Nucleation kinetics of lithium phosphate precipitation

Abstract

Lithium phosphate is an important material today in battery technology and catalysis, the source of which is gradually depleting. In this work we provide insights into the kinetics of lithium...

Non-equilibrium Composition of Mixed Metal Hydroxide Membranes Grown in Flow Systems

“…The resulting formation of a semi-permeable membrane around the dissolving seed initiates the development of a steep chemical gradient, which drives, by a combination of osmotic pressure and buoyant forces, the growth of hollow structures . These structures mimic hydrothermal vent chimneys in terms of their shapes and chemical gradients but more importantly also in terms of the product materials and porosities. − Starting from these chemical gardens, recent work has greatly increased the reproducibility and spectroscopic accessibility by introducing spatial confinement to quasi-two-dimensional Hele–Shaw cells − and microfluidic channels. − The latter approach allows for the creation of two co-flowing reactant streams that nucleate and sustain the growth of a linear precipitation membrane at their reactive interface.…”
