Abstract: A method of synthesizing core-shell nanohybrids is described herein. The method includes providing first nanoparticles and second nanoparticles in a liquid medium at a pH at which the first nanoparticles are neutral and the second nanoparticles are negatively charged, allowing the first nanoparticles to homoaggregate and form a core of at least one of the first nanoparticles, and allowing the second nanoparticles to heteroaggregate with the homoaggregated first nanoparticles to form a shell on the core so as to provide the core-shell nanohybrids. A nanohybrid is additionally described herein, which includes a core including at least one neutral nanoparticle within a shell containing charged nanoparticles, wherein the shell further includes nanogaps configured to allow access of substrates to the core.

Abstract: An output-decision-based negative feedback control method and system. The method includes: receiving, by an output decider, output responses of at least two heterogeneous functional equivalents, and dividing numbers corresponding to the at least two heterogeneous functional equivalents into at least one set according to the output responses; determining, by the output decider, credibility of each set according to the output responses, and sending the at least one set and the credibility corresponding to each set to a feedback controller via decision information; generating, by the feedback controller, a first scheduling policy and/or a second scheduling policy according to the decision information; and sending, by the feedback controller, the first scheduling policy to an input proxy, and/or sending a change instruction to the heterogeneous functional equivalent indicated by the second scheduling policy. The method can prevent in advance and process a heterogeneous functional equivalent that may be faulty.
