We directly demonstrate an improvement in the radiative decay rate of dye molecules near multilayer hyperbolic metamaterials (HMMs). Our comprehensive study shows a radiative decay rate for rhodamine 800 (Rh800) that is several times higher due to the use of HMM samples as compared to dielectric substrates. This is also the first experimental demonstration that multilayer hyperbolic metamateria...

objective the aim of this study was to compare the sensitivity and specificity of acid fast and auramine-rhodamine staining and multiplex pcr for the detection of mycobacterium tuberculosiscomplex and non tuberculosis mycobacteria on formalin fixed paraffin embedded tissues (ffpe) materials and methods forty cases of ffpe pleural and bronchial tissue with chronic granulomatous inflammation and ...

Modified rhodamine 6G molecules (Rh-Al or Rh-Aln) with polymerizable double bonds had been copolymerized with 1,8-naphthalimide derivatives. In copolymers PRNAM, naphthalimide moieties are connected to rhodamine moieties at nitrogen atom of rhodamine moiety, and in copolymers PRNM naphthalimide moieties are connected to rhodamine moieties at ester group of rhodamine moiety. We report on their p...

The effect of temperature on absorption spectra of Rhodamine 6G at concentrations of 10 and 10 M in water:ethanol solutions of various ethanol content was studied. The dimeric molecular fraction of Rhodamine 6G (10 M) was found as a function of temperature and ethanol content in the aqueous solution. It was shown that the absorption spectrum of Rhodamine 6G dimers (10 M) is dependent on tempera...

This study aimed to investigate the effect of Rhodamine B exposure on oxidative stress and cervical epithelial cells proliferation in the uterus. Twenty eight female Wistar albino rats were divided into four groups (n = 7 each): one control (untreated) group; and three Rhodamine B groups at several doses (4.5, 9, 18 mg/200 g body weight/day) for 36 days. Colometric analysis of malondialdehyde (...

Use of soy protein concentrate and carboxy methyl cellulose as fat substitutes in the production Beji-Bersagh cake

in this work, zno/sio2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on zno/sio2 nanoparticles by photoreductive method. samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infrared spectroscopy (ft-ir). the xrd patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...

We have developed quantum dot probes for detecting trypsin (Try) and trypsin inhibitor (TI) in aqueous solutions through fluorescence resonance energy transfer (FRET). Green-fluorescent CdTe quantum dots (QDs) served as the energy donors and rhodamine isothiocyanate (RITC) conjugated to bovine serum albumin (BSA-RITC) was the acceptor. By simply mixing the two fluorophores, FRET occurred when B...
