Ni-rich LiNi1-xCoxMnyO2 (x ≥ 0.8) cathode is regarded as promising cathode for high-energy lithium ion batteries. One important challenge for Ni-rich LiNi1-xCoxMnyO2 is to enhance the long-term stability with maintain high energy density.

Rapid Communications in Mass Spectrometry, 2019
RATIONALE Field measurement of denitrification in agricultural ecosystems using the 15 N gas flux method has been limited by poor sensitivity because current isotope ratio mass spectrometry is not precise enough to detect low 15 N2 fluxes in the presence

Stability of the Active Flux Method in the Framework of Summation-by-Parts Operators
arXiv.orgThe Active Flux method is a numerical method for conservation laws using a combination of cell averages and point values, based on ideas from finite volumes and finite differences. This unusual mix has been shown to work well in many situations.

Laminar burning velocities were measured by the heat flux method for premixed methane dimethyl-ether mixtures (CH4/DME) with air, at various mixture fractions from 100% CH4 to 100% DME with hydrogen addition of 0%, 20% and 40%.

Reduced DC-link capacitance permanent magnet synchronous motor (PMSM) drives have many advantages, such as longer lifetime, reduced cost and higher power density. However, due to the DC-link voltage fluctuation, the DC-link voltage utilization rate and the torque ripples are two major issues in flux-weakening operation region.

On Flux-Difference Residual Distribution Methods
Bulletin of the Malaysian Mathematical Sciences Society, 2017It is well known that residual distribution methods are less sensitive to mesh variations, in contrast to finite volume methods. However, in most cases, most of the residual distribution methods are just first order accurate in space for unsteady calculations while the same methods are higher order accurate for the corresponding steady-state problems ...

Flux separation methods for flux-grown single crystals
Philosophical Magazine, 2012After the growth of crystals an important step is their separation from the flux. Here the temperature of separation, the mechanical robustness and the chemical reactivity of the crystals constitute the basic conditions which have to be respected by the method. In this contribution several different techniques of flux separation at the end of a crystal
