Makkad, Sarabjot Kaur published the artcileπ-Conjugated Chromophore Incorporated Polystyrene Nanobeads as Single Optical Agent for Three-Channel Fluorescent Probe in Bioimaging Application, Synthetic Route of 146370-51-6, the publication is ACS Biomaterials Science & Engineering (2017), 3(8), 1788-1798, database is CAplus and MEDLINE.

Fluorescent polystyrene (PS) nanobeads in the size range ∼70-120 nm incorporating perylene bisimide (PBI-PS) and/or oligo(p-phenylenevinylene) (OPV-PS) were developed by the miniemulsion polymerization technique. A dye loading content (DLC) of <3% was sufficient to impart high fluorescence emission capability to the PS beads. OPV-PS exhibited emission in the range 400-550 nm with peak emission at 450 nm (λ_ex = 350 nm; φ_FL = 26%); PBI-PS showed emission from 520-650 nm with peak emission at 545 nm (λ_ex = 490 nm; φ_FL = 9.7%) in 1× PBS buffer, whereas OPV(PBI)-PS nanobeads incorporating both the fluorophores exhibited multicolor emission capabilities (λ_ex from 350 to 490 nm). The nanoparticles were characterized by field-emission SEM (FESEM), TEM and dynamic light scattering (DLS) for size and zeta potential for surface charge. For bioimaging applications, the PS nanoparticles were incubated with HeLa cells. Cell viability anal. involving HeLa cells showed >90% cell viability confirming the biocompatibility of the PS beads. The cellular uptake of the nanoparticles was confirmed by flow cytometry anal. and confocal laser scanning microscopy (CLSM) images. The subcellular localization of the nanoparticles in the cytoplasm could be precisely established by their simultaneous multicolor emission. The PS-based single optical agent presented here that can function as three-channel fluorescent probe to meet the requirements for multicolor bioimaging is advantageous.

Shankar, Jaya Seeli published the artcileStudies on Optical Characteristics of Multicolor Emitting MEH-PPV/ZnO Hybrid Nanocomposite, Formula: C15H24O2, the publication is Polymer-Plastics Technology and Materials (2019), 58(2), 148-157, database is CAplus.

The present work endeavors towards the scientific study on influence of ZnO nanoparticles on the optical characteristics of Poly [2 Methoxy (5, 2′ Ethylhexyloxy)-P-Phenylenevinylene] (MEH-PPV), a light emitting polymer. Hybrid nanocomposites of MEH-PPV were prepared by dispersing ZnO nanorods at loading concentrations of 1 weight % and 3 weight %. The structural characteristics of the hybrid composites were investigated using FTIR spectroscopy and X-ray diffraction. The UV absorption spectra and Photoluminescence emission spectra were analyzed in order to study the optical characteristics of nanocomposite. The optical constants were determined and the suitability of the composites for light emission was analyzed. The incorporation of ZnO nanorods facilitates the shift in emission wavelength and witnesses the color tuning ability and multicolor emission from the composite.

De Giorgio, Francesca published the artcileDeciphering the Interplay between Binders and Electrolytes on the Performance of Li4Ti5O12 Electrodes for Li-Ion Batteries, HPLC of Formula: 143-24-8, the main research area is binder electrolyte lithium titanium oxide electrode battery.

Lithium titanium oxide (Li4Ti5O12, LTO) is an attractive neg. electrode for the development of safe-next-generation-lithium-ion batteries (LIBs). LTO can find specific applications complementary to existing alternatives for LIBs thanks to its good rate capability at high C-rates, fast lithium intercalation, and high cycling stability. Furthermore, LIBs featuring LTO electrodes are inherently safer owing to the LTO’s operating potential of 1.55 V vs. Li+/Li where the commonly used organic-based electrolytes are thermodynamically stable. Herein, we report the combined use of water-soluble sodium alginate (SA) binder and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI)-tetraglyme (1m-T) electrolyte and we demonstrate the improvement of the electrochem. performance of LTO-based electrodes with respect to those operating in conventional electrolyte 1M LiPF6-ethylene carbonate: di-Me carbonate (LP30). We also tackle the anal. of the impact of combining the binder/electrolyte on the long-term cycling performance of LTO electrodes featuring SA or conventional polyvinylidene fluoride (PVdF) as binders. Therefore, to assess the impact of the combination of binder/electrolyte on performance, we performed post-mortem characterization by ex situ synchrotron diffraction experiments of LTO electrodes after cycling in LP30 and 1m-T electrolytes.

Zivkovic, Nikola V. published the artcileVolumetric and Viscometric Study of 1-Hexanol-Based Binary Systems: Experimental Determination and Modeling, Name: 2,5,8,11,14-Pentaoxapentadecane, the main research area is volumetric viscometric hexanol based binary system model.

D., viscosity, and refractive index of four binary mixtures with 1-hexanol are exptl. determined at seven temperatures, at from 288.15 to 318.15 K and at atm. pressure. The choice of mixtures was based on their potential for applications in flue gas cleaning processes. From exptl. data, excess molar volume, viscosity deviation, excess molar Gibbs free energy of activation of viscous flow, deviation in refractive index, and partial and excess partial molar volumes are calculated, correlated with the Redlich-Kister equation, and used for better understanding of mol. interactions between the mixture components. Since the mixtures were investigated both from the theor. point of view and with the aspect for practical applications, modeling of two key properties, viscosity and excess molar volume, was performed with different models and approaches and the results are compared with exptl. values.

Gonzalez, Juan A. published the artcileVolumetric and Viscosimetric Measurements for Methanol + CH3-O-(CH2CH2O)n-CH3 (n = 2, 3, 4) Mixtures at (293.15-303.15) K and Atmospheric Pressure: Application of the ERAS Model, COA of Formula: C10H22O5, the main research area is methanol trioxanonane tetraoxadodecane pentaoxapentadecane thermophys property.

Abstract: Densities, ρ, and kinematic viscosities, ν, have been determined at atm. pressure and at 293.15-303.15 K for binary mixtures formed by methanol and one linear polyether of the type CH3-O-(CH2CH2O)n-CH3 (n = 2, 3, 4). Measurements on ρ and ν were carried out, resp., using an Anton Paar DMA 602 vibrating-tube densimeter and an Ubbelohde viscosimeter. The ρ values were used to compute excess molar volumes, VEm, and, together with the ν results, dynamic viscosities (η). Deviations from linear dependence on mole fraction for viscosity, Δη, are also provided. Different semi-empirical equations have been employed to correlate viscosity data. Particularly, the equations used are the: Grunberg-Nissan, Hind, Frenkel, Katti-Chaudhri, McAllister and Heric. Calculations show that better results are obtained from the Hind equation. The VEm values are large and neg. and contrast with the pos. excess molar enthalpies, HEm, available in the literature, for these systems. Methanol + CH3-O-(CH2CH2O)n-CH3 mixtures have been treated in the framework of the ERAS model. Results for HEm are acceptable, while the composition dependence of the VEm curves is poorly represented. This has been ascribed to the existence of strong dipolar and structural effects in the present solutions

This paper presents the d. of selected glymes (monoglyme, diglyme, triglyme and tetraglyme) in N,N-dimethylformamide + water mixtures at four temperatures: 293.15 K, 298.15 K, 303.15 K and 308.15 K. The d. data were used to calculate the apparent molar volumes (VΦ,m) and limiting apparent molar volumes (V0Φ,m = V0m), as well as the limiting molar expansion volume coefficient E0p,m. Changes in the obtained values of the physicochem. parameters, as functions of composition and temperature, were analyzed in terms of the mol. interactions and structural differentiation of the investigated systems. The process of hydrophobic hydration of the studied glymes is visible in the area of high water content in the mixture

Jankowski, Piotr published the artcileStructure of Magnesium Chloride Complexes in Ethereal Systems: Computational Comparison of THF and Glymes as Solvents for Magnesium Battery Electrolytes, COA of Formula: C10H22O5, the main research area is magnesium chloride THF electrolyte electron transfer anion glyme.

The structure of the electrolyte is crucial for the performance of rechargeable magnesium batteries. Doubly charged cations interact much stronger with both anions and solvent mols., forming different size clusters. Here, we apply DFT calculations to investigate salt solvation by altering the first solvation shell of the magnesium-chloride complexes in different ethereal solvents: THF, monoglyme, diglyme, triglyme and tetraglyme. The anal. was performed by looking for the most stable structures, considering mono-, di- and trimeric clusters of MgxCly. The determination of clusters geometries, together with their energies, resulted in a comprehensive picture of the thermodynamically preferred state of the electrolyte, and allowed for a simple assessment of the electrochem. activity of the electrolyte. Our anal. shows that clustering is beneficial for desolvation of magnesium from the cluster, but causes overpotentials due to hindered electron transfer.

Li, Jiaxin published the artcileLi-CO2 Batteries Efficiently Working at Ultra-Low Temperatures, Synthetic Route of 143-24-8, the main research area is low temperature lithium carbon dioxide battery.

Lithium-carbon dioxide (Li-CO2) batteries are considered promising energy-storage systems in extreme environments with ultra-high CO2 concentrations, such as Mars with 96% CO2 in the atm., due to their potentially high specific energy densities. However, besides having ultra-high CO2 concentration, another vital but seemingly overlooked fact lies in that Mars is an extremely cold planet with an average temperature of approx. -60°C. The existing Li-CO2 batteries could work at room temperature or higher, but they will face severe performance degradation or even a complete failure once the ambient temperature falls below 0°C. Herein, ultra-low-temperature Li-CO2 batteries are demonstrated by designing 1,3-dioxolane-based electrolyte and iridium-based cathode, which show both a high deep discharge capacity of 8976 mAh g-1 and a long lifespan of 150 cycles (1500 h) with a fixed 500 mAh g-1 capacity per cycle at -60°C. The easy-to-decompose discharge products in small size on the cathode and the suppressed parasitic reactions both in the electrolyte and on the Li anode at low temperatures together contribute to the above high electrochem. performances.
