Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

A Schematic Two Overlapping-Band Model for Superconducting Sulfur Hydrides: The Isotope Mass Exponent

open access: yesAdvances in Condensed Matter Physics, 2019
The high value of the isotope shift in sulfur hydrides supports a phonon-mediated pairing scenario of superconductivity for these high-temperature superconductors which are consistent with the Bardeen–Cooper–Schrieffer (BCS) framework.

Paediatric development of radiopharmaceutical imaging agents and radioligand therapeutics

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract This review focuses on the development of radiopharmaceutical imaging agents and radioligand therapeutics for paediatric use. Nuclear medicine plays an important role in the diagnosis and treatment of various childhood conditions, including cancers, infections and brain disorders.

Stable isotope phenotyping via cluster analysis of NanoSIMS data as a method for characterizing distinct microbial ecophysiologies and sulfur-cycling in the environment

open access: yesFrontiers in Microbiology, 2016
Stable isotope probing (SIP) is a valuable tool for gaining insights into ecophysiology and biogeochemical cycling of environmental microbial communities by tracking isotopically labeled compounds into cellular macromolecules as well as into byproducts ...

Evaluation of a pantoprazole and 4‐desmethylpantoprazole‐sulfate metabolic ratio as a novel CYP2C19 phenotyping method

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims CYP2C19 is one of the most important pharmacogenes, and its activity is highly variable due to factors such as genetics or drug–drug interactions. Due to the lack of an appropriate endogenous CYP2C19 biomarker, surrogate methods to assess its activity are warranted.

Nanomolar-scale sulfate sulfur isotope analysis using a combined ion chromatography–barite precipitation and nano-EA/IRMS

open access: yesProgress in Earth and Planetary Science
We report a newly developed method for analyzing the sulfur isotope ratio (34S/32S) of trace amounts of sulfate. This method consists of two steps: 1) isolation of sulfate via anion chromatography with fraction collection (IC-FC), and 2) precipitation of

SULFUR ISOTOPIC COMPOSITION OF SULFIDES FROM THE DESTRUCTION PRODUCTS OF PALEOSMOKER FROM THE YUBILEYNOE VHMS DEPOSIT (SOUTHERN URALS) [PDF]

open access: yesМинералогия, 2015
Variations in sulfur composition of sulfides from fragments of the paleosmoker chimneys, sulfide turbidites, and products of their seafloor alteration are determined.

Reduced sulfur in euxinic sediments of the Cariaco Basin : Sulfur isotope contraints on organic sulfur formation

open access: yes, 2003
Reduced sulfur accumulation in Holocene and latest Pleistocene euxinic marine sediments from the Cariaco Basin, Venezuela, was investigated to constrain the timing and possible pathways of organic matter (OM) sulfurization.
