Bioinspired Hierarchically Interconnected Supermacroporous Hydrogels via Dual‐Templating for Rapid Atmospheric Water Harvesting

Advanced Functional Materials, EarlyView.
Inspired by lung alveolar architecture, a dual‐templating strategy combining CO2 bubble and ice templating creates mechanically robust super‐macroporous hydrogels with highly interconnected transport pathways. The resulting material achieves 3.37× faster moisture sorption and 1.72× higher solar‐driven water release than single‐templated counterparts ...

[Marginal leakage in dental restorations].

Avances en odontoestomatologia, 1990
We make a review of the factors contributing to microleakage around dental restorations and the biological effects that this produces. We also make an evaluation of the existing methods for its research. We analize the behaviour of the different restorative materials, in relation to microleakage, and we set the rules to minimize this inevitable event ...
