Abstract In the paper presented are studies on the investigation of the capillary forces effect induced in the porous structure of a loop heat pipe using water and ethanol ad test fluids. The potential application of such effect is for example in the evaporator of the domestic micro-CHP unit, where the reduction of pumping power could be obtained. Preliminary analysis of the results indicates water as having the best potential for developing the capillary effect.

Collagen Lattices

A simple technique is described for the preparation of collagen substrata containing 0 1% of collagen by weight, in the form of native bundles with a 640 A period, the substrata are similar in these respects to soft-tissue matrices These substrate are hydrated collagen lattices (HCLs) in which the watery milieu is held within a fibrous collagen net mainly by capillary forces. HCLs have been characterized in terms of the course of collagen precipitation and aggregation, ultrastructure, and their stability under various conditions. The ways in which HCLs can be employed as both two- and three-dimensional substrata in cell behavioral studies are illustrated with some preliminary observations on the form, motility, adhesion, and growth of human diploid cells and two lines of malignant cells.

Diatoms are microalgae organisms that have a cover of silica, with a fascinating ordered porous structure that varies in size, giving them some different characteristics. Because of their different size, shape, and structure, it has incredible properties, letting them be capable of been functionalized with other particles. Therefore, due to the ordered pore structure, the high surface area, biocompatibility, availability, and low processing cost, they present a growing potential for drug delivery when talking about silica materials, natural and synthetic, not to mention that is less expensive and a green alternative.

We report the formation of self-organized porous ZrO2 layers by anodization of Zr in H2SO4 electrolytes. Anodization at 20 V after a potential sweep from open-circuit potential with a defined sweep rate results in tube-like porous ZrO2. In particular, under optimized electrolyte condition and polarization, a highly ordered porous structure is obtained. Furthermore, sponge-like porous ZrO2 is also fabricated under a specific electrochemical condition.
