Crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone): optical properties and computational modelling
(Royal Society of Chemistry, 2015-09-04)
Four new crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone) with 4,4'-bipyridine, 4-(2-pyridine-4-ethyl)pyridine, 1,3-di.4-pyridyl)propane and 2-hydroxy pyridine are reported. Adduct formation leads ...
DNA damage and induction of apoptosis in pancreatic cancer cells by a new dinuclear bis(triazacyclonane) copper complex
(Elsevier, 2015-01-26)
The dinuclear copper(II) complex [Cu-2{bcmp(-H)}(mu-OH)](NO3)(2)center dot H2O (1, bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol) has been synthesized and characterized by electrospray ionization mass ...
Bumblebee learning and memory is impaired by chronic exposure to a neonicotinoid pesticide.
(Nature Publishing Group, 2015-11-16)
Bumblebees are exposed to pesticides applied for crop protection while foraging on treated plants, with increasing evidence suggesting that this sublethal exposure has implications for pollinator declines. The challenges ...
Simplified approach to the prediction and analysis of temperature inhomogeneity in rapid compression machines
(American Chemical Society, 2015-11-03)
Substantial progress has been made in understanding and reducing temperature inhomogeneity in rapid compression machines (RCMs) with the help of computational modeling. To date, however, it has not been possible to investigate ...
New Zealand geothermal power plants as critical facilities: an active fault avoidance study in the Wairakei Geothermal Field, New Zealand
(International Geothermal Association, 2015-04-19)
Active faults in rifts commonly provide high crustal permeability and control geothermal fluid pathways. However, active faults can also pose surface deformation hazards to geothermal power plants and associated infrastructure. ...
Fracture width and spacing distributions from borehole televiewer logs and cores in the Rotokawa Geothermal Field, New Zealand
(International Geothermal Association, 2015-04-19)
The successful targeting of permeable fractures in geothermal fields is aided by understanding the spatial and geometric characteristics of fracture populations. Studies of numerous outcrop, and a limited number of geothermal ...
Modelling fluid flow through fractured rock: Examples using TVZ geothermal reservoirs
(New Zealand Geothermal Workshop, 2015-11-18)
Geothermal resources are often hosted within volcanic, plutonic, and basement-type lithologies. As such their matrix permeability can be very low and the transport and circulation of geothermal fluids will be dominated by ...
A review of the Rotokawa Geothermal Field, New Zealand
(Elsevier, 2015-07-29)
The Rotokawa Geothermal Field of New Zealand has seen significant development over the last 20 years and has been the study site for new and innovative geological and geothermal research. This includes the one of the first ...
Thermodynamics of linear and star polymers at fluid interfaces
(Royal Society of Chemistry, 2015)
Performing molecular dynamics simulations on model systems we study the structural changes and thermodynamic stability of polymers of varying topology (linear and star-shaped) at interface between two liquids. We find that ...
Low-content quantification in powders using Raman spectroscopy: a facile chemometric approach to sub 0.1% limits of detection.
(American Chemical Society, 2015-02-23)
A robust and accurate analytical methodology for low-content (<0.1%) quantification in the
solid-state using Raman spectroscopy, sub-sampling, and chemometrics was demonstrated using
a piracetam–proline model. The method ...
