Abstract: A temperature sensor includes a NAND gate and a plurality of delay units. The NAND gate includes a first and a second input terminals, and an output terminal. The first input terminal is configured to receive an external starting control signal. The plurality of delay units are connected in series. An input end of the first delay unit is connected to the output terminal of the NAND gate. An output end of the last delay unit is connected to the second input terminal of the NAND gate, thereby forming a ring oscillator structure. The temperature sensor can realize conversion of temperature-leakage-frequency based on the ring oscillator structure in a temperature range of ?40˜125° C., thereby simplifying design complexity and achieves high accuracy.

Abstract: An analog-to-digital conversion method and an A/D conversion device for a temperature sensor are provided. An analog front-end circuit generates an A/D converter input signal positively correlated to a temperature and an A/D converter reference voltage signal negatively correlated to the temperature, and an operation is performed on a ratio of amplitudes of the generated signals to obtain a quantized output value. Since the amplitude of the A/D converter input signal is less than that of the A/D converter reference voltage signal, measurements on other signals is compatible with the measurement on the temperature in a multi-sensor system. A digitized output value is calculated by a digital-assisted readout method to generate a linear output relating to a temperature, thereby improving the accuracy of temperature measurement and reducing complexity of analog circuit design.

Abstract: Described are compositions comprising amphiphilic polymer nanoparticles, such as DSPE-PEG, encapsulating a photostable agent with aggregation-induced emission (AIE) characteristic. The photostable AIE agents are preferably small organic molecules with tetraphenylethylene moieties. The nanoparticles are synthesized by a modified nanoprecipitation method and the size of the nanoparticles is controlled by varying the loading ratio, the solvent ratio and the tatio of hydrophilic to hydrophobic length of the polymer. The nanoparticles are surface modified with a conjugatable group for covalently linking to at least one targeting moiety, such as antibodies or affibodies to IgG, EGFR and Her2. Methods for immunostaining or imaging or detecting or tracking a live cell, such as cancer cells, using the nanoparticle compositions are described.

Abstract: Provided herein is a narrow-range polyacetylene ester compound and a preparation method. The narrow-range polyacetylene ester compound has a structural formula as represented by formula (I). The method includes: in atmospheric carbon dioxide environment, a bifunctional alkyne monomer, carbon dioxide, and a dihalide monomer perform polymerization reaction by means of a combined action of a catalyzer and alkali, dissolve the product into an organic solvent, then add same to a precipitant for precipitation, collect precipitates, and dry same to the constant weight to obtain the narrow-range polyacetylene ester compound. The reaction is carried out in atmospheric carbon dioxide atmosphere, and carbon dioxide is involved as a monomer in the formation of a polymer. The obtained narrow-range polyacetylene ester compound has good thermal stability and excellent processability. Due to introduction of an aggregation-induced emission group, some polymers show a typical aggregation-induced emission performance.
