Shi, Yunlei;Xiong, Dazhen;Li, Zhiyong;Wang, Huiyong;Qiu, Jikuan;Zhang, Hucheng;Wang, Jianji research published 《 Ambient CO2/N2 Switchable Pickering Emulsion Emulsified by TETA-Functionalized Metal-Organic Frameworks》, the research content is summarized as follows. In recent years, metal-organic frameworks (MOFs) have been explored as emulsifiers for the fabrication of Pickering emulsions and then used for hybrid material synthesis and interface catalysis. Nevertheless, stimuli-responsive Pickering emulsions stabilized by MOFs have been rarely reported so far, although they are of great importance for fundamental research studies and practical applications. Herein, for the first time, triethylenetetramine (TETA)-functionalized MOFs (ZIF-90/TETA) have been designed, synthesized, and used for fabricating CO2-/N2-response Pickering emulsions. It is shown that even at the ZIF-90/TETA content of 0.25 wt %, the functional MOF can still efficiently emulsify n-hexane and water to form a high internal phase Pickering emulsion. Importantly, the Pickering emulsion can be easily and reversibly switched between emulsification and demulsification by bubbling of CO2 and N2 alternatively at atm. pressure. The possible mechanism of the CO2/N2 switchable emulsion is investigated by zeta potential, water contact angle, interfacial tension, 13C NMR spectroscopy, and an optical microscope. It is found that the acid-base reaction of CO2 with TETA anchored on the surface of ZIF-90 leads to the production of hydrophilic ammonium bicarbonate and carbamate, which results in the emulsification of the Pickering emulsion. However, when N2 is bubbled to remove CO2, the reverse reaction takes place to cause the demulsification of the Pickering emulsion. Moreover, the CO2/N2 switchable Pickering emulsion has been successfully used as a microreactor for Knoevenagel reactions to demonstrate a highly efficient integration of chem. reaction, product separation, and ZIF-90/TETA recycling for a sustainable chem. process.

1H-Imidazole-2-carboxaldehyde is a novel PTP1b inhibitor with potential application to treat type 2 diabetes.
1H-Imidazole-2-carboxaldehyde is a broad-spectrum antimicrobial that has been shown to inhibit the growth of bacteria by interfering with protein synthesis. It binds to the cytosolic protein and receptor molecule, which are involved in the activation of bacterial enzymes. Imidazole-2-carboxaldehyde reacts with anhydrous sodium and copper complex to produce hydrogen bonds, which prevent the formation of the nitrogen atoms necessary for cellular processes. This chemical also has biological properties such as glyoxal, which inhibits bacterial growth by reacting with amino groups on proteins., Recommanded Product: 1H-Imidazole-2-carbaldehyde
