Long-term response of soils subjected to repetitive geoenvironmental loads
… microfluidic chips provides new insight into salt crystallization phenomena in geomaterials, such as fractured rocks. Deformable PDMS captures the effect of the crystallization force. Pore network topology and surface wetting characteristics govern crystal growth patterns. Pore fluid chemistry …

Superhydrophobic membranes for membrane distillation and crystallization
… lower operating temperature and pressures, high salt rejection and the ability to process high concentration feeds. However, inefficiencies exist in the form of low permeate flux and membrane wetting. Superhydrophobic modifications to the membrane surface could potentially overcome this issue. …

Titania-silica composite materials for self-cleaning applications on monumental stones
… they substantially improve protection against salt crystallization degradation processes. By using of N2 physisorption, atomic force microscopy and electron tomography, together with 3D reconstructions, we have been able to conclude that the texture of the nanocomposites synthesized is a key …

Chirale ionische Flüssigkeiten in der homogenen Katalyse
… hereby was the efficient synthesis of pure salts and the expansion of the synthesis to new, structurally related ILs. In doing so two different categories of chiral ILs were examined. Starting with L-(-)-malic acid an anionchiral IL with a borate structure was synthesized. The optimization …

Assessment of salt decay in granite masonry: experimental and numerical approaches
A cristalização de sais é um dos mecanismos de deterioração que mais afetam materiais de construção porosos, especialmente em estruturas de alvenaria de valor histórico e cultural. Embora exista uma vasta investigação sobre a cristalização de sais em materiais porosos, menor atenção tem sido dada a …
