This study provided a facile and green method to prepare stable colloid silver nanoparticles in aqueous solution by utilizing the amine-terminated hyperbranched poly(amidoamine) (HPAMAM-NH2) as both stabilizer reductant. The formation of was verified FTIR, UV−vis, TEM, EDS, XRD measurements. Monodispersed with small particle sizes were obtained, average size could be effectively controlled from ca. 15 4 nm simply adjusting molar ratio N/Ag feed. antibacterial activity HPAMAM-NH2/Ag...
The enrichment of heavy rare earth elements (HREE) in the granitic host-rocks is crucial for generating ion-adsorption HREE deposits South China. Shitouping pluton, located southern part Jiangxi Province, China, develops large-scale its weathering profile identified by recent geological surveys. These granites can be divided into medium to coarse-grained biotite monzogranite (MGBG), syenogranite (MGSG) and fine-grained alkali feldspar granite (FGAG) based on field observations mineral...
Abstract Mineralogical distribution, textures, electron probe microanalysis of visible gold, laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) trace element analysis pyrite, and LA-multicollector (MC-)ICP-MS sulfur isotope sulfide minerals are examined in an ore zone extending obliquely to –4 km depth the Sanshandao gold deposit Jiaodong, China. We relate these results temporal spatial ore-forming processes further elucidate controls on deposition Au fineness variation....
Abstract Emergence refers to the existence or formation of collective behaviors in complex systems. Here, we develop a theoretical framework based on eigen microstate theory analyze emerging phenomena and dynamic evolution system. In this framework, statistical ensemble composed M microstates system with N agents is defined by normalized × matrix A , whose columns represent order row consist time. The can be decomposed as <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
We employ the eigen microstates approach to explore self-organized criticality (SOC) in two celebrated sandpile models, namely BTW model and Manna model. In both phase transitions from absorbing state critical can be understood by emergence of dominant with significantly increased weights. Spatial avalanches uniformly characterized a linear system size rescaling. The first temporal reveal scaling relations models. Furthermore, finite-size analysis microstates, we numerically estimate...
The Xiekeng pluton, located in Huichang County, Jiangxi Province, is primarily composed of two-mica monzogranite. rock features high contents SiO 2 (71.3–77.73 wt%), K O (4.42–5.62 O/Na (1.36–1.87), and with an A/CNK value 1.11–1.27, a differentiation index (DI) 90.28–94.47, zircon saturation temperatures 780°C–806°C, K/Rb, Nb/Ta, Zr/Hf ratios 8.40–11.04, 2.38–9.24, 25.42–35.37, respectively. It also contains peraluminous minerals such as muscovite, classifying it highly fractionated S-type...
Variations in stratospheric atmospheric circulation significantly impact tropospheric weather and climate. Understanding these variations not only aids better prediction of climate but also provides guidance for the development flight trajectories aircraft. Our understanding stratosphere has made remarkable progress over past 100 years. However, we still lack a comprehensive perspective on large-scale patterns circulation, as is typical complex system. To address this gap, employed eigen...
Earthquake activity poses significant risks to both human survival and economic development. However, earthquake forecasting remains a challenge due the complex, poorly understood interactions that drive seismic events. In this study, we construct an percolation model examine relationships between earthquakes underlying patterns processes in Southern California. Our results demonstrate can capture spatiotemporal magnitude characteristics of activity. Through clustering analysis, identify two...
SUMMARY The scientific process of earthquake forecasting involves estimating the probability and intensity earthquakes in a specific area within certain timeframe, based on seismic activity features observational data. Among various methodologies, epidemic-type aftershock sequence (ETAS) models, rooted empirical laws, stand as widely used tools for forecasting. In this study, we introduce CL-ETAS model, novel approach that integrates convolutional long short-term memory (ConvLSTM), deep...
A novel hyperbranched polymer gelator has been synthesized, which can self-assemble into the thermoreversible physical gel in DMF, DMAC, pyridine, DMSO or NMP with driving force of hydrogen bonds among amide and amine groups highly branched macromolecules.
Over the past decades much effort has been devoted towards understanding and forecasting natural hazards. However, earthquake skill is still very limited remains a great scientific challenge. The predictability partly due to erratic nature of earthquakes lack underlying mechanisms earthquakes. To improve our potential forecasting, here we study spatial temporal long-term memory interevent above certain magnitude using lagged conditional probabilities. We find, in real data, that...
