Evaluation of an inertial measurement unit-based approach for determining centre-of-mass movement during non-seated cycling.

J Biomech 2021 Apr 19;126:110441. Epub 2021 Apr 19.

Centre for Sensorimotor Performance School of Human Movement and Nutrition Sciences, The University of Queensland, St Lucia, Queensland, Australia.

Instantaneous crank power does not equal total joint power if a rider's centre of mass (CoM) gains and loses mechanical energy. Thus, estimating CoM motion and the associated energy changes can provide valuable information about the mechanics of cycling. To date, an accurate and precise method for tracking CoM motion during outdoor cycling has not been validated. Read More

Interacting Quantum Atoms Analysis of the Reaction Force: a tool to analyse driving and retarding forces in chemical reactions.

Chemphyschem 2021 Jul 22. Epub 2021 Jul 22.

Universidad de Oviedo Facultad de Quimica, Departamento de Química y Física Analítica, SPAIN.

The analysis of the reaction force and its topology has provided a wide range of fruitful concepts in the theory of chemical reactivity over the years, allowing to identify chemically relevant regions along a reaction profile. The reaction force (RF), a projection of the Hellmann-Feynman forces acting on the nuclei of a molecular system onto a suitable reaction coordinate, is partitioned using the interacting quantum atoms approach (IQA). The exact IQA molecular energy decomposition is now shown to open a unique window to identify and quantify the chemical entities that drive or retard a chemical reaction. Read More

Radiative analysis of luminescence in photoreactive systems: Application to photosensitizers for solar fuel production.

PLoS One 2021 22;16(7):e0255002. Epub 2021 Jul 22.

Université Clermont Auvergne, Clermont Auvergne INP, CNRS, Institut Pascal, F-63000 Clermont-Ferrand, France.

Most chemical reactions promoted by light and using a photosensitizer (a dye) are subject to the phenomenon of luminescence. Redistribution of light in all directions (isotropic luminescence emission) and in a new spectral range (luminescence emission spectrum) makes experimental and theoretical studies much more complex compared to a situation with a purely absorbing reaction volume. This has a significant impact on the engineering of photoreactors for industrial applications. Read More
