Web一、. 凝胶领域火了很多很多年了，从一开始就没冷门过，最近十年更是再创新高，因此浮躁的风气影响了一代又一代的研究者。. 很多人只关心堆砌一个怎样的故事能发在更高影响期刊，而忽视这个故事的正确性，理由的坚实性。. 渐渐地也就忽视了对基本物理 ... WebSep 17, 2024 · Based on the Flory–Huggins–Rehner framework, our analytical model phenomenologically illustrates a well-characterized volume phase behavior of engineered tissue mimics as a function of temperature by formulating the ternary mixing free energy of the polymer–solvent system and by generalizing the elastic free energy term. With this ...
