Caution on the use of NBS 30 biotite for hydrogen-isotope measurements with on-line high-temperature conversion systems.

Rapid communications in mass spectrometry : RCM

Qi H, Coplen TB, Olack GA, Vennemann TW.
PMID: 25132299
Rapid Commun Mass Spectrom. 2014 Sep 30;28(18):1987-94. doi: 10.1002/rcm.6983.

RATIONALE: The supply of NBS 30 biotite is nearly exhausted. During measurements of NBS 30 and potential replacements, reproducible δ(2)HVSMOW-SLAP values could not be obtained by three laboratories using high-temperature conversion (HTC) systems. The cause of this issue has...

Metal analysis in citrus sinensis fruit peel and psidium guajava leaf.

PMID: 21976824
Toxicol Int. 2011 Jul;18(2):163-7. doi: 10.4103/0971-6580.84271.

The determination of metal traces is very important because they are involved in biological cycles and indicate high toxicity. The objective of the present study is to measure the levels of heavy metals and mineral ions in medicinally important...

Can rye intake decrease risk of human breast cancer?.

Food & nutrition research

Adlercreutz H.
PMID: 21311613
Food Nutr Res. 2010 Nov 10;54. doi: 10.3402/fnr.v54i0.5231.

BACKGROUND: Rye contains more fibre and bioactive compounds than other cereals used for bread production. The fibre and compounds of the fibre complex could provide protection against breast cancer (BC).OBJECTIVE: To review the evidence and theoretical background for a...

Physico-chemical, sensory, and microbiological assessments of wheat-based biscuit improved with beniseed and unripe plantain.

Food science & nutrition

Agu HO, Okoli NA.
PMID: 25473504
Food Sci Nutr. 2014 Sep;2(5):464-9. doi: 10.1002/fsn3.135. Epub 2014 Jun 23.

The consumption of cereal foods such as biscuit has become very popular globally. Partial replacement of wheat flour with beniseed and unripe plantain flours rich in protein, vitamins, and minerals will increase nutrient, diversify utilization of beniseed and unripe...

Comparison between Gaussian-type orbitals and plane wave ab initio density functional theory modeling of layer silicates: talc [Mg3Si4O10(OH)2] as model system.

The Journal of chemical physics

Ulian G, Tosoni S, Valdrè G.
PMID: 24289338
J Chem Phys. 2013 Nov 28;139(20):204101. doi: 10.1063/1.4830405.

The quantum chemical characterization of solid state systems is conducted with many different approaches, among which the adoption of periodic boundary conditions to deal with three-dimensional infinite condensed systems. This method, coupled to the Density Functional Theory (DFT), has...

Progress in Nano-Engineered Anodic Aluminum Oxide Membrane Development.

Materials (Basel, Switzerland)

Poinern GEJ, Ali N, Fawcett D.
PMID: 28880002
Materials (Basel). 2011 Feb 25;4(3):487-526. doi: 10.3390/ma4030487.

The anodization of aluminum is an electro-chemical process that changes the surface chemistry of the metal, via oxidation, to produce an anodic oxide layer. During this process a self organized, highly ordered array of cylindrical shaped pores can be...

Modeling dynamics of (137)Cs in forest surface environments: Application to a contaminated forest site near Fukushima and assessment of potential impacts of soil organic matter interactions.

The Science of the total environment

Ota M, Nagai H, Koarashi J.
PMID: 26897402
Sci Total Environ. 2016 May 01;551:590-604. doi: 10.1016/j.scitotenv.2016.02.068. Epub 2016 Feb 18.

A process-based model for (137)Cs transfer in forest surface environments was developed to assess the dynamic behavior of Fukushima-derived (137)Cs in a Japanese forest. The model simulation successfully reproduced the observed data from 3year migration of (137)Cs in the...

Dehydration-driven stress transfer triggers intermediate-depth earthquakes.

Nature communications

Ferrand TP, Hilairet N, Incel S, Deldicque D, Labrousse L, Gasc J, Renner J, Wang Y, Green Ii HW, Schubnel A.
PMID: 28504263
Nat Commun. 2017 May 15;8:15247. doi: 10.1038/ncomms15247.

Intermediate-depth earthquakes (30-300 km) have been extensively documented within subducting oceanic slabs, but their mechanics remains enigmatic. Here we decipher the mechanism of these earthquakes by performing deformation experiments on dehydrating serpentinized peridotites (synthetic antigorite-olivine aggregates, minerals representative of...

Promoting the Adsorption of Metal Ions on Kaolinite by Defect Sites: A Molecular Dynamics Study.

Scientific reports

Li X, Li H, Yang G.
PMID: 26403873
