In alpine terrain, snow sublimation represents an important component of the winter moisture budget, representing a proportion of precipitation which does not contribute to melt. To quantify its amount we analyze the spatial pattern of snow sublimation at the ground, from a canopy and from turbulent suspension during wind-induced snow transport for a high(More)
Liquid-core capsules of high mechanical stability open up for many solid state-like applications where functionality depending on liquid mobility is vital. Herein, a novel concept for fast and facile improvement of the mechanical properties of walls of liquid-core capsules is reported. By imitating nature's own way of enhancing the mechanical properties in(More)
We validate the nonspherical grafting arrangement of isotropically coated spherical nanoparticles as very recently proposed. We utilize localized surface plasmon resonance enhanced dynamic polarized and depolarized light scattering from Au nanoparticles, the spherical symmetry of which was revealed by single-particle dark-field spectroscopy. The same Au(More)

Two new triterpenoid saponins, 3-O-{[beta-D-glucopyranosyl-(1-->2)]-[alpha-L-arabinopyranosyl-(1- ->3)]- alpha-L-arabinopyranosyl}-ursolic acid-28-O-[beta-D-glucopyranosyl] ester (indicasaponin A), 3-O-{[beta-D-glucopyranosyl-(1-->2)]-[alpha-L-arabinopyranosyl-(1- ->3)]- alpha-L-arabinopyranosyl}-oleanolic acid-28-O-[beta-D-glucopyranosyl] ester(More)
The influence of the triterpenoid saponins 1-10 has been investigated on murine spleenocytes in the lymphocyte transformation test and on murine macrophages in an phagocytosis assay. The lymphocyte transformation test and the phagocytosis assay showed that the tested compounds have no stimulating effect. However, a significant inhibition of lymphocyte(More)
