In a smart solution-processable luminescent poly(norbornene)/oxazine-1 (Ox1) intercalated fluoromica nanohybrid, the supramolecular organization of the Ox1 dyes can be tuned at the nanoscale level and a deep red emission band switched on by inducing a phase segregation of aligned molecules within the fluoromica layered scaffold. By combining low-temperature photoluminescence and ultrafast pump-...

A unique example of an ESIPT coupled AIEE process, associated with a single molecule (1), is utilized for generating multiple luminescent colors (blue-green-white-yellow). The J-aggregated state of 1 forms a luminescent gel in THF and this luminescent property is retained even in the solid state.

We synthesized the uniform core-shell microstructured compounds with hexagonal phase NaYF₄:Er/Yb microrods as the core and hexagonal phase NaLnF₄ (NaYbF₄, NaLuF₄:Yb/Tm, NaYF₄:Yb/Er, NaYF₄:Eu) as the shell based on the hydrothermal reaction. These microscale core-shell structures provided a platform for the spatially confining optical process while possessing high luminescence efficiency. The th...

In this study, we introduce a wide spectral range (200-2500 nm) imaging system with a 250 μm minimum spatial resolution, which can be freely modified for a wide range of resolutions and measurement geometries. The system has been tested for reflectance and luminescence measurements, but can also be customized for transmittance measurements. This study includes the performance results of the dev...

This paper reports on efforts to enhance the photovoltaic performance of textured silicon solar cells through the application of a layer of Eu-doped silicate phosphor with particles of various dimensions using the spin-on film technique. We examined the surface profile and dimensions of the Eu-doped phosphors in the silicate layer using optical microscopy with J-image software. Optical reflecta...

The results of the development a small-sized laser fiber fluorimeter in IR spectral range for luminescent photodiagnostics superficial localization tumors are presented. This device, working conjunction with “Fluroscan” type pharmaceutical composition based on 2,4-di(α-methoxyethyl)deuteroporphyrin IX ytterbium complex dipotassium salt, ensures achievement high values diagnostic contrast index ...

Metal-organic frameworks (MOFs) are a unique class of crystalline solids comprised of metal cations (or metal clusters) and organic ligands that have shown promise for a wide variety of applications. Over the past 15 years, research and development of these materials have become one of the most intensely and extensively pursued areas. A very interesting and well-investigated topic is their opti...

Biologics manufacturing requires the clearance of Host Cell Proteins (HCPs) from recombinant therapeutic protein to acceptable low levels to ensure product purity and patient safety. To ensure adequate removal, a highly sensitive method, commonly in the form of Enzyme-Linked Immunosorbent Assay (ELISA), is necessary to quantify the HCPs amount in process intermediates and drug substance. We rep...

Suppression subtractive hybridization (SSH) was employed to investigate bioluminescence in Panellus stipticus (Bull.) P. Karst. by detecting proteins differentially expressed in bioluminescent and luminescent strains. Comparisons of luminescent and non-luminescent monokaryon cultures of North American strains revealed differences in transcript levels of proteins responsible for post-translation...

background: since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. we performed an analytical evaluation of the new electrochemiluminescent immunoassay (eclia) for serum tsh, ft4 and t3 in the elecsys 2010 immunoassay system and compared the resu...
