A (11) mixture of ANXA4 and ANXA5 induces membrane rolling with a time constant intermediate between the value for the pure annexins. While binding of the pure annexins creates crystal lattices, the (11) mixture generates a random arrangement of trimers. Thus, curvature induction remains as a functional property of annexin mixtures in PMR rather than crystal formation.

ANXA4 and ANXA5 colocalise at the damage site of MCF7 cells during repair. A (11) mixture of ANXA4 and ANXA5 induces membrane rolling with a time constant intermediate between the value for the pure annexins.

However, it always faces several restrictions including severe photocorrosion, low charge separation and transfer efficiencies, poor visible light harvesting, and sluggish interfacial reaction kinetics, which often required a variety of modifications with only low improvements achieved. Herein, a high performance CQDs/TiO2/WO3 photoanode was designed on the basis of density function theory (DFT) alignment of lattice parameters and energy band, and charge distribution. The TiO2/WO3 heterojunction can abate photocorrosion through the hetero-epitaxial growth of TiO2 (001) on WO3 (002) for the lattice mismatch less then 3% eliminating dangling bonds, with high corrosion resistance and photostability of TiO2. As the built-in field constructed by a staggered band alignment structure with the valence band offset (VBO) of 0.51 eV, the photogenerated carriers transfer and separation are promoted dramatically. Through the DFT calculations, the sunlight absorption wavelength can be extended, and the interfacial reaction kinetics can be expedited with the modification of carbon quantum dots (CQDs) on TiO2/WO3, due to the narrower bandgap (Eg) and the accumulation of electrons at TiO2 side. The DFT designed CQDs/TiO2/WO3 photoanode significantly increase photocurrent density from 0.90 to 2.03 mA cm-2 at 1.23 V, charge separation efficiency from 56.3 to 79.2% and charge injection efficiency from 51.2 to 70.4%, and extend light absorption edge from 455 to 463 nm over pristine WO3, with better photostability and lower holes-to-water resistance.We report CoFe2O4 and carbon nanotubes hybrid aerogels as a novel anode material for potassium ion batteries (KIBs). The synthetic route take the advantage of marine biobased materials as the precursor and facilely produce large-scale production of hybrid CoFe2O4 and carbon nanotubes aerogels as the advanced anode. The hybrid aerogels deliver a remarkable capacity of 180 mAh g-1 with high stability over 200 cycles at a current density of 0.1 A g-1. The high rate charge/discharge reveals a relatively high capacity of 83 mAh g-1 even at the current density of 1.0 A g-1. In-situ XRD investigations reveal the phase evolution during charge/discharge, demonstrating the high stability of hybrid aerogels for the potassium intercalation/extraction. The high specific surface area and large numbers of mesopores with more active sites can benefit the effective transmission of electrons and K ions, leading to an improved specific capacity and cycle stability.Patchy micelles of diblock copolymers can be polymerized into a linear supracolloidal chain. We measure the persistence and contour lengths of supracolloidal chains coated on a solid substrate to evaluate their flexibility. Based on the analysis, the chain is semi-flexible, and the conformation is suitably explained by the worm-like chain model. In addition, utilizing a spin-coating technique with the semi-flexible nature of the chains, we produce a self-supporting film of supracolloidal chains having nanoscale pores essentially from colloidal constituents that tend to form dense packing if there is no prior organization of them into a semi-flexible chain.The design and development of high-performance photocatalysts from three aspects of simultaneous enhancement of light harvest, carrier migration rate, and redox reaction rate is still a great challenge. Herein, a novel Co9S8/CdIn2S4 ohmic junction with a robust internal electric field (IEF) is successfully prepared via hydrothermal and in situ synthesis methods and is used for effective photocatalytic H2 evolution (PHE). Under simulated visible light irradiation, the PHE rate of 5% Co9S8/CdIn2S4 can reach 1083.6 μmol h-1 g-1, which is 6.4 times higher than that of CdIn2S4 (170.5 μmol h-1 g-1). The enhanced PHE performance is mainly ascribed to the improved light harvest and carrier separation efficiency and fast surface H2 evolution kinetics. TPEN Moreover, Co9S8 nanotubes serve as promising Co-based cocatalysts that can evidently enhance PHE activity. Additionally, Co9S8/CdIn2S4 shows superior stability because the photogenerated carrier transfer path restrains the photocorrosion behavior. The photocatalytic mechanism is proposed based on experimental results and DFT calculations. This work offers new insights for the design and development of highly active photocatalysts from interface engineering.Designing a novel composite material with hierarchical nanostructures as a negative electrode material with high capacitance and outstanding stability is challenging. To this end, we synthesized carbon nanotubes (CNTs)-protected vanadium phosphate (VPO) nanoparticles trapped within an electrospun carbon matrix (CNTs@VPO@CNFs) for potential use in energy storage applications. Temperature was found to be the major controlling factor for the fabrication of composites with CNT decoration. CNTs@VPO@CNFs exhibited the highest capacitance of 576.1F g-1 at a current density of 0.66 A g-1 among other corresponding electrode materials. Furthermore, this electrode exhibited outstanding stability of up to 99% after 5000 cycles, which was attributed to the coating of core-forming VPO@CNFs by the CNTs as the sheath material. Interestingly, the as-fabricated material worked in a wide potential range from -1.2 to 0.6, thereby providing the opportunity to assemble a symmetric supercapacitor device (SSCD). The SSCD showed an exceptionally high energy density of 69.
