Seasonal variation in the xylem sap composition of six Australian trees and shrubs

In recent years, xylem sap composition has been shown to affect xylem hydraulics. However, information on how much xylem sap composition can vary across seasons and specifically under drought stress is still limited. We measured xylem sap chemical composit ...

Deriving Major Ion Concentrations at High Resolution from Continuous Electrical Conductivity Measurements in Karst Systems

Paolo Benettin

Time series of hydrochemical parameters support the investigation of dominant karst hydrological processes and conceptual model structures. Nevertheless, high costs for sample collection and analyses cause hydrochemical data to be rarely available at a suf ...

The influence of climate on water chemistry states and dynamics in rivers across Australia

Camille Roland Marie Minaudo

For effective water quality management and policy development, spatial variability in the mean concentrations and dynamics of riverine water quality needs to be understood. Using water chemistry (calcium, electrical conductivity, nitrate-nitrite, soluble r ...

High-temperature conductivity evaluation of Nb doped SrTiO 3 thin films: Influence of strain and growth mechanism

Vasiliki Tileli

Doped SrTiO3 thin films, 55 nm thick, were epitaxially grown by Pulsed Laser Deposition with niobium contents ranging from 2 to 5 mol% on SrTiO3 and LaAlO3 substrates. The different templates result in different growth defects, film growth mechanism and th ...

On the measured current in electrospinning

Tobias Schneider

The origin and scaling of the current measured during steady electrospinning of polymer solutions in organic solvents are considered. For a specified electric field strength E, flow rate Q, and conductivity K, the total measured current is shown empiricall ...

Alternative anode materials for methane oxidation in solid oxide fuel cells

Joseph Sfeir

Fuel Cells are electrochemical devices that are able to directly convert chemical energy to electrical energy, without any Carnot limitation. Hence, their energy efficiencies are relatively high. Among the various types of fuel cells, solid oxide fuel cell ...

Study and control of the conductivity of Nb-doped Bi4Ti3O12 for high temperature piezoelectric applications

Nava Setter, Dragan Damjanovic

Bismuth-based layered compounds have been considered during the last years as interesting materials fur high temperature piezoelectric applications, due to their stability and wide thermal range of the ferroelectric activity. The high electrical conductivi ...
