Summary: The interaction mechanism between bovine serum albumin (BSA) and tannic acid (TA) was investigated using spectroscopic and computational approaches, and validated by circular dichroism (CD), differential scanning calorimetry (DSC), and molecular docking techniques. The fluorescence spectra and molecular docking results indicated that TA bound to BSA and caused static quenching at a single binding site. The interaction between BSA and TA was dose-dependent. Thermodynamic analysis showed that hydrophobic forces played a dominant role in the BSA-TA interaction. The stability of the BSA-TA complex was enhanced, as evidenced by changes in secondary structure and increased melting temperature and enthalpy.

Summary: Sulfonamides like sulfametoxydiazine (SMD) and sulfamonomethoxine (SMM) were found to bind to human serum albumin (HSA) through hydrogen bonding and van der Waals forces, with SMD showing stronger binding affinity than SMM. The interaction induced conformational changes in HSA, particularly affecting the alpha-helix content, and specific amino acid residues in HSA were identified as key players in the binding process of sulfonamides. Results suggest that hydrogen bonds play a crucial role in the binding affinity between sulfa drugs and HSA, with combined use of SMD and SMM leading to significant variations in binding constants.

Summary: The interaction between lutein dipalmitate and BSA was found to be static with a binding stoichiometry of 1:1. Thermodynamic study and molecular docking confirmed that lutein dipalmitate spontaneously bound to BSA through hydrogen bonds, van der Waals forces, and hydrophobic interactions. The addition of lutein dipalmitate led to a decrease in the alpha-helix content of BSA, as observed through CD analysis.

Summary: This study investigates the interaction between the sodium channel blocker amiloride and human serum albumin. The results show that amiloride specifically binds to a specific site on HSA and the complex is stabilized by van der Waals hydrogen-bonding and hydrophobic interactions. FRET analysis demonstrates that the distance between amiloride and Trp214 is crucial for efficient quenching. UV-Vis spectroscopy and circular dichroism indicate minor structural changes in HSA after binding. Molecular dynamics simulations provide further evidence of stable HSA-AML complex formation.

Summary: In this study, we address the issue of polymorph selection by introducing a general concept based on ordering. We demonstrate the concept by patterning four compounds on surfaces, which are capable of forming different polymorphs. Our approach takes advantage of the confinement of crystalline material growth within small cavities to generate only one polymorph. We verify our method by fabricating micrometric logic patterns using model compounds, where each printed pixel comprises only one polymorph and can be accessed individually.

Summary: This study evaluates the efficacy of chemo-releasing and photoactive bimodal nanoparticles, kPCe6 NPs, delivered via mesenchymal stromal cells (MSCs). In vitro analyses demonstrated that cells internalize and retain kPCe6 NPs in a dose-dependent manner, and kPCe6-loaded cells induce massive tumor cell death in a tridimensional tumor model. However, when peritumoral administration of two doses containing 10(6) loaded cells was performed in an in vivo OS murine model, there was negligible tumor cell death.

Summary: Rubbing was used on thiophene-based organic semiconductor thin films to induce reversible mechanical amorphisation, which is associated with fluorescence switching regulated by the film's polymorphic nature. Thermal annealing of the films produced an opposite effect, inducing film crystallization starting at a low temperature and generating a stable polymorph at high temperatures in the bulk. The mechanism of mechanical transformation was explained considering the material's mechanical properties and demonstrated through X-ray diffraction, atomic force microscopy, and photoluminescence at confocal microscopy.

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.
