Ceramic nanostructure materials, membranes and composite layers [PDF]
, 1989 Synthesis methods to obtain nanoscale materials will be briefly discussed with a focus on sol-gel methods. Three types of nanoscale composites (powders, membranes and ion implanted layers) will be discussed and exemplified with recent original research ...

Graphitized Carbon Xerogels for Lithium-Ion Batteries [PDF]
Materials, 2019 Carbon xerogels with different macropore sizes and degrees of graphitization were evaluated as electrodes in lithium-ion batteries. It was found that pore structure of the xerogels has a marked effect on the degree of graphitization of the final carbons.

Effects of aerogel-like disorder on the critical behavior of O(m)-vector models. Recent simulations and experimental evidences [PDF]
, 2006 We review some results on the effect of a specific type of quenched disorder on well known O(m)-vector models in three dimension. Evidences of changes of criticality in both systems, when confined in aerogel pores, are briefly referenced. The 3DXY model (

Trapping a Metastable Node in an Amorphous Metal–Organic Framework
Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.
