Nitrogen, soils and environment [PDF]

open access: yes, 2010
The article discusses the risk of damaging the environment brought by nitrogen fertilisers which are used for increasing agricultural productivity. The oxidation of ammonium allows for the formation of nitrate. Troposphere ozone and aerosols are produced

Phenolic Profiles, Antioxidant Properties and Predicted Glycaemic Index of Bread Sweetened With Date Syrup in Comparison With Granulated Sugar

open access: yesFood Chemistry International, EarlyView.
Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The

ZeroWasteWater: short-cycling of wastewater resources for sustainable cities of the future [PDF]

open access: yes, 2010
Sewage treatment relies mainly on conventional activated sludge (CAS) systems, reaching sufficiently low pollutant effluent levels. Yet, CAS has a low cost-effectiveness and recovery potential and a high electricity demand and environmental footprint. By

Alloy Solutions for Ammonia Cracking: A Review

open access: yesMaterials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Entropy production minimization in a tubular ammonia synthesis reactor: a mathematical optimization approach with variable geometry and heat flux control

open access: yesFrontiers in Energy Research
Ammonia is one of the most widely produced chemicals worldwide and is increasingly considered a promising hydrogen carrier for energy storage. We propose a novel thermodynamic optimization strategy for tubular ammonia reactors based on second-law ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.
