The Time-resolved fluorescence spectroscopy (TR-FS) has the potential to differentiate tumor and normal tissue in real time during surgical excision. In this manuscript, we describe the design of a novel TR-FS device, along with preliminary data on detection accuracy for fluorophores in a mixture. The instrument is capable of near real-time fluorescence lifetime acquisition in multiple spectral...

The utilization of solar energy, an abundant and renewable resource, shows great promise. Various technologies have been employed to capture this vast energy potential. In study, the effectiveness natural dye-sensitized cells (DSSCs) was explored through experimental computational methods. Organic dyes derived from specific plant species were examined, with a solvent mixture ethanol, methanol, ...

Microplastics as environmental pollutants are increasingly a source of alarm. The characterization microplastics will be necessary to discriminate from other types particles. To specific microplastics, plastic-adsorbable fluorescent dyes used, the stained separated dye-microplastic mixture by filtration, and type staining is analyzed microscopy. In this study, realize in situ analysis staining,...

In this study, the properties and adsorption behaviors of organoclays synthesized with two structurally different surfactants having same carbon chain length (hexadecyltrimethylammonium bromide (HDTMAB) benzyldimethylhexadecylammonium chloride (BDHAC)) were evaluated. The structural examined using Fourier-transform infrared spectroscopy, zeta potential analysis, X-ray diffraction, N2 adsorption...

We report the detection of heterogeneities in the diffusion of lipid molecules for the three-component mixture dipalmitoyl-PC/dilauroyl-PC/cholesterol, a chemically simple lipid model for the mammalian plasma membrane outer leaflet. Two-color fluorescence correlation spectroscopy (FCS) was performed on giant unilamellar vesicles (GUVs) using fluorescent probes that have differential lipid phase...

The biosorption of three reactive azo dyes (red, black and orange II) found in textile effluents by inactive mycelium of Cunninghamella elegans has been investigated. It was found that after 120 hours of contact the adsorption led to 70%, 85%, 93% and 88% removal of reactive orange II, reactive black, reactive red and a mixture of them, respectively. The mycelium surface was found to be selecti...

Binary mixtures of organic solvents with limited miscibility are investigated by a two parameter equation which reliably describes the polarity of mixtures as a function of their composition. A relation is found between limited miscibility and critical change of solvent structure. The polarity of liquid mixtures of organic solvents has been quantitatively investigated in preceding papers I-6). ...
