Photocatalytic Water Oxidation The art representing article number 2203102 by Nathan I. Hammer, Jared H. Delcamp, and co-workers depicts the organic molecular photosensitizer QL11-OEG being irradiated with visible light under water. strong photooxidant is in a 16 microsecond long-lived excited state near ruthenium-based water oxidation catalyst. oxidizing catalyst to drive conversion of molecul...

In the construction industry, non-destructive testing (NDT) methods are gaining more popularity for their ability to examine the in-situ component properties without damaging the structure. One of the most common NDTs for measuring the concrete compressive strength on site is the Rebound Hammer Test. Using the rebound value obtained from the test hammer, the concrete compressive strength can be...
