The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...

Study on nitrogen removal in mixotrophic denitrification system driven by composite filter materials

Gongye shui chuli
NH4+-N in refinery wastewater is completely converted into NO3--N after biochemical treatment, resulting in extremely low C/N ratio in the effluent. The traditional heterotrophic denitrification processes require external carbon sources, which leads to ...

Biological denitrification

Hrvatski časopis za prehrambenu tehnologiju, biotehnologiju i nutricionizam, 2021
Ubrzani napredak industrije, poljoprivrede i domaćinstva su pogodovali povišenim koncentracijama dušika u vodenom ekosustavu, što uzrokuje eutrofikaciju. Dušik se iz otpadne vode uklanja procesom biološke denitrifikacije. U ovom preglednom radu dan je osvrt na denitrifikaciju, s aspekta mikroorganizama, koncentracije otopljenog kisika, donora i ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Warm‐wet transition restructures arid lake microbiomes and functional potential

iMetaOmics, EarlyView.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.
