High-precision measurements of seawater Pb isotope compositions by double spike thermal ionization mass spectrometry [PDF]

open access: yes, 2014
A new method for the determination of seawater Pb isotope compositions and concentrations was developed, which combines and optimizes previously published protocols for the separation and isotopic analysis of this element.

Perceptions and Acceptance of Desalinated Seawater for Irrigation: A Case Study in the Níjar District (Southeast Spain) [PDF]

open access: yes, 2017
In the context of increasing demand for irrigation water—but, at the same time, with the constraints in the supply from traditional resources—desalinated seawater has been recognized as one of the alternative sources of water to increase the supply for ...

Marine aerobic biofilm as biocathode catalyst [PDF]

open access: yes, 2010
Stainless steel electrodes were immersed in open seawater and polarized for some days at − 200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen.

Comparative genome-centric analysis reveals seasonal variation in the function of coral reef microbiomes [PDF]

open access: yes, 2020
Microbially mediated processes contribute to coral reef resilience yet, despite extensive characterisation of microbial community variation following environmental perturbation, the effect on microbiome function is poorly understood.

Effects of low seawater pH on the marine polychaete Platynereis dumerilii [PDF]

open access: yes, 2015
An important priority for any organism is to maintain internal cellular homeostasis including acidbase balance. Yet, the molecular level impacts of changing environmental conditions, such as low pH, remain uncharacterised.

The use of algorithms to predict surface seawater dimethyl sulphide concentrations in the SE Pacific, a region of steep gradients in primary productivity, biomass and mixed layer depth [PDF]

open access: yes, 2011
Dimethyl sulphide (DMS) is an important precursor of cloud condensation nuclei (CCN), particularly in the remote marine atmosphere. The SE Pacific is consistently covered with a persistent stratocumulus layer that increases the albedo over this large ...

Modification of Urushiol Derivatives by Liquid Crystal Epoxy Resin

open access: yesInternational Journal of Polymer Science, 2015
Urushiol derivatives have vast potentials for using as coating materials. However, the cured coatings are quite brittle, limiting their applications. In this study, urushiol-furfural (UFUR) was chosen as an example of urushiol derivatives and a liquid ...
