    • A system is disclosed that facilitates construction project bidding, document distribution, and project management over a computer network. The system enables a project supervisor to efficiently transmit new project information and associated construction project files to one or more planroom provider systems. Each planroom provider system may make project information and associated construction project files available for transfer and viewing by one or more potential bidders connected to the planroom provider system over a public or private network. The planroom provider system(s) may provide a reference or link back to the project supervisor system to enable the potential bidder to bid on the construction project once the project information and project files have been reviewed.
    • 公开了一种通过计算机网络进行项目投标,文件分发和项目管理的系统。 该系统使项目主管有效地将新的项目信息和相关的建设项目文件传送到一个或多个计划供应商系统。 每个计划供应商系统可以使项目信息和相关的建设项目文件可供一个或多个通过公共或私人网络连接到计划室提供者系统的潜在投标人进行转移和查看。 一旦项目信息和项目文件被审查,计划供应商系统可以提供参考或链接回项目主管系统,以使潜在投标人能够对施工项目进行投标。

    • This invention relates to the development of a new Raman enhancing reagent and a surface-enhanced Raman scattering (SERS) method for rapid and ultra-sensitive detection and identification of perchlorate (ClO4−) and other anions such as technetium (TcO4−), uranium and nitrate in environmental samples. The method involves the synthesis of controlled gold nanoparticles which are modified with amine functional groups such as 2-(dimethylamino)ethanethiol and N,N,N-trimethylaminethiol. These functionalized Au nanoparticles were found to be reactive with perchlorate and other anions and can be used to detect these anions by Raman spectroscopy at ultra low concentrations in complex environmental matrices. This invention overcomes the limitations of currently-available analytical techniques by offering an inexpensive, rapid, ultra-sensitive, and real-time identification and detection of perchlorate and other anions. The technique is not only sensitive but also highly specific because of the unique Raman vibrational bands of perchlorate and other anions.
    • 本发明涉及新型拉曼增强试剂和表面增强拉曼散射(SERS)方法的开发,用于快速和超灵敏检测和鉴定高氯酸盐(ClO4-)和其他阴离子如锝(TcO4-),铀 和硝酸盐在环境样品中。 该方法涉及用胺官能团如2-(二甲基氨基)乙硫醇和N,N,N-三甲基氨基硫醇修饰的受控金纳米颗粒的合成。 发现这些官能化的Au纳米颗粒与高氯酸盐和其它阴离子反应,可用于通过拉曼光谱法在复杂环境基质中以超低浓度检测这些阴离子。 本发明通过提供廉价,快速,超灵敏和实时鉴定和检测高氯酸盐和其他阴离子来克服当前可用的分析技术的局限性。 由于高氯酸盐和其他阴离子的独特的拉曼振动带,该技术不仅敏感,而且具有高度的特异性。
