The influence of silica-coated nanoscale titanium dioxide on the microstructure, mechanical properties, and carbonation resistance of cementitious materials

Nanomaterials possess great application prospects in improving the performance of cementitious materials.However, their high agglomeration hinders their efficient utilization in cementitious matrices.Consequently, surface modification has recently attracted attention as a method to enhance dispersibility.In this study, silica was employed to modify

Applying genomics to metapopulation management in North American insurance populations of southern sable antelope (Hippotragus niger niger) and addra gazelle (Nanger dama ruficollis)

Insurance populations can provide a short-term safeguard for at-risk species.The goal for all insurance populations should be to maintain a high welfare, genetically diverse, self-sustaining population that is available for eventual reintroduction of animals back into the wild when it is safe to do so.However, many insurance populations in zoos are
