U.S.-Mexico Collaborative Research: Formation and Characterization of Calcium Hydroxyapatite Deposited on Silica Aerogels and Xerogels

这项美国-墨西哥奖将支持北德克萨斯大学的Richard Reidy教授和Saltillo理工学院的Oscar Mendoza Gonzalez教授以及cinvest - queretaro的同事在生物材料领域的联合合作。更具体地说，研究人员将重点关注二氧化硅干凝胶和气凝胶的结构和表面功能之间的关系，以及由此产生的生长机制、组成和羟基磷灰石的形态，这些生长在模拟体液的基质上。利用小角度中子散射、气体吸附、电子显微镜以及合作机构提供的一系列仪器和专业知识，这项研究合作的结果将在开发具有许多潜在生物工程应用的廉价生物活性或可吸收生物陶瓷材料方面证明是有用的。

0102797ReidyThis U.S.-Mexico award will support joint collaborative work between Prof. Richard Reidy of the University of North Texas and Prof. Oscar Mendoza Gonzalez of the Instituto Tecnologico de Saltillo together with colleagues at CINVESTAV-Queretaro, in the field of biomaterials. More specifically, the researchers will focus on the relationship between the structure and surface functionalities of silica xerogels and aerogels and the consequent growth mechanisms, compositions, and morphologies of hydroxyapatites grown on these substrates from simulated body fluids. Using small-angle neutron scattering, gas adsorption, electron microscopy, and a range of instrumentation and expertise available at the collaborating institutions, the results of this research collaboration should prove useful in the development of inexpensive bioactive or resorbable bioceramic materials with many potential bioengineering applications.
