INTRODUCTION The importance of perfect apical seal in endodontics, more specifically in periradicular surgery, is the motivation/reason for development of root-end filling materials with favorable physical, chemical and biological characteristics. The aim of this in vitro study was to evaluate the marginal adaptation of root-end filling materials using scanning electron microscopy. MATERIALS ...
Combining atomically-thin van der Waals materials into heterostructures provides a powerful path towards the creation of designer electronic devices. The interaction strength between neighbouring layers, most easily controlled through their interlayer separation, can have significant influence on the electronic properties of these composite materials. Here, we demonstrate unprecedented control ...
The preparation of cementitious materials by replacing part the cement with activated coal gangue is great significance to industry in terms carbon reduction and coal-based solid waste utilization. For this paper, material was prepared firing under suspension conditions batching it limestone powder using Inner Mongolia as raw material. optimal ratio determined testing strength changes at 3, 7, ...
