Summary: The performance of a perylene monoimide annihilator in a photochemical upconversion composition shows promising results, outperforming the commonly used rubrene annihilator at low excitation intensity. However, its performance is hindered under strong excitation due to a low annihilation singlet yield. The upconversion composition utilizing perylene monoimide is capable of utilizing more than 12% of the generated triplet states to generate emissive, excited singlet states under one sun illumination, potentially enhancing the energy conversion efficiency of high band gap solar cells.

Summary: A first principles model is developed to describe the dissolution mechanism of phosphate ore particles in a solution of phosphoric acid. The model accounts for non-uniform size of ore particles using particle size distributions and quantifies their influence on the model predictions. A global estimability analysis is carried out to determine the estimable parameters from experimental data, and the predictions show good agreement with the experimental data. The computed activation energy indicates that diffusion is the rate limiting step of the dissolution process.
