The design and synthesis of highly active oxygen reduction reaction (ORR) catalysts with strong durability at low cost is extremely desirable but still remains a significant challenge. Here we develop an efficient strategy that utilizes organopalladium(I) complexes containing palladium-palladium bonds as precursors for the strongly coupled Pd tetrahedron-tungsten oxide nanosheet hybrids (Pd/W18O49) to improve electrocatalytic activity stability nanocrystals. hybrid materials are synthesized...
Ag-graphene composite nanosheets (AGCN) with adjustable size and well-controlled densities of Ag nanoparticles (Ag NPs) using Poly(N-vinyl-2-pyrrolidone) (PVP) as a reductant stabilizer are reported. The obtained AGCN substrate is extremely suitable for surface-enhanced Raman spectroscopy (SERS).
Abstract Humans have grazed on the Qinghai–Tibetan Plateau ( QTP ) for many thousands of years. In recent decades, intensity grazing has increased and several new management strategies been put into place to address resulting changes in rangeland condition. Effective activities this region requires understanding impact livestock across diverse array alpine grassland ecosystems present , but studies identified a number critical uncertainties ecological science that underlies these principles....
Abstract The elevation gradient has long been known to be vital in shaping the structure and function of terrestrial ecosystems, but little is about elevation-dependent pattern net CO 2 uptake, denoted by ecosystem productivity (NEP). Here, analyzing data from 203 eddy covariance sites across China, we report a negative linear NEP, collectively shaped varying hydrothermal factors, nutrient supply, types. Furthermore, NEP shows higher temperature sensitivity high-elevation environments...
Abstract High-entropy alloy nanoparticles (HEA-NPs) exhibit favorable properties in catalytic processes, as their multi-metallic sites ensure both high intrinsic activity and atomic efficiency. However, controlled synthesis of uniform ensembles at the level remains challenging. This study successfully loads HEA-NPs onto a nitrogen-doped carbon carrier (HEAs) pioneers application peroxymonosulfate (PMS) activation to drive Fenton-like oxidation. The HEAs-PMS system achieves ultrafast...
Abstract In recent decades, alpine grasslands have been seriously degraded on the Tibetan Plateau and grazing exclusion by fencing has widely adopted to restore since 2004. To elucidate how carbon (C), nitrogen (N), phosphorus (P) storage responds this management strategy, three types of grassland in nine counties Tibet were selected investigate C, N, P environment comparing free ( FG ) GE treatments, which had run for 6–8 years. The results revealed that there no significant differences...
Altered gut microbiota has been identified during psychological stress, which causes severe health issues worldwide. The integrity of the intestinal barrier and blood–brain regulates process bacterial translocation can supply nervous system with real-time information about environment. However, association stress remains to be fully interpreted. In this study, we established a model using an improved communication box compared expression tight junction proteins in multiple regions (duodenum,...
Abstract Aim Climate change is expected to have important effects on plant phenology and carbon storage, with further shifts predicted in the future. Therefore, we proposed community accumulation rate (CAR) from start of growing season (SOS) peak (POS) fill gap that dynamic interactions between research. Location Tibetan Plateau. Major taxa Alpine grassland plants. Time period 2015. Methods We conducted a transect survey across grasslands measure aboveground net primary production...
Effective management of large basins necessitates pinpointing the spatial and temporal drivers primary index exceedances urban risk factors, offering crucial insights for basin administrators. Yet, comprehensive examinations multiple pollutants within Yangtze River Basin remain scarce. Here we introduce a pollution inventory clusters surrounding Basin, analyzing water quality data from 102 cities during 2018–2019. We assessed exceedance rates six pivotal indicators: dissolved oxygen (DO),...
No single hypothesis or theory has been widely accepted for explaining the functional mechanism of global alpine/arctic treeline formation. The present study tested whether alpine is determined by (1) needle nitrogen content associated with photosynthesis (carbon gain); (2) a sufficient source-sink ratio carbon; (3) C-N ratio. Nitrogen does not limit growth and development trees studied at Himalayan treelines. Levels non-structural carbohydrates (NSC) in were species-specific site-dependent;...
Abstract Although rare earth element (REE) has been widely applied for provenance study and paleoenvironmental reconstruction, its mobility fractionation during surface processes from weathering to sediment deposition remain more clarification. We investigated the REE fractionations chemical river transport based on systematic observations a granodiorite‐weathering profile Mulanxi River sediments in southeast China. Two phases (leachates residues) were separated by 1 N HCl leaching leachates...
Understanding the impact of grazing intensity on grassland production and soil fertility is fundamental importance for conservation management. We thus compared three types alpine steppe management by studying vegetation traits properties in response to levels pressure: permanent (M1), seasonal (M2), exclusion (M3) Xainza County, Tibetan Plateau. The results showed that community biomass allocation did not support isometric hypothesis under different types. Plants M1 had less aboveground but...
Abstract Averaged over 4000 m in elevation, Tibetan Plateau (TP) functions as an important ecological security barrier China. Alpine ecosystems present a trend of overall improvement under the influence climate change and human activities, yet there are localized deteriorations. To improve function TP, large‐scale restoration projects (ERPs) have been carried out past 30 years, which could be classified into three stages, that is, Exploration (1989–2003), Rapid Growth (2004–2014),...
Soil carbon dioxide (CO2) emission is one of the largest fluxes in global cycle. Therefore small changes size this flux can have a large effect on atmospheric CO2 concentrations and potentially constitute powerful positive feedback to climate system. alpine steppe ecosystem Northern Tibet their responses short-term experimental warming were investigated during growing season 2011. The results showed that total soil entire 55.82 104.31 g C m-2 for control plots, respectively. Thus, increased...
