Advanced Healthcare Materials, EarlyView.A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

The rotor dynamics of reeling machinery
Applied Mathematical Modelling, 1999 Wide-faced rotors for high-speed reeling operations such as those employed in paper manufacture, printing, coating and laminating are considered, and the torsional behaviour of these units is investigated. Modeling, simulation and analysis techniques are involved enabling the prediction of the torsional vibrational signature of high-speed assemblies ...

Dynamic Analysis of Composite Rotors [PDF]
International Journal of Rotating Machinery, 1996 An outline of formulation based on a layerwise beam theory for unbalance response and stability analysis of a multi mass, multi bearing composite rotor mounted on fluid film bearings is presented. Disc gyroscopics and rotary inertia effects are accounted for. Material damping is also taken into account.
