Dissimilatory nitrogen reduction in intertidal sediments of a temperate estuary: small scale heterogeneity and novel nitrate-to-ammonium reducers [PDF]

open access: yes, 2015
The estuarine nitrogen cycle can be substantially altered due to anthropogenic activities resulting in increased amounts of inorganic nitrogen (mainly nitrate).

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

open access: yesNano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

A novel aerobic-anoxic biological filter for nitrogen removal from UASB effluent using biogas compounds as electron donors for denitrification

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2012
The performance of a new trickling filter (TF) configuration composed of an upper compartment for nitrification and a lower compartment for denitrification of effluent from a UASB reactor treating domestic sewage was evaluated.

Structure–Performance Correlation in PAN Nanofibers Reinforced With Carbon Nanotubes and Graphene Nanoplatelets

open access: yesPolymer Engineering &Science, EarlyView.
Electrospun polyacrylonitrile (PAN) fibers reinforced with carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) exhibit enhanced dielectric properties due to improved interfacial polarization and conductive network formation. Hybrid nanofillers enable morphology control and synergistic tuning of electrical performance, offering a promising route ...

Metabolic coupling between soil aerobic methanotrophs and denitrifiers in rice paddy fields

open access: yesNature Communications
Paddy fields are hotspots of microbial denitrification, which is typically linked to the oxidation of electron donors such as methane (CH4) under anoxic and hypoxic conditions.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

open access: yes, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Global Nitrous Oxide Production Determined by Oxygen Sensitivity of Nitrification and Denitrification

open access: yesGlobal Biogeochemical Cycles, 2018
The ocean is estimated to contribute up to ~20% of global fluxes of atmospheric nitrous oxide (N2O), an important greenhouse gas and ozone depletion agent. Marine oxygen minimum zones contribute disproportionately to this flux.

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Biokinetics Of microbial consortia using biogenic sulfur as a novel electron donor for sustainable denitrification [PDF]

open access: yes, 2018
In this study, the biokinetics of autotrophic denitrification with biogenic S0 (ADBIOS) for the treatment of nitrogen pollution in wastewaters were investigated. The used biogenic S0, a by-product of gas desulfurization, was an elemental microcrystalline

Implementing potential climate‐smart practices through diverse partnerships

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented
