Centrifugation is a separative technique used in phase separation of dispersions, emulsions, and other formulations across many industry sectors. In some cases, it can be used for accelerated stability analysis because it enables to apply strong gravitational stress on the sample, which results in faster separation.

The viscous properties of a liquid or amorphous solid are primarily determined by inter-particle forces within the solution, including friction and attraction between molecules in the macrostructure. These Van der Waals forces are critical facets of a sample’s resistance to deformation, or flow, which defines the material’s viscosity.

Drug stability testing is a critical stage of R&D, quality control (QC), and quality assurance (QA) for pharmaceutical products. It typically comprises accelerated ageing of a product under simulated use conditions to determine the shelf life of solid phase or colloidal pharmaceuticals.

Approaching deadline for Sulfur Cap at 0,5% requires fast compliance
Recent restrictions on Sulfur Oxides emissions in ships are to be enforced by 2020. The IMO - International Marine Organization - has decided on limiting the maximum amount allowed to 0,5%, a cap that has already been established in Europe and Americas but still needs to be applied worldwide. Tens of thousands of ships are affected and time to comply is short.

Materials science is the complex interdisciplinary field associated with the discovery, manufacture, and application of novel material arrangements. It is fundamentally concerned with understanding the physiochemical structure of a liquid, solid, or amorphous material, as well as its properties, performance, and processing capabilities. These overarching principles are known as material characterization.

Microstructural thermal stability determines the likelihood of a material to undergo phase transitions in response to thermal stress, which may occur due to the manufacturing process or storage conditions. It is a critical metric in the formulation of complex solutions containing lipids such as fatty molecules or oils.

Rheological studies of complex materials used in various industries (Coating, Pharma, Food…) are a challenging task which requires strong expertise. The measurement range and operating conditions are often limited due to the material structure (i.e. risk of denaturation) and the instrument used, which may require extrapolation and modelisation of data. Rheometers are used to analyse the complex flow characteristics of materials by subjecting a sample to various types of stress, such as shear stress and deformation. Established rheometric instruments require various geometries to provoke changes in samples and determine the relationship between measured parameters (shear viscosity, elastic and viscous moduli, etc.) and applied force. These measurements require deep knowledge of rheology and fluid mechanics in order to perform high quality analysis. It is essential to properly adapt the geometry to the measured fluid properties and conditions.

Pharmaceutical products comprise strictly controlled ratios of inert carrier media to biologically active ingredients (AIs). The carrier is designed to act as a delivery method for the active ingredient to facilitate the drug’s therapeutic action with enhanced locality. Solid phase pharmaceuticals such as capsules and tablets are basic in terms of their target specificity. These drugs must be ingested before the AIs can permeate through the blood barrier, often with significant delays before any therapeutic action occurs.

Graphene is a unique material with electromechanical properties which have sparked a revolution in the field of materials science. Although allotropic with carbon, graphene exhibits behavior between that of a metal and a non-metal. It can be described as a semiconductor like silicon, although with vastly improved electrical conductivity. This is because graphene is comprised of a single sheet of carbon-carbon bonds arranged in a two-dimensional lattice, representing a longer mean free path for electrons to travel through. Alongside these outstanding electrical properties, graphene is incredibly strong, lightweight, and formable – but these properties are difficult to reproduce.

The stability of suspensions used for the electronic field is critical for guaranteeing the level of quality associated with high-technology end-products. For example, ultra-high definition displays rely on unique optical coatings and surface engineering of thin film structures to generate images of high-quality. Chemical-mechanical polishing (CMP) uses slurries to polish the surfaces of semiconducting materials. The functionalities of fuel cells and batteries are improved with solution-processed nanoparticle coatings. There are myriad examples of the use of suspensions in established and cutting-edge electronic applications. Stability tests of suspensions can ensure that electronic devices in commercial and industrial spaces are fit for requirement.
