Solute-solvent intermolecular photoinduced electron transfer (ET) reaction was proposed to account for the drastic fluorescence quenching behaviors of oxazine 750 (OX750) chromophore in protic alcoholic solvents. According our theoretical calculations hydrogen-bonded OX750-(alcohol)(n) complexes using time-dependent density functional theory (TDDFT) method, we demonstrated that ET takes place from solvents and passing through site-specific hydrogen bonds exhibits an unambiguous site...

Low-dimensional organic–inorganic hybrid metal halides, with broadband luminescence, have attracted much attention for optoelectronic applications due to their rich in structural diversity and solution processibility. However, it is still unclear about how the solvent molecules influence properties of processed low-dimensional halides.

In the present work, excited-state double proton transfer (ESDPT) in 2-aminopyridine (2AP)/acid systems has been reconsidered using combined experimental and theoretical methods. The steady-state absorption fluorescence spectra of 2AP different acids, such as formic acid, acetic propionic etc. have measured. We demonstrated for first time that ESDPT reaction can take place between all these acids due to formation intermolecular hydrogen bonds. Furthermore, vitally important role bonds also...
Experimental and theoretical methods were used to study newly synthesized thiophene-pi-conjugated donor-acceptor compounds, which found exhibit efficient intramolecular charge-transfer emission in polar solvents with relatively large Stokes shifts strong solvatochromism.

We that charge transfer systems is significantly dependent electron-withdrawing...
In lithium-ion secondary batteries research, binders have received the least attention, although electrochemical performance of Li-ion such as specific capacity and cycle life cannot be achieved if adhesion strengths between electrode particles films current collectors are insufficient to endure charge-discharge cycling. this paper, roles in mechanical integrity electrodes for were studied by coupled microscratch digital image correlation (DIC) techniques. A based composite model was...

Currently, Lithium-ion batteries (LiB) are widely applied in energy storage devices smart grids and electric vehicles. The state of charge (SOC) is an indication the available battery capacity, one most important factors that should be monitored to optimize LiB’s performance improve its lifetime. However, because SOC relies on many nonlinear factors, it difficult estimate accurately. This paper presented design effective estimation method for a LiB pack Battery Management System (BMS) based...
Although a large number of fluorescein derivatives have been developed and applied in many different fields, the general mechanisms for tuning fluorescence still remain uncovered. Herein, we found that quenching neutral form acidic medium resulted from dark nπ* state, whereas anionic gas phase alkaline solutions was tuned by minimal energy conical intersection (MECI). The formation MECI involved significant rotation benzene ring flip-flop motion xanthene moiety, which would be restricted...
