Brønsted acid sites (BAS) in dry aluminosilicate zeolites, also known as bridging O H –H
groups, may form hydrogen bonds with other framework oxygen atoms, O, in addition to BAS …

Based on the concepts of the mechanics of unsaturated soils where capillary phenomena
arise between the wetting fluid (water) and the non-wetting one (air), the subsidence of chalks …

Hydrogen-bonded SiOH defects and Brønsted acidic bridging OH groups, defined as Brønsted
acid sites (BAS), yield overlapping signals in 1 H MAS NMR and FTIR spectroscopies. …

Production of nitric oxide (NO) in endothelial cells is regulated by direct interactions of
endothelial nitric oxide synthase (eNOS) with effector proteins such as Ca 2+ ‐calmodulin, by …

Among some few others tests, the evaluation of the Atterberg limits is a very basic soil mechanical
test allowing a first insight into the chemical reactivity of clays. Basically, the liquid limit …

The effect of outer-sphere environment on alkene epoxidation catalysis using an organic
hydroperoxide oxidant is demonstrated for calix[4]arene-Ti IV single-sites grafted on …

This article presents the results of tests carried out on partially saturated shale samples: a
water retention curve was measured, and the evolutions of mechanical properties (uniaxial …

To better understand the role of reactive Fe (Fe R ) in the preservation of sedimentary
organic carbon (SOC) in estuarine sediments, we examined specific surface area, grain size …

Two pairs of Brønsted acid sites have been identified in H,Na‐Y zeolite, located in the supercage
and in the sodalite cage, which upon ultrastabilization (dealumination) are transformed …

The Winchcombe meteorite is a CM chondrite breccia composed of eight distinct lithological
units plus a cataclastic matrix. The degree of aqueous alteration varies between intensely …
