Spectral and directional reshaping of fluorescence from dye molecules embedded in self-assembled hybrid plasmonic-photonic crystals has been examined. The hybrid crystals comprise two-dimensional hexagonal arrays of dye-doped dielectric nanospheres, capped with silver semishells. Comparing the reshaped fluorescence spectra with measured transmission/reflection spectra and numerical calculations...

An absorptive metasurface based on film-coupled colloidal silver nanocubes is demonstrated. The metasurfaces are fabricated using simple dip-coating methods and can be deposited over large areas and on arbitrarily shaped objects. The surfaces show nearly complete absorption, good off-angle performance, and the resonance can be tuned from the visible to the near-infrared.

Two topical MRSA eradication regimes were compared in hospital patients: a standard treatment included mupirocin 2% nasal ointment, chlorhexidine gluconate 4% soap, silver sulfadiazine 1% cream versus a tea tree oil regimen, which included tea tree 10% cream, tea tree 5% body wash, both given for five days. One hundred and fourteen patients received standard treatment and 56 (49%) were cleared ...

Objective(s): The aim of this study was to evaluate the effects of Malva sylvestris aqueous extract on cutaneous wound healing in BALB/c mice. Materials and Methods: Twenty seven male BALB/c mice (2.5 months of age) were used. A cut wound (superficial fascia depth) was made locally. The mice were then divided into three groups: the first, second and third groups received topical administration ...

Extended chain polymers [Ag(5){S(2)P(OEt)(2)}(4)(PF(6))](n), (1) could be converted to clusters of the type, [Ag(8)(X){S(2)P(OEt)(2)}(6)](PF(6)) [X = F (2); Cl (3); H (4)], by the addition of appropriate anions, of which [Ag(8)(H){S(2)P(OEt)(2)}(6)](+) showed a unique tetracapped-tetrahedral Ag(8) core and contained Ag-mu-H-Ag linkages.

The optimization of the silver halide-sensitized gelatin process is analyzed by considering the bleaching action, the influences of the developer, and the hardening modulation process.

The efficiency of noise gratings recorded with single-beam exposures in bleached silver halide emulsions is analyzed as a function of the polarization state of the readout wave. Experimental results are presented and discussed on the basis of a theoretical model that considers both a linear and a nonlinear relation between the refractive-index modulation and the exposure. The dependence of the ...

was shorter than that of the controls (7.1 days) and the total amount of saline required was less in the sulphadiazine-treated cases than in the controls. Chu, Huang, Chang arid Kao (1946) report the treatment of 25 cases of cholera with sulphadiazine and compare the result with that of 29 cases not treated with sulphadiazine and claim efficiency for sulphadiazine on clinical data. The results ...
