  • Solid modeling (or modelling) is a consistent set of principles for mathematical and computer modeling of three dimensional solids. Solid modeling is distinguished from related areas of Geometric modeling and Computer graphics by its emphasis on physical fidelity [1]. Together, the principles of geometric and solid modeling form the foundation of Computer-aided design and in general support the creation, exchange, visualization, animation, interrogation, and annotation of digital models of physical objects....

  • Introduction: Mixed ionic–electronic conductors (MIECs) have been and continue to be of interest for strategic applications related to energy conversion and environmental monitoring including batteries, fuel cells, permeation membranes, and sensors. Within solid oxide fuel cells (SOFCs), for instance, nanostructured ionic and electronic conducting materials can increase the electrochemical performance of the cathode and thus could potentially facilitate lower-temperature operation and thereby provide faster start-up times, improved stability, and less complicated thermal management. ...

  • Introduction: The ceramic oxide known as ‘beta alumina’ exhibits remarkably high conductivity of sodium ions and, as a consequence, has been adopted as a key component in batteries that employ liquid sodium as the active material at the negative electrode. Most rechargeable (or ‘secondary’) batteries comprise solid electrodes and a liquid electrolyte. A separator is placed in the electrolyte between the plates to prevent a short circuit.

  • In recent years there has been a renewed interest in solid-state fermentation (SSF) processes for the production of bioactive compounds. While efforts continue largely to exploit filamentous fungi and yeasts for the production of various enzymes, attempts have also been made to explore possibilities of using bacterial strains in SSF systems (Pandey et al., 2000). Enzyme production by SSF using bacterial spp.

  • A new automated procedure for preconcentration and analysis of anionic surfactants in water using solid-phase extraction (SPE) in a flow injection (Fl) system together with an UV-vis detection is reported in this paper. The method involves extraction of blue coloured ion-pair complex of anionic surfactants and methylene blue into solid phase and their elution from the SPE column with organic solvent (chloroform stabilised with methanol) and subsequent measurement in an UV-vis flow cell at 650 nm. The system is well optimised before to apply for analysis of real samples.

  • First-principles calculations based on the density functional theory are used to study the electronic structure of LaNiO3 perovskite for application of cathode material in solid oxide fuel cell. Our results show that bulk LaNiO3 exhibits metallic behavior. For 1x1x1 LaNiO3 unit cell, increasing in-plane strain leads to the increase in the density of states (DOS) at the Fermi level.
