Esterification of citric acid with locust bean gum
2019年8月1日 · Esterification of citric acid (CA) with locust bean gum (LBG) was prepared by hydrochloric acid (HCl) as a catalyst and UV irradiation (254 nm) as esterification energy. This study aims to determine the best conditions of esterification.
DSC and TMA studies on freezing and thawing gelation of …
2012年3月20日 · In this study, LBG hydrogels were prepared by freezing and thawing by varying the cooling rate and the effect of cooling rate on gelation is investigated by TMA in water. By differential scanning calorimetry (DSC), melting of ice in the gels and melting enthalpy are also related with cooling rate.
DSC曲线上能看到什么？ - 知乎专栏
玻璃化转变温度，简称Tg，是高分子材料发生玻璃态与高弹态转变时候的特征温度，在DSC曲线上表现为一个斜坡状的曲线，通过对这段曲线进行出来我们就能得到样品的玻璃化转变温度（如下图）。 那么我们求样品玻璃化转变温度（Tg）有什么意义呢？ 上面我们说到过，Tg点也就是发生在样品玻璃态与高弹态转变时候的温度，那么何为玻璃态？ 高弹态又是什么？ ，如字面上的意思，玻璃态代表材料像玻璃一样坚硬。 高弹态代表材料像橡胶一样有弹性。 这是高分子材料随 …

半乳甘露聚糖多糖冻融凝胶的DSC和TMA研究 - X-MOL
2012年3月1日 · 摘要 在已知可形成水凝胶的各种多糖中，由甘露糖主链和半乳糖侧链组成的刺槐豆胶（LBG）具有独特的特性，因为 LBG 通过冷冻和解冻形成水凝胶。 在这项研究中，通过差示扫描量热法 (DSC) 和热机械分析 (TMA) 研究了热历史对凝胶化的影响。 发现通过称重法计算的凝胶/溶胶比受溶胶浓度、冷冻速率和冻融循环次数（n）的影响。 一旦形成 LBG 水凝胶，它们就具有热稳定性，尽管当 n 增加时观察到脱水收缩。 通过 TMA 在水中测量的水凝胶的动态杨氏模 …
怎么理解DSC的数据？ - 知乎专栏
差示扫描量热仪 （Differential Scanning Calorimetry, DSC）是测量关键参数的重要工具，通过DSC可以测量物质的 玻璃态转变温度 Tg’和 熔融温度 Tm这些关键参数。 目前也有很多测试机构可以提供DSC测试服务，当把样品送到机构检测之后，机构往往会给出一张测试图。
