TL;DR: In this paper, a review of the recent advances in sol-gel processed porous bioactive glasses in biomedical fields, especially for bone tissue regeneration applications have been comprehensively reviewed, where different approaches frequently used for the solgel synthesis of porous glasses such as microemulsion and acid-catalyzed based synthesis have been reviewed.

TL;DR: In this paper, the effect of aggregate gradation according to Fuller's model on mechanical strength and thermomechanical behavior during and after thermal exposure at 1000°C was investigated, and the results have shown that a higher content of fine ceramic particles under 90 µm and gradual distribution of other fractions from 150 to 710 ´m leads to an improved dimensional stability after thermal stress.

TL;DR: In this article, a review of surface modifications for osteointegration in dental and orthopedic implant materials is presented, with an introduction to the basics of cell-material interactions as well as common surface modification techniques.

TL;DR: In this article, a facile and effective method for fabrication of open-cell ceramic foam derived from geopolymer precursor through replica technique was described, and the polyurethane sponge method was applied using a powder mixture of metakaolin/precipitated silica, potassium silica solution and fine chamotte filler.

TL;DR: The pH-responsive polymer shows transitions above or below a critical pH value of globule-to-coil nature, while functional materials display specific morphologies and characteristics revealing their ability to perform some crucial chemical, physical, and biological functions as mentioned in this paper.
