An intrinsically self-healing and anti-freezing molecular chains induced polyacrylamide-based hydrogel electrolytes for zinc manganese dioxide batteries

The anti-freezing strategy of hydrogels and their self-healing structure are often contradictory,it is vital to break through the molecular structure to design and construct hydrogels with intrinsic anti-freezing/self-healing for meeting the rapid development of flexible and wearable devices in diverse service conditions.Herein,we design a new hydrogel electrolyte(AF/SH-Hydrogel)with intrinsic anti-freezing/self-healing capabilities by introducing ethylene glycol molecules,dynamic chemical bonding(disulfide bond),and supramolecular interaction(multi-hydrogen bond)into the polyacrylamide molecular chain.Thanks to the exceptional freeze resistance(84%capacity retention at-20℃)and intrinsic self-healing capabilities(95%capacity retention after 5 cutting/self-healing cycles),the obtained AF/SH-Hydrogel makes the zinc||manganese dioxide cell an economically feasible battery for the state-of-the-art applications.The Zn||AF/SH-Hydrogel||MnO_(2)device offers a near-theoretical specific capacity of 285 m A h g^(-1)at 0.1 A g^(-1)(Coulombic efficiency≈100%),as well as good self-healing capability and mechanical flexibility in an ice bath.This work provides insight that can be utilized to develop multifunctional hydrogel electrolytes for application in next generation of self-healable and freeze-resistance smart aqueous energy storage devices.

Cadmium nanoclusters in a protein matrix： Synthesis, characterization, and application in targeted drug delivery and cellular imaging

Biotemplated 金属 nanoclusters 在 biosensing， bioimaging，催化作用，和 nanomedicine 由于他们潜在的应用的宽范围积累了许多注意。这里，我们报导马厩的合成， biocompatible，水溶性、高度荧光灯的牛的浆液白朊模板镉 nanoclusters (Cd 通过一个灵巧的一个壶绿色方法的 NC ) 。我们 covalently 结合了玻尿的酸(哈) 到 Cd 形成的 NC 一 pH 应答，有为 doxorubicin (纪录影片) 的持续版本侧面的 tumortargeting theranostic nanocarrier，模型 anticancer 药。nanocarrier 显示出大约 75.6% 的纪录影片封装效率。纪录影片版本侧面表明 74% 纪录影片在 pH 被释放 5.3，当不到 26% 纪录影片在 pH 被释放时 7.4 在一样的 24-h 时期以内。nanocarrier 有选择地认出了表示 CD44 的 MCF-7 乳癌房间，房间表面受体为哈，而没有如此的识别被观察与哈受体否定的 HEK293 房间。nanocarrier 的 Biocompatibility 与 HEK293 和 MCF-7 房间通过 cytotoxicity 试金被评估。展出的 nanocarrier 对没有 cytotoxicity 很低，而装载纪录影片的 nanocarrier 显示出可观的细胞的举起并且提高了 MCF-7 乳癌杀死房间的能力。我们也证实了使用的可行性高度荧光灯为 MCF-7 和 HeLa 房间的 bioimaging 的 nanoconjugate。优异的指向的药交货功效，细胞的成像能力，和低 cytotoxicity 用有希望的生物医学的应用作为令人激动的新 nanoplatform 放这 nanoconjugate。
