Long-Acting Injectable Nanoparticle Technologies

Wet milling "The major manufacturing technique for commercially preparing nanosuspensions is wet milling, in which the active agent, in the presence of surface stabilizer(s), is broken down in size by milling media. Media milling can be considered a modernized version of the earlier ball mill, which used larger spheres in a dry state.

The milling efficiency was not satisfactory in case of ratio 1:0.5, but it increased linearly on increasing the amount of the milling media and the milling time except in case of ratio 1:4. It was found that the increase of the amount of the milling media (up to 1:2 w/w or more) causes gray coloring because of the high friction between the ...

Functions of Wetlands | UNL Water

Wetlands serve many functions and values that often go unnoticed. They are particularly valuable components of the ecosystem. Much of this stems from their habitat for fish and wildlife, as well as for protecting water quality, erosion prevention, flood storage and recreation. Their cleansing power provides natural pollution control and the way they filter and collect sediment

Water absorption is the amount of water taken up by flour to achieve the desired consistency and create a quality end-product. It is the optimal amount of water you can add to a dough before it becomes too sticky to process. It is usually defined by flour weight. For example, 60% water absorption means 60 lbs of water is used to hydrate 100 lbs ...
