Coordination-driven self-assembly has led to the formation of various aesthetical polyhedrons and compounds with advanced functions. Whereas two-dimensional supramolecules with complex and giant skeletons are plentiful, the constructions of polyhedrons are limited by using basic polygons as the panels. Herein, we report the modular synthesis of a tessellated triangle and tessellated octahedron with metal-organic modules as the panels and formed via template-driven self-assembly. These architectures have diameters on the order of 10.9 nm and molecular weights greater than 84 kDa. Interestingly, fiber and spherical-like nanostructures could be formed from the tessellated triangles and octahedrons, respectively, through hierarchical self-assembly. In addition, after hybridization with carbon nanotubes, the supramolecules exhibit electrochemical reduction activity for CO 2 to CO.

Natural rubber (NR) composites filled with various sepiolite loadings were prepared and optimized by two different mixing methods, namely, melt mixing and latex mixing methods. The properties were evaluated through viscosity, stress relaxation, curing behaviors and tensile properties of rubber composites. The viscosity was influenced by sepiolite content and mixing methods. The greater interaction between rubber and sepiolite was obtained from melt mixing method. This reflected to the greater tensile strength found in this method. Considering the content of sepiolite, similar trend was observed for the curing properties and elongation at break. The greatest tensile strength was observed when the sepiloite content was at 1 phr.

Effect of TPU hard segment content on TPU’s bead foaming behavior

AIP Conference Proceedings 2020年第1期2205卷

A lab-scale bead foaming reactor was used to investigate the foaming behavior of thermoplastic polyurethane (TPU) samples with different hard segment contents of around 39 %, 49 % and 57%. The saturation temperature, pressure, and time differently influenced the formation of hard segment crystals with different close-packed structures and sizes. Consequently, with the increase in hard segment crystallization during the saturation the heterogeneous cell nucleation was improved and the foam expansion was controlled by the stiffness of the TPU/CO2 mixture, solubility of CO2, and final shrinkage of the foamed samples. As the saturation temperature increased, the expansion ratio tended to increase with a tendency to shrink more due to the reduced crystallites content. This is while the cell density decreased due to the reduced hard segment crystallites generated during the saturation. Increase in pressure also improved the CO2 solubility and hence the expansion ratio was increased more significantly. The saturation time also influenced the amount and perfection degree of hard segment crystals. The interrelation between the crystallization behavior of the TPU bead foams and process conditions was reported using differential scanning calorimetry (DSC) and scanning electron microscope (SEM) analysis.

Fiber-reinforced semicrystalline polymer composites are largely employed for their improved strength with respect to the pure polymer matrix. The adhesion between the polymer and the fiber is known to play a key role in determining the overall mechanical behavior. Heterogeneous nucleation on the surface of the solid fiber is an efficient way to improve the adhesion [1] and speeding up the composite production rate. However, fiber induced nucleation studies are still scarce and mainly limited to polyolefins,[2,3] despite the increasing

Induced magnetospheres form around planetary bodies with atmospheres through the interaction of the solar wind with their ionosphere. Induced magnetospheres are highly dependent on the solar wind conditions and have only been studied with single spacecraft missions in the past. This gap in knowledge could be addressed by a multi-spacecraft plasma mission, optimized for studying global spatial and temporal variations in the magnetospheric system around Venus, which hosts the most prominent example of an induced magnetosphere in our solar system. The MVSE mission comprises four satellites, of which three are identical scientific spacecraft, carrying the same suite of instruments probing different regions of the induced magnetosphere and the solar wind simultaneously. The fourth spacecraft is the transfer vehicle which acts as a relay satellite for communications at Venus. In this way, changes in the solar wind conditions and extreme solar events can be observed, and their effects can be quantified as they propagate through the Venusian induced magnetosphere. Additionally, energy transfer in the Venusian induced magnetosphere can be investigated. The scientific payload includes instrumentation to measure the magnetic field, electric field, and ion-electron velocity distributions. This study presents the scientific motivation for the mission as well as requirements and the resulting mission design. Concretely, a mission timeline along with a complete spacecraft design, including mass, power, communication, propulsion and thermal budgets are given. This mission was initially conceived at the Alpbach Summer School 2022 and refined during a week-long study at ESA’s Concurrent Design Facility in Redu, Belgium. © 2023, CC BY-NC-ND.

Two-dimensional van der Waals heterostructures (2D vdWHs) have recently gained widespread attention because of their abundant and exotic properties, which open up many new possibilities for next-generation nanoelectronics. However, practical applications remain challenging due to the lack of high-throughput techniques for fabricating high-quality vdWHs. Here, we demonstrate a general electrochemical strategy to prepare solution-processable high-quality vdWHs, in which electrostatic forces drive the stacking of electrochemically exfoliated individual assemblies with intact structures and clean interfaces into vdWHs with strong interlayer interactions. Thanks to the excellent combination of strong light absorption, interfacial charge transfer, and decent charge transport properties in individual layers, thin-film photodetectors based on graphene/In 2 Se 3 vdWHs exhibit great promise for near-infrared (NIR) photodetection, owing to a high responsivity (267 mA W −1 ), fast rise (72 ms) and decay (426 ms) times under NIR illumination. This approach enables various hybrid systems, including graphene/In 2 Se 3 , graphene/MoS 2 and graphene/MoSe 2 vdWHs, providing a broad avenue for exploring emerging electronic, photonic, and exotic quantum phenomena.
