| 摘 要： | 利用差示扫描量热仪（DSC）研究了羟基磷灰石（HA）纳米微粒对丙三醇溶液冻结过程中水合性质及玻璃化性质的影响．实验结果表明在中高浓度HA纳米颗粒对溶液水合性质影响显著．与未加纳米颗粒的溶液相比，溶液结晶量减少，未冻水含量增大．在较低浓度溶液中，加入纳米颗粒后玻璃化温度变化不明显，但反玻璃化温度明显升高；当溶液浓度达到6...

| Abstract: | In order to investigate the effects of nanoparticles(HA) on the vitrification properties of cryprotectant solutions at cryogenic temperatures,the hydration properties,vitrification and devitrification of Glycerol aqueous solutions with different sizes and concentrations of HA nanoparticles were employed by differential scanning calorimeter(DSC).Experimental results indicate that the hydration behaviors can be significantly affected by nanoparticles.Compared with other solutions without nanoparticles the cry... |
