[EN] Intuitively, a boundary in an N-dimensional digital space is a connected component of the (N − 1)-dimensional surface of a connected object. In this paper we make these concepts precise, and show that the boundaries ...

[EN] Double-layer films, prepared by casting films of xanthan gum (XG), and subsequently poly(vinyl acetate) (PVAc) onto the former, are reported. The resulting XG/PVAc films provide high protection as coatings to a bleaching ...

[EN] The ability to manufacture metamaterials with exotic electromagnetic properties has potential for surprising new applications. Here we report how a specific type of metamaterial-one whose permittivity is near zero-exerts ...

[EN] Fibrinogen (FG) adsorption on surfaces with controlled fraction of -OH groups was investigated with AFM and correlated to the initial interaction of primary endothelial cells (HUVEC). The -OH content was tailored ...

[EN] The importance of the use of geometry in architecture design, and more specifically the use of geometric surfaces that shape the architectural space is this paper focus. The paper sets the value of the use of these ...

[EN] A colonisation process is usually understood as a movement from the inside to the outside, as a porous extension of the frontiers. Colonisation has been however a notion adopted to designate also some inner processes ...

[EN] The potential of oxide-supported rhodium single atom catalysts (SACs) for heterogeneous hydroformylation was investigated both theoretically and experimentally. Using high-level domain-based local-pair natural orbital ...

Protein adsorption and cellular behavior depend strongly on the wettability of substrates. Such studies are scarce for surfaces exhibiting extreme values of contact angles. Fibronectin (FN) adsorption and adhesion of ...

In this work we consider the Taylor expansion of the exponential map of a submanifold immersed in Rn up to order three, in order to introduce the concepts of lateral and frontal deviation. We compute the directions of ...
