Charge Transfer-Type Fluorescence of Ti-doped Ca14Al10Zn6O35
2016 / Journal of LuminescenceThe calcium aluminum zincates Ca14(Al1-2xTixZnx)10Zn6O35, in which Al3+ sites in the host material Ca14Al10Zn6O35 are simultaneously substituted by Ti4+ and Zn2+, were synthesized by a polymerized complex method. Al3+ ions could be replaced up to an xvalue of 0.1. The host material does not exhibit fluorescence, while the cation-substituted samples show an emission...

Improved Doxorubicin Encapsulation and Pharmacokinetics of Ferritin−Fusion Protein Nanocarriers Bearing Proline, Serine, and Alanine Elements
2016 / BiomacromoleculesA novel human ferritin-based nanocarrier, composed of 24 modified monomers able to auto-assemble into a modified protein cage, was produced and used as selective carrier of anti-tumor payloads. Each modified monomer derives from the genetic fusion of two distinct modules, namely the heavy chain of human ferritin (HFt) and a stabilizing/protective PAS polypeptide se...

Enhanced luminescent properties of Ca3−xTbxZrSi2O9+x/2 phosphors by Al3+ doping into the Zr4+ site in the host lattice
2014 / Journal of LuminescenceGreen-emitting Ca3−xTbxZr1−yAlySi2O9+(x–y)/2 (0.05≤x≤0.20, 0≤y≤0.07) phosphors were synthesized in a single phase form by the conventional solid-state reaction method and their photoluminescent properties were investigated. These phosphors exhibited typical emission peaks assigned to the transition from 5D4 to 7FJ (J=3, 4, 5, and 6) of...

Dosimeter properties of Ce and Eu doped LiCaAlF6
2014 / Radiation MeasurementsOptical, scintillation properties, optical stimulated luminescence, and thermally stimulated luminescence of Ce 1, 3, and 5% doped and Eu 1, 1.5, and 2% doped LiCaAlF6 crystals fabricated by Tokuyama Corp. were investigated. In transmittance, absorption was proportional to dopant concentrations and typical optical quantum yield of Ce and Eu-doped LiCaAlF6 were 40 a...

Polystyrene grafted carbon black synthesis via in situ solution radical polymerization in ionic liquid
2013 / Journal of Polymer ResearchDENKA BLACK/polystyrene nanocomposites (DB/PS) were successfully prepared through a facile strategy. Some of the styrene molecules were grafted and polymerized onto the surface of the DB via the in situ free radical addition process in ionic liquid, and others self-polymerized and coated on the polystyrene grafted DB. The ionic liquid improves the grafting percenta...

Raman Analysis of Injection Molding -measurement of the polymer state during a process
/ JASCO Corp.In this brief application Raman analysis of injection molding was made using the RMP-210 a ‘field-rugged’ Raman Spectrometer consisting of a probe head and monochromator, which are connected by optical fibers. Since the system does not require external cooling, it is portable and allows measurements in almost any location. The probe head is extremely fl...

Optical Evaluation of Write Spots in a CD-R by Transmittance Measurement
/ JASCO Corp.Crystal anisotropy of materials, optical rotatory power, and dynamics under a magnetic field are known to affect polarization of transmitted light through certain materials. In practical applications, they are used for high-density recording and display devices. Combining a polarization maintaining fiber probe and the transmission option of the JASCO Near-Field Sys...

Evaluation of Micro Optics
/ JASCO Corp.The MSV-300 series is a microspectroscopy system providing transmittance and reflectance measurements of microscopic sample sites for a wide range of wavelengths from the ultraviolet to the near infrared. Conventional measurements require samples with dimensions comparable to a millimeter-sized optical beam. The MSV-300 series can provide measurements of the color,...

Green-emitting (La,M,Tb)OCl (M = Mg, Ca, and Sr) phosphors
2012 / Optical MaterialsGreen-emitting (La1−x−yMxTby)OCl (0 ⩽ x ⩽ 0.13, 0.03 ⩽ y ⩽ 0.15, M = Mg, Ca, and Sr) single phase phosphors were synthesized using a liquid-phase method and their photoluminescence properties were characterized. The excitation spectrum consisted of a strong broad band from 220 to 290 nm, which corresponds to the 4f–5d transition of Tb3+. The oxych...

First enantioseparation and circular dichroism spectra of Au38 clusters protected by achiral ligands
2012 / Nature CommunicationsBestowing chirality to metals is central in fields such as heterogeneous catalysis and modern optics. Although the bulk phase of metals is symmetric, their surfaces can become chiral through adsorption of molecules. Interestingly, even achiral molecules can lead to locally chiral, though globally racemic, surfaces. A similar situation can be obtained for metal part...

Interactions of gemini surfactants with two model proteins: NMR, CD, and fluorescence spectroscopies
2012 / Journal of Colloid and Interface ScienceGemini surfactants have two polar head groups and two hydrocarbon tails. Compared with conventional surfactants, geminis have much lower (μM vs. mM) critical micelle concentrations and possess slower (ms vs. μs) monomer ⇆ micelle kinetics. The structure of the gemini surfactants studied is [HOCH2CH2–, CH3–, CH3(CH2)15–N+–(CH2)s–N...

Charged polaron-enhanced circular dichroism of optically nonlinear 3-nitroaniline crystal
2011 / Optical MaterialsThe circular dichroism (CD) spectra in visible range of the 3-nitroaniline (m-NA) single crystal, of its solution in chloroform, and in the KBr pellet were recorded. Neither the molecular (m or Cs) nor the crystal (mm2 or C2v) point groups belong to the chiral groups. The DFT calculation of CD spectrum of the m-NA isolated neutral molecule confirmed its chirality. ...
