  • Chemical Imaging of Industrial and Healthcare Materials by ToFSIMS

    Chemical imaging is a powerful tool that can be applied to a wide variety of applications. Time-of-Flight Secondary Ion Mass Spectrometry (ToFSIMS) is an advanced technique that provides information about the chemistry of the surface of samples and allows analysts to also spatially map the chemistry of the surface. To obtain a more in-depth profile of analytes, ToFSIMS is often used in conjunction with other surface analysis techniques but, as a standalone technique, it still offers valuable insight into the surfaces of materials. This white paper will discuss the power of ToFSIMS across a range of different industries and materials and the specific information and value provided.

  • The Use of Digital Image Correlation in Masonry Research

    Digital Image Correlation (DIC) is a technique which can deliver video film of the strain development on the surface of a material due to loading or other actions. Lucideon has recently used the technique on concrete masonry for the first time with some extraordinary results. This paper describes the technique and how it was used on two projects. The first project was to study the strain development in masonry walls made from Autoclaved Aerated Concrete (AAC) and dense aggregate concrete and subjected to a single concentrated load. The results illustrate clearly that the material beneath the point of load application was the most heavily compressed and that the pressure is gradually dissipated from the point of load application with contours of equal principal compressive stress in ‘bulb’ shapes. On failure the heavily compressed zone beneath the loading plate effectively became “part of the loading plate” in a similar way as soil under a foundation. The second project studied walls made from storey-height panels of AAC, jointed vertically by mortar, and subjected to a concentrated vertical load. In this case, the load effects were transmitted across the vertical joint indicating that more than one panel resisted the load until just prior to failure, which was by the joint failing in shear. The results were used to improve design provisions for walls subjected to concentrated loads.

  • Drying Processes - the Balance Between Efficiency and Product Quality

    Drying is an important process in almost all industry sectors, including ceramics, pharmaceutical, food, chemical, construction and semiconductors. This process is always concerned with two main criteria, maximizing the product efficiency and maintaining the product quality. However, in most cases, an efficient drying process often requires a high temperature to promote the evaporation of the water or any solvent from the product.
    Harsh thermal conditions can affect the product quality, i.e. lead to cracks and distortion in ceramic products, or cause deactivation of key ingredients or undesired phase transitions for food and pharmaceutical products, etc. On the other hand, to maximize product quality, a moderate temperature could be selected, which leads to low process efficiency, i.e. prolonging the drying cycles. As a result, there seems to be a dilemma between efficiency and quality inherent to the drying process. This dilemma can be resolved either by the proper selection of drying methods/dryer types or the optimization of the drying profile.

  • The Value of Drying - Choosing the Right Equipment and Methods

    Drying is an important and often necessary unit operation for many processes. It can determine the quality of the final product, determine its shelf life or expose imperfections and lead to defective products. It is also very energy intensive and time consuming, so a lot of attention should be paid to optimizing the drying step in order to make the overall process competitive.
    Drying is the removal of water or other solvents from the product, firstly from the surface, then from the pores and cracks. If done too quickly, the solvent leaves a weak structure behind and this could cause fractures or imperfections, as seen in the ceramic industry. If done at too high of a temperature, it could degrade the product, a common issue in the pharmaceutical and food industry. Moreover, drying can be a hazardous step as the removal of the solvent (when drying paints and coatings for example) can create an explosive atmosphere.

  • Your Metal Component has Failed in Fatigue: What do you do next?

    Fatigue is a major failure mode for metal components, in commercial, industrial and research environments, and can have catastrophic consequences. Understanding the mechanisms behind fatigue failures, and knowing how to handle samples after they have failed in fatigue, is essential for engineers to perform effective analysis.

  • Offsite Construction: The Relevance of Full Scale Testing

    In recent years, Lucideon has seen large numbers of wall, floor and roof systems passing through its laboratories, usually for testing to one ETAG or another; the scopes are often rather unclear. The focus, however, is nearly always on the testing of the panels and rarely whole assemblages. The purpose of this paper is to show some examples where the results from whole building tests have demonstrated distinct improvements in performance due to particular details or elements, or simply overall robustness, not evident from tests on sub-assemblies. The aim is to raise awareness that despite there being established testing regimes for potential offsite or pre-manufactured approaches, a test on the complete assemblage may provide surprisingly beneficial results.

  • Single Use Systems in the Pharmaceutical Industry - Advantages and Considerations

    SUS can make it easier for pharmaceutical manufacturers in terms of process operation and minimizing risk of contamination. Downtime can also be greatly reduced as SUS components are delivered ready for use, and are designed so that one component can quickly be interchanged with another, clean replacement, between runs or when changing to a different product on the same line.
    SUS do however still pose challenges themselves, which need careful planning and consideration to maximize the benefit from them whilst ensuring patient safety and product integrity.
    In this paper we will discuss some of the testing and validation considerations that pharmaceutical manufacturers should look at when implementing SUS, as well as other factors that can help them to optimize their usage.

  • Failure Analysis of Plastic Products

    The extensive application of polymer materials nowadays is inevitably accompanied by the occurrence of product failure, which is costly for all organizations involved. The consequence of failure varies from loss of asset and brand credibility, to costly legal disputes, and catastrophic human casualties. This paper provides some insights into the failure of plastic products and gives an introduction to some of the analytical techniques commonly used in failure diagnosis. An understanding of the background knowledge of plastic materials and the methods generally adopted when conducting a failure analysis will help to not only investigate a failure, but can also determine the right corrective solutions.

  • Design Optimization in Medical Devices: Materials Matter

    The development of revolutionary products, the meeting of legislative requirements or the replacement of raw materials phased out by third party suppliers are just some of the critical reasons that device engineers may seek new or alternative materials. The unique and immeasurably diverse range of materials available for medical devices offers many possibilities for design and function. In this white paper, we demonstrate the risk of working with the wrong material, highlight the upside when the right material is selected, and outline what the selection process looks like. In addition to material selection, we also look at material processing and discuss how understanding how the two are unified in the actual design and function of the process is the ultimate key to success.
