Summary: Aqueous electrolytes usually have poor electrochemical stability, but eutectic aqueous solutions containing 25 wt.% LiCl and 62 wt.% H3PO4, cooled to 78 degrees C, show a significantly improved stability. Experimental and simulation results reveal that this improved stability is due to the reduced hydration of Li+ ions, the formation of ice-like water clusters, and the strengthening of H center dot center dot center dot Cl- bonding. Surprisingly, the low-temperature solvation structure does not strengthen water molecules' O-H bond, contrary to conventional wisdom. A proposed mechanism for water's low temperature inertness in the electrolyte is the less favorable solvation of OH and H+, the byproducts of hydrogen and oxygen evolution reactions. An aqueous Li-ion battery using LiMn2O4 cathode and CuSe anode is demonstrated to showcase this stability, with a high energy density of 109 Wh/kg. These findings highlight the potential of aqueous batteries for polar and extraterrestrial missions.

Summary: This study investigated the hydrogen bonding of water and water/salt mixtures around a proline-based tripeptide model using UVRR, revealing the significant roles of cations and fluoride/chloride anions in affecting the conformational stability of proline residues. The spectroscopic data suggested that cations alter the solvation shell at the carbonyl site of proline, while fluoride and chloride ions promote the strongest interactions at the C = O site of proline, leading to greater stabilization of the trans conformers of the tripeptide.

Summary: We conducted an experimental and computational study on the Raman and Resonance Raman spectra of amides in aqueous solution. By using advanced QM/MM methods and synchrotron-based UV Resonance Raman spectroscopy, we developed a protocol to interpret and predict Resonance Raman spectra for amide systems in water. Our findings demonstrate that the experimental spectral features can be accurately reproduced by considering the dynamic aspects of solvation, specific solute-solvent hydrogen bond interactions, and mutual solute-solvent polarization effects.

Summary: The study investigates the dependence of amide I nu(C=O) and the alpha COO- terminal nu(C=O) bands on neighboring side chains, length of the peptide fragment, and extent of intramolecular hydrogen bonding through analysis of the EGEDEA peptide. The results show that the intramolecular charge transfer is dependent on the overall polarity of the fragment, with larger and more polar fragments exhibiting the greatest extent of intramolecular charge transfer. A steady blue shift is observed in the amide I band position as the peptide fragment size increases from ED to EGEDEA.

Summary: In this study, the synthesis and photochemical characterization of a substituted N-BODIPY compound were investigated. Compared to a standard BODIPY, the compound showed a lower fluorescence quantum yield in the visible region. The excited state relaxation dynamics of the dye were studied in different solvents, revealing fluorescence quenching in polar solvents and environment polarity-dependent excited state decay rates. Transient absorption spectroscopy and TD-DFT calculations were used to analyze the involvement of charge transfer states and assign transient signals to specific electronic configurations. The complete picture of N-BODIPY behavior showed the presence of both charge transfer and localized states, influencing photophysics depending on excitation conditions and surrounding environment.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
