climate warming profoundly affects plant biodiversity, community productivity, and soil properties in alpine and subalpine grassland ecosystems. However, these effects are poorly understood across elevational gradients in subalpine meadow ecosystems. To reveal the elevational patterns of warming effects on plant biodiversity, community structure, productivity, and soil properties, we conducted a warming experiment using open-top chambers from August 2019 to August 2022 at high(2764 m a. s. l.), medium(2631 m a. s. l.), and low(2544 m a. s. l.) elevational gradients on a subalpine meadow slope of Mount Wutai, Northern china. Our results showed that three years of warming significantly increased topsoil temperature but significantly decreased topsoil moisture at all elevations(Pcentage of increasing temperature and decreasing moisture both gradually raised with elevation lifting. Warming-induced decreasing proportions of soil organic carbon(SOc, by 19.24%), and total nitrogen(TN, by 24.56%) were the greatest at high elevational gradients. Experimental warming did not affect topsoil c: N, p H, NO_(3)^(-)-N, or NH_(4)^(+)-N at the three elevational gradients. Warming significantly increased species richness(Pcantly decreased belowground biomass(Pcm at three elevational gradients. Warming caused significant increases in the aboveground biomass in the three elevational plots. Warming significantly increased the aboveground biomass of graminoids in medium(by 92.47%) and low(by 98.25%) elevational gradients, that of sedges in high(by 72.44%) and medium(by 57.16%) elevational plots, and that of forbs in high(by 75.88%), medium(by 34.38%), and low(by 74.95%) elevational plots. Species richness had significant linear correlations with SOc, TN, and c: N(Pcant nonlinear responses to soil temperature and soil moisture in the warmed treatm

Thermal Barrier coatings (TBcs) technology is key to improving the service temperature and the productivity of aircraft engines. The performance and failure life of TBcs are strongly influenced by surface integrity and microstructure. Therefore, recognizing failure mechanisms and developing effective surface treatment processes are crucial for further improving the reliability and durability of TBcs. This paper explains the primary reasons for TBc failure, emphasizing on how integrity of surface and interface influences interfacial oxidation, high-temperature erosion, and calcium-Magnesium-Alumina-Silicate (cMAS) corrosion. Furthermore, this paper completely and rigorously evaluates the research status of TBcs surface treatment processes, including the characteristics and effects of various processes, and describes the requirements and goals of pretreatment and post-treatment. In addition, a potential direction for the development and application of TBcs surface treatment is suggested.
