    • An aqueous dispersion of silica particles is mixed with a dialkyldialkoxysilane monomer, e.g., dimethyldiethoxysilane (DMDES), typically under basic conditions. Optionally, the monomer, or a portion thereof, is partially reacted prior to mixing, such that it is possible for a polydialkylsiloxane oligomer, e.g., polydimethylsiloxane (PDMS), to be added either with or instead of the monomer. The addition of the monomer (or oligomer) induces gelation of the silica. The contemplated mechanism is that the silanol groups on the growing polydialkylsiloxane chains are able to condense with silanol groups found on the silica particle surfaces, thereby anchoring the chains to the particles. These chains appear to have the ability to form bridges between particles and/or loops on individual particles. Such bridges appear to initiate formation of a silica particle network, and both the bridges and loops increase the silica particles' hydrophobicity. Both of these features contribute to gelation of the silica particles, substantially independent of the particles' surface charge.
    • 二氧化硅颗粒的水分散体通常在碱性条件下与二烷基二烷氧基硅烷单体例如二甲基二乙氧基硅烷(DMDES)混合。 任选地,单体或其一部分在混合之前部分反应,使得聚二烷基硅氧烷低聚物例如聚二甲基硅氧烷(PDMS)可以用或代替单体加入。 单体(或低聚物)的添加诱导二氧化硅的凝胶化。 预期的机理是生长的聚二烷基硅氧烷链上的硅烷醇基能够与在二氧化硅颗粒表面上发现的硅烷醇基团缩合,从而将链锚定到颗粒上。 这些链似乎具有在单个颗粒上的颗粒和/或环之间形成桥的能力。 这样的桥似乎引起二氧化硅颗粒网络的形成,并且桥和环都增加二氧化硅颗粒的疏水性。 这两个特征有助于二氧化硅颗粒的凝胶化,基本上与颗粒的表面电荷无关。

    • A method includes conforming an arrangement of an optical fiber to an object to detect tampering with the object when the optical fiber arrangement is changed, measuring an optical signature of the optical fiber arrangement in a first measurement, measuring the optical signature of the optical fiber arrangement at a time after the first measurement in a second measurement, and comparing the first and second measurements to detect tampering with the object from a change in the optical fiber arrangement. In another embodiment, an optical shield includes an optical fiber arranged to detect tampering with an object resulting from a change in the optical fiber arrangement and an optical fiber carrier coupled to the optical fiber for conforming the optical fiber arrangement to the object.
    • 一种方法包括:当光纤布置改变时,使光纤的布置符合物体以检测对物体的篡改,在第一测量中测量光纤布置的光学特征,测量光纤布置的光学特征 在第二测量中的第一次测量之后的时间,并且比较第一和第二测量值以从光纤配置的变化中检测对物体的篡改。 在另一个实施例中,光学屏蔽包括光纤,其布置成检测由于光纤布置的变化而导致的物体的篡改,以及耦合到光纤的光纤载体,用于使光纤布置与物体一致。
