The zero temperature adsorption isotherm of 4He in a rigid cylindrical pore with alkali metal walls is computed within finite-range density functional theory, with the radius of the tube as a parameter. It is shown that ...

The adsorption potential in the interior of an infinite nanopore along the z-axis, with varying radius R(z), is derived as a function of a deformation parameter. Detailed calculations for a carbon nanotube indicate that ...

We examine the metastable and unstable regimes of condensation of superfluid helium and parahydrogen on spheres and cylinders at finite temperatures, employing finite range density functionals. The goal is to compare ...

We investigate adsorption of helium in nanoscopic polygonal pores at zero temperature using a finite-range density functional theory. The adsorption potential is computed by means of a technique denoted as the elementary ...

The adsorption of helium on spherical cavities is investigated employing finite range density functional theory. It is known that for films outside spherical walls, a growth instability occurs above a critical film thickness. ...

We investigate the adsorption of helium in alkali wedges at zero temperature within a fully unrestricted density--functional theory. We have found a sequence of shapes that includes one filling transition on the nonwettable ...

We  report studies of adsorption of helium in <br />translationally invariant polygonal<br />pores at zero temperature, with emphasis on the route to capillary <br />condensation and the appearance of <br />metastable ...

Water pollution by emerging contaminants such as pharmaceuticals has gained interest in recent years. These drugs have great potential in generating adverse effects for human and wildlife, since they are endocrine ...

In this work we report results of NOx adsorption and diesel soot combustion on a noble metal promoted K/La2O3 catalyst. The fresh-unpromoted solid is a complex mixture of hydroxide and carbonate compounds, but the addition ...
