How microspheres are formed?

How are microspheres formed? In general, the microspheres were formed by coagulating a solution of alginate in the form of fine droplets with a calcium chloride solution (Martinsen et al.. Unassembled alginate microspheres with an average diameter of 8 μm were produced via an emulsification process (see Fig. 15b)) by Lemoine et al. (1998). What … Read more

Why does ice float after it crystallizes its specific gravity is greater than water its density is greater than water its density is less than water air trapped in ice causes it to float?

Why does ice float after it crystallizes, its specific gravity is greater than water, its density is greater than water, and its density is less than the watery air trapped in the ice that causes it to float? Why does ice float in water higher than the density? Ice floats because it is less dense … Read more
