Ammonia-induced inhibition of manure-based continuous biomethanation process under different organic loading rates and associated microbial community dynamics
(2021)Three Continuously Stirred Tank Reactors (CTSRs) were operating at steady state conditions with Organic Loading Rates (OLR) of 2.09, 3.024 and 4.0 g VS L−1 d−1. Glucose was used as the sole factor for increasing the OLR, ... -
Assessment of the impact of three pesticides on microbial dynamics and functions in a lab-to-field experimental approach
(2018)The toxicity of pesticides on soil microorganisms is as an emerging area of concern. Novel and well-standardized tools could be now used to provide a robust assessment of the ecotoxicity of pesticides on soil microorganisms. ... -
Blame it on the metabolite: 3,5-dichloroaniline rather than the parent compound is responsible for the decreasing diversity and function of soil microorganisms
(2018)Pesticides are key stressors of soil microorganisms with reciprocal effects on ecosystem functioning. These effects have been mainly attributed to the parent compounds, while the impact of their transformation products ... -
A catastrophic change in a european protected wetland: From harmful phytoplankton blooms to fish and bird kill
(2022)Understanding the processes that underlay an ecological disaster represents a major scientific challenge. Here, we investigated phytoplankton and zooplankton community changes before and during a fauna mass kill in a ... -
Deep learning in water resources management: The case study of Kastoria lake in Greece
(2021)The effects of climate change on water resources management have drawn worldwide attention. Water quality predictions that are both reliable and precise are critical for an effective water resources management. Although ... -
The effect of biochar feedstock, pyrolysis temperature, and application rate on the reduction of ammonia volatilisation from biochar-amended soil
(2018)Ammonia (NH3) volatilisation is one of the most important causes of nitrogen (N) loss in soil-plant systems worldwide. Carbon-based amendments such as biochar have been shown to mitigate NH3 volatilisation in agricultural ... -
Effects of organic loading rate and hydraulic retention time on bioaugmentation performance to tackle ammonia inhibition in anaerobic digestion
(2021)Three continuously stirred-tank reactors fed with manure operating under high ammonia levels (5.0 g NH3-N L−1) and with increased organic loading rate (OLR), (2.09 R1, 3.02 R2 and 4.0 R3 g VS L−1 d−1), achieved through ... -
Electrocatalytic production of ammonia: Biomimetic electrode–electrolyte design for efficient electrocatalytic nitrogen fixation under ambient conditions
(2020)Electrocatalytic nitrogen reduction offers a vital approach for nitrogen fixation in a green and sustainable way, but the low solubility of nitrogen and the competitive hydrogen evolution reaction still impede its further ... -
Electrocatalytic reduction of nitrogen on FeAg/Si for ammonia synthesis: A simple strategy for continuous regulation of faradaic efficiency by controlling H+ ions transfer rate
(2021)Electrocatalytic nitrogen reduction offers a dream way to produce active nitrogen for agriculture and high-energy-dense carbon-free fuels for our blue planet. However, it suffers from extremely low faradaic efficiency ... -
An electrochemical method for the determination of concentration and diffusion coefficient of ammonia‑nitrogen gas mixtures
(2018)In the present investigation an electrochemical method for the determination of concentration and diffusion coefficient of ammonia in nitrogen (NH3/N2) is proposed by the means of a solid-state amperometric sensor based ... -
Estimation of ground-level O3 using soft computing techniques: case study of Amritsar, Punjab State, India
(2022)Over the years, many organizations across the globe have conducted various studies pertaining to air pollution and its ill effects. The results of these studies substantially conclude that a plethora of people succumbs to ... -
Highly efficient electrocatalysts for oxygen reduction reaction: Nitrogen-doped PtNiMo ternary alloys
(2019)The relatively low efficiency of the reaction of oxygen reduction (ORR) remains among the main obstacles for hydrogen fed proton exchange membrane fuel cells (H-PEMFCs) commercialization. In the present work, PtNiMo ternary ... -
Identification and expression profiling of rosmarinic acid biosynthetic genes from Satureja khuzistanica under carbon nanotubes and methyl jasmonate elicitation
(2019)Satureja khuzistanica is a medicinal herb endemic to Iran which can serve as a source of rosmarinic acid (RA). In the present study, the effect of different concentrations of methyl jasmonate (MeJA) and multi-walled carbon ... -
Land spreading of wastewaters from the fruit-packaging industry and potential effects on soil microbes: Effects of the antioxidant ethoxyquin and its metabolites on ammonia oxidizers
(2016)Thiabendazole (TBZ), imazalil (IMZ), ortho-phenylphenol (OPP), diphenylamine (DPA), and ethoxyquin (EQ) are used in fruitpackaging plants (FPP) with the stipulation that wastewaters produced by their application would be ... -
