Polycrystalline materials with crystallite diameters below hundred nanometer exhibit extraordinary strength which goes along with a decrease in ductility. In order to tailor tough materials, which combine strength and ductility, the underlying deformation ...
Although multiple methods have been developed to detect metal cations, only a few offer sensitivities below 1 pM, and many require complicated procedures and sophisticated equipment. Here, we describe a class of simple solid-state sensors for the ultrasens ...
A method for predicting selective performance of an adsorbent is disclosed. The adsorbent is selected from a list of metals and/or metal cations for use in removing contaminants as thiophene derivatives in hydrocarbon feed. The metals or metal cations are ...
Open-pore 99.99% pure Al and Al-5 wt.% Mg foam produced by replication, with pores either 400 or 75 gm in average diameter, are tested in compression with repeated relaxation cycles, at room temperature. Similar data are collected on pure aluminium. Estima ...
We address the lattice deformation of 1T-TiSe2 within the exciton condensate phase. We show that, at low temperature, condensed excitons influence the lattice through electron-phonon interaction. It is found that at zero temperature, in the exciton condens ...
A novel approach based on the Stober method allows breaking of the symmetry of core-shell systems based on metallic core and metal oxide shell. By adjusting the proportion of the TiO2 precursor with regard to the silica precursor, different morphologies of ...
Metal ions and compounds are essential to life and many people routinely take them as food supplements in the form of vitamin and mineral pills. Most non-essential metals are considered to be toxic, nevertheless, many are widely used in imaging, diagnostic ...
The linking of atomistic simulations of stress-driven processes to experimentally observed mechanical behavior via the computation of activation energy barriers is a topic of intense current research. Using dislocation nucleation from a crack tip as the re ...
Arsenic, chromium, cobalt and lead are among the most metalloid and metals present in the environment. When present in soil and water, they can be accumulated inside living organisms, enter several food chains and due to their toxicity affect human health. ...
Degradation of mechanical properties due to nanometric irradiation induced defects is one of the challenging issues in designing ferritic materials for future nuclear fusion reactors. Various types of defects, namely dislocation loops, voids, He bubbles an ...
