TL;DR: In this article, the electrochemical properties of the interfaces between porous composites of La 06 Sr 04 Co 02 Fe 08 O 3−δ /Ce 09 Gd 01 O 2− δ cathodes have been investigated at intermediate temperatures (500-700°C) using AC impedance spectroscopy.

TL;DR: In this article, the average temperature difference between the bulk and the cylinders which are heated uniformly under conditions of small Reynolds and Peclet numbers is calculated for the slow flow past a square and a hexagonal array of cylinders using a somewhat nonconventional numerical method.

TL;DR: In this paper, three types of materials were investigated: silica for investment casting, alumina and silicon nitride for structural parts, and three-dimensional objects were fabricated from a 0.50 volume fraction silica suspension.
Abstract: Ceramic green bodies can be created using stereolithography methods where a ceramic suspension consisting of 0.40–0.55 volume fraction ceramic powder is dispersed within an ultraviolet-curable solution. Three ceramic materials were investigated: silica for investment casting purposes, and alumina and silicon nitride for structural parts. After mixing the powders in the curable solution, the ceramic suspension is photocured, layer by layer, fabricating a three-dimensional ceramic green body. Subsequent binder removal results in a sintered ceramic part. Three-dimensional objects have been fabricated from a 0.50 volume fraction silica suspension.

TL;DR: In this article, the morphology, crystallinity and mechanical properties of electrospun poly(e-caprolactone) nonwoven mats were characterized by scanning electron microscopy (SEM), wide angle X-ray diffraction (WAXD) and universal testing method (UTM), respectively.

TL;DR: In this article, a new model is presented to describe the hardening behavior of cell-forming crystalline ma- terials at large strains, based on a cellular dislocation structure consisting of two phases: the cell walls and the cell interior.
