Summary: With the development of electronic technologies, the demand for efficient heat dissipation in electronic devices has led to a focus on carbon-based thermal interface materials, particularly 3D-Gr, which offer both high thermal conductivity and mechanical properties. Different techniques for measuring thermal properties of TIMs need to be carefully selected based on their principles for accurate results.

Summary: A solvent-free MWCNTs @Fe3O4 nanofluid was used to modify the water-based epoxy sizing agent for CFRPs. The addition of 2% MFNF significantly improved the mechanical properties of CFRPs, with ILSS and bending strength increased by 21.69% and 39.51%, respectively. Moreover, the Thermal conductivity was improved by 112.23% due to the excellent TC possessed by MWCNTs and the orientation of MFNF in thermal conductivity, which facilitates phonon propagation at the interface.

Summary: In this study, multi-walled carbon nanotubes (MWCNTs) were uniformly dispersed in aluminium nitride (AlN) powders, and the MWCNTs-doped AlN ceramics were sintered by spark plasma sintering. The effects of MWCNTs content on the microstructure and mechanical properties of the ceramics were investigated, and it was found that a doping amount of 2.5 wt% resulted in the highest relative density and hardness.

Summary: A novel multiscale semi-analytical model is proposed to study the thermal conductive behaviors of carbon nanotube-reinforced composites, demonstrating significant enhancement of transverse thermal conductivity in CFRCs and minimal impact on longitudinal thermal conductivity due to CNT coating. The model is validated against available simulations and finite element method, and localized heat-flux/temperature distributions are recovered to predict crack initiations within microstructures.

Summary: The thermal lensing spectrometry (TLS) method was optimized and applied for the quantification of trace permanganate in water, with lower detection and quantification limits achieved. Experimental results showed that the concentration of permanganate measured by TLS is more accurate compared to conventional absorption spectrometry, and close to the detection limit achieved by indirect spectrometric methods.

Summary: This work presents the calculated values of collision integrals for argon/carbon plasmas. The results are obtained using different potentials and compared with literature data. The calculated values are then used to estimate the viscosity of pure argon and argon/carbon mixtures. The study shows a satisfactory agreement with previous studies and emphasizes the importance of the charge exchange process in the accuracy of the collision integrals. The ILJ approach is recommended when experimental or theoretical data are unavailable.
