Résistance d'un milieu poreux à phase solide hétérogène

Comptes Rendus. Mécanique, 2005
On s'intéresse au critère de rupture macroscopique d'un matériau poreux dont la phase solide est constituée d'un ensemble de sphères composites formées d'un noyau infiniment résistant entouré d'une calotte dont la rupture est caractérisée par un critère de von Mises.

Iron‐MOFs for Biomedical Applications

Advanced Healthcare Materials, Volume 14, Issue 8, March 25, 2025.
This review introduces the unique properties of iron‐based metal–organic frameworks (Fe‐MOFs), the advances in synthesis and formulation, and their state‐of‐the‐art applications in biomedicine. It discusses the challenges in transitioning Fe‐MOFs from research to clinical use, emphasizing the need for eco‐friendly production methods, and a deeper ...

Embracing uncertainty: porous and actionable responses to climate change at the borders of Indigenous and scientific expertise(s) in Siberia

Journal of the Royal Anthropological Institute, Volume 31, Issue 1, Page 63-81, March 2025.
Abstract This article explores uncertainty as an onto‐epistemological concept that reveals integrative capacities of Indigenous and scientific knowledge. Looking at official scientific approaches to climate change in Russia, it traces how Indigenous peoples in Siberia navigate their lives as they continue to witness anthropogenic causes of climatic ...

Radial Fingering in a Porous Medium Digitation radiale dans un milieu poreux

Oil & Gas Science and Technology, 2006
The theory of immiscible radial displacement in a Hele-Shaw cell is extended to the case of a porous medium contained between two closely-spaced parallel plates, and experiments are described for the displacement of glycerine by paraffin oil in such a ...

Ultra‐Microporous Fe‐MOF with Prolonged NO Delivery in Biological Media for Therapeutic Application

Small, Volume 20, Issue 48, November 27, 2024.
New ultra‐narrow pores iron bisphosphonate MOF (MIP‐210) with outstanding properties for an unprecedent controlled release of a potential gaseous therapeutic agent ‐ nitric oxide (NO). The unique adsorption mechanism, along with the MOF's high chemical stability and narrow pores, leads to an extended NO delivery time exceeding 70 h in biological media.

Poroelasticity and Poroplasticity At Large Strains Poroélasticité et poro-élastoplasticité en grandes déformations

Oil & Gas Science and Technology, 2006
This paper reviews some aspects of the formulation of the constitutive behavior of a saturated porous material in isothermal evolutions in the domain of large strains. First, the results concerning the nonporous solid are recalled.

Water Fingering Into an Oil-Wet Porous Medium Saturated with Oil At Connate Water Saturation Digitation de l'eau dans un milieu poreux mouillable à l'huile saturée en eau connée

Oil & Gas Science and Technology, 2006
The effect that connate water has on fingers of water penetrating into an oil-wet porous medium is examined. In this context, the connate water appears to have no influence on the width of fingers, but instead causes the fingers to be more irregular than
