  • echnical comparison of powder flowability at 25°C and 150°C, showing smooth powder behavior at room temperature and clumped, uneven flow at elevated temperature.
    27 June 2026

    Powder Flowability at Elevated Temperature: Why Room-Temperature Results Don’t Predict Hot-Bed Behavior

    Temperature shifts surface energy, contact compliance, and residual moisture state in ways that can reverse a powder's ambient flow behavior. This Insight explains the dominant mechanisms across three temperature ranges and what elevated-temperature testing reveals for SLS powder beds, spray dryer outlets, and heated conveying systems.

  • Technical comparison of copper powder morphologies used in electrification applications, including dendritic, spherical, irregular, and flake copper particles.
    27 June 2026

    Copper Powder for Electrification: Why Morphology, Purity, and Packing Density Are Now Engineering Variables

    Sintered contacts, additive manufactured heat exchangers, EV motor components, and conductive pastes each require a different copper powder. This article explains why morphology, particle size distribution, oxygen content, and packing density are engineering variables, and how to specify them correctly for electrification applications.

  • Macro view of pharmaceutical powder particles, crystals, and lipid droplets at the interface with an aqueous medium, illustrating surface contact and early dissolution of poorly soluble APIs.
    20 June 2026

    Poorly Soluble APIs: How Surface Contact Shapes Dissolution and Bioavailability

    Poorly soluble APIs now represent the majority of the pharmaceutical development pipeline. Dissolution and oral bioavailability are determined by molecular solubility, surface wetting behavior, solid-state stability, and how the formulation interacts with the GI environment from first contact onward. Amorphous dispersions, lipid systems, nanocrystals, and co-crystals each rely on different surface mechanisms to deliver their intended advantage.
