This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...

Water-fat separation techniques play an important role in a variety of clinical and research applications. In particular, multiecho separation methods remain a topic of great interest due to their ability to resolve water and fat images in the presence of B(0)-field inhomogeneity. However, these methods are inherently slow as they require multiple measurements. An accelerated technique with red...

In this article, the ternary phase diagram in polyamide-6 (PA6)/Formic acid (FA)/Water system was constructed by experimental measurement. The determination of binodal curve was measured according to titration of the PA6 polymer solution with water as a non-solvent until the onset of turbidity. Also, the phase separation process of the prepared membranes structures system was investigated. The ...

Whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. In this study, selective separation of whey components by Aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. It has been shown that it is possible to recover valuable components of w...

Here we present a new strategy of selectively rejecting water vapor while allowing fast transport of dry gases using temperature-controlled aligned-multiwalled carbon nanotubes (aligned-MWNTs). The mechanism is based on the water vapor condensation at the entry region of nanotubes followed by removing aggregated water droplets at the tip of the superhydrophobic aligned-MWNTs. The first condensa...

Interfacial adhesion between graphene and various substrate materials is essential for practical applications of graphene. To date, most of the studies on adhesion of graphene have assumed dry adhesion of van der Waals type. In this paper, we conduct molecular dynamics simulations to study the traction–separation behaviors for wet adhesion of graphene on amorphous silicon oxide covered by a thi...

Membranes that separate oil-water mixtures based on contrasting wetting properties have recently received significant attention. Separation of nanoemulsions, i.e. oil-water mixtures containing sub-micron droplets, still remains a key challenge. Tradeoffs between geometric constraints, high breakthrough pressure for selectivity, high flux, and mechanical durability make it challenging to design ...
