Abstract

The cover feature image shows a two-dimensional (2D) colorimetric carbon dioxide (CO2) sensor composed of a gas-permeable polypropylene film (25 μm thick) and a signal transduction hydrogel layer (30 μm thick). The hydrogel layer contained a pH sensitive chromoionophore to indicate the CO2 induced pH change, and a cationic amine to further capture CO2 through the carbamate formation reaction. With this 2D colorimetric CO2 optode, the CO2 release from yeast-catalyzed flour fermentation was successfully monitored. More information can be found in the Research Article by Jingying Zhai, Xiaojiang Xie, and co-workers.

封面:一种基于离子交换剂和色离子团掺杂水凝胶的可调比色二氧化碳传感器。参议员6/2023)
封面特征图显示了一个由25 μm厚的透气性聚丙烯膜和30 μm厚的信号转导水凝胶层组成的二维(2D)比色二氧化碳(CO2)传感器。水凝胶层含有一个pH敏感的色离子团,表明CO2引起的pH变化,以及一个阳离子胺,通过氨基甲酸酯形成反应进一步捕获CO2。利用这种2D比色CO2光电仪,成功地监测了酵母催化面粉发酵过程中的CO2释放。更多信息可以在翟靖颖、谢晓江和同事的研究文章中找到。
