Resonant Raman Scattering by quadrupolar vibrations of Ni-Ag Core-shell Nanoparticles [PDF]

Phys. Rev. B, 65 (2002) 165422, 2002
Low-frequency Raman scattering experiments have been performed on thin films consisting of nickel-silver composite nanoparticles embedded in alumina matrix. It is observed that the Raman scattering by the quadrupolar modes, strongly enhanced when the light excitation is resonant with the surface dipolar excitation, is mainly governed by the silver ...

Evaluation of \u3cem\u3eRhodococcus equi\u3c/em\u3e Susceptibility to Silver Nanoparticle Antimicrobials [PDF]

, 2020
Rhodococcus equi is a significant cause of pneumonia in foals and immunocompromised humans. Antimicrobial resistance among R. equi isolates has developed as a consequence of inappropriate stewardship and bacterial evolution, leading to an increased rate ...

Rapid evolution of silver nanoparticle resistance in Escherichia coli

Frontiers in Genetics, 2015
The recent exponential increase in the use of engineered nanoparticles (eNPs) means both greater intentional and unintentional exposure of eNPs to microbes. Intentional use includes the use of eNPs as biocides.

Plasmon-enhanced second harmonic generation in semiconductor quantum dots close to metal nanoparticles [PDF]

Papers in Physics 3, 030002 (2011), 2011
We report the enhancement of the optical second harmonic signal in non-centrosymmetric semiconductor CdS quantum dots, when they are placed in close contact with isolated silver nanoparticles. The intensity enhancement is about 1000. We also show that the enhancement increases when the incoming laser frequency $\omega$ is tuned toward the spectral ...

From Silver Nanoparticles to Thin Films: Evolution of Microstructure and Electrical Conduction [PDF]

Journal of Physics and Chemistry of Solids 70 (2009) 459--465, 2011
Silver nanoparticles embedded in a dielectric matrix are investigated for their potential as broadband-absorbing optical sensor materials. This contribution focuses on the electrical properties of silver nanoparticles at various morphological stages. The electrical current through thin films, consisting of silver nanoparticles, was characterized as a ...

Yeast-derived biosynthesis of silver/silver chloride nanoparticles and their antiproliferative activity against bacteria [PDF]

, 2016
Here, we provide the first evidence of yeast strains assisted Ag/AgCl-NPs production in vitro. The formed nanoparticles were characterized by spectroscopic and electron microscopy approaches. UV-vis supported the biosynthesis. TEM analysis evidenced that
