Size-Controlled Water-Soluble Ag Nanoparticles [PDF]

, 2007
Ag nanoparticles of two different sizes (1 and 4 nm) were prepared within an apoferritin cavity by using an Ag+-loaded apoferritin as a nanoconfined environment for their construction.

MARK-AGE biomarkers of ageing [PDF]

Mechanisms of Ageing and Development, 2015
Many candidate biomarkers of human ageing have been proposed in the scientific literature but in all cases their variability in cross-sectional studies is considerable, and therefore no single measurement has proven to serve a useful marker to determine, on its own, biological age.

Well-designed g-C3N4 nanosheet incorporated Ag loaded Er0.05La0.95FeO3 heterojunctions for isoamyl alcohol detection

Journal of Advanced Ceramics
Because the volatile content of isoamyl alcohol increases sharply on the seventh day of wheat mildew infection, isoamyl alcohol can be used as an early biomarker of wheat mildew infection.

Growth of epitaxially oriented Ag nanoislands on air-oxidized Si(111)-(7x7) surfaces: Influence of short range order on the substrate

, 2010
Clean Si(111)-(7{x7) surfaces, followed by air-exposure, have been investigated by reflection high energy electron diffraction (RHEED) and scanning tunneling microscopy (STM).

Hydrogen Gas Sensing Performances of p-Type Mn₃O₄ Nanosystems: The Role of Built-in Mn₃O₄/Ag and Mn₃O₄/SnO₂ Junctions

Nanomaterials, 2020
Among oxide semiconductors, p-type Mn3O4 systems have been exploited in chemo-resistive sensors for various analytes, but their use in the detection of H2, an important, though flammable, energy vector, has been scarcely investigated.

Strain-Dependence of Surface Diffusion: Ag on Ag(111) and Pt(111)

, 1997
Using density-functional theory with the local-density approximation and the generalized gradient approximation we compute the energy barriers for surface diffusion for Ag on Pt(111), Ag on one monolayer of Ag on Pt(111), and Ag on Ag(111). The diffusion

Supramolecular Assembly of Ag(I) Centers: Diverse Topologies Directed by Anionic Interactions. [PDF]

, 2014
Ag(I)-Ag(I) interactions in supramolecular structures have been achieved through the use of structural support from the ligand frames. In structures involving simple ligands like pyridine, strong π-π interaction leads to spatial ordering of the ...
