Microbiology Spectrum, 2022 Antibiotic-producing microorganisms usually require one or more self-resistance determinants to survive antibiotic production. The effectors of these mechanisms are proteins that inactivate the antibiotic, facilitate its transport, or modify the target ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Dynamical Recrossing in the Intercalation Process of the Anticancer Agent Proflavine into DNA [PDF]
The Journal of Physical Chemistry B, 2019 Intercalation into DNA is the interaction mode of some anthracycline antibiotics. Recently, the molecular mechanism of this process was explored using the static free energy landscape. Here we explore the dynamical effects in the intercalation of proflavine into DNA by calculating the transmission coefficient κ-providing a measure of the departure from

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

SYNTHESIS AND ANTINEOPLASTIC ACTIVITY OF CERTAIN TRIAZENE AND TRIAZENO-ACRIDINE COMBILEXIN DERIVATIVES [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 2007 Four series of bifunctional ligands have been synthesized as DNA-binding combilexins. These novel agents contain a triazenobenzene sulfonamide linker moiety that is attached to an intercalating acridine or acridone chromophore by a functionalized amide ...
