为拓展功能皮革的制造方法,以羧基化纤维素纳米纤维(CCNF)、硅烷偶联剂(KH560)和聚乙烯亚胺(PEI)为原料制备了纳米纤维素基复合气凝胶(CSP-AG)。通过调控CCNF、KH560和PEI间的配比制备了不同的CSP-AGs,考察了其结构与基本性质以及CSP-AG在生物基醛鞣革涂饰中的应用性能。结果表明,不同组分配比下,CSP-AG均具有良好的力学强度和低密度(最低为0.026 g/cm^(3))。KH560可与PEI和CCNF进行有效反应,形成多孔网络结构,且两者在网络结构中的分布均匀。此外,CSP-AG的热稳定性良好,其导热系数低(最低为0.042 49 W/(m·k))。涂饰应用结果表明,相较于未经涂饰的革样和经三防整理剂(SF)涂饰的革样,经SF-AG涂饰的革样具更优的隔热和疏水性能且革样难燃。

最近的证据表明，在动物模型中，肠道病理学和微生物组与高血压之间存在联系。然而，这种关联在人类中是否存在尚不清楚。因此，该研究的目的是检验高血压患者具有明显特异的肠道微生物组以及肠上皮屏障功能标记物和微生物组组成可以预测收缩压变化的假设。研究者通过鸟枪法宏基因组学分析粪便样本显示微生物分类和功能变化，结果显示高血压患者和对照受试者之间丁酸盐产生存在差异。
