Summary: The study found that using mean profile depth (MPD) to evaluate the performance of High Friction Surface Treatment (HFST) is more accurate and reliable than friction test methods, effectively eliminating errors in surface testing and detecting surface distress. Statistical analysis of MPD measurements can effectively identify the effects of influencing factors.

Summary: For highway design, ensuring sufficient skid resistance between tires and pavement surface is crucial. This study conducted comprehensive experimental testing on different aggregates to assess their friction characteristics. British pendulum and dynamic friction testers were employed to evaluate the proposed aggregates, along with basic and durability tests. The study also developed empirical models for the friction characteristics of high-friction surface treatment (HFST)-application aggregates based on the experimental results.

Summary: This study investigates the feasibility of using high-alumina refractory waste as alternative aggregates in high-friction surface treatment (HFST). It suggests that silicon carbide-mullite brick (SMB) is a suitable replacement aggregate, providing friction comparable to calcined bauxite. The study also explores the skid resistance mechanism of HFST based on the macro and micro textures of the aggregate, providing insights for the preparation of low-cost and low-energy HFST using environmentally friendly aggregates.

Summary: This paper presents a laser surface-texturing technique for manufacturing a surface with tailored high static friction coefficient for large marine engines. By combining laser texturing and surface hardening, the surface properties can be adjusted to achieve the desired friction coefficient. The solution has been successfully tested on driveshafts for ships and is planned for adoption in production.

Summary: HFST is effective in improving friction on curved roadways, but friction drops significantly at the end of its service life, prompting the need for new safety performance measures. Research has shown a strong correlation between HFST aggregate loss and friction value, making it a valuable supplementary measure for monitoring HFST safety performance deterioration.

Summary: The splitting of the liquid film into isolated micro zones is an important function of the hexagonal texture. The orientation and size of the hexagonal texture have noticeable effects on the drainage rate. Residual micro-droplets are entrapped within the contact regions of single hexagonal micro-pillars and gradually shrink as the hexagonal texture downsizes. A novel geometrical shape is proposed to improve the drainage efficiency.

Summary: Osteoarthritis, a common degenerative joint disease, causes serious pain due to the progressive loss and destruction of articular cartilage. Restoring joint lubrication is crucial for its treatment, and various lubricants have been developed to reduce friction and promote cartilage repair. This review discusses the recent progress in natural, bioinspired, and alternative lubricants for osteoarthritis treatment, as well as their structural characterization and lubrication properties.

Summary: Blood vessel anastomosis by suture is a commonly used life-saving technique, but it is time-consuming and labor-intensive. This study proposes practical less-suture strategies using adhesive films for anastomosis, which reduces the number of stitches required and saves operating time. The decreased stitches also help alleviate fibrosis-mediated wall-thickening. This strategy is particularly useful for emergency situations and anastomosis of small-diameter vessels.
