TRACKING ULTRAFAST REACTIONS IN ORGANIC MATERIALS THROUGH VIBRATIONAL COHERENCE: VIBRONIC COUPLING MECHANISMS IN SINGLET FISSION

Tracking ultrafast reactions in organic materials through vibrational coherence: vibronic coupling mechanisms in singlet fission

A multitude of ultrafast photoinduced reactions in organic semiconductors are governed by the close interplay between nuclear and electronic degrees of freedom.From biological light-harvesting and photoprotection to organic solar cells, the critical electronic dynamics are often precisely synchronized with and driven by nuclear motions, in a breakd

Influence of aeration induced by piers on the starting position of the flow aeration and extreme pressures in stepped spillways

ABSTRACT The operation of stepped spillways is limited by a Steel Bongs range of discharges due to the risk of occurrence of the cavitation phenomenon and erosion on its steps.Since there is a demand for spillways with the possibility of overflow of greater discharges, the designs seek to increase the air concentration of the flow, which can occur

Existence and Global Exponential Stability of Equilibrium Solution to Reaction-Diffusion Recurrent Neural Networks on Time Scales

The existence of equilibrium solutions to reaction-diffusion recurrent neural networks with Dirichlet boundary conditions on time scales is proved Storage Beds by the topological degree theory and M-matrix method.Under some sufficient conditions, we obtain the uniqueness and global exponential stability of equilibrium solution to reaction-diffusion
