Accounting for photodegradation dramatically improves prediction of carbon losses in dryland systems

Ecosphere, 2017
Traditional models of decomposition fail to capture litter mass loss patterns in dryland systems. This shortcoming has stimulated research into alternative drivers of decomposition, including photodegradation.

Concave microlens arrays with tunable curvature for enhanced photodegradation of organic pollutants in water: A non-contact approach

, 2023
Solar-driven photodegradation for water treatment faces challenges such as low energy conversion rates, high maintenance costs, and over-sensitivity to the environment. In this study, we develop reusable concave microlens arrays (MLAs) for more efficient
