polyimide aerogel fibers with superior flame resistance strength hydrophobicity and flexibility made via a universal sol gel confined Transition Strategy
ACS Nano, 2021Co-Authors: Guoqing Dong, Zengwei Liu, Xuetong ZhangAbstract:Aerogel fibers with ultrahigh porosity, large specific surface area, and ultralow density have shown increasing interest due to being considered as the next generation thermal insulation fibers. However, it is still a great challenge to fabricate arbitrary aerogel fibers via the traditional wet-spinning approach due to the obvious conflict between the static sol-gel Transition of the aerogel bulks and the dynamic wet-spinning process of aerogel fibers. Herein, a sol-gel confined Transition (SGCT) Strategy was developed for fabricating various mesoporous aerogel fibers, in which the aerogel precursor solution was first driven by the surface tension into the capillary tubes, then the gel fibers were easily formed in the confined space after static sol-gel process, and finally the mesoporous aerogel fibers were obtained via the supercritical CO2 drying process. As a typical case, the polyimide (PI) aerogel fiber prepared via the SGCT approach has exhibited a large specific surface area (up to 364 m2/g), outstanding mechanical property (with elastic modulus of 123 MPa), superior hydrophobicity (with contact angle of 153°), and excellent flexibility (with curvature radius of 200 μm). Therefore, the aerogel woven fabric made from PI aerogel fibers has possessed an excellent thermal insulation performance in a wide temperature window, even under the harsh environment. Besides, arbitrary kinds of aerogel fibers, including organic aerogel fibers, inorganic aerogel fibers, and organic-inorganic hybrid aerogel fibers, have been fabricated successfully, suggesting the universality of the SGCT Strategy, which not only provides a way for developing aerogel fibers with different components but also plays an irreplaceable role in promoting the upgrading of the fiber fields.

towards the digital government of the 21 st century
International Conference on Digital Government Research, 2002Co-Authors: Herbert Schorr, Salvatore J StolfoAbstract:A partnership between Government agencies and the information technologies research community has succeeded in the past for the benefit of the Nation. The most notable example is the emergence of the Internet as the basis for broad scientific, cultural, civic, and commercial discourse, evolving from what was originally a Government-supported networking research project. The collaborative development of a new applied research domain is critical to help meet the Nation's growing information service demands. Applied research that considers real world operating constraints can provide valuable new problems and insights for the academic research domain, leading to new demonstrable and deployable systems. This applied research domain is a National Challenge to provide a Transition Strategy for migrating Federal Information Services from legacy systems, through the interoperable systems of the Internet, and toward more advanced integrated global systems. A unique opportunity exists for a new paradigm for interaction between Government and citizen; an opportunity to invent the
