Purpose: To examine whether the ion exchange strengthening can be achieved for several new ceramics such as glass ceramics or castable ceramics.
Methods: The ceramics selected for this study were three porcelains and three castable ceramics. 60 bend bars of the respective ceramics (1 x 5 x 10 mm) were fabricated according to the respective manufacturer's directions. Finally, the respective specimens were polished up to 0.1 microm and then divided into two groups: one was coated with an ion-exchange paste and the other was not treated as the control. Then, for the respective ceramics the hardness, flexural strength and fracture toughness were investigated and compared to the control.
Results: Although the ion-exchange treatment significantly (P < 0.05, Scheffé's test) increased flexural strength and fracture toughness for the porcelain based ceramics, it did not increase these properties for the castable ceramics. The chemical treatment did not affect hardness for any of the specimens.

Solar energy-driven steam generation is a renewable, energy-efficient technology that can alleviate the global clean water shortage through seawater desalination. However, the contradiction between resistance to salinity accretion and maintaining high water evaporation properties remains a challenging bottleneck. Herein, we have developed a biomimetic multiscale-ordered hydrogel-based solar water evaporator for efficient seawater desalination.

Fiber-based artificial muscles are soft actuators used to mimic the movement of human muscles. However, using high modulus oxide ceramics to fabricate artificial muscles with high energy and power is a challenge as they are prone to brittle fracture during torsion. Here, a ceramic metallization strategy is reported that solves the problem of low torsion and low ductility of alumina (AlO) ceramics by chemical plating a thin copper layer on alumina filaments.

Total hip arthroplasty (THA) is a highly effective surgical intervention for end-stage hip joint disorders. While common complications such as infection, dislocation, and prosthetic loosening are well-documented, rarer complications remain underreported. One such complication is foreign body interposition on the bearing surface, which can compromise joint mechanics and adversely affect outcomes.

Cysteine S-carboxyethylation, a novel post-translational modification (PTM), plays a critical role in the pathogenesis of autoimmune diseases, particularly ankylosing spondylitis. Accurate identification of S-carboxyethylation modification sites is essential for elucidating their functional mechanisms. Unfortunately, there are currently no computational tools that can accurately predict these sites, posing a significant challenge to this area of research.
