Covalent organic frameworks (COFs) are typically synthesized using solvothermal conditions (>120 °C, >72 hours) in harmful solvents. Here we report a strategy to rapidly (<60 minutes) synthesize imine-linked COFs aqueous acetic acid sonochemistry and thus avoid most of the disadvantages methods. Using sonochemical method, our knowledge previously unreported COFs. The crystallinity porosity thes...

1. Introduction Together with the chemical effects of ultrasound, light is often emitted [1-5]. Such sonoluminescence provides an extremely useful spectroscopic probe of the conditions created during cavitation bubble collapse. Acoustic cavitation is the origin of both sonochemistry and sonoluminescence. The collapse of bubbles caused by cavitation produces intense local heating and high pressu...

This paper describes synthesis of In2S3 nanoparticles by sonochemistry method and their application to enhance solar cells performance which In2S3 nanoparticles work as co-sensitizer for the first time. In2S3 is a narrow band gap semiconductor (2 eV) with conduction band higher than TiO2. Therefore it can transfer electron to the conduction band of TiO2. The effect of different parameters such ...
