Summary: The dispersion level of carbon nanotubes and interface design play crucial roles in the mechanical performance of polymer/carbon nanotube nanocomposites. This study focuses on grafting copolymers with different chain lengths onto multiwall carbon nanotubes to improve the properties of the composites. The results show that composites with shorter chain lengths exhibit the best mechanical performance.

Summary: The researchers propose a solution to the metal-semiconductor contact resistance problem, called modulation doping, by placing a doping layer on the opposite side of the metal-semiconductor interface. By using first-principles calculations, they demonstrate that modulation doping can reduce the Schottky barrier height and contact resistance at the metal-semiconductor interface. The feasibility of this approach is demonstrated for single-layer tungsten diselenide and 2D MXene materials, and it can be generalized for other 2D semiconductors.

Summary: This study investigated the key factors influencing the stick-slip behavior of polymer/metal through experiments at varying temperatures. It was found that the friction behavior and interfacial interaction are temperature-dependent. The transition in interfacial interaction from adhesion to plastic deformation with increased temperature is responsible for the reduction in stick-slip intensity.

Summary: The temperature-dependent reactions at the FM/Cr interface were determined using the correlation between electrical contact resistance measurement and microanalysis. The oxidation of Cr by oxygen in FM was identified through a sharp increase in contact resistance, followed by a resistance decrease associated with corrosion. The turning point for corrosion-oxidation was observed at around 390 +/- 1.7 degrees C. The saturation of Cr in FM, combined with complete consumption of oxygen, resulted in a stabilized interface and a specific contact resistance of about 30 mu Omega.cm(2).

Summary: The operating temperature of batteries is crucial and understanding the temperature dependence is important for battery design. While the dendrite issue in lithium-ion batteries is exacerbated at lower temperatures and suppressed at higher temperatures, the opposite temperature dependence is observed in aqueous rechargeable zinc-based batteries. The differences in organic and aqueous electrolytes result in this reversed temperature dependence.

Summary: The study found that acicular grindable thermocouples perform similarly to conventional J-type thermocouples, but exhibit higher temperatures during friction compared to those measured by infrared thermography. Combining acicular and conventional thermocouple techniques allows for more accurate prediction of infrared thermography contact temperatures.

Summary: Gallium-based liquid metal-copper foam (GBLM-CF) thermal interface material is effective in reducing the thermal contact resistance at solid-solid interfaces. The study shows that the interfacial tension of GBLM is inversely proportional to the concentration of HCl, and the presence of CuGa2 promotes the wettability of GBLM. The TCR of GBLM-CF is reduced by 58.28% through the increase of external pressure and improvement of wettability.

Summary: In order to enhance heat dissipation, a strategy was demonstrated to reduce the thermal contact resistance between graphene paper and the mating surface. By decorating graphene paper with polydopamine EGaIn nanocapsules using a dip-coating process, the thermal contact resistance was decreased, resulting in a 26% improvement in cooling efficiency compared to the undecorated case.

Summary: In order to improve the performance of metal bipolar plates, CrAlCN coating with high corrosion resistance and conductivity was deposited on SS316L substrate using CFUMSIP technique, and cost-effective acetylene gas (C2H2) was utilized as a carbon source. XRD and XPS results showed that the proportion of carbides in the coating increased with increasing carbon contents. Electrochemical measurements demonstrated that the C-doped coating significantly enhanced the corrosion resistance of SS316L bipolar plates. The C doping improved the conductivity of the CrAlN coating, and the C-doped sample achieved the lowest ICR value (2.94 m Ωcm2, before corrosion), which was well below the DOE target (≤10 m Ωcm2). The excellent conductivity and hydrophobicity of the C-doped coating increased the power density of a single cell. This study highlights the great application prospects of CrAlCN coatings in the field of bipolar plates.
