Summary: Extensive 2-D platinum nanowire network (NWN) sheets are created through a hierarchical self-assembly process with the aid of biomolecular ligands. The Pt NWN sheet is assembled from the attachment growth of 1.9 nm-sized nanocrystals into nanowires featuring a high density of grain boundaries, which then interconnect to form monolayer network structures extending into centimeter-scale size. The Pt NWN sheets exhibit outstanding oxygen reduction reaction (ORR) activities, with specific and mass activities 12.0 times and 21.2 times greater than those of current state-of-the-art commercial Pt/C electrocatalysts.

Summary: Silver nanowire transparent conductive films (AgNW TCFs) were prepared by screen printing conductive ink on a PET substrate, and the effects of ink compositions and oily stencil on the optoelectrical properties of AgNW TCFs were investigated. The resulting AgNW TCFs exhibited low sheet resistance, high transmittance, and high uniformity, and could be patterned and personalized through the screen printing process.

Summary: This study demonstrates the orientation-controlled synthesis of the low-symmetry 2D material ReS2 for the first time through interface engineering based on the strong interaction between the material and Au substrates with different symmetries. The results show that the lattice orientation and growth behavior of ReS2 are closely relevant to the lattice symmetry of Au facets, and the critical factor for achieving its intrinsic anisotropic growth is the synergy of ultra-strong ReS2-Au interfacial coupling and reduction of symmetry of Au facet.

Summary: In this study, a dynamical model for dark energy based on an ultralight mass scalar field with large-scale inhomogeneities is considered. The model is found to have observable impacts on the anisotropic properties of the cosmic microwave background (CMB) intensity and luminosity distance. Numerical solutions show that the model can mimic the standard ΛCDM cosmology, including spatially dependent dark energy with flexible ranges of model parameters. Constraints on the amplitude of these inhomogeneities are also put forward through observations of the CMB anisotropies, along with discussions on their influence on the estimation of the luminosity distance.

Summary: A novel self-assembly technique called suspending self-assembly method (SSAM) was proposed for fabricating three-dimensional colloidal crystals. By manipulating electrostatic intersphere repulsive forces, a variety of polystyrene (PS) colloidal crystals with different diameters can be prepared. The major driving force for successful ordering process is found to be electrostatic repulsive forces between PS microspheres, rather than capillary forces. This work has the potential to revolutionize the current preparation techniques of colloidal crystals.
