A Structural Comparison of a Series of Paramagnetic Transition Metal Complexes: The Interplay between Octahedral Distortion and Secondary Coordination Domains

James P. Flood, Hyunsung Min, Mohan Madhav Bhadbhade, Ruoming Tian et autres

Four new mononuclear complexes of the form [M L ]X 2 were synthesized using a previously reported ligand, tris((((1-(pyridin-4-yl)-1 H -imidazole-4-yl)methylene)amino)ethyl)ethane-1,2-diamine, L . The new metal complexes bearing Mn(II), Co(II), Ni(II), or Cu(II) have been characterized both in solution and in the …

Westerly wind shifts drove Southern Hemisphere mid-latitude peat growth since the last glacial

Zoë Thomas, Haidee Cadd, CHRIS S. M. TURNEY, Lorena Becerra‐Valdivia et autres

Abstract Extratropical peatlands in the Southern Hemisphere preserve detailed information on climatic and environmental change going back millennia. They are particularly valuable for understanding the evolution of the mid-latitude southern westerly winds (SWW), which play a major role in driving regional temperature …

Developing robust lake sediment chronologies using 210Pb, Pu and radiocarbon dating of pollen concentrates and macrofossil: A case study from Lake Surprise, Victoria, Australia

Asika Dharmarathna, Haidee Cadd, Cameron Barr, Alexander Francke et autres

The development of reliable sediment chronologies is crucial for accurate interpretations of decadal to century-scale palaeoenvironmental changes in the late Quaternary. Although radiocarbon dating of sedimentary sequences is commonly undertaken, not all the organic fractions are representative of atmospheric 14 C levels, …

Comprehensive chemical profiling of roadside soil and road dust of Delhi, India: Estimation of health risk and city fuel consumption

Manoj P. Singh, Saroj Bhattacharyya, Khorshed Chinu, Rabeya Akter et autres

Roadside soil and dust are relatively underexplored as sources of toxic metal exposure in the massively urbanized city of Delhi. Here we report a large-scale study of 44 elements analyzed at 33 sites. Environmental exposure to carcinogenic and non-carcinogenic risks from toxic …

The age and position of the southern boundary of prehistoric Polynesian dispersal

Atholl Anderson, Lorena Becerra‐Valdivia, Haidee Cadd, Christopher E. Marjo et autres

Abstract Prehistoric Polynesian voyaging into high latitudes with landfall in Antarctica remains a widely credited proposition. We examine it through archaeological and environmental evidence from the Subantarctic region of the southwest Pacific, focussing upon an extensive archaeological site at Sandy Bay on …

Fire-induced shifts in stalagmite organic matter mapped using Synchrotron infrared microspectroscopy

Liza K. McDonough, Micheline Campbell, Pauline C. Treble, Christopher E. Marjo et autres

Understanding organic matter (OM) in cave mineral deposits (speleothems) is essential for interpreting land use and climatic changes, and the incorporation of trace elements associated with organic compounds. However, the sources and composition of OM in speleothems are poorly understood due to …

Natural organic matter in groundwater: Carbon source or sink?

Helen Rutlidge, Liza K. McDonough, Phetdala Oudone, Martin S. Andersen et autres

Carbon plays an essential role in all biological processes on the earth and hence it is important to Mustin the environment. The concentration of organic matter in groundwater, with a global median of 1.0 mg C/L, is often significantly lower than in …

Conformational investigations on three large dinuclear triple helicates by single crystal X-ray diffraction

Kyle J. Howard-Smith, Matthew J. Wallis, James P. Flood, Hyunsung Min et autres

Abstract Three new dinuclear triple helicates were synthesised using a ditopic semi-rigid pyridylylimine ligand L , separated by a diphenoxy-biphenol spacer providing considerable length to the backbone. L and the new large dinuclear triple helicate complexes [Fe 2 L 3 ](BF 4 …

Spin crossover of a Fe( ii ) mononuclear complex induced by intermolecular factors involving chloride and solvent ordering

K Zhang, Matthew J. Wallis, Alexander R. Craze, Shinya Hayami et autres

anion (2) led to a markedly different crystal packing arrangement, and engendered SCO activity. This has been correlated to the lower crystal packing density in 2 and the coordination complex conformational differences arising due to the packing motifs of 1 and 2. …
