The depth specific significiance, relative abundance and phylogeography of anaerobic ammonium oxidation (anammox) in marine and estuarine sediments

, 2009
PhDThe availability of fixed forms of nitrogen is critical to the regulation of primary production. Until recently, denitrification (the sequential reduction of NO3 -, through NO2 - , to di-nitrogen gas) was recognised as the only significant pathway

Comparative Effects of White and Black Garlic on the Technological, Nutritional, and Sensory Properties of White and Whole Wheat Bread

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The response of bread systems to ingredient enrichment varies depending on flour composition and matrix structure. This study investigated the impact of white garlic (WG) and black garlic (BG) enrichment (1%–7%) on the technological properties, composition, antioxidants, and sensory characteristics of refined white ...

Electrochemically Co-Deposition of Palladium Nanoparticles and Poly(1, 5-diaminonaphthalene) onto Multiwalled Carbon Nanotubes (MWCNTs) Modified Electrode and its Application for Amperometric Determination of Nitrite

International Journal of Electrochemical Science, 2019
In this article, palladium nanoparticles (PdNPs) and 1, 5- diaminonaphthalene (1, 5-DAN) were electrochemically co-deposited onto multiwalled carbon nanotubes (MWCNTs) modified glassy carbon electrode (PdNPs-poly(1, 5-DAN)/MWCNTs/GCE). The morphology and

Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

Carbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.

Betanin inhibits the myeloperoxidase/nitrite-induced oxidation of human low-density lipoproteins [PDF]

, 2007
Production of nitrogen dioxide by the activity of myeloperoxidase (MPO) in the presence of nitrite is now considered a key step in the pathophysiology of low-density lipoprotein (LDL) oxidation.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
