Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

open access: yesAdvanced Science, EarlyView.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.

The Carboxyl-Terminal Segment of Apolipoprotein A-V Undergoes a Lipid-Induced Conformational Change [PDF]

open access: yes, 2010
Apolipoprotein (apo) A-V is a 343-residue, multidomain protein that plays an important role in regulation of plasma triglyceride homeostasis. Primary sequence analysis revealed a unique tetraproline sequence (Pro293-Pro296) near the carboxyl terminus of ...

Testing deep placement of an 15N tracer as a method for in situ deep root phenotyping of wheat, barley and ryegrass

open access: yesPlant Methods, 2019
Background Deep rooting is one of the most promising plant traits for improving crop yield under water-limited conditions. Most root phenotyping methods are designed for laboratory-grown plants, typically measuring very young plants not grown in soil and

Dark Septate Endophytic Fungi Help Tomato to Acquire Nutrients from Ground Plant Material

open access: yesFrontiers in Microbiology, 2017
Dark septate endophytic (DSE) fungi are facultative biotrophs that associate with hundreds of plant species, contributing to their growth. These fungi may therefore aid in the search for sustainable agricultural practices.

Food resources of stream macroinvertebrates determined by natural-abundance stable C and N isotopes and a 15N tracer addition [PDF]

open access: yes, 2000
Trophic relationships were examined using natural-abundance 13C and 15N analyses and a 15N-tracer addition experiment in Walker Branch, a 1st-order forested stream in eastern Tennessee.

The Effect of N-Terminal Cyclization on the Function of the HIV Entry Inhibitor 5P12-RANTES. [PDF]

open access: yes, 2017
Despite effective treatment for those living with Human Immunodeficiency Virus (HIV), there are still two million new infections each year. Protein-based HIV entry inhibitors, being highly effective and specific, could be used to protect people from ...

15N excitation contribution to 48Ca(16O, 15N)49Sc reaction

open access: yesPhysics Letters B, 1980
Abstract The effect of 15 N excitation process is studied in the reaction 48 Ca( 16 O, 15 N) 49 Sc. The excitation process is included into a generalized non-local optical potential for a scattersing 15 N- 49 Sc and is found to be responsible for a shift of a grazing peak in the exact finite-range DWBA calculation.

The contribution of grass and clover root turnover to N leaching [PDF]

open access: yes, 2010
Sources of inorganic and organic N leaching from grass-clover mixtures at field sites in Denmark, Germany and Iceland were investigated. Grass or clover was labelled with 15N-urea four times (autumn 2007, spring, summer and autumn 2008) prior to the ...

Revision of the 15N(p,{\gamma})16O reaction rate and oxygen abundance in H-burning zones

open access: yes, 2011
The NO cycle takes place in the deepest layer of a H-burning core or shell, when the temperature exceeds T {\simeq} 30 {\cdot} 106 K. The O depletion observed in some globular cluster giant stars, always associated with a Na enhancement, may be due to ...
