverted planar PSCs.

[Display omitted] • Paper-based cascade sensitized structure of CuInSe 2 /Cu 3 (BTC) 2 /Y:ZnO was assembled. • The entropy-driven SDA propelled DNAzyme roller amplification strategy was designed. • Surface plasmon resonance-enhanced cascaded sensitization effect was proposed. Herein, the surface plasmon resonance (SPR)-enhanced cascaded sensitization effect of CuInSe 2 /Cu 3 (BTC) 2 /yttrium doped ZnO (Y:ZnO) photosensitive structures were integrated on lab-on-paper photoelectrochemical (PEC) biosensing platform for the ultrasensitive detection of microRNA-21 (miRNA-21) based on entropy-driven strand displacement amplification (SDA) propelled DNAzyme roller amplification strategy. The Y element doping equipped the paper-based Y:ZnO nanorods with enhanced PEC performance, which was further cosensitized with Cu 3 (BTC) 2 metal-organic framework (MOF) and CuInSe 2 quantum dots (QDs), giving a cascaded sensitization effect for generating a robust and stable photocurrent signal. The SPR effect between CuInSe 2 QDs and Au nanoparticles (NPs) was activated with the aid of entropy-driven SDA propelled DNAzyme roller amplification-induced conversion of target miRNA-21 to Au NPs-labelled track DNA (track DNA-Au), which could effectively promote the photogenerated carrier separation and transfer of CuInSe 2 /Cu 3 (BTC) 2 /Y:ZnO cascade sensitized structures via hot-electron transfer mechanism, further enhancing the photocurrent signal. Based on this designed "signal-on" mode, the quantitative detection of miRNA-21 was achieved with high sensitivity, good specificity, and excellent practicability, which provided a promising model for developing lab-on-paper diagnostic tool for biomedicine.

• Fabrication of slippery coating without loss of lubricant. • The resistance to the loss of lubricants. • Quantum chemical calculation of interaction energy between silicone oil and polyorganosilazane molecules. • The better anti-icing and anti-corrosion ability. Inspired by Nepenthes pitcher plant, slippery liquid-infused porous surface (SLIPS) has been received great concern. However, the fabrication and application of SLIPS generally cannot avoid the complicated construction of the micro/nanostructures and the loss of the lubricant. In addition, despite another slippery covalently surface can exhibit liquid-like properties of SLIPS, the chemical grafting reaction conditions are usually harsh and low-efficiency. To address these challenges, herein an easy, high-efficiency and non-fluorinated strategy to create a flat slippery coating without the loss of lubricant (SCLL) was reported. The better flatness and the own hydrophobicity of the cured polyorganosilazane (PSZ) combined with the silicone oil molecules on its surface endowed the SCLL excellent slippery property. Moreover, the strong intermolecular attraction and the large adhesion work originated from the chemical affinity between PSZ and silicone oil molecules allowed the proposed SCLL with no lubricant loss. We further showed the SCLL has promising application prospects in the ice resistance, indicated by its longer icing-delaying time and lower ice adhesion strength, compared with original Al surface. Our envision is that SCLL may be applied in the practical industry production. [ABSTRACT FROM AUTHOR]

[Display omitted] • A new synergistic emulsification mechanism of O/W Pickering HIPEs was proposed. • A green and eco-friendly hydrogel with hyperbranched imprinted sites was designed. • The sorbents exhibit rapid capture kinetics, high absorption capacity and excellent selectivity. • A lasting adsorption stability were realized in practical samples. Hyperbranched sorbents has attracted extensive concern from scholars at home and abroad owing to its rich surface termination recognition units and hyperbranched crosslinking structure. In this work, a new kind of porous hyperbranched boronate affinity molecularly imprinted hydrogel (PHs@CNCs@Y-Br-MIPs) were prepared via Pickering emulsion template method for selective separation and purification of flavonoids in complex agricultural wastewater. The novel multi-response hyperbranched Pickering particles based on cellulose nanocrystals (CNCs) can effectively enhanced the biocompatibility, hydrophilic, and interface stability of the emulsion system. Meanwhile, the introduction of dipentaerythritol hexyl (3-mercaptopropionic acid) (DH) in CNCs@SH@Y-Br could provide abundant hyperbranched anchor groups for immobilizing template molecules, resulting in the formation of more specific binding sites. In addition, the 4-formyl-1,2 phenylbis (2-bromo-2-methyl protocarbamate) (Y-shaped initiator) can precisely regulate the distribution of imprinted site and imprinted efficiency via atomic radical polymerization (ATRP). As expected, the resulting PHs@CNCs@Y-Br-MIPs showed fast adsorption kinetics (360 min) for NRG under pH = 7.4 and the excellent NRG adsorption capacity (Q max = 42.28 μmol g−1). Compared to non-imprinted polymer, the PHs@CNCs@Y-Br-MIPs exhibited the promising imprinting factors (IF = 2.74) owing to the abundant boronate affinity sites numbers of 46.81 μmol g−1 and the high-affnity binding site density of 0.56 μmol/m2 on PHs@CNCs@Y-Br-MIPs. The adsorption–desorption cycles proved excellent regenerability (only 6.79 % loss) after six adsorption–desorption cycles. Furthermore, the NRG extraction rate of PHs@CNCs@Y-Br-MIPs increased to 93.61 %. The purified NRG had good antibacterial properties against Staphylococcus aureus (13.17 mm of antibacterial bands). As such, the ability to hyperbranched imprinted polymers-regulate the recognition site density and selectivity highlights their significance in functioning as smart porous imprinted sorbents for separation and purification of targeted flavonoid molecules.

• An innovative emulsion interfacial assembly imprinted strategy was designed. • The optimized adsorbent has excellent biocompatibility and mechanical ability. • Hyperbranched imprinted sites facilitate NRG adsorption at multicomponent extract. • The outstanding adsorption selectivity in practical natural products can be enabled. Hydrogel-based molecular imprinted materials have attracted much attention in separation science and technology. However, traditional hydrogel imprinting sorbents face the limited number of imprinting sites, resulting in low adsorption capacity. Herein, a novel hyperbranched boronate affinity imprinted hydrogel (APOH-BA-MIPs) was prepared based on emulsion microreactors for the specific separation of flavoniods. Interestingly, the new Pickering particles (CNCs@GMA@SH-A-CD) with hyperbranched anchor groups and suitable hydrophilic properties were fabricated, which significantly grafted the specific recognizing sites. Meanwhile, the cellulose nanocrystals (CNCs) and cyclodextrins (CDs) composite can effectively enhance the emulsion stability. The addition of functioned CNCs solid emulsifier would effectively enhance the mechanical stability of micro-nano imprinting assembly sorbents during the adsorption process. The mechanical properties of the resulting APOH-BA-MIPs were also improved (Young's moduli 1.73 MPa). The results of adsorption experiments of APOH-BA-MIPs show fast adsorption kinetics (300 min) for NRG under pH = 7.4. The APOH-BA-MIPs still exhibited a significant adsorption capacity (56.03 μmol g−1 at 308 K) for NRG compared to other structural analogues, such as CC, RT, QRCT, ARS and LTL. The imprinting factor (IF) of 3.24 was observed for APOH-BA-MIPs compared to their non-imprinted counterpart. The high affinity site number of APOH-BA-MIPs were calculated to be as high as 53.11 μmol g−1. The regeneration performance of APOH-BA-MIPs still remained at 93.75 % after seven adsorption–desorption cycles. Additionally, the purity can be extracted from agricultural waste pomelo peel to 91.37 %. The purified NRG exhibited excellent antibacterial properties against Staphylococcus aureus. This work provides a new strategy for the fabrication of micr-nano imprinted sorbents with abundant and uniform recognition sites for specific capture flavonoid molecules from agricultural waste.
