Paints and coatings are highly complex multi-component systems that pose many challenges for the formulation chemist. Ongoing control of raw materials and final formulations is essential for ensuring product quality and customer satisfaction, while an in-depth understanding of physical properties is necessary to devise new formulations. This white paper discusses these challenges, and explains ...

Nickel laterite in the Sorowako and Petea area of South Sulawesi, Indonesia, is classified into one of two main types, depending on the bedrock and silica-to-magnesia ratio in the mineralization: West Block and East Block. The East Block mine is high-recovery, low-olivine (∼60­–65%)parent rock, whereas West Block is low-recovery, high-olivine (∼80–90%)parent rock. Petea is a mainly lateritic ...

DSC is a trusted and proven technique for protein thermal stability screening in vaccine development. Due to the wide operating temperatures, clear indication of the transition stage and straightforward operating conditions that do not compromise protein stability, DSC can achieve the highest standards of screening. By accurately determining the Tm and exact protein stability profile, DSC ...

Progressing drug development without fully understanding the structure and stability of polymorph variants can quickly lead to potential safety, efficacy or quality issues. Gaps in polymorph profiling can also lead to ambiguity in patent applications, which can have disastrous consequences even years into a drug product’s lifecycle. A clear understanding of an API and all its forms - through ...

DLS and ELS are versatile techniques that are used to characterize the size and zeta potential of particulate materials. They are most commonly applied to colloidal systems, nanoparticles and macromolecules in solution or dispersion. Of course, the specifications of a DLS/ELS instrument are vital when comparing systems from different manufacturers. But if you don’t use your system in the ...

Scientists, researchers, and quality control managers around the world use laser diffraction for particle size analysis. But, to develop truly high-performance products, you often need deeper insights than those provided by laser diffraction alone. In particular, to understand the influences behind packing, flow, and dissolution rate, you need to understand how particle size and shape affect ...

IntroductionCatalytic materials are important for a wide variety of applications from their use in the chemical industry to the utilization in solar energy production to everyday applications such as automotive catalysts. There are three main types of catalysts; heterogeneous catalysts, homogeneous catalysts, and biocatalysts (enzymes), with heterogeneous catalysts the most studied via X-ray ...

Modern industrial processes rely on a growing range of sophisticated technologies to ensure the quality of materials and finished products. The more these systems become embedded, the heavier the reliance on their abilities to perform consistently and to deliver essential data for critical decision-making. And the greater the risk, should they fail to do so. Investing in technology solutions ...

The accurate and efficient measurement of intermolecular interactions and binding events is a critical element for all manner of basic research and an indispensable component of drug discovery programs. Ligand binding assays can be performed using labeled molecules (radiolabels, fluorescent labels, etc.), but appropriate, non-disruptive labeling and often elaborate washing and purification ...

Unsupported or ageing technology presents business-critical risks to continuity, productivity and output in today’s fast-moving, high-tech laboratory environments where skills and practices have changed dramatically in recent years. Investing in new technology means weighing up the true costs of inaction versus the benefits of staying ahead and what that means for your business. In April ...
