Summary: This study prepared cement mortars with different contents and sizes of multiwalled carbon nanotubes (MWCNTs) using surfactants and ultrasonic dispersion. The effects of MWCNT content, diameter, and length on the electrical conductivity and self-inductive piezoresistive rate of the cement mortar were investigated. The results showed that the conductive percolation threshold occurred at approximately 0.1 wt% MWCNT content. The highest electrical conductivity was observed for MWCNTs with diameters of 10-20 nm at a content of 0.1 wt%, reaching 112% and 128.3% compared to MWCNTs with diameters of 20-40 nm and 40-60 nm, respectively. The fractional change in resistivity was most significant at a content of 0.75 wt% MWCNTs, reaching 14.27%. Adding small-diameter MWCNTs can maximize the sensitivity of electrical resistance to compressive stress in cement mortar.

Summary: Organic conductive polymer/carbon nanoparticle thermoelectric composites have attracted attention due to their promising structural and electrical characteristics. By combining chemical oxidative polymerization, acid-treatment of SWCNT, and vacuum filtration, flexible films of PEDOT-Tos/a-SWCNT composites with enhanced TE performance were fabricated. The layered morphology and strong pi-pi interactions between polymer chains and SWCNT contribute to a highly conductive network, while the acid-treatment acts as p-type doping for SWCNT to achieve high electrical conductivity. This study demonstrates the potential for polymer-based composites in TE applications.

Summary: This study presents a method to enhance the electrical performance of CNT films by controlling the wettability of LMWCNT films and the electrical conductivity of the Cu plating solution. Thermal deoxygenation was used to modify the CNT surface, providing high conductivity and hydrophilicity for uniform Cu electrodeposition in an aqueous electrolyte. The results show that Cu nucleates from inside the CNT film and grows on the surface, forming a densely packed CNT-Cu composite.

Summary: In this study, an electrochemical sensor for the determination of BHA was developed by electropolymerization of OC over MWCNTs. The POC/MWCNTs electrode showed BHA oxidation occurring at 0.27 V, with a linear detection range from 0.33 mu M to 110 mu M and a detection limit of 0.11 mu M. Amperometric determination of BHA using chronoamperometric techniques confirmed the linear relationship. The real-time analysis of sensors was validated by analyzing packed potato chips samples.

Summary: In this paper, a new form-finding method based on spatial elastica model (FMSE) is proposed for elastic gridshells. The method integrates the deformations of elastic rods into the overall deformation of the gridshell, and solves a set of transcendental equations using the quasi-Newton method to ensure the deformation satisfies the given boundary conditions. The method is validated through experiments and expected to have potential applications in the investigations of elastic gridshells.

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.
