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

open access: yesChemistry – 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.

Nitrite Removal Using Ion Exchange Resin: Batch vs. Fixed Bed Performance

open access: yes, 2015
Nitrite is an important pollutant appearing in the large amount of wastewater from flue gas denitrification process. Its removal is essential for wastewater discharge or reuse.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

NADPH oxidase and xanthine oxidoreductase as targets and regulators of the nitrate-nitrite-nitric oxide pathway

open access: yes, 2016
Overproduction of reactive oxygen species (ROS) by NADPH oxidase (NOX) and xanthine oxidoreductase (XOR) with a concomitant decrease in the bioavailability of nitric oxide (NO) from eNOS contributes to the development of cardiovascular and metabolic ...

Dinuclear Copper(I) Complexes Featuring Metal–Metal Interactions and a μ2‐Bridging Phosphane With Additional Olefinic Binding Sites

open access: yesChemistry – A European Journal, EarlyView.
A Cu2P triangle captured in a tetrapodal phosphane tris(olefin) ligand, where all binding forces are weak apart from the Cu─P interaction. ABSTRACT The molecule Ptrop3 contains in each trop unit (trop = dibenzo[a,d]cyclohepten‐5‐yl) a rigid central seven‐membered ring with an olefinic binding site making Ptrop3 potentially a tetradentate ligand ...

The nitrite anion: the key intermediate in alkyl nitrates degradative mechanism.

open access: yes, 2007
Alkyl nitrates, _in vivo_, are metabolized to yield nitric oxide, and thiol groups are considered necessary cofactors. This statement is based on studies that underline how these species potentiate hemodynamic responsiveness to nitrates in patients with ...

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

open access: yesChemistry – 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.

A simple miniaturised photometrical method for rapid determination of nitrate and nitrite in freshwater [PDF]

open access: yes, 2010
A rapid, simple miniaturised photometrical method was developed for the determination of nitrate and/or nitrite in freshwater samples. All procedures, including sample buffering, reduction by copperised cadmium granules, colour development and absorbance
