A few weeks ago, we discussed the history of the Lucent360™, our new photoreactor for light and temperatures control for screen to scale, in both batch and flow. This month, we want to share a series of experiments that demonstrate the value of the Lucent360™ for studying a photochemical reaction. This project was brought to us by chemists at the IRCOF and Oril in France*. There is no shortage o..

This month, we highlight the recent work of several students from the Balasubramanian Lab at the University of Cambridge using the EvoluChem™ Photoredox Boxes in their graduate studies. Shankar Balasubramanian is a godfather in the field of nucleic acid chemistry and methods to sequence epigenetic modifications. In recent years this work has involved visible-light applications. Ben Mortishire-Sm..

Like every year we could also h..

H2O2 production from a sustainable catalyst using light and seawater If there is one thing on earth that we have enough of, it is seawater. (And unfortunately, we have a lot more of it each and every day). In fact, 97% of the water on earth is saltwater, 3 % freshwater (broken down as 2% glaciers and ice, less than 1% from groundwater, lakes, and streams). For our purposes, water is a green solv..
