The spinel has been prepared at low temperature using a new sol‐gel process. X‐ray diffraction analysis reveals that the obtained material presents cubic structure with unit cell parameter lower than of stoichiometric . photoelectron spectroscopy confirms divalent state doped nickel in material. Furthermore, compound can intercalate second lithium both chemically and electrochemically, leading to formation same structure. This only one plateau around 3 V vs. large discharge capacity 160...

We have performed molecular dynamics calculations of liquid carbon disulfide and benzene, intending to examine the effect pressure on far-infrared collision-induced absorption as well local structure reorientational dynamics. The reproduced experimental results correlation times at pressures, anisotropy density dependence dipole moments their time derivatives both liquids.

Uncertainty evaluations for kinematic viscosity measurements using a series of capillary master viscometers are given, based on model equations considering precise corrections the U-tube-type used at National Metrology Institute Japan (NMIJ). Results viscometer constant calibrations NMIJ scale calibrated by stepping up to high viscosities, and standard liquids with temperatures from −40 °C 100 °C, evaluated in detail. The relative expanded uncertainties k = 2 0.04% 0.17% range 160 000 mm2 s−1.
We present that the tractional flow of a lubricant shows three kinds limiting shear stresses at which take place independently rates in its viscous, viscoelastic, and glassy states. propose models on mechanisms for stresses, based data Brillouin spectra viscosity viscoelastic liquids previously reported by us deformation polymers referred from others.

The far-infrared optical constants of liquid acetonitrile, carbon disulfide, and tetrachloride were determined from transmission measurements with a synchrotron radiation source at the Institute for Molecular Science (Okazaki). small size was benefit to transmittances that suited an analysis based on theory. From acetonitrile temperatures ranging 238 343 K, both absorption coefficients refractive indices obtained by using subtractive Kramers–Kronig relation proposed Jones co-workers. dipole...
The Brillouin spectra of di(2-ethylhexyl) sebacate, which is a liquid lubricant known as DOS, were measured at up to 5 GPa 25 °C and 2.5 80 °C. At °C, the frequency linewidth (acoustic attenuation) has large maximum 0.1 MPa, it broad 0.8 GPa. shift (sound velocity) obtained indicate that dispersion sound velocities DOS occurs from MPa origins this attenuation are discussed on basis theory for viscoelastic liquid. It proposed acoustic due production higher-rank structures with nano-order...
In this paper, a new high-pressure viscosity measurement system using capillary method is reported. system, two pressure balances are used to generate stable and flow field in the capillary. The volumetric rate was measured by calculating change piston fall rate. To check effectiveness of method, bis(2-ethylhexyl) sebacate at pressures up 200 MPa. Differential had linear relationship all temperature conditions, indicating that Hagen–Poiseuille law can be applied method. viscosity–pressure...
This paper proposes a hybrid-type system for microvibration isolation. The hybrid is composed of passive spring-damper which reduces vibrations high-frequency area and an active one those low-frequency area.

Gamow‐Teller (GT) transitions can be studied in both β‐decay and charge exchange(CE) reactions. If isospin is a good quantum number, then the Tz = −1→0 +1→0 GT mirror transitions, are identical. Therefore, comparison of results from studies β decay CE should shed light on this assumption. Accordingly we have −1 fp‐shell nuclei, 54Ni, 50Fe, 46Cr, 42Ti, produced fragmentation compared our with spectra (3He, t) measurements +1 target nuclei high resolution at RCNP, Osaka.
