摘要:
A method for synthesizing ultrabright fluorescent silica particles with hydrophilic functional groups, comprising the steps of: (i) forming a first mixture comprising a plurality of nano-sized silica particles and a gelation agent; (ii) forming a second mixture by combining the first mixture with a surfactant, a plurality of fluorescent dye molecules, and water, wherein fluorescent dye molecules are encapsulated within a plurality of pores of the nano-sized silica particles; (iii) forming a third mixture by adding a co-source of silica to the second mixture, wherein the co-source of silica prevents leakage of the encapsulated fluorescent dye molecules from the pores of the nano-sized silica particles and provides hydrophilic functional groups to the silica particles while preserving the fluorescence of the silica particles; (iv) optional further functionalization of the obtained nanoparticles with functional molecules, exemplified by carboxylic groups and folic acid, and (v) removing excess fluorescent dye from the third mixture.

Disclosed are electronic systems and techniques for implementing lists that include source of origin information for items added to the lists. A portal can include a component that enables items to be added to lists associated with the portal from a variety of sources, such as social networks, other portals, advertisements, search engines, other users, etc. In this regard, the items can be added to a list with references to the portal, instead of the source of origin, and information relating to the source of origin can be maintained to assist users in future prioritizations of items included in the list.
摘要:
The invention is an apparatus and method including hardware and software, which allows collecting and analyzing data to obtain information about mechanical properties of soft materials in a much faster way. The apparatus can be used as a stand-alone device or an add-on to the existing AFM device. The apparatus allows collecting dynamical measurements using a set of multiple frequencies of interest at once, in one measurement instead of sequential, one frequency in a time, measurements.
摘要:
This disclosure describes a self-assembly templating of a cationic surfactant in the presence of a silica precursor that is free of an excessive variability of the assembled shapes and has a yield approaching one hundred percent. This disclosure describes a self-assembly process that includes cooling and keeping a resultant solution at cold temperatures during the synthesis.

摘要:
Video content is identified by a source component via a processor from a plurality of media sources comprising at least two of a wireless broadcast media channel, a web site, a web data feed, and/or a wired broadcast channel for communication via a personalized video channel. A demographic component is configured to classify a user device in a demographic class based on demographic data. A set of predicted video content is generated from the video content of the plurality of media sources based on the demographic data with a prediction component. A streaming component is configured to communicate the set of predicted video content from the plurality of media sources to a mobile component via the personalized video channel and re-configure the personalized video channel to communicate, at different times, the video content identified from different media sources of the plurality of media sources.
摘要:
The object of the invention is to producing ultras bright fluorescent silica particles by synthesizing large nanopore silica particles with self sealed channels/pores and then stopping the synthesizing before large nanopore silica particles have been formed, wherein said sintering solution has produced nanoparticles. The large nanopore silica particles are micron size. The synthesizing is stopped by diluting said synthesizing solution with a neutralizing medium such as an aqueous solution of definite acidity of pH7 and higher an exemplary value of pH11 (sodium hydroxide). The time range for stopping the synthesizing ranges from tens of seconds to ten of minutes.
