Summary: The delta conformation, a local secondary structure in proteins, is stabilized by specific side-chain/backbone N-H interactions in derivatives of a cyclic amino acid with a sulphur atom in the gamma-position. This allows the delta conformation to compete with classical C5 and C7 hydrogen bonded conformers, expanding the range of small-molecule models beyond rigid proline-type compounds.

Summary: A computational study has rationalized the different phosphorescence colors of two highly emitting crystal polymorphs of a dinuclear Re(I) complex. The electrostatic interactions between the charge distributions on neighboring molecules inside the crystal are responsible for the different stabilization of the emitting triplet state due to the different molecular packing. These self-consistent effects play a major role in the phosphorescence of crystals made of polar and polarizable molecular units, offering a powerful handle to tune the luminescence wavelength in the solid state through supramolecular engineering.

Summary: The phenomenon of excited-state symmetry breaking is often observed in multipolar molecular systems, significantly affecting their photophysical and charge separation behavior. In this study, the intrinsic factors regulating excited-state symmetry breaking in multibranched systems are explored using a combination of experimental and theoretical investigation. It is found that the large Stokes shifts observed in highly symmetric phenyleneethynylenes can be explained by the presence of low-lying dark states, as confirmed by two-photon absorption measurements and TDDFT calculations. In addition, an intense fluorescence emission is observed in these systems contrary to Kasha's rule, and this behavior is explained by a novel phenomenon called symmetry swapping, which describes the inversion of the energy order of excited states as a result of symmetry breaking.

Summary: A new method has been developed to prepare merocyanines, including rhodols, from readily available tetrafluorohydroxybenzaldehyde and aminophenols. This method enables the synthesis of merocyanines with three fluorine atoms and additional conjugated rings under neutral, mild conditions. The transformation of the rhodol chromophore into π-expanded merocyanines allows for the modulation of photophysical properties, such as shifting absorption and emission bands across the visible spectrum, achieving a large Stokes shift, high brightness, strong two-photon absorption, and solvatofluorochromism. Detailed investigation provides insights into the different spectroscopic behavior of rhodols and new merocyanines, including solvatochromism and two-photon absorption.

Summary: Flavonoids in cocoa and derived products can interact with proteins, but this interaction does not affect protein bioaccessibility and digestibility during digestion. The interaction between whey proteins and catechins was evaluated in a model system and commercial milk chocolate. The solubilization, hydrolysis, and peptide profile of proteins were determined using in vitro digestion methods. The slight interaction between flavonoids and proteins did not hinder protein digestion and solubilization. The digestibility of proteins in milk chocolate was found to be complete.

Summary: Three new microporous mixed-ligand MOFs (PUM310, PUM310Me(2), and PUM310CO) were synthesized through solvothermal reactions between bis-pyridine-bis-amide ligands and 2,6-naphthalenedicarboxylic acid. The structural characterization revealed polycatenated frameworks with truncated Zn-paddle wheels, and solvent removal resulted in framework rearrangement and shrinkage. The MOFs exhibited fluorescence in the solid state, and the optical spectra indicated efficient Forster resonance energy transfer (FRET) between the ndca(2-) donor and bis-pyridine acceptors, particularly in PUM310CO.

Summary: We investigated the thermodynamics of protein adsorption on negatively charged colloidal gold nanoparticles (GNPs) at pH 7.0. The protein adsorption on GNPs was found to follow Langmuir-type adsorption isotherms at low protein concentrations, but shifted to BET adsorption isotherms at higher protein concentrations, indicating multilayer formation on the GNP surface. The equilibrium binding constants and monolayer thickness were obtained from the measurements. The size of the GNPs influenced the monolayer binding constant, while the size of the protein did not significantly affect the subsequent layer binding constant. The first layer on the GNP surface was stable but removable by centrifugation, while the subsequent layers were weakly bound. The Gibbs free energy changes indicated that the proteins were physiosorbed on the GNP surface. Temperature-dependent data showed that the protein adsorption on GNPs was endothermic with a large increase in entropy. The BET fits suggested that the multilayer adsorption started before monolayer formation and did not occur in a layer-by-layer sequence.

Summary: Characterization of the nanoparticle protein corona using SHLS revealed that the formation of the GNP-ADH corona is entropically driven. The equilibrium binding constant obtained from SHLS is around 10^9 M^-1, and the process is modestly endothermic with a large increase in entropy. The SHLS technique is highly sensitive and reliable for quantitatively estimating the thermodynamic parameters of nanoparticle-protein corona formation at low concentrations.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
