objective(s): a box-behnken design was used for evaluation of eudragit coated diclofenac pellets. the purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. materials and methods: diclofenac was loaded onto the non-pareil beads using conventional coating pan. film coating of pellets was done at the same pan. the effect of pla...

We study the curing of epidemics of a network contagion, which is modelled using a variation of the classical Polya urn process that takes into account spatial infection among neighbouring nodes. We introduce several quantities for measuring the overall infection in the network and use them to formulate an optimal control problem for minimizing the average infection rate using limited curing re...

Different intermittent curing methods were conducted for pulsed laser induced photopolymerization reactions in a TMPTA acrylic system. Two methods of curing were compared, named grouped pulses impingement (GPI) and consecutively pulsed curing (CPC), respectively, in which the total number of the curing pulses were kept same. In GPI, a prominent light diffraction effect was observed in the post ...

Furfurylation of wood is of interest worldwide as an environmentally friendly modification process. It is widely assumed that low-molecular weight furfuryl alcohol (FA) can penetrate into wood cells and polymerize in-situ during the process, resulting in substantial improvement in the physical-mechanical properties and durability of wood. In this study, confocal laser scanning microscopy (CLSM)...

Mud solids entrained in clarified juice have an adverse effect on subsequent sugar curing and may retard refinery filtration rates if occluded in raw sugar crystals. Entrainment may be caused by refractory juices or instability of process control and may itself lead to unstable processing rates due to retarded curing rates and molasses recirculation. The adverse effects may therefore be quite p...

Automotive topcoat curing is critical to the quality of the final coating. In production, topcoat curing quality is commonly judged through the evaluation of sample panel temperature-time series data from the finished product directly against the cure window that is specified for the polymeric coating material used. This inspection-based post-process quality control (QC) is not only methodologi...

In the field of soft robotics, hydrogels possess material properties that allow them to function as both soft strain sensors and electrodes for dielectric elastomer actuators. However, there is still much that needs to be understood about the curing process of hydrogels and the resulting material characteristics before devices can be reliably manufactured. In this study, we investigated the eff...
