TL;DR: In this paper, a procedure for obtaining and characterization active silica with a high specific surface area from rice husk ash was developed, and the relative amount of silica was increased after burning out the carbonaceous material at different times and temperatures.

TL;DR: Amorphous nano-silica (nS) particles were incorporated in cement pastes and mortars, and their effect on the fresh state behavior was analysed as mentioned in this paper, where the influence of nS content was better observed on yield stress when compared with plastic viscosity values (the first increased about 66.5% while the latter just increased 3.6%).

TL;DR: In this article, the water-based tape casting of ceramic powders is reviewed and the formulation and processing parameters of aqueous tape casting are discussed. Statistical design of experiments was used for the improvement of the process.

TL;DR: In this article, the operation principles of SOEC and SOFC and the current state of the electrolyte, fuel and oxygen electrodes have been reviewed and discussed in detail, each major section is divided into materials families, including manufacturing issues.

TL;DR: In this article, the use of nano-SiO2 and nano-TiO2 (nT) in cement pastes and mortars was reported, and the results of kinetics of hydration followed the same tendency found by rheology.
