Local mean-field study of capillary condensation in silica aerogels

open access: yes, 2003
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.

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

open access: yesSmall, 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 ...

Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

open access: yesSmall, EarlyView.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Silica-Resorcinol-Formaldehyde Aerogels Nanostructure Modelling

open access: yesChemical 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.

A new anti-neutrino detection technique based on positronium tagging with plastic scintillators

open access: yes, 2015
The main signature for anti-neutrino detection in reactor and geo-neutrino experiments based on scintillators is provided by the space-time coincidence of positron and neutron produced in the Inverse Beta Decay reaction.

Smart NIR‐Emitting Organometallo Pt(II)‐Ionosilica Aerogel for Selective Au(III) Sensing and Recovery

open access: yesSmall, EarlyView.
This study reports a near‐infrared emitting ionic aerogel composed of cationic cyclometalated Pt(II) moieties linked by Si─O─Si bonds. The resulting porous hybrid material enables the selective detection and recovery of Au(III) ions from mixed‐metal solutions. Owing to its reversible luminescent response and thiourea‐assisted gold recovery, the aerogel
