Aerogels of 1D Coordination Polymers: From a Non-Porous Metal-Organic Crystal Structure to a Highly Porous Material [PDF]
, 2016 The processing of an originally non- porous 1D coordination polymer as monolithic gel, xerogel and aerogel is reported as an alternative method to obtain novel metal- organic porous materials, conceptually different to conventional crystalline porous ...

Phase transformations in xerogels of mullite composition [PDF]
Monophasic and diphasic xerogels have been prepared as precursors for mullite (3Al2O3-2SiO2). Monophasic xerogel was synthesized from tetraethyl orthosilicate and aluminum nitrate nanohydrate and the diphasic xerogel from colloidal suspension of silica ...

Energy consumption estimation in the scaling-up of microwave heating processes [PDF]
, 2015 The specific energy consumption of six different microwave-driven processes and equipments has been studied and it was found that the scale used dramatically affects it. Increasing the amount of sample employed from 5 to 100 g leads to a reduction in the

Anchoring selenido-carbonyl ruthenium clusters to functionalised silica xerogels
Journal of the Brazilian Chemical Society, 2003 Silica Xerogels containing carbonyl Ru3Se2 nido clusters were prepared in three different ways. The simple dispersion of [Ru3(mu3-Se)2(CO)7(PPh 3)2] via sol gel process produces an inhomogeneous material; by contrast, homogeneous xerogels were obtained ...

Influence of catalyst support characteristics and functionalization on the catalytic activity of Pt-Ru for PEM fuel cells [PDF]
, 2011 Pt-Ru electrocatalysts supported on carbon xerogels and ordered mesoporous carbons were synthesized by reduction with formate ions (SFM method). Chemical and heat treatments were applied to modified the surface chemistry of original carbon supports ...

New hybrid organochlorinated xerogels
, 2021 Hybrid silica xerogels (HSXG) combine the properties of organic and inorganic components in the same material, which makes them promising and versatile candidates for multiple applications. These materials can be easily prepared by the sol-gel process, which offers the possibility to obtain different morphologies.
