Chemical Composition of Lithiated Nitrodonickelates LiNiN: Evidence of the Intermediate Valence of Nickel Ions from Ion Beam Analysis and Calculations.

Lamellar lithiated nitridonickelates have been investigated from both experimental and theoretical points of view in a wide range of compositions. In this study, we show that the nickel ion in lamellar lithiated nitridonickelates adopts an intermediate valence close to +1.5.

LiNiN, a Promising Negative Electrode Material for Li-Ion Batteries with a Soft Structural Response.

The layered lithium nitridonickelate LiNiN has been investigated as a negative electrode in the 0.02-1.25 V vs Li/Li potential window.

Imidazolium-based titanium substrates against bacterial colonization.

Nosocomial infections are often induced by the presence of pathogenic organisms on the surface of medical devices or hospital equipment. Chemical modifications of the surface are recognized as efficient strategies to prevent bacterial adhesion but they may have a negative impact on the material's interaction with living tissues. Here we have developed a photoactivated method for the modification of titanium substrates.
