About the Scholar: Zijun Zhang grew up in China and attended The Experimental High School Attached to Beijing Normal University
Tissue engineering encourages the body to replace damaged tissues or organs with tissues grown in the body from laboratory-generated cells. Three-dimensional scaffolds guide cellular growth and support new tissue formation. Scaffolds made from chitosan, derived from the exoskeletons of crustaceans, work best, but require the addition of PVA and sometimes other additives for strength and durability. The experiment Zijun proposes in this paper is designed to determine if a particular molecular weight of chitosan, combined with PVA at a 1:1 ratio, can produce optimal results, identifying molecular weights that are most suitable for use as scaffolds without additional additives.
Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth.
