Our results, beside a quantitative agreement with experiments, show that the overall observed mobilities result from the competing packing mechanisms of the constituting units within the dyad both in the case of crystalline and amorphous phases. As a consequence, not all stable polymorphs have the same efficiency in transporting holes or electrons which often results in a highly directional carrier transport that is not, in general, a desirable feature for polycrystalline thin-films. The present work, linking microscopic packing to observed transport, thus opens the route for the in silico design of new dyads with enhanced and controlled structural and electronic features.Transformation between 2D covalent organic frameworks (COFs) via exchange of molecular building blocks with different symmetries has been realized, which gives rise to the conversion between 2D COFs with distinct pore hierarchy. #link# This type of monomer replacement has expanded the scope of the building-unit-exchange-based COF-to-COF transformation strategy.A slippery liquid-infused porous surface (SLIPS) is able to improve the hemocompatibility of implantable medical materials, which have saved countless lives. However, the preparation of a SLIPS on an implantable metal substrate (especially NiTi alloys) is still a substantial challenge because of the great difficulty of forming abundant porous microstructures on hard metals. In this paper, a novel strategy to prepare a SLIPS on a NiTi alloy substrate is reported. We used the laser pulse train of a femtosecond Bessel laser rather than the common Gaussian beam to directly create deep porous microstructures on the surface of the implantable NiTi alloy. Based on the laser-induced porous microstructure, the SLIPS was obtained by lowering the surface energy and infusing the lubricant liquid into the pores. The as-prepared SLIPS very effectively repelled water and blood. The hemocompatibility of the NiTi alloy was greatly improved after the formation of the SLIPS by the femtosecond Bessel laser processing. It was demonstrated that the SLIPS gives the NiTi alloy a remarkable anticoagulation property, very low hemolysis rate, and antibacterial property. We believe that the laser-induced SLIPS will accelerate the broad application of metal implants in the medical field in a healthier and safer way.As one of the most malignant primary cancers, hepatocellular carcinoma (HCC) still lacks an efficient therapeutic strategy to date. Here, we developed a polymer-based nanoplatform PEI-βCD@Ad-CDM-PEG (PCACP) for functional microRNA (miRNA) therapy. PCACP exhibits excellent stability in physiological solutions, but sensitive PEG detachment and size transformation in an acidic tumor environment due to the breakdown of pH-responsive linkages, promoting tumor penetration and cellular uptake of nanoparticles, further facilitating transfection efficiency due to the proton sponge effect of polycations. We present a novel miRNA cocktail therapy by encapsulating miR-199a/b-3p mimics (miR199) and antimiR-10b (antimiR10b) into PCACP for eliminating HCC. Validated by qRT-PCR, immunoblotting and immunohistochemistry, compared with miR199 or antimiR10b delivered alone, miR-cocktail therapy substantially inhibits HCC cell proliferation and tumor growth by targeting mTOR, PAK4, RHOC and epithelial-mesenchymal transition (EMT) pathways both in vitro and in vivo (i.v. injection). Furthermore, we proposed personalized miR-cocktail therapy by adjusting the encapsulated miRNA formula according to the miRNA profiling of a patient's tumor sample. The personalized PCACP/miR-cocktail system exhibits significant tumor suppression and multitarget regulation on patient derived xenografts (PDXs), representing a notable effect improvement over conventional gene therapy. The tumor-acidity-cleavable PCACP/miR-cocktail system, with loaded miRNA controllability and high transfection efficiency, is a promising personalized therapeutic strategy for future HCC treatment.Correction for 'Recent developments in the synthesis and applications of chiral ferrocene ligands and organocatalysts in asymmetric catalysis' by Laura Cunningham et al., Org. Biomol. Chem., 2020, DOI 10.1039/d0ob01933j.Mixed-anion compounds are among the most promising systems to design functional materials with enhanced properties. Among the phosphate-sulfate species, the [SO4]2- and [PO2F2]- tetrahedra are known and give rise to structural versatility. However, to date, the crystal structures of phosphate-sulfates with the coexistence of two distinct anion groups ([S2O7]2- and [PO2F2]-) in one compound are unknown. Here, a novel type of fluorooxophosphorsulfate, K4(PO2F2)2(S2O7) (KSPOF), is designed and synthesized via a high-temperature method in a closed system. The crystal structure is derived from single-crystal X-ray diffraction (C2/c, a = 13.000(10) Å, b = 7.5430(10) Å, c = 19.010(10) Å, β = 130.070(10)°, and Z = 4). Danusertib is the first fluorooxophosphorsulfate with mixed-anion building units ([S2O7]2- and [PO2F2]-) and a unique drum-like cluster was found, which enriches the diversity of structures for fluorooxophosphorsulfate systems. Furthermore, the theoretical calculations indicate that KSPOF possesses moderate birefringence, which mainly originates from the distorted [PO2F2]- tetrahedron.Molecularly imprinted polymers (MIPs) are a fascinating technology for the sensitive and selective detection of target molecules. However, in most situations, the need for complicated and expensive analytical devices for reading the responses of MIPs greatly limits their applications. For exploring low-cost and easy-to-use applications of MIPs, herein we have developed a MIP-modified extended-gate type organic field-effect transistor (MIP-OFET). Taurine was selected as a demonstrative analyte due to its biological roles and utility as a nutrient. We explored the rational design of the novel MIP with the aid of density functional theory and wave function calculations and characterized the electrochemically synthesized MIP using differential pulse voltammetry and electrochemical impedance spectroscopy. The mechanism of taurine detection by the MIP-OFET can be explained by the changes in the surface potential of the MIP-functionalized extended-gate electrode accompanied with the capture of taurine. The detection limit of taurine in complete aqueous media was estimated to be 0.
