The advantages of plotting ac data in terms of impedance, electric modulus and dissipation
factor simultaneously are illustrated. Complex impedance is generally employed for ionic …

The 25-year history and development of an ultra-small-angle X-ray scattering (USAXS)
instrument dedicated to serving materials research is presented and discussed. The …

Experimental method of determination of the fractal dimensions of fractal aggregates are
described. The results of studies on aggregation of colloidal particles in different regimes are …

Дисперсные системы достаточно широко распространены в природе. Составная часть
этих систем ì агрегаты коллоидных частиц ì одни из первых физико-химических …

During tensile creep of a hot isostatically pressed (HIPed) silicon nitride, the volume fraction
of cavities increases linearly with strain; these cavities produce nearly all of the measured …

The ongoing quest to increase gas turbine efficiency and performance (increased thrust)
provides a driving force for materials development. While improved engine design and …

This paper describes the results from multidisciplinary characterization/scattering techniques
used for the quantitative characterization of industrial thermal barrier coating (TBC) systems …

Arylene-bridged polysilsesquioxanes are an interesting class of porous materials prepared
by sol− gel processing of ethoxysilane monomers in which there are two or more …

Nanoparticles of certain materials can respond structurally to changes in their surface
environments. We have previously shown that methanol, water adsorption, and …

A model capable of predicting pore characteristics and rendering representative images of
porous materials is described. A long-term goal is to discriminate between open and closed …
