The influence of various pH values on the aerogel physical properties by sol-gel technique

Iraqi Journal of Physics, 2019
Hydrophobic silica aerogels were successfully preparation by an ambient pressure drying method from sodium silicate (Na2SiO3) with different pH values (5, 6, 7, 8, 9 and 10). In this study, acidic HCl (1M), a basic NH4OH (1M) were selected as a catalyst

Hydrophobic silica aerogel production at KEK

, 2011
We present herein a characterization of a standard method used at the High Energy Accelerator Research Organization (KEK) to produce hydrophobic silica aerogels and expand this method to obtain a wide range of refractive index (n = 1.006-1.14).

New universality class for the three-dimensional XY model with correlated impurities: Application to $^4$He in aerogels

, 2003
Encouraged by experiments on $^4$He in aerogels, we confine planar spins in the pores of simulated aerogels (diffusion limited cluster-cluster aggregation) in order to study the effect of quenched disorder on the critical behavior of the three ...

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

Small, EarlyView.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

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 ...

Deformed aerogels in the superfluid 3He

, 2015
Deformed aerogels induce a global anisotropy in the superfluid 3He and orient the orbital part of its order parameter. Here a phenomenological theory of the orientational effect of elastic deformations of aerogels on the superfluid phases of 3He in the ...

Additive‐Free Edge‐Functionalized Graphene Dough

Small, EarlyView.
An edge‐functionalized, few‐layer graphene dough, synthesised directly from graphite, provides an additive‐free, processable graphene for moldable and printed electronic and magnetic applications. ABSTRACT The exploitation of graphene's extraordinary properties depends on finding new ways to synthesize and process it without disrupting its fundamental ...

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
