Milled B-doped mesophase pitch-based carbon fibers (mMPCF's) prepared from a melt-blown petroleum pitch precursor material have been developed for enhanced Li uptake capacity in ion batteries. Raman spectroscopy has used to investigate the structure of graphitized and mMPCF's using 632.8-nm HeNe laser excitation. The show strong peak near $1330{\mathrm{cm}}^{\ensuremath{-}1},$ well-defined at $1620{\mathrm{cm}}^{\ensuremath{-}1},$ disappearance second-order...
The regulation of calcite mineralization by chiral biological molecules is one the fundamental unresolved issues at interface between biological, geological, and physical sciences. Here we address role chirality l-aspartic acid (l-Asp), a model additive, in growth crystals. We apply phase-shift interferometry to nonintrusively monitor in-situ morphology surface quantify velocity propagation edges unfinished crystal layers, steps, during crystallization. show that l-Asp leads several-fold...
Mesophase pitch-based carbon fibers (MPCFs) have recently been developed for use as high performance anode materials in Li ion secondary batteries, having a microscopic well macroscopic structure especially suitable storage. Because of the highly anisotropic diamagnetic moment observed between 50 and 310 K pristine milled MPCF segments, they can easily be oriented parallel to an applied magnetic field, by scanning electron microscopy. A simple model is proposed explain both alignment undoped...
Elucidating reaction inhomogeneity of composite electrodes is key to improve the performances batteries such as rate capability and durability. Because often disappears after a certain relaxation period, operando analytical techniques are indispensable. We hereby propose that optical analysis common lab method can be applied visualize LiFePO4 for lithium-ion with sufficient space time resolutions. The results indicate brightness charged phase was higher than discharged phases, which used...
RM2 (R = rare earth, M Al, Ni and Co) compounds have large entropy change magnetic transition temperatures can be controlled by of R and/or so that are suitable to a refrigerator for hydrogen liquefaction under development. In order improve performance, spherical powdered HoAl2, DyAl2, GdNi2 with submillimeter diameter were synthesized centrifugal atomization process. By measuring the magnetization heat capacity, we obtained fields as functions temperature field, which essential analysing...
Polyethylene glycol (PEG) is transparent in the liquid phase and turns to a translucent solid through transition at around room temperature. A PEG solution of rhodamine 6G was excited by laser pulse (527 nm wavelength, 10 ns duration, 190 μJ) measure fluorescence spectra during process. Whereas peak weak broad 60 °C (spontaneous emission), strong, narrow appeared temperature range below 50 °C, since stimulated emission (amplified spontaneous emission) took place due scattering PEG. This...
MnBi thin films have been studied as a magneto-optical memory element. Ordinarily, restricted conditions are required for preparing pure film with excellent properties and homogeneity. However, in the case of Mn-Bi-Te films, it was found that adopting proper composition made easy to prepare homogeneous figure merit F/α not worse than reported by other authors. Furthermore, Faraday rotation controlable varying Mn-Bi-Te. Then, magnetic holograms were formed using exhibiting magnetization...
Polyethylene-glycol (PEG) exhibited bistable transmission characteristics (transparent or opaque) in heating (melting) and cooling (freezing) processes. The temperature range depended on the molecular weight extended when different types of PEGs were mixed. For example, with weights 300 2000 mixed, bistability took place 2–38 °C range. This phenomenon was used to fabricate a optical fiber switch which mixed PEG put gap between ends two polymer fibers. property demonstrated by controlling...
