A theoretical study of sound transmission loss across a simply supported double-composite sandwich plate filled with poroplastic material is formulated. Biot's theory is employed to describe wave propagation in elastic porous media. The two face composite plates are modeled as classical thin plates. By using the modal superposition theory, a double series solution for the sound transmission loss of the structure is obtained with the help of the Galerkin method.

This research investigates the effect of cobalt precursor and calcination time on the morphology and catalytic activity of Co3O4 films in the oxygen evolution reaction (OER). Co3O4 films with porous flower-like nanostructures were obtained using cobalt nitrate as a cobalt precursor, while cobalt chlorides were used to produce porous nanoneedle structures Co3O4 film.

Ebook "Lanthanide metal-organic frameworks" consists of two keywords, “lanthanide” and “metal-organic frameworks”, both of which are among the most active fields of research in chemistry and material science. In comparison with other types of metal ions, lanthanide ions exhibit a large atomic magnetic moment, strong spin-orbital coupling, high coordination number, and abundant coordination modes originating from their unique 4f electronic configurations.

In ebook "Inorganic 3D structures (Structure and bonding, Volume 138)" the reader will find a topical account of examples illustrating WMS’s conjecture (Fe5Si3/Ca5P3) which when taken together define a General Principle which has considerable predictive utility. In Chap. 1, Santamarı´a-Pe´rez and Liebau report the elegant relationships between intermetallic clathrates, porous tectosilicates, and clathrate hydrates, thus completing the huge task of putting the structures of the whole silicate family under a common basis, which was initiated some years ago.

Ebook "Modelling water flow in unsaturated porous media: Accounting for nonlinear permeability and material heterogeneity" focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure.

Porous sunshade roof cover sheets installed on building roofs are new structures for mitigating heat absorption. Thus, there have been few studies on wind flow and its effects on windpermeable structures, and there is no provision for these structures in the major international wind load standards and codes.

Bioinspired structures are remarkable porous structures with great strengthto-weight ratios. Hence, they have been applied in various fields including biomedical, transportation, and aerospace materials, etc. Recent studies have shown the significant impact of the plastic 3D printed triply periodic minimal surfaces (TPMS) structure on the cement beam including increasing the peak load, reducing the deflection, and improving the ductility.

Positron annihilation is of great interest for applications in evaluating material structures in range from a few angstroms to hundreds of nanometers. Here, we report on a new model for calculating the free volume size in porous materials from the experimental ortho-Positronium (o-Ps) lifetimes reported and updated over than past four decades by the combination of the quantum and semi-classical physics models.

Carbon aerogels prepared from resorcinol formaldehyde organic aerogels have a wide range of use due to their considerably large specific surface area. Since the applications mostly happen in wet form, e.g. in aqueous medium, NMR cryoporometry was employed to follow the porous behavior of an organic aerogel and its carbon derivative, as well as the textural changes after the pyrolysis.
