Facile ligand substitution is observed when the ruthenium azido complex (PPh3)[Ru]-N3 (1; [Ru] = Tp(PPh3)Ru) treated with CH3CN, yielding nitrile-substituted (CH3CN)[Ru]-N3 (2). Alkylation, [3 + 2] cycloaddition, and catalytic reactions of 2 have been investigated. In case cycloaddition reactions, metal-bound heterocyclic complexes (CH3CN)[Ru]-N3C2(CO2Me)2 (3a), (CH3CN)[Ru]-N3C2HCO2Me (5), (CH3CN)[Ru]-N3C2HCN (6) are obtained from dimethyl acetylenedicarboxylate, methyl propiolate,...
In the field of chiral recognition, cyclic organic compounds, especially heterocyclic have attracted little attention and been rarely studied as substrates by means 1H NMR spectroscopy. this paper, enantiomers thiohydantoin derivatives, representing typical five-membered N,N-heterocycles, synthesized utilized for assignment absolute configuration analysis enantiomeric excess. All successfully differentiated with assistance novel tetraaza macrocyclic solvating agents (TAMCSAs) Surprisingly,...
Abstract. The Amery Ice Shelf (AIS), East Antarctica, has a layered structure, due to the presence of both meteoric and marine ice. In this study, thermal structure AIS its spatial pattern are evaluated analysed through borehole observations numerical simulations with Elmer/Ice, full-Stokes ice sheet/shelf model. area ice, near-isothermal basal layer up 120 m thick is observed, which closely conforms pressure-dependent freezing temperature seawater. experiencing melting, large gradients,...
Root rot disease is vital of Coptis chinensis, it has bursted in most producing area recent years, and caused severe damage. To identify the pathogenic fungi, Fusarium spp. fungi were isolated from root, which screened with inoculation on C. chinensis root plant, identified molecular morphological method. The 20 obtained, 5 displayed high pathogenicity. It was deduced that F. oxysporum, solani tricinctum pathogen, possibly pioneer pathogen disease. Among oxysporum dominant deserved to pay...
Enantiomers of a series tripeptide derivatives with three stereogenic centers (±)-G1-G9 have been prepared from d- and l-α-amino acids as guests for chiral recognition by 1H NMR spectroscopy. In the meantime, family tetraaza macrocyclic solvating agents (TAMCSAs) 1a-1d has synthesized d-phenylalanine (1 S,2 S)-(+)-1,2-diaminocyclohexane. Discrimination enantiomers was carried out in presence TAMCSAs The results indicate that can be effectively discriminated signals multiple protons...
The formation and evolution of an intracontinental basin triggered via the subduction or collision plates at continental margins can record tectonic processes. As a typical during Jurassic, Qaidam Basin in western China records how this extensional formed evolved response to distant collisional processes tectonism caused by stresses transmitted from convergent plate margins. Jurassic Basin, terms basin-filling architecture, sediment dispersal pattern properties, remains speculative; hence,...
Abstract. Projections of Antarctic Ice Sheet mass loss and therefore global sea level rise are hugely uncertain, partly due to how the ice sheet occurs at grounding line. The Wilkes Subglacial Basin (WSB), a vast region East sheet, is thought be particularly vulnerable deglaciation under future climate warming scenarios. However, projections loss, driven by line migration, known sensitive parameterisation ocean-induced basal melt floating shelves, specifically, adjacent – termed Grounding...

Recent studies have indicated that the migration of grounding line is extremely sensitive to basal melt in zone. Different representations melting at introduce significant uncertainties predictions ice mass loss and global sea level rise. However, there remains an absence targeted, systematic grounded real-domain, robustly representing partially floating cells sheet models a pressing technical challenge. This study delves into four distinct schemes within Wilkes Subglacial Basin (WSB) model,...
While the slow moving interior of Antarctic Ice Sheet is not prone to rapid change, fast flowing outlet glaciers may exhibit accelerations and unstable retreat in response ocean induced melting ice shelves. This motion only possible due sliding over bed, which dependent on presence, pressure, liquid water under sheet.  subglacial hydrologic system fed by in-situ caused mainly friction heat as slides its outflow feeds into shelf cavities across deep grounding lines.  Two-way...
Subglaical hydrology significantly influences the basal sliding that controls how fast ice sheets transport from land to oceans. The absence of hydrologic systems in sheet models is therefore a notable source uncertainty projected ice-mass loss and its subsequent impact on sea-level rise. Specifically, associated with representation effective pressure (the difference between subglacial water overburden pressure) lacks comprehensive investigation Antarctic rise projections. Here we use...
The photosynthetic physiological characteristics of Rorippa amphilia and sylvestris were studied by pot experiment under Cd stress, 7 treatments 0, 1, 5, 10, 50, 100, 200（mg·kg-1）respectively. results showed that, (1) Chla, chlb, Ch(la+b) changed little when the concentration in soil was less than 100 mg·kg-1. There no significant difference among treatments. When more or equal to mg·kg-1, all indexes decreased significantly, Chla/b increased gradually with increase stressful concentration;...
Root rot disease restricts the Coptis chinensis industry in Shizhu of Sichuan province. To disclose fungi composition and pathogen root,so as to prevent treat root disease,the C. 5 years from 4 areas were collected 3 seasons respectively. The isolated molecularly morphological identified,followed with population statistics. 437 isolated,belonging subphylum,11 classes,16 orders,22 families 28 genus There are great difference among compositions different area,year sampling season,while there...
Abstract This paper reports part of a study 3-year large project on international schools in China, where the landscape education has been recently transformed. The covid -19 pandemic, together with policy context reshaped schools. three-year investigates challenges as well opportunities that China are confronted post pandemic era and how successful principals enacted their leadership practices contextually diverse schools, by employing mixed-methods design. only demonstrates initial results...
