The role of Rayleigh anomalies in the coupling process of plasmonic gratings and the control of the emission properties of organic molecules.

We report the investigation of the influence of periodic metallic arrays on the emission properties of organic emitters. Beforehand, the study of the coupling process between nanoparticles through the analysis of the extinction spectra related to Rayleigh anomalies indicate the crucial role of those latter in defining the nature of the excited grating modes. The obtained results emphasis that Rayleigh Anomalies can be considered as the intermediate between individual plasmonic and collective photonic responses.

Alternatives to Fight Vancomycin-Resistant and .

Gram positive pathogens are a significant cause of healthcare-associated infections, with and being the most prevalent ones. Vancomycin, a last resort glycopeptide, is used to fight these bacteria but the emergence of resistance against this drug leaves some patients with few therapeutic options. To counter this issue, new generations of antibiotics have been developed but resistance has already been reported.

Opposite effect of vancomycin and D-Cycloserine combination in both vancomycin resistant Staphylococcus aureus and enterococci.

The increasing spread of antibiotic resistant bacteria is a major human health concern. The challenging development of new effective antibiotics has led to focus on seeking synergistic antibiotic combinations. Vancomycin (VAN) is a glycopeptide antibiotic used to treat Staphylococcus aureus and enterococci infections.

Multiwavelength generation from multi-nonlinear optical process in a 2D PPLT.

We have demonstrated multi-wavelength generation in a nonlinear photonic crystals of lithium tantalate. The optical parametric generation leads to second harmonic generation, sum-frequency generation and other frequency conversion in a cascade process. These conversions are assisted by all the optical nonlinear process involving χ and achieved by satisfying the quasi-phase matching conditions.

Exciton enhancement and exciplex quenching by plasmonic effect of Aluminum nanoparticle arrays in a blue organic light emitting diode.

We report the investigation of plasmonic effect of array of aluminum nanoparticles (Al-NPs) on blue micro-OLED subject to exciplex emission. N,N'-Di(1-naphthyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine (NPB) andcarbazol derivative 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP) have been used as the emitting layer (EML) and hole transport layer (HTL), respectively. For the reference µ-OLED without Al-NPs, we observed two emission peaks attributed to CBP emission and exciplex emission formed at the NPB/CBP (EML/HTL) interface.
