The synthesis and characterization of a platinum (II) terpyridine system tethered with a latent organic dye of rhodamine derivative as colorimetric and fluorescent sensory moiety has been reported to show selective Hg2+ion sensing behavior. The interplay of aggregation/de-aggregation behavior of the alkynylplatinum (II) terpyridine complex and the ring-opening process of rhodamine derivative has been investigated. The spectral change of aggregation NIR emission at 800 nm and rhodamine fluorescence at 585 nm provides a possible ratiometric luminescence measurement. Morphological studies from TEM and SEM images showing nanospherical structures confirmed the aggregation in the absence of Hg 2+ ion.

Abstract

A method for peeling laminated nano-particle, comprising the following steps: (1) intercalating laminated nano-particles with an intercalating agent to obtain intercalated nano-particles; (2) peeling the intercalated nanoparticles prepared in step (1) with a maleic anhydride graft to obtain peeled nano-particles. The present peeling method employs an intercalating agent to intercalate laminated nano-particles, so as to obtain intercalated nano-particles; and then a maleic anhydride graft is used to peel the intercalated nano-particles. Since the maleic anhydride graft contains both a polar aldehyde group and a non-polar olefin segment provided by the maleic anhydride, under high temperature and screw shearing, the anhydride and the polar group (e.g., an amine group) undergo a general dehydration reaction to form a chemical bond, thereby chemically coupling the incompatible polar and non-polar substances, achieving peeling and dispersing of the laminated nano-particles, as well as functions for coupling to improve compatibility.

The optimization method comprises the step P1 used for determining a system pre-allocated parameter set and provides an automatic solving method of the step P1. The present invention provides a feasible multicarrier broadband information and energy simultaneous transfer optimization method that gives consideration to wireless energy supply and an information transmission rate and that implements automatic configuration. An information signal is sent to a reception end and an independent energy signal is sent at the same time, and energy required by a working mode of the reception end can be provided. In addition, information signals and energy signals are optimized by means of an optimization algorithm, so that the energy transmission efficiency can be improved and the information rate can be increased. The present invention can be widely used in a variety of information and energy simultaneous transfer systems.

Abstract

The present invention relates to a reception method and system in simultaneous transfer of digital information and energy. The reception method comprises: receiving information and energy serial simultaneous transfer analog signals, and converting the information and energy serial simultaneous transfer analog signals into information and energy parallel simultaneous transfer analog signals; separating information analog signals from energy analog signals among the information and energy parallel simultaneous transfer analog signals; carrying out analog-to-digital conversion on the information analog signals to obtain information digital signals, and performing information demodulation, parallel-serial conversion and decoding processing on the information digital signals in a digital domain; and preprocessing the energy analog signals in an analog domain and then storing the energy analog signals into an energy storage unit. In the present invention, information signals among digital information and energy simultaneous transfer signals are separated from energy signals among the digital information and energy simultaneous transfer signals; the information signals are demodulated and decoded in a digital domain while the energy signals are processed in an analog domain, so that a reception end can fully collect the energy signals among the simultaneous transfer signals.
