Summary: The study focuses on the in-situ assembly of carbon nanotubes (CNTs) using macroscopic dielectrophoresis, overcoming the limitation of small size in traditional manipulation methods. Through optimizing voltage and frequency, ordered CNTs chains can be obtained under the action of alternating current dielectrophoresis, which can restore immediately upon powering up after being damaged. Different conductive patterns on non-woven fabric can be achieved by controlling the position of the electrodes in a wet environment.

Summary: In this study, a novel biosorbent derived from Bauhinia variegata pods was used for defluoridation of fluoride contaminated water. Physically Treated Bauhinia and Chemically Treated Bauhinia were compared, with the latter showing higher adsorption capacity. The adsorption process was described by the Pseudo first-order model and thermodynamic parameters indicated favorable conditions. Column studies using models like Yoon-Nelson showed promising results, with a maximum adsorption capacity of 1.176 mg/g achieved.

Summary: In this study, novel flexible temperature sensors based on carbon nanotube forest composites were developed, demonstrating simple fabrication processes, biocompatibility, high performance, and a stable sensing scheme. These sensors exhibit sensitivities of around 0.1 ohms/degrees C or higher and have a stable Young's modulus of around 0.1 MPa for temperatures below 100 degrees C, paving the way for a new generation of flexible, wearable, and biocompatible temperature sensors.

Summary: By introducing nonionic surfactant into the typically employed mixture of anionic surfactants, the aqueous two-phase extraction (ATPE) method can be enhanced for the straightforward isolation of (6,4) single-walled carbon nanotubes (SWCNTs) in one step. Thorough analysis of the parameter space by experiments and modeling reveals the underlying interactions between SWCNTs, surfactants, and phase-forming agents, which drive the partitioning. A separation mechanism is proposed based on the new insight gained.

Summary: In this study, we report on the development of an implantable artificial muscle made by soaking-polymerization of polyaniline (PANI) inside a carbon nanotube (CNT) yarn. The yarn muscle generates a large contractile stroke and high isometric stress in aqueous biocompatible solutions, surpassing the performance of previously reported artificial yarn muscles. The CNT/PANI yarn muscles also exhibit excellent actuating performance in other biocompatible solutions, making them suitable for implantable bionic applications.

Summary: The study compared the dispersion of carbon nanotubes using different surfactants in binary systems. It found a synergistic effect between SDBS and TX-100 in enhancing the dispersion of CNTs, with SDBS likely acting as a trigger due to its small molecular size. However, the synergistic effect disappeared when the concentration of TX-100 exceeded its critical micelle concentration.

Summary: The addition of carbon nanotubes (CNTs) and carbon fibers (CFs) can enhance the dynamic compressive strength of concrete. The combination of CNTs and CFs has a better effect on improving the strain-rate effect of the concrete. The addition of CNTs improves the porosity and enhances the dynamic compressive strength, while the addition of CFs increases the porosity but still enhances the strength.

Summary: With an increasing focus on energy harvesting, studies on practical application and performance of energy harvesters are becoming more prevalent. Researchers are exploring the use of continuous energy sources, such as wind, river flow, and sea waves, for energy-harvesting devices. A new technology based on coiled carbon nanotube (CNT) yarns has emerged, which generates energy through mechanical stretch and release. This technology has been demonstrated in a variety of fluid flow environments and tested in river and ocean settings.

Summary: A facile and robust strategy using cellulose in NaOH/thiourea aqueous solution is reported for the rapid and scalable preparation of homogeneous and stable CNT dispersion. The CNT dispersion is demonstrated to be suitable for aqueous self-assembly of various functional materials, ranging from zero-dimensional (0D) microsphere to three-dimensional (3D) monolith through various molding techniques. The dispersion can also be used as ink for CNT-based paper and textile, showing potential for flexible and wearable devices.
