A mechanism on the drug release into a perfect sink from a coated planar matrix with a super-saturation loading in the core
Coated planar matrix Controlled release Mathematical analysis In-vitro release

A comprehensive model is proposed to accurately describe drug release kinetics from a coated plane sheet when drug loading in the core is above its saturation level. The general solutions are acquired...
利用扫描电子显微镜、傅里叶红外光谱仪和视频光学接触角测量仪对蜻蜓翅膀表面的微观结构、物质成分以及疏水性进行了研究，分析了蜻蜓翅膀表面微观结构、物质成分与翅膀表面疏水性能间的关系。结果表明，蜻蜓翅膀表面分布大量纳米级乳突结构，致使液滴与翅膀表面形成复合接触，增强了翅膀表面的疏水性；翅膀表面覆盖的蜡质层对蜻蜓翅膀表面的疏水性起增强作用。此外，利用Cassie模型建立了蜻蜓翅膀表面疏水方程，并进行了蜻蜓...
