Towards sustainable processing of columbite group minerals: Elucidating the relation between dielectric properties and physico-chemical transformations in the mineral phase (2017)
Journal Article

© 2017 The Author(s). Current methodologies for the extraction of tantalum and niobium pose a serious threat to human beings and the environment due to the use of hydrofluoric acid (HF). Niobium and tantalum metal powders and pentoxides are widely us...

Selective molecular annealing: in situ small angle X-ray scattering study of microwave-assisted annealing of block copolymers (2017)
Journal Article

Microwave annealing has emerged as an alternative to traditional thermal annealing approaches for optimising block copolymer self-assembly. A novel sample environment enabling small angle X-ray scattering to be performed in situ during microwave anne...

Calibrated X-ray micro-tomography for mineral ore quantification (2017)
Journal Article

Scanning Electron Microscopy (SEM) based assessments are the most widely used and trusted imaging technique for mineral ore quantification. X-ray micro tomography (XMT) is a more recent addition to the mineralogy toolbox, but with the potential to ex... Read More about Calibrated X-ray micro-tomography for mineral ore quantification.

Towards large scale microwave treatment of ores: Part 1 – Basis of design, construction and commissioning (2017)
Journal Article

Despite over thirty years of work, microwave pre-treatment processes for beneficiation of ores have not progressed much further than laboratory testing. In this paper we present a scaleable pilot-scale system for the microwave treatment of ores capab...

Metal-organic frameworks in seconds via selective microwave heating (2017)
Journal Article

© The Royal Society of Chemistry. Synthesis of metal-organic framework (MOF) materials via microwave heating often involves shorter reaction times and offers enhanced control of particle size compared to conventional heating. However, there is little... Read More about Metal-organic frameworks in seconds via selective microwave heating.

New insights into the role of selective and volumetric heating during microwave extraction: investigation of the extraction of polyphenolic compounds from sea buckthorn leaves using microwave-assisted extraction and conventional solvent extraction (2017)
Journal Article

We report a direct comparison of microwave heating and conventional heating in solvent extraction by using exactly the same reaction conditions (including heating rate) in the extraction of polyphenols from dried sea buckthorn leaves. We have for the...

Statistical description of inhomogeneous samples by scanning microwave microscopy (2017)
Journal Article

A quantitative analysis of the dielectric properties of a multiphase sample using a scanning microwave microscope (SMM) is proposed. The method is demonstrated using inhomogeneous samples composed of a resin containing micrometric inclusions of a kno...
