Summary: The coordination-state dependency of the excited-state properties and ultrafast relaxation dynamics from the S2 to the S1 state of bacteriochlorophyll a were investigated using quantum chemical calculations and nonadiabatic molecular dynamics simulations. The results revealed the molecular mechanism of excitation energy difference decrease caused by ligand coordination and demonstrated the acceleration of relaxation by the ligand. The study highlighted the significance of environmental effects in relaxation dynamics, which have not been previously explored theoretically.

Summary: This study quantitatively assesses a dynamic method for calculating thermally averaged electronic excitation energies in linear polyene molecular systems. The results suggest that the static approach is sufficient for modeling polyenes with fewer than 50 carbon atoms, but considering thermal motions is recommended for longer polyenes.

Summary: A semi-empirical model was developed to reproduce ab initio excitation energies and UV-Vis absorption spectra for nanoclusters. The model, oeINDO, achieved good agreement with EOM-CCSD and TDDFT spectra, with low mean absolute errors. It showed potential for predicting absorption spectra of nano-sized clusters and their suitability for solar cell applications.

Summary: Different metal oxide nanoparticles were synthesized using sonochemical treatment and combustion, and utilized as supports for palladium catalysts. The Pd/NiFe2O4 catalyst showed the highest TDA yield of 99%, followed by the Pd/CoFe2O4 catalyst with 84.2%. The complete recovery of the catalyst from the reaction medium is facilitated by the full magnetic properties of the ferrite support.

Summary: In this study, a star-shaped giant trimer (G-Trimer) is reported for the fabrication of organic solar cells with high efficiency, long-term stability, and scalability using o-xylene. It shows great potential as a commercial photovoltaic material compared to linear-shaped dimers and polymers. The unique star-shaped architecture and high molecular weight of G-Trimer result in a temperature-dependent aggregation property and the relaxation of disordered entanglements, leading to a low energetic disorder fibrous morphology in the active layer. This enables long charge lifetime and efficient dual hole-transfer channels under low driving force, resulting in record efficiencies. The device also exhibits a small kinetically trapped morphology with high Tg, giving it a T90 of longer than 4,500 h after continuous heating at 80 degrees C without further decay. These findings provide important guidance for the development of high-performance photovoltaic materials for commercialization.

Summary: We propose a dynamical simulation scheme to study the excited state dynamics of linear polyenes. Using the Hubbard-Peierls model coupled with the nuclear degrees of freedom, we investigate the internal conversion processes of photoexcited carotenoids. By defining adiabatic and diabatic excited states, we present a computational framework to monitor the internal conversion process and calculate transient absorption spectra. Our results demonstrate the accuracy of our method in describing carotenoid excited state dynamics and discuss the effect of symmetry breaking on the internal conversion process.

Summary: MXenes are a class of two-dimensional transition metal carbides, nitrides, and carbonitrides with diverse surface terminations and compositions, which have the potential to advance the development of novel devices. Quantum-mechanical simulations reveal the impact of metal elements and surface terminations on the optical and plasmonic characteristics of M2CTx MXene nanoflakes, showing the formation of localized surface plasmon resonances. The Janus MXene nanoflake Ti2CFO exhibits the strongest and narrowest infrared LSPR due to its large out-of-plane time-dependent dipole moment.

Summary: The development of sustainable energy storage devices is crucial for energy management transformation. Organic batteries have attracted significant attention in this field. To overcome the shortcomings of typical materials, a novel design concept integrating stable radicals within a conductive polymer backbone was introduced. Through theoretical modeling and simulations, the impact of various factors on the battery performance was investigated, leading to the synthesis of two promising candidates for novel organic radical batteries.

Summary: In this work, the rovibrational energy levels of four isotopologues of methylene were calculated using a new accurate ab initio potential energy surface. The accuracy of the calculations was improved by considering scalar relativistic effects, DBOC, and high-order electronic correlations. For the first time, all available experimental rovibrational transitions were reproduced with high accuracy, without any empirical corrections.
