Band Formation during Gaseous Diffusion in Aerogels
We study experimentally how gaseous HCl and NH_3 diffuse from opposite sides of and react in silica aerogel rods with porosity of 92 % and average pore size of about 50 nm.

Helium condensation in aerogel: avalanches and disorder-induced phase transition
We present a detailed numerical study of the elementary condensation events (avalanches) associated to the adsorption of $^4$He in silica aerogels. We use a coarse-grained lattice-gas description and determine the nonequilibrium behavior of the adsorbed ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Local mean-field study of capillary condensation in silica aerogels
We apply local mean-field (i.e. density functional) theory to a lattice model of a fluid in contact with a dilute, disordered gel network. The gel structure is described by a diffusion-limited cluster aggregation model.

Photoreforming of methanol is followed in real time by solid‐state Magic Angle Spinning NMR. The transparent sapphire sample holder is irradiated by four LEDs at 11.5 kHz MAS. Efficient light penetration into the sample volume is ensured by silica monoliths with a network of macropores, coated with TiO2, and enhancing light penetration by a factor of ...
