Spray Drying 4.0: Real-Time PAT, AI Process Control, and What Engineers Actually Gain
Process analytical technology combined with machine learning is changing residual moisture control and yield prediction in pharmaceutical and food spray drying. The gains are real but bounded, and the off-line test panel has not been replaced.
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.
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.
Calcium Carbonate Powder in Polypropylene: Dust Suppression and Dosing Errors
Dust suppression oil can reduce airborne calcium carbonate dust, but it may also increase powder cohesion. In polypropylene compounding, that change can disturb loss-in-weight feeder refill behavior, causing bridging, rat-holing, delayed settling, and unstable screw feed. Before changing the feeder hardware, check whether the calcium carbonate surface treatment has altered the powder’s flow [...]
Real-Time Particle Characterization and Process Control
Real-time particle characterization is moving powder processing from delayed laboratory checks toward inline sensors, soft sensors, and hybrid models that support faster process decisions. The major shift is the interpretation of sensor signals through particle-scale mechanisms. Pressure, vibration, acoustic, optical, thermal, and process data can increasingly be linked to changes in particle size, [...]
