The purpose of this study was to analyze in vitro the biological effects on human dental pulp stem cells triggered in response to substances leached or dissolved from two experimental cements for dental pulp capping.The experimental materials, based on extracts from Copaifera reticulata Ducke (COP), were compared to calcium hydroxide [Ca(OH)2] and
Titanium silicalite-1 (TS-1) is a milestone heterogeneous catalyst with single-atom tetrahedral titanium incorporated into silica framework for green oxidation reactions.Although TS-1 catalysts have been industrialized, the strategy of direct hydrothermal synthesis usually produces catalysts with low catalytic activities, which has still puzzled ac
In recent years, deep learning models have been widely used in 3D reconstruction fields and have made remarkable progress.How to stimulate deep academic interest to effectively manage the explosive augmentation of 3D models has been a research hotspot.This work shows mainstream 3D model retrieval algorithm programs based on deep learning currently
