That first, they ought to refer matters unto them, which is the first begetting, or impregnation; but when they are elaborate, moulded, and shaped in the womb of their counsel, and grow ripe, and ready to be brought forth, that then they suffer not their counsel to go through with the resolution and direction, as if it depended on them; but take the matter back into their own hands, and make it appear to the world, that the decrees and final directions
Therefore, scC[O.sub.2] is a suitable solvent for impregnation processes [28], e.g.
New GOLLER DYEPADDER ECONOMICA Nip-in-Trough with Double Impregnation Mechanism provides even dyeing for knitted fabric without crease mark and distortion.
Furthermore, the adsorbents prepared by the impregnation method with SiO2 as carrier, CuCl loaded coefficient of 25.0 wt% and calcinated at 400 AdegC showed higher separation effects.
One alternative involves the use of vacuum impregnation.
It has been proved that surface impregnation by water repellent agents should be an effective preventive method for concrete structures [4-9].
Process of supercritical solvent impregnation (SSI) implies dissolution of an additive in supercritical fluid and its subsequent incorporation into a polymer matrix [1, 2] which leads to formation of an added-value polymeric material.
Through this study we propose two synthesis strategies; the first one (impregnation approach) consists in the intimate mixing of already formed and crystalline Co[Fe.sub.2][O.sub.4] nanoparticles, well-dispersed in oil-in-water microemulsion, with amorphous Ti[O.sub.2] nanoparticles, obtained, and contained in a microemulsion system with the same oil-surfactant-water composition; the second one is based on a seed mediated approach, where cobalt ferrite (synthesized by the O/W microemulsion method) is employed as nucleation substrate (seed) for the in situ growing of amorphous Ti[O.sub.2] in a microemulsion reaction system.
The aim of this study is to verify that the 3D printing technology can be used to produce porous monolithic structures of calcium sulphate which can be then activated with commercial Ti[O.sub.2] photocatalyst (Degussa P25) through an impregnation process.
Thanks to the microfilament structure, the impregnation remains stable over the product lifetime to ensure constant liquid release.
