Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Modeling long term Enhanced in situ Biodenitrification and induced heterogeneity in column experiments under different feeding strategies [PDF]

open access: yes, 2016
Enhanced In situ Biodenitrification (EIB) is a capable technology for nitrate removal in subsurface water resources. Optimizing the performance of EIB implies devising an appropriate feeding strategy involving two design parameters: carbon injection ...

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

open access: yesAdvanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Testing our understanding of Arctic denitrification using MIPAS-E satellite measurements in winter 2002/2003 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2006
Observations of gas-phase HNO3 and N2O in the polar stratosphere from the Michelson Interferometer for Passive Atmospheric Sounding aboard the ENVISAT satellite (MIPAS-E) were made during the cold Arctic winter of 2002/2003.

Denitrification pathways and rates in the sandy sediments of the Georgia continental shelf, USA

open access: yesGeochemical Transactions, 2005
Denitrification in continental shelf sediments has been estimated to be a significant sink of oceanic fixed nitrogen (N). The significance and mechanisms of denitrification in organic-poor sands, which comprise 70% of continental shelf sediments, are ...

A standardised method for measuring in situ denitrification in shallow aquifers: numerical validation and measurements in riparian wetlands [PDF]

open access: yes, 2003
A tracer test to examine in situ denitrification in shallow groundwater by a piezometer with a packer system used bromide as a tracer of dilution and acetylene (10%) to block the denitrification process at the nitrous oxide stage.

Uncovering Cystic Fibrosis Carrier: Insights From a Heterozygous CFTR‐F508del Rabbit Model

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disorder frequently associated with impaired mucociliary clearance and bacterial infection. Individuals carrying a single cystic fibrosis transmembrane conductance regulator (CFTR) mutation exhibit partial CFTR dysfunction and are increasingly recognized as being at risk ...
