Mass spectrometry provides state of the art approaches for the identification and characterization of lipoxidized proteins/residues and the modifying species. Nevertheless, understanding the complexity of the functional effects of protein lipoxidation requires the use of additional methodologies. Herein, ...
Volatile organic compounds (VOCs) are considered one of the significant contributors to air pollution because they are toxic, difficult to remove, come from a wide range of sources, and can easily cause damage to the environment and human health. There i
Catalytic system using new ligands which, used in situ with nickel complex in zero oxidation state, make it possible to obtain polyolefin with very high activity even in presence of polar mediumdoi:US6818714 B1—SO 3 Y where Y=Li, Na, NH 4 + , NR″ 4 + (R″=C 1 -C 15 ...
This list is not exhaustive but allows to realize the large diversity of iron compounds available for industry as well as for living organisms. The redox potential of the Fe(II)/Fe(III) couple presents an extreme variability that can be finely tuned by the ligands (see Table 1). In ...
The majority of anticancer agents have a reduced or even complete loss of a therapeutic effect within hypoxic tumors. To overcome this limitation, research efforts have been devoted to the development of therapeutic agents with biological mechanisms of action that are independent of the oxygen concentr...

N-heterocyclic carbenes (NHCs) found numerous applications as ligands for transition metal complexes during the last two decades. Only recently, however, increasing attention is turning to high oxidation state organometallics with NHC ligands. A surprising number of stable complexes of that type have ...
A generic definition of oxidation state (OS) is formulated: “ The OS of a bonded atom equals its charge after ionic approximation ”. In the ionic approximation, the atom that contributes more to the bonding molecular orbital (MO) becomes negative. This
Lys-436 forms a cation-π interaction with the aromatic ring of Tyr-193, thereby lowering the pKa value and thus stabilizing the deprotonated state. We also assume that Tyr-479 stabilizes the deprotonated state of Tyr-193 by hydrogen bonding (FIGURE 2, FIGURE 3). Thus, these three amino ...
The structural polymorphism of the oxygen-evolving complex is of great significance to photosynthetic water oxidation. Employing density functional theory calculations, we have made further advisement on the interconversion mechanism of O5 transfer in the S2 state, mainly focusing on the potentiality of ...
