Structural and optical characteristics of manganese doped cadmium sulfide nanoparticles prepared by <italic>in situ</italic> chemical synthesis using biocompatible Na-alginate biopolymer as a template is reported.
Proline is a unique amino-acid, with secondary amine fixed within pyrrolidine ring providing specific structural properties to proline-rich biopolymers. Gas-phase proline possesses four main H-bond stabilized conformers differing by the puckering and carboxylic acid orientation. The latter defines two classes of conformation, whose large ionization energy difference allows conformer-class tagging via electron spectroscopy. Photoelectron circular dichroism (PECD) an intense chiroptical effect...
Spherical shaped nanoparticles of series Y2 − xEuxO3 (x = 0.06, 0.10, 0.20, and 2) Gd2 0.10) were prepared by thermolysis 2,4-pentanedione complexes Y, Gd, Eu. The bixbyite phase samples was formed at 500 °C, whereas the thermal decomposition Y Eu complexes' mixtures occurred higher temperatures. Linearity in concentration dependence on lattice parameter confirmed formation solid solutions. distribution Eu3 + changed with annealing: as-prepared sample preferential C3i sites while annealed...
Hybrid nanosystems composed of glycogen biopolymers and gold nanoparticles were prepared by an in situ non-toxic synthetic procedure. Transmission electron microscopy (TEM) various spectroscopic methods (optical absorption, X-ray photoelectron photoluminescence spectroscopy) used for the characterization obtained bioconjugates. The formed presence spherical shape approximately 15 nm diameter. TEM micrographs show that aggregated on surface biomolecules. This effect induced a shift plasmon...
Structural changes at the molecular level, occurring onset of condensation, can be probed by angle-resolved valence photoelectron spectroscopy, which is inherently sensitive to electronic structure. For larger condensed systems like aerosol particles, observation intrinsic angular anisotropies in photoemission (β parameters) challenging due strong reduction their magnitude electron transport effects. Here, we use a less common, more observable form chiral asymmetry parameter perform...

Biological entities, such as DNA bases or proteins, possess numerous tautomers and isomers that lie close in energy, making the experimental characterization of a unique tautomer challenging. We apply VUV synchrotron-based experiments combined with state-of-the-art ab initio methodology to determine adiabatic ionization energies (AIEs) specific gas-phase cytosine produced molecular beam. The structures energetics neutral cationic were determined using explicitly correlated methods. spectra...
Photoelectron circular dichroism (PECD) is an intense orbital-specific chiroptical effect observed as asymmetries in the angular distribution of photoelectrons produced by photoionization randomly oriented pure enantiomers with circularly polarized light. After a broad introduction placing this context new physical chiral-sensitive methods, we review main characteristics PECD terms molecular dynamics. We stress also analytical capabilities to retrieve enantiomeric excesses (e.es.) and probe...
