Abstract

The temperature at which supercooled liquids turn into solid-like glasses ($T_g$) can change at the free surface, affecting the properties of nanostructured glasses and their applications. However, inadequate experimental resolution to determine the $T_g$ gradient and a longstanding debate over the role of nonequilibrium effects have hindered fundamental understanding of this phenomenon. Using spatially resolved $T_g$ measurements and molecular dynamics simulations, we reveal a crossover from equilibrium behavior to a new regime of near-surface nonequilibrium glass physics on cooling. This crossover causes the form of the nonequilibrium $T_g$ gradient to change, highlighting the need to include these physics for rational understanding of the properties of realistic nanostructured glass-forming materials. They also potentially recast the interpretation of decades of experimental data on nanoconfined glasses., Comment: This PDF file includes two documents: The first is the main manuscript, which consists of 13 pages and 4 figures. The second document is the supplementary materials, which contains 25 pages, 8 figures, and 3 tables

Abstract

[Objective] To investigate the changes of soil respiration in desert ecosystems and its relationship with environmental factors during the spring freeze-thaw period in arid and semi-arid regions, and to provide data support for the carbon budget of sandy land ecosystems in arid and semi-arid regions. [Methods] Soil respiration rates of salix plantations that were untouched and unlevelled stubble (ww), untouched and levelled stubble (wp), untouched and unlevelled stubble (zw), and levelled and levelled stubble (zp) were measured in the snow-free treatment by using the Li-6800 soil-carbon-water flux measurement chamber in the Salix Forest Germplasm Resource Bank of the Dalate Banner, Ordos, Inner Mongolia, and the atmospheric temperature, soil temperature and humidity were measured simultaneously. [Results] The results showed that the daily change of soil respiration during the freeze-thaw alternation period showed a unimodal trend, with the peak occurring between 10:00 am and 12:00 pm. Snowfall accelerated soil respiration rate and enhanced the temperature sensitivity of soil respiration (Q10) during the spring freeze-thaw period, but it did not change the daily change pattern of soil respiration. After stubble levelling of the salix plantation, soil respiration rate slowed down but Q10 increased; land preparation measure reduced the daily flux of soil respiration in general, and it also reduced the Q10 value. Soil respiration was significantly correlated with soil temperature under each treatment, and the single factor model could explain 51%~68% of the variation in soil respiration (p
