The adsorption geometry of the planar 3, 4, 9, 10-perylene-tetracarboxylic-dianhydride (PTCDA) moleculein the commensurate c(8 × 8) structure on Ag(100) was determined from the analysis of the intensities in low-energy electron diffraction (LEED-IV). Using data from different angles of incidence and optimized computercode, we were able to overcome earlier challenges given by the limitations of the experimental data set and thecalculation times required for the large unit cell with many atoms.

In this study, we examine the Soret effect of ammonium chloride (NH4Cl) and its alkyl-substitutedderivatives: dimethylammonium chloride (DMACl), ethylammonium chloride (EACl), and trimethylammoniumchloride (TMACl) in aqueous solution using infrared thermal diffusion forced Rayleigh scattering.The Soret coefficient, ST, increases systematically with alkyl substitution, following the trend NH4Cl <<DMACl < EACl << TMACl, while hydrophilicity decreases correspondingly. Across the investigated temperaturerange (15−45◦C) and concentrations (1–4 mol/kg), ST increases with both temperature andthe degree of alkyl substitution [...]

The all-D-enantiomeric-peptide RD2 was developed for the treatment of Alzheimer’s disease. This study aimed to develop a specific and highly sensitive liquid chromatographymass-spectrometric (UHPLC-ESI-QTOF) method for quantifying RD2 in the mouse brainand to validate it according to the ICH M10 guideline to investigate the pharmacokinetic profile of RD2 in its target organ.
