What is the best predictor of word difficulty? A case of data mining using random forest. Is “general” easier than “academic”? A corpus-based investigation into the two modules of IELTS reading...

开发了一种新的二硫键交联策略，可从巯基修饰的HA制备透明质酸（HA）水凝胶。 首先，合成二硫代双（丙二酰肼）（DTP）和二硫代双（丁二酰肼）（DTB），然后通过碳二亚胺化学方法与HA偶联。

A new disulfide cross-linking strategy was developed to prepare hyaluronic acid (HA) hydrogel from thiol-modified HA. First, dithiobis (propanoic dihydrazide) (DTP) and dithiobis (butyric dihydrazide) (DTB) were synthesized and then coupled to HA with carbodiimide chemistry. Next, disulfide bonds of t …

HA-dithiobis (butyric dihydrazide) (HA-DTB) was prepared in the same way to the synthesis of HA-DTP. The number of disulfide linkages formed increased when the thiol groups were oxidized by hydrogen peroxide (H 2 O 2) rather than air.

HA is a naturally occurring unbranched glycosaminoglycan (GAG), a polyanionic polymer of high molecular weight that exhibits unique viscoelastic properties, excellent biocompatibility, and biodegradability. These properties of HA-derived hydrogels make them ideal biomaterials for tissue engineering.

DTB (Draft tube baffled)结晶器带有搅拌装置，可以为蛋氨酸的生产提供分布均匀的生长环境，且作为一种典型的晶浆内循环型结晶器，DTB结晶器可以不断地消耗过饱和度，使之维持在较低水平，因此，工业上常选用DTB结晶器作为蛋氨酸的生产设备。
