The photocatalytic activity of TiO2–SiO2-coated cotton textiles was investigated through the self-cleaning of red wine stains. It was shown that a TiO2–SiO2 species could be produced at temperatures of 100 °C with acceptable photo-activity on non-heat resi ...
The authors measured the ultrafast response of triangular silver nanoparticles upon femtosecond excitation of their plasmon resonance. After a fast electron relaxation, the signature of a bimodal mech. vibration of the particle is apparent as a spectral mo ...
The structure and the associated dynamics of a series of poly(?-benzyl-L-glutamate)-b-poly(dimethyl siloxane)-b-poly(?-benzyl-L-glutamate) (PBLG-b-PDMS-b-PBLG) triblock copolymers were investigated using small- and wide-angle X-ray scattering, NMR, transmi ...
Wurtzite GaN/AlN quantum dots (QDs) are studied by time-resolved photoluminescence. Careful measurements allow us to reach the regime of a single electron-hole pair per dot, evidenced by a monoexponential decay of the luminescence and a stop of the time-de ...
Permeable reactive barriers employing iron as a reactive surface have received extensive attention. A remaining issue, however, relates to their longevity. As an integral part of a long-term column study conducted to examine the influence of inorganic coso ...
Femtosecond transient absorption spectroscopy has been used to investigate the electron-electron scattering dynamics in sulfate-covered gold nanoparticles of 2.5 and 9.2 nm in diameter. We observe an unexpected retardation of the absolute internal thermali ...
The bacterial inactivation of Escherichia coli on Ag–cotton textiles were investigated under different experimental conditions with novel Ag-nanoparticles fixed on cotton textiles. The evaluation of the bactericide performance of the Ag–cotton was compared ...
Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...
Hydrogen atoms introduced into a bulk of rare earth-transition metal compound influence the electronic structure of the material. Additional electrons are expected to change the number of free electrons per volume unit present in the system. Electron energ ...
The biogeochemical alteration of an Mg-Fe orthopyroxene, reacted for 70 yr under and conditions in a desert environment, was Studied by transmission electron microscopy. For this purpose, an electron transparent cross-section of the interface between a sin ...
