Chemistry – A European Journal, EarlyView.The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Numerical and Experimental Study on Heat Transfer Enhancement by Vortex Generation
Journal of Engineering and Sustainable Development, 2006 Numerical and experimental study was carried out on heat transfer enhancement using a slender delta wing vortex generator to generate longitudinal vortices in a rectangular duct. Numerically, laminar with constant wall temperature was considered. Effect

Deep Underground Science and Engineering, EarlyView.The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Conical Euler analysis and active roll suppression for unsteady vortical flows about rolling delta wings [PDF]
A conical Euler code was developed to study unsteady vortex-dominated flows about rolling, highly swept delta wings undergoing either forced motions or free-to-roll motions that include active roll suppression.
