This shows that the neural progenitors retain their cellular self-organization ability in the FN-silk/LN-521-supported 3D culture. Calcium imaging demonstrated spontaneous activity, which is important for the formation of neuronal networks. Together, the results show that hPSCs integrated into FN-silk/LN-521 foam develop into neural progenitors and that these stay viable during long-term differentiations. FN-silk/LN-521 also supports morphogenesis mimicking the human brain development and can serve as base for engineering of hPSC-derived neural tissue.When a liquid drop sits on an atomically thin layer of a 2D van der Waals (vdW) solid (like graphene) supported by a hydrophilic material, it is possible that the drop demonstrates an equilibrium contact angle that is influenced by this underlying hydrophilic material and hence is different from that observed on the bulk 2D material (e.g., graphite) surface. Such a behavior is known as the wetting translucency effect. While the wetting translucency effect of graphene has been extensively studied, the wetting translucency of hexagonal boron nitride (hBN) remains largely unexplored despite significant similarities in structural properties between these materials. In this study, we probe the wetting translucency of hBN. For this purpose, we conduct molecular dynamics simulations of water droplets and water films on hBN layers supported on a gold-like hydrophilic substrate. Our results show that for a substrate coated by monolayer hBN ("coated substrate"), depending on the contact distance between underlying substrate and hBN, an increase in the hydrophilicity of the underlying surface causes a monotonic increase in the overall adhesion energy between water and the coated substrate and a monotonic decrease in the contact angle of a drop on the coated substrate. For an increasing number of stacked hBN layers, the wettability of coated substrate becomes independent of the wettability of the underlying solid. Accordingly, our results confirm a distinct wetting translucency nature of hBN very similar to that observed in graphene.Crystallographic orientation control is an effective method to improve the photoelectrochemical water splitting efficiency of BiVO4 photoanodes. Herein, textured and transparent Mo-BiVO4 photoanodes are fabricated by spin-coating Mo-doped BiVO4 nanoparticles on FTO. The photoelectrodes exhibit a current density of 4.15 mA cm-2 and 2.50 mA cm-2 for sulfite and water oxidation, respectively. By connecting the photoelectrode with a CsPbBrI2 perovskite solar cell, a stand-alone tandem water splitting device with a current density of 2.13 mA cm-2 and an STH of 2.43% can be achieved.Two new non-fullerene acceptors, namely QIP-4F and QIP-4Cl, containing a novel imide-functionalized quinoxaline (QI) moiety fused with a thienylthiophene unit as the central building block, and fluorinated or chlorinated 2-(3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile as end-capping groups, were designed and synthesized, respectively. An optimized device based on P2F-EHpQIP-4Cl presented a power conversion efficiency of 13.3%, with an impressively high open-circuit voltage of 0.94 V. These results demonstrate the great potential of QI-containing fused units as central building blocks for high-performance acceptors.Previous studies have shown that the plateau modulus Gp of the wormlike micelles formed in water driven by hydrophobic interactions is a constant upon heating, similar to polymer solutions, and Gp of the reverse worms formed in oils driven by hydrogen bonding decreases with increasing temperature. In this work, we investigated the reverse worms induced by three chloride salts that bind lecithin through different strengths of electrostatic interactions, in the order of LaCl3 > CaCl2 > LiCl. We correlated the interaction strengths with the temperature-dependent rheological properties and found that upon heating, Gp for all the reverse worms driven by electrostatic interactions decays slower than that driven by the weak temperature-sensitive hydrogen bonding. Furthermore, the decay rates of Gp follow an order in the inverse relation to the interaction strength, LaCl3≤ CaCl2 less then LiCl, indicating that the dependence of Gp on temperature can reflect the strength of the driving forces for micellization. We utilized Fourier transform infrared spectroscopy (FTIR) to confirm the weakening of the interaction and the small angle X-ray scattering (SAXS) technique to reveal the decrease in the lengths of the reverse worms as temperature increases, both of which echo the changes in the rheological properties.A water-soluble macrocyclic host is reported, composed of alkoxyanthracene as the donor (D), and 4,4-bipyridinium as the acceptor (A). The intramolecular D-A structure renders the host highly photostable. LCL161 However, the introduction of a strong electron-donating guest promotes the photodecomposition of alkoxyanthracene, yielding photolyzable host-guest complexes or aggregates.The cell membranes of different cells deviate significantly in lipid compositions and thus provide varying biological environments to modulate the diffusion, organization and the resultant function of biomacromolecules. However, the detailed modulation mechanism remains elusive especially in consideration of the current overuse of the simplified membrane models such as the pure phosphatidylcholine (PC) membrane. In this work, with the typical membrane-active peptide melittin, we demonstrated that a more complicated membrane environment, such as the bacterial (IME) or plasma membrane (PM), would significantly change the organization and dynamics of melittin, by using molecular dynamics simulations as a "computational microscope". It was found that in these membrane systems, adding melittin would cause a varying degree of reduction in the lateral diffusion of lipids due to the different assembly states of peptides. Melittin tended to aggregate to oligomers in the pure PC membrane, mostly as a tetramer or trimer, while in IME or PM, its degree of oligomerization was significantly reduced. More surprisingly, melittin displayed a strong affinity with ganglioside GM3 in PM, leading to the formation of melittin-GM3 nanoclusters, which hindered its diffusion and further oligomerization. Additionally, small changes in the residue sequence of melittin could modulate the degree or structure of the peptide oligomer. Our work provides a typical example of a study on the organization and dynamics of pore-forming peptides in specific membrane environments and has great significance on the optimization of peptide sequences and the design of helix bundles in the membrane for target biological function.
