A new procedure is reported to synthesis mesoporous silica micro sphere for the first time. In these method two surfactants namely Span 80 and Tween 80 were used. Small angle X ray diffraction and N2 adsorption analysis shows the synthesized material has mesoporous property. The material has spherical morphology with 1-10 μm particle size. Beside the material found to have microcapsule property...
Action on climate, the environment, and the efficient use of raw materials and resources are important challenges facing our society. Against this backdrop, the construction industry must adapt to new trends and environmentally sustainable construction systems, thus requiring lines of research aimed at keeping energy consumption in new buildings as low as possible. One of the main goals of this...
Acylation of bis[2-(diphenylphosphino)ethyl]amine provides a flexible synthesis of functionalized chelating diphosphines. This t.uitiott off"rs a route to diphosphine complexes of transition metals having a wide r?n-ge of structures and physical properties and especially to water-soluble complexes. The aqueous solubility of the free ligands and of ttre compleres prepared from them depend on the...
This chapter reviews selected physical properties of food and biological materials. The primary emphasis is upon mechanical and thermal properties, although electromagnetic properties are briefly reviewed.
Spatio-temporal patterns are ubiquitous in different areas of materials science and biological systems. However, typically the motifs in these types of systems present a random distribution with many possible different structures. Herein, we demonstrate that controlled spatio-temporal patterns, with reproducible spiral-like shapes, can be obtained by electrodeposition of Co-In alloys inside a c...
