Computational Strategies for Predicting Excited‐State Energies in Eu3+ Down‐Shifting Spectral Converters for Photovoltaic Devices

open access: yesChemPhysChem, EarlyView.
A computational strategy to compute the energy of the triplet excited state in europium‐based coordination complexes is presented. This method allows for in silico screening of new systems with can be used as photosensitizers in solar cell‐based technologies.

Guided Sample Pooling in Human Mass Balance Studies: A Recommended Strategic Decision Framework

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Radiolabeled human mass balance studies are crucial for identifying circulating metabolites and understanding drug absorption, excretion, and clearance pathways. Metabolite profiling involves quantifying all drug‐related entities, including parent drug and metabolites in plasma and excreta, using extended liquid chromatography methods coupled with ...

Theoretical and experimental comparison of an ultra-high-speed laser data transmission system [PDF]

open access: yes
The performance of a digital optical data transmission system is specified by the probability that the system erroneously decides a signal has or has not been transmitted. Two factors which induce signal fading and thereby decrease system performance are
