Carbon fiber-reinforced plastic (CFRP) has been widely investigated as a reinforcement material to address the corrosion and durability issues of reinforced concrete (RC). To improve the strain of FRP grids, we investigated the effect of single-fiber types, hybrid ratios, and stacking patterns on the strain of the composite materials. Blended fabrics in which different fibers are woven were used to further improve the strain of carbon fibers (CFs). In the blended fabrics, CFs with high tensile strength were mixed with high-strain glass fibers (GFs) or aramid fibers (AFs). Fibers with different mechanical properties were mixed to improve the strain without reducing the tensile strength of the composite materials. The fiber arrangement direction was controlled by CF/GF blended fabric. CFs are arranged in the direction parallel to the tensile load direction with no strength degradation, and GFs are arranged in the direction perpendicular to the increase in strain. Compared to the mechanical properties of the single CF composites, the fabrics obtained via an FRP mixing method proposed in this study showed an increase in the tensile strength by 7% from 568.17 to 608.34 MPa with no strength degradation and an increase in strain by 34% from 0.97% to 1.30%.

In this work, we employ a simple mechanical mixing strategy to directly incorporate VCT MXene with metallic Na as an anode for Na metal batteries, which enables highly reversible and dendrite-free properties during the Na plating/stripping processes. Our findings reveal that the VCT host in the Na metal anode promotes uniform Na deposition, attributed to its abundant -O and -F surface functional groups, and we believe that this work provides a feasible approach to improve the electrochemical performance of sodium metal anodes.

Materials for extreme-condition thermal insulation need to simultaneously withstand complex thermomechanical stresses while retaining their insulating properties at high temperatures. Ceramic aerogels are attractive candidates, but conventional low-entropy ceramics usually suffer from formidable grain growth with severe volume shrinkage and strength degradation, resulting in catastrophic failures. Herein, a high-entropy (LaSmGdY)ZrO (ZLSGY) aerogel is made through an element-phase design, realizing enhanced lattice distortion and sluggish diffusion effects to achieve fine-grain strengthening under extreme conditions.

Nowadays, extensive research has been conducted on electrospun nanofibers for wound dressing applications. Considering the growing concern over bacterial resistance to common antibiotics, investigating the potential of natural essential oils with antibacterial properties could prove to be beneficial in addressing this issue. In response to the challenges posed by impaired wound healing, we have designed a novel electrospun polyvinyl alcohol/chitosan nanofiber embedded with myrtle essential oil and gum Arabic dispersion (PVA/CS/MT-GA).

The mechanical properties of the stent have a direct impact on the therapeutic effect after vascular intervention surgery. The flexibility of bending is an important performance to ensure that the vascular stent can adhere to the blood vessels and plaques, reduce vascular damage, and improve the cure rate. A negative Poisson's ratio structural vascular stent with arrow shaped cell is proposed in the paper, and three shapes of connecting bars, namely U-shaped, S-shaped, and linear, are designed.
