This collaborative research project is being undertaken by Dr. Yulin Deng, Georgia Tech Research Corporation at the Georgia Institute of Technology, and Dr. Said El-Sheikh, Central Metallurgical Research and Development Institute of Egypt, on the topic of preparing nano-fillers from waste materials for use in the paper industry. The research will determine whether inclusion of nano-filler particles in paper can improve the mechanical properties (e.g. smoothness, increased surface area) without compromising paper weight or processing characteristics. Further, tailoring the shape and structure of the nano-fillers to increase surface area should reduce the overall amount of filler needed without adversely impacting tensile strength. The prepared nano-fillers will be characterized in terms of size and phase structure, surface morphology and structural properties, bond types, and nanostructural surface charge. The prepared paper with incorporated nano-fillers will be characterized in terms of optical, physical, mechanical properties. Printability will be also investigated focusing on print density, print gloss and ink transfer.The scientific community and paper industry will benefit from the results of the proposed research to explore alternate materials for influencing key properties of paper processing. Nano-fillers may offer special properties of value in specific industry applications. The results may also offer insight into the dispersion behavior of fine calcium carbonate particles and how surface chemistry can be controlled to create nanoscale morphologies. There is a reasonable likelihood that useful, low-cost mineral products can be produced and that such use can help alleviate a waste disposal issue and displace more expensive mineral products. Further, the international exchange, involving green technology, may foster future progress in related fields in both countries. The collaboration is taking place between two highly skilled research institutes and involves US and Egyptian junior scientists.The project is funded under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to undertake cooperative research.

该合作研究项目由佐治亚理工学院佐治亚理工学院研究公司的尤林·邓博士（Yulin Deng）博士和埃及中央冶金研究与开发研究所的El-Sheikh博士在纸箱行业中供应供应供应材料的纳米填充者。 该研究将确定在纸张中包含纳米填充物颗粒是否可以改善机械性能（例如光滑度，表面积增加）而不会损害纸张重量或加工特征。此外，定制纳米填充剂的形状和结构以增加表面积，应减少所需的总体填充物，而不会产生不利影响的拉伸强度。准备好的纳米填充剂将以大小和相结构，表面形态和结构特性，键类型和纳米结构表面电荷来表征。与光学，物理，机械性能一起，准备好具有纳米填充剂的准备好的纸张。还将研究关注印刷密度，印刷光泽和墨水传输的可打印性。科学界和造纸行业将受益于拟议研究的结果，以探索替代材料，以影响纸张处理的关键特性。 纳米填充者可以在特定行业应用中提供价值的特殊属性。结果还可以洞悉碳酸钙颗粒的色散行为以及如何控制表面化学以产生纳米级形态。有可能生产有用的低成本矿物产品的可能性合理的可能性，并且这种用途可以帮助减轻废物处理问题并取代更昂贵的矿物产品。此外，涉及绿色技术的国际交流可能会促进两国相关领域的未来进步。 该合作是在两家高技能研究机构之间进行的，并涉及我们和埃及初级科学家。该项目是根据美国埃及联合基金计划资助的，该计划为两国的科学家和工程师提供了合作研究的赠款。
