Summary: This study presents a soft robotic strategy that couples actuation and strain sensing into a single homogeneous material, which exhibits photo/thermal-responsiveness and piezoresistive-responsiveness, enabling remotely-triggered actuation and local strain-sensing. The material demonstrated ultra-high stretchability and large volume shrinkage, with a drastic change in conductivity upon locomotion. The multifunctional sensory actuatable materials may lead to the next generation of soft robots with higher levels of autonomy and complexity.

Summary: By controlling the electron scattering and tunneling effects, a temperature-independent thin-film strain gauge (TFSG) is successfully fabricated. The ceramic films made of TiB2/SiCN composites show constant resistance values over a wide temperature range, with a deviation of less than 0.05% and a low temperature coefficient of resistance (TCR) as low as 1.6 ppm/°C. Additionally, the TiB2/SiCN films exhibit stable piezoresistive responses with a gauge factor of 4.28.

Summary: This article introduces a technique for the direct growth of graphene on GaN LED epitaxy layers. The technique synthesizes high-quality graphene at low temperature and time, and enables lithography-free patterning of graphene. In-situ Ohmic contact is achieved between graphene and p-GaN by removing the catalyst using a penetration etching method. Graphene exhibits excellent performance and is more scalable, controllable, and compatible with the semiconductor industry than traditionally transferred graphene.

Summary: In this study, a self-powered flow velocity sensor based on hybrid piezo-triboelectric nanogenerator (P-TENG) is proposed for monitoring the flow velocity of an urban ventilation system. The kinetic energy of the moving air is converted into electricity by a polyvinylidene difluoride (PVDF) fixed on the galloping beam, and the flow velocity is detected by a triboelectric nanogenerator (TENG). The experiments demonstrate the accuracy, reliability and applicability of the proposed nanogenerator in detecting flow velocity.

Summary: 2D MXene materials offer the opportunity to manufacture ceramic composites with special structures and functions. By carefully designing and implementing strategies to maintain a complete layered structure and control the exfoliation of MXene sheets, as well as ensuring homogeneous distribution, we can achieve improved mechanical properties and self-monitoring capabilities in the composite materials. The conductivity related to the spatial distribution of MXene sheets enables the composite to potentially be used for smart structural and functional applications.

Summary: The contact resistivity plays a significant role in the performance of solar module interconnects. However, accurately measuring the contact resistivity for interconnects based on electrically conductive adhesive (ECA) is challenging. This study demonstrates that transmission line method (TLM) test structures based on ECA exhibit non-negligible inhomogeneities, leading to inaccuracies in determining the contact resistivity. The analysis of four commercially available ECAs used in solar modules reveals that even without macroscale inhomogeneities, microscopic structural effects affect the sheet and contact resistance, particularly due to variations in filler distribution.

Summary: The study found that with a decrease in Ag content in TiN-Ag composite coatings, hardness increased while electrical conductivity decreased. The coating with 10% Ag content showed the best friction-reducing and anti-wear properties, attributed to the moderate content of Ag embedded in the TiN crystal gap enhancing grain bonding force to improve anti-wear and self-lubricating ability. Graphene can be adsorbed on the coating as a solid lubricant.

Summary: Biopolymers and alkali-activated materials are effective adsorbents for heavy metal removal from aqueous solutions. This study prepared hybrid adsorbents from both materials and investigated the effect of chitosan dosage on the removal efficiency of Pb(II) and Zn(II). The adsorbents showed high removal efficiencies for both metals, with Zn(II) being more effectively adsorbed. The addition of chitosan had little impact on the overall efficiency, except for a decrease with 0.05% chitosan. The choice of alkaline activating solution also influenced the adsorption performance.

Summary: The in-plane mechanical behavior of stacks formed by titanium carbide MXenes was investigated in microscale uniaxial tensile experiments. The Young's modulus of MXene stacks remained almost constant, while the tensile strength decreased with an increase in the number of monolayers. The observed dependence of the tensile strength on the number of stacked MXene monolayers was attributed to defects in different layers within the multilayer MXenes.
