Formation of CuO nanorods and their bundles by an electrochemical dissolution and deposition process
TL;DR: In this article, the formation of the NRs and their bundles was explained by an aggregation mechanism, and a transformation of the Cu phase in the as-deposited sample to a single CuO phase was effected by an annealing treatment at 500°C.

CuO NANOPARTICLES: SYNTHESIS, CHARACTERIZATION AND THEIR BACTERICIDAL EFFICACY
TL;DR: In this paper, copper oxide (CuO) nanoparticles were synthesized and characterized by using X-ray diffraction, Fourier transforms infrared spectroscopy (FT-IR), and scanning electron microscope (SEM) with Energy Dispersive X -ray Analysis (EDX) techniques.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.

Evidence for stripe correlations of spins and holes in copper oxide superconductors
TL;DR: In this article, the authors examined the possibility that this effect is related to dynamical two-dimensional spin correlations, incommensurate with the crystal lattice, that have been observed in La2-SrxCuO4 by neutron scattering.

Metal Oxide Nanoparticles as Bactericidal Agents
TL;DR: In this paper, reactive magnesium oxide nanoparticles and halogen (Cl2, Br2) adducts of these MgO particles were allowed to contact certain bacteria and spore cells, which yield insight into the biocidal action of these nanoscale materials.
