Zeaxanthin (Zea) is a key component in the energy-dependent, rapidly reversible, nonphotochemical quenching process (qE) that regulates photosynthetic light harvesting. Previous transient absorption (TA) studies suggested Zea can participate direct via chlorophyll (Chl) to energy transfer. However, contamination of intrinsic exciton–exciton annihilation (EEA) makes assignment TA signal ambiguous. In this study, we present EEA-free data using Nicotiana benthamiana thylakoid membranes,...
Photosynthesis converts solar energy into chemical through coordinated transfer between light-harvesting complexes and reaction centers (RCs). Understanding exciton motion, particularly the diffusion length, is essential for optimizing efficiency in photosystems. In this work, we combine intensity-cycling transient absorption spectroscopy with kinetic Monte Carlo (kMC) simulation to investigate motion C2S2 photosystem II supercomplex of spinach. Using exciton–exciton annihilation, revealed...
A combination of ultrafast, long-range, and low-loss excitation energy transfer from the photoreceptor location to a functionally active site is essential for cost-effective polymeric semiconductors. Delocalized electronic wavefunctions along π-conjugated polymer (CP) backbone can enable efficient intrachain transport, while interchain transport generally thought slow lossy due weak chain–chain interactions. In contrast conventional strategy mitigating structural disorder, amorphous layers...
Incorporating membrane proteins into mimicking systems is an essential process for biophysical studies and structure determination. Monodisperse lipid nanodiscs have been found to be a suitable tool, as they provide near-native bilayer environment. Recently, covalently circularized nanodisc (cND) assembled with scaffold protein (MSP) in circular form, instead of conventional linear has emerged. Covalently shown improved stability, however the optimal strategies incorporation proteins, well...
We report the lipid-composition dependent photocycle kinetics and proton pump activity of bacteriorhodopsin (bR) embedded in nanodiscs composed different lipids.
The moving boundary truncated grid method is developed to significantly reduce the number of points required for wave packet propagation. time-dependent Schrödinger equation (TDSE) and imaginary time (ITSE) are integrated using an adaptive algorithm which economizes points. This employs a variable in Eulerian frame (grid fixed space) adaptively defines boundaries grid. first applied integration TDSE photodissociation dynamics NOCl three-dimensional quantum barrier scattering problem....
The moving boundary truncated grid (TG) method, previously developed to integrate the time-dependent Schrödinger equation and imaginary time equation, is extended evolution of distribution functions in phase space. A variable number space points Eulerian representation are used motion for function, boundaries TG adaptively determined as function evolves time. Appropriate activated deactivated propagation no advance information concerning dynamics required. method equations functions,...
Abstract The moving boundary truncated grid (TG) method is used to study wave packet dynamics of multidimensional quantum systems. As time evolves, appropriate Eulerian points required for propagating a are activated and deactivated with no advance information about the dynamics. This applied Henon‐Heiles potential barrier scattering in two, three, four dimensions. Computational results demonstrate that TG not only leads great reduction number needed perform accurate calculations but also...
It is known that there also a topological phase in the SSH coupled-spring system with fixed-end boundary conditions. When this case, would exist edge modes on its boundaries. In contrast, if satisfies free-end conditions, no mode, even it phase. We show by varying force constant of spring such system, generally appear independent whether bulk or trivial phases. Moreover, could
Abstract Zeaxanthin (Zea) is a key component in the energy-dependent, rapidly reversible, non-photochemical quenching process (qE) that regulates photosynthetic light harvesting. Previous transient absorption (TA) studies suggested Zea can participate direct via Chlorophyll (Chl) to energy transfer. However, contamination of intrinsic exciton-exciton annihilation (EEA) makes assignment TA signal ambiguous. In this study, we present EEA-free data using Nicotiana benthamiana thylakoid...
ABSTRACT Non-photochemical quenching (NPQ) protects photosynthetic organisms via diverse molecular players contributing at varying timescales. However, in the absence of one largest contributors to NPQ, energy-dependent (qE), we observe an unusual but universal phenomenon: a transient increase dark following high light exposure. To mechanistically interrogate this light-to-dark (LtD) NPQ phenotype, performed chlorophyll fluorescence lifetime snapshot measurements across array Arabidopsis...

This paper proposes a novel nanosensing platform for protein fluorescence enhancement by nano ring gap (NRG) induced localized surface plasma resonance (LSPR). On this platform, gold nanoparticles (GNPs) surrounded silver sheathes with nanosized were designed and successfully fabricated immobilization/detection. Through simulation, when the between sheath nanoparticle reduced to 15 nm, light intensity can be enhanced around 8.5 folds of magnitude than that 5 nm sensor. Experiment result has...
