Adv Colloid Interface Sci 2022 Jul 16;305:102697. Epub 2022 May 16.

School of Chemical Engineering, The University of Queensland, St Lucia, Brisbane, QLD 4072, Australia. Electronic address:

Sulphidisation, an electrochemical process for conversion of a non-sulphide, oxide or oxidised sulphide, to a sulphide surface that facilitates efficient adsorption of thiol collectors to impart hydrophobicity, offers a way to improve the enrichment of oxide and oxidised sulphide ores by flotation. Although it has shown great potential, it has equally proved to suffer from drawbacks such as low efficiency, difficulty to sulphidise minerals that are prone to surface oxidation and the chemistry at play remains insufficiently understood. These drawbacks hinder the full potential of the sulphidisation process as a remediation strategy for flotation of oxide and oxidised sulphide ores. Read More

Manipulating the morphology of colloidal particles via ion beam irradiation: A route to anisotropic shaping.

Adv Colloid Interface Sci 2022 Jun 11;304:102642. Epub 2022 Mar 11.

Laboratory of Biosensors and Bioelectronics, Institute for Biomedical Engineering, ETH Zurich, Gloriastrasse 35, 8092 Zurich, Switzerland. Electronic address:

Ion beam irradiation of spherical colloidal particles is a viable route to induce particle deformation, especially to get anisotropic shapes. Even though less common in comparison with dry etching techniques, different types of morphological changes can be attained depending on the process parameters (angle of incidence, energy, fluence of the ion beam, type of ion, temperature) and on particle material and initial particle arrangement (crystalline or disordered, made up of isolated or closely-packed particles). The technique can be harnessed to get anisotropic deformation of spherical colloidal particles into an ellipsoidal shape, but also to tailor the interstices between closely-packed colloidal particles, to get particle necking and coalescence as well as particle rearrangement.

In recent decades, due to the increase in awareness, most consumers prefer foods that not only satisfy their primal urge of hunger but also include health-promoting effects on the body. Therefore, the food industry has an increasing tendency to apply the nutrients (like vitamins, essential fatty acids and minerals) and replace synthetic additives with natural bioactives (like phenolics and essential oils) to produce functional products. However, low dispersibility and shelf-stability as well as presenting unpleasant taste and odor are the most critical barriers for direct incorporation of these useful compounds into foods.

Capillary imbibition and flow of wetting liquid in irregular capillaries: A 100-year review.

Adv Colloid Interface Sci 2022 Jun 29;304:102654. Epub 2022 Mar 29.

State Key Laboratory of Petroleum Resources and Prospecting, China University of Petroleum, Beijing 102249, PR China. Electronic address:

Capillary imbibition, such as plant roots taking up water, reservoir rocks absorbing brine and a tissue paper wiping stains, is pervasive occurred in nature, engineering and industrial fields, as well as in our daily life. This phenomenon is earliest modeled through the process that wetting liquid is spontaneously propelled by capillary pressure into regular geometry models. Recent studies have attracted more attention on capillary-driven flow models within more complex geometries of the channel, since a detailed understanding of capillary imbibition dynamics within irregular geometry models necessitates the fundamentals to fluid transport mechanisms in porous media with complex pore topologies.
