Titanium Dioxide Induced Immobilization of Small Platinum Nanoparticles on Carbon Spherogels: A Strategy Towards Stable and Efficient Electrocatalysts for the Hydrogen Evolution Reaction

Small, EarlyView.
Platinum nanoparticles are immobilized on hollow carbon spherogels using supercritical deposition, enabling precise control over nanoparticle size, loading, and spatial distribution. Incorporation of an internal TiO2 sublayer in the hollow sphere support induces enhanced metal–support interactions, markedly improving hydrogen evolution activity and ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
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

Optical shock waves in silica aerogel

Optics Express, 2014
Silica aerogels are materials well suited for high power nonlinear optical applications. In such regime, the non-trivial thermal properties may give rise to the generation of optical shock waves, which are also affected by the structural disorder due to the porous solid-state gel.

Silica-Resorcinol-Formaldehyde Aerogels Nanostructure Modelling

Chemical Engineering Transactions, 2018
The work is devoted to the study and modelling of the internal nanostructure of silica-resorcinol-formaldehyde aerogels. These aerogels are highly porous (up to 98 %) functional materials with a high specific surface area, low thermal conductivity, and good sound insulation.
