Re-construction layer effect of LiNi0.8Co0.15Mn0.05O2 with solvent evaporation process

Re-construction layer effect of LiNi0.8Co0.15Mn0.05O2 with solvent evaporation process

The solvent evaporation method on the structural changes and surface chemistry of the cathode and the effect of electrochemical performance of Li1.0Ni0.8Co0.15Mn0.05O2 (NCM) has been investigated. After dissolving of Li residuals using minimum content of solvent in order to minimize the damage of pristine material and the evaporation time, the solvent was evaporated without filtering and remain...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Porous Fiber Formation in Polymer-Solvent System Undergoing Solvent Evaporation

The Effect of Some Processing Conditions on the Characteristics of Biodegradable Microspheres Obtained by an Emulsion Solvent Evaporation Process

Unloaded microspheres were prepared from polyhydroxybutyrate (PHB) and polyhydroxybutyrateco-valerate (PHB-HV) polymers using an oil-in-water emulsion solvent evaporation method. The study was conducted to evaluate how the polymer and some process parameters affect properties of the final microspheres such as particle size, superficial area, zeta potential, surface morphology and microsphere de...

Structuring of polymer solutions upon solvent evaporation.

The morphology of solution-cast, phase-separated polymers becomes finer with increasing solvent evaporation rate. We address this observation theoretically for a model polymer where demixing is induced by steady solvent evaporation. In contrast to what is the case for a classical, thermal quench involving immiscible blends, the spinodal instability initially develops slowly and the associated l...
