On the Electronic and Optical Properties of Metal-Organic Frameworks: Case Study of MIL-125 and MIL-125-NH2

Berend Smit, Alfredo Pasquarello, Kyriakos Stylianou, Francesco Ambrosio, Gloria Capano, Stavroula Kampouri

The photo-active MIL-125 and MIL-125-NH2 metal-organic frameworks (MOFs), despite having a very similar crystalline structure, exhibit different optical behaviors. Luminescence in MIL-125 decays in about 1 ns, while for its amino counterpart, the lifetime ...

Hydrophobization of silver nanoparticles through surface-initiated atom transfer radical polymerization

Heinrich Hofmann, Frank Nüesch, Jose Enrico Quijano Quinsaat

This work describes the synthesis of poly(methyl methacrylate) (PMMA)-coated Ag@SiO2 core-shell particles by conducting a Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP). Silver nanoparticles (AgNPs) were first prepared by the polyol synth ...

Quantification of Bulk Densification in Fused Silica Induced by Femtosecond Laser Exposure in the Sub-50 fs Regime

Yves Bellouard

Using micro-cantilever deflection, we study laser-induced densification in bulk fused silica in the sub-50 fs, non-ablative regime. We estimate induced densification from deflection measurements, with a maximum value of 0.014%. ...
