This study presents the first account of the near-infrared (NIR) spectra of the alkali carbonates: [Cs2CO3] [Rb2CO3] [K2CO3] [Na2CO3] and [Li2CO3]. Seven NIR bands (labelled [A] to [G] inclusive) within the [4000-6000cm-1] (2.5-1.66μm) region of int

The near-infrared (NIR) spectra of powdered carbonate minerals is of significant multidisciplinary interest. However, there is a paucity of accounts of the behaviour of NIR bands as a function of particle size in well-constrained experimental setting

Plastics and synthetic materials are polluting the world's oceans. In this study we exposed juvenile mussels, Mytilus edulis, to glass reinforced plastic (GRP) dust, under laboratory conditions. The study ran for a period of 7 days, to test for the m

Objective Uncontrolled rapid release of drugs can reduce their therapeutic efficacy and cause undesirable toxicity; however, controlled release from reservoir materials helps overcome this issue. The aims of this study were to determine the release p
