MXenes have been used as substrate materials for single-atom catalysts (SACs) due to their unique two-dimensional (2D) structure, high surface area, and electronic conductivity. Oxygen is the primary terminating group of MXenes; however, all reported Pt SACs till now are fabricated with F-terminated MXenes. According first-principles calculations this work, failure using O-terminated substrates low charge density around C, which weakens catalytic activity Pt. By adjusting structure M2C a...
Abstract. We utilized the global atmospheric reanalysis ERA5 and reconstructed sea surface temperature (SST) data from 1979 through 2020 to examine stability of relationship between SST oscillations in southern Indian Ocean Atlantic Ocean, as described by Subtropical Dipole (SIOD) South (SAOD) indices, respectively. note a significant positive correlation two indices prior year 2000 but practically no afterwards. show that decades 2000, phase SAOD is associated with more convective...
Abstract. The Nanjing University of Information Science and Technology Earth System Model version 3 (NESM v3) has been developed, aiming to provide a numerical modeling platform for cross-disciplinary earth system studies, project future Earth's climate environment changes, as well conduct subseasonal-to-seasonal prediction. While the previous model NESM v1 simulates internal modes variability, it no vegetation dynamics suffers considerable radiative energy imbalance at top atmosphere...
GlobeLand30, the world’s first 30m-resolution global land cover data set, has recently been issued for research on change at a fine resolution. Given accuracy of GlobeLand30 may show significant variation in different parts world and quality continental scale not validated yet, this study aims to evaluate uncertainty over Central Asia. Since it is difficult get long-term historical ground references, most recent epoch (<i>i.e.</i>, GlobeLand30-2010) was assessed....
Centrifugal spray deposition forming technology, which is used in the preparation process of near-net-forming billets, not only reduces macroscopic segregation and refines microstructures billets but also has characteristics a rapid solidification structure. The trajectory, velocity, heat transfer metal droplets granulated by centrifugal force during flight will affect shape, precision microstructure billet. Therefore, it necessary to study dynamics thermal history flight. In this study,...
We investigate seasonal trends in sea ice concentration and the relative contributions of Antarctic Oscillation (AAO), Pacific-South American two modes (PSA1 PSA2), El Niño-Southern (ENSO). The summer range trend is largest, from −83.8% to 59.6% per 29 yr over period 1979 through 2007, while autumn least, −49.7% 39.6% for 2007. In autumn, among four indices largest contribution AAO; winter ENSO PSA1 are better than other indices; during spring a change more 15% associated with PSA1. No...
Abstract. We present a topographic digital elevation model (DEM) for Princess Elizabeth Land (PEL), East Antarctica – the last remaining region in to be surveyed by airborne radio-echo sounding (RES) techniques. The DEM covers an area of ~900,000 km2 and was established from new RES data collected ICECAP-2 consortium, led Polar Research Institute China, four campaigns since 2015. Previously, (along with Recovery basin elsewhere Antarctica) characterised inversion using low resolution...
The acceleration capability of a centrifugal jet rotor plays crucial role in achieving high injection velocity powder particles the impact moulding process. In this regard, focus article is on optimization runner shape. To end, lengths first and second sections (L1 L2), angles between third (α1 α2) are considered as parameters. Simulations were conducted using multiple discrete elements to explore influence input parameters response value, regression model was established particle rate....
Abstract Constraining the timing and extent of Quaternary glaciations in Tibetan Plateau (TP) is significant for reconstruction paleoclimatic environment understanding interrelationships among climate, tectonics, glacial systems. We investigated late history Qinggulong Juequ valleys Taniantaweng Mountains, southeastern TP, using cosmogenic 10 Be surface exposure dating. Four major events were identified based on 26 ages. The ages oldest glaciation correspond to Marine Oxygen Isotope Stage...
Short-term precipitation commonly occurs in south part of China, which brings intensive local region for very short time. Massive water would cause the flood inside city when amount beyond capacity drainage system. Thousands people’s life could be influenced by those short-term disasters and higher managements are required to facing these challenges. How predict occurrence heavy accurately is one worthwhile scientific questions meteorology. According recent studies, accuracy prediction based...
In this study, the impact of flow channel structures on acceleration metal particles in a vacuum environment is explored, with aim enhancinge quality centrifugal molding powders. To assess phenomenon, three evaluation indices are introduced: average speed thrown Vp , Vall and particle velocity distribution Vf (t). Additionally, effects six distinct runner analyzed research. The findings indicate that arc-shaped structure not only ensures more consistent process but also results higher...
The Indo-Pacific Warm Pool (IPWP) has been warming due largely to increasing greenhouse gas emissions, but its impact on Arctic sea ice remains unclear. Our study finds a significant negative correlation between the IPWP index and concentration in northeastern Canada during boreal autumn (October-December). results suggest that statistically accounts for 45% of loss observed this region. We introduce "Arctic capacitor effect IPWP", novel concept expounds upon distant connection emissions...
Human activities and scientific expeditions in Antarctica rely significantly on the logistics ice snow covered continent, roads runways play a pivotal role inland intercontinental transportations respectively. In study, we focus uniaxial compression strengths of compacted Antarctic near Zhongshan Station, which is key mechanical property to runway design safety. Dense was broken into pieces sieved before metal molds densities 0.5, 0.6 or 0.7 g/cm3, then subjected isothermal sintering at -10℃...
Abstract Ridge B is one of the least studied areas in Antarctica but has been considered to be a potential location for oldest ice on Earth. Among important parameters calculating where very old may exist, geothermal heat flux (GHF) critical poorly understood. Here, GHF determined by quantifying transitions between dry and wet basal conditions using radioglaciological method applied airborne radio-echo sounding data. then constrained thermodynamic model matched transitions. The results show...
