Abstract- Nuclear Decommissioning Authority (NDA) announced that all the reprocessing activities at the Sellafield will cease by 2020, and the operations will focus on waste management, completely clean out, and other decommissioning activities. However, decommissioning of Sellafield poses many challenges since the design and commissioning of the plant was not made considering the decommissioning in mind.[…]
Introduction Chemical weapons were first deployed and used in World War I and II. Chemicals weapons are particularly effective in destroying enemies during war. Presently, there are over 50 different types of chemicals developed to be primarily used as chemical weapons (Bentley, 2018). As multiple states began using chemical weapons, this resulted in the banning[…]
Colloid science deals with systems comprising molecules/particles with different dimensions, ranging from smaller (nanometer (10-9m) to larger (micrometer (10-6m) molecules/particles. As these systems contain a mixture of particles with different sizes, colloid systems are heterogeneous in nature. Colloid systems are very important as they have a wide range of applications, including adhesion, chromatography, detergency, precipitation,[…]
ABSTRACT Rheological properties of concentrated suspensions depend substantially on their structure; that is, on the formation of aggregates due to colloidal forces between particles. The aggregate size distribution is determined by the correlation between colloidal, Brownian and hydrodynamic forces in the system. Therefore, an investigation of the rheological properties of a suspension will provide valuable[…]
