Summary: In this study, high-performance n-type organic-inorganic flexible thermoelectric composites were successfully fabricated using semiconducting graphdiyne (GDY) instead of carbon nanotubes or graphene. The composites showed improved electrical conductivity and achieved a maximum ZT value of 0.2 at 300 K, making them among the highest reported in this field. Additionally, a prototype thermoelectric module consisting of both n-type and p-type legs demonstrated the highest normalized maximum power density compared to other organic material-based flexible thermoelectric modules.

Summary: This paper presents a novel analytical model for accurately calculating the anisotropic thermal conductivity of polymer composites containing aligned one-dimensional nanofillers. The model considers the boundary resistance and introduces a parameter f related to the distances between the nanofillers, effectively capturing their impact on the thermal conductivity. Finite element method simulations validate the model, and comparisons with other theoretical models are made. The proposed model provides a simple yet effective computational approach for predicting and understanding the thermal conductivity of composites with aligned 1D nanofillers.

Summary: In this study, conductive polymer-based materials were successfully obtained by incorporating different amounts of multiwalled carbon nanotubes (MWCNTs) into poly(lactide)(PLA) using electrospinning technique. The presence of MWCNTs in the PLA matrix had a significant influence on the crystallization behavior of PLA nanofibers, while not affecting the conductivity. Additionally, the addition of MWCNTs improved the mechanical properties of composite fibers, leading to increased elasticity and tensile strengths of nanofibers.

Summary: The effects of Lc on the depth of the operative interphase, operative filler concentration, and mechanical percolation start are studied. An equation is proposed to determine the strength of HNT composites with an imperfect interphase and an HNT network. The relationships between B and Lc, HNT size, and percolation start are analyzed. The lowest Lc, lowest percolation start point, slimmest and longest HNTs, and highest interfacial shear strength yielded the highest B values and the toughest samples.

Summary: This study investigates 15 hybrid filler composites containing aluminum oxide, graphite, expanded graphite, carbon nanotubes, or a combination of these fillers, using extrusion-compression processing. The experimental density of the specimens is lower than the theoretical density, especially for composites with high filler contents, due to the presence of air inclusions. The addition of fillers increases both the melt viscosity and the thermal conductivity.

Summary: Micro particles are produced by various cells due to different stimuli in the circulatory system. Shear stress can result in damage to red blood cells and lead to the production of microparticles. High shear stress and longer exposure time can increase the concentration of red blood cell microparticles, which may indicate sub-hemolytic damage to red blood cells.

Summary: The configuration of proteins is crucial for their biochemical behavior, and mechanical stresses can have a significant impact on them, leading to the development of diseases. Extensional stresses, often overlooked, can affect the structure of von Willebrand factor (vWF) protein at much lower stress levels than shear stresses. This study examined the statistical distribution of extensional stress on models of the vWF molecule in turbulent flow and found that the distribution of stresses is important for the design of blood flow devices.

Summary: The study showed that when only surfactants were present, compression led to expulsion of surfactant molecules to the water phase. Compression of an interface laden with Janus particles resulted in interface buckling, while the total interfacial area remained constant. The presence of Janus particles caused buckling even when surfactants were present, leading to higher levels of interface deformation.

Summary: The effects of surface-active nanoparticles and surfactants on the behavior of oil-water interfaces in shear flow were investigated. It was found that the addition of surfactants reduced the slip between water and oil droplets, leading to greater displacement of the droplets. Surfactant molecules tended to concentrate towards the rear side of the droplets. The presence of nanoparticles slowed down droplet migration. However, when both surfactants and nanoparticles were present, the migration speed of the droplets increased compared to bare oil.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
