Global streamflow, crucial for ecology, agriculture, and human activities, can be influenced by elevated atmospheric CO (eCO) though direct regulation of vegetation physiology and structure, which can either decrease or increase streamflow. Despite a 21.8% rise in CO over 40 years, its impact on streamflow is not obvious and remains highly debated.

Vegetation change in the Tibetan Plateau (TP) is a crucial indicator of climate change in alpine regions. Previous studies have reported an overall greening trend in the vegetation structure across the TP, especially in its northeastern part, in response to a warming climate. However, variations in the vegetation function and the possible drivers remain poorly understood.

Root zone soil moisture (RZSM) is particularly useful for understanding hydrological processes, plant-land-atmosphere exchanges, and agriculture- and climate-related research. This study aims to estimate RZSM across China by using a one-parameter (T) exponential filter method (EF method) together with a random forest (RF) regionalization approach and by using a large dataset containing in situ observations collected at 2121 sites across China. First, at each site, T is optimized at each of four soil layers (10-20 cm, 20-30 cm, 30-40 cm and 40-50 cm) by using 0-10-cm soil layer observations and the corresponding calibration layers.

Efficient separation of photogenerated electron-hole pairs is a crucial factor for high-performance photocatalysts. Effective electron-hole separation and migration could be achieved by heterojunctions with suitable band structures. Herein, a porous SrTiO /SrSO heterojunction is prepared by a sol-gel method at room temperature followed by an annealing process.

Single crystalline strontium titanate (SrTiO) submicron cubes have been synthesized based on a molten salt method. The submicron cubes showed superior photocatalytic activity towards both water splitting and carbon dioxide reduction, in which methane (CH) and hydrogen (H) were simultaneously produced. The average production rate of methane up to 8 h is 4.
