Antibiotics are used not only to fight infections and inhibit bacterial growth, but also as growth promotants in farm livestock. Farm runoff and other farm-linked waste have led to increased antibiotic levels present in the environment, the impact of which is not completely understood. Soil, more specifically clays, that the antibiotic contacts may alter its effectiveness against bacteria. In this...
This paper aims at evaluating the inhibition performance of dopamine (DA) on hydrated swelling of montmorillonite (MMT) and exploring the inhibitive mechanism. The inhibition performance of DA was evaluated through the combination of linear swelling and mud making tests, and compared with three commonly used inhibitors in the field. The results show that DA performs extremely well on inhibiting the...
The inhibition of hydration and dispersion of drilling cuttings and maintaining of proper flow properties of drilling fluids play a significant role in a successful drilling process. In this work, we show that low molecular weight polyetheramine provides sufficient inhibiting performance while it has no effect on the rheological properties of clay dispersions. The inhibition mechanism was explored...
