Hydrothermal carbonization of herbal medicine waste: Process parameters optimization, secondary char formation and its effect on hydrochar properties.

As a kind of high moisture organic solid waste, herbal medicine waste (HMW) is a carbon-neutral resource. This work used the response surface method, the central composite design (CCD), to explore the optimal conditions of the HMW HTC process. Based on the influence of secondary char (SC) on the properties of hydrochar (HC), the formation mechanism of SC was explored by analyzing the physical and chemical properties of HC, primary char (PC) and SC.

Investigation on the transformation behaviours of Fe-bearing minerals of coal in O/CO combustion atmosphere containing HO.

The transformation behaviors of Fe-bearing minerals in coals of Xinjiang (XJC) and Shenhua (SHC) were investigated in an O/CO atmosphere containing HO in a drop-tube-furnace (DTF). The solid products were characterized using XRD, Mössbauer spectroscopy, particle size analyzer and SEM-EDX techniques. The results show that the change in the combustion atmosphere does not significantly alter the main phases of Fe-bearing minerals in the coal ashes, but does affect their relative contents.

[Effects of salinity on the survival and asexual reproduction of Aurelia coerulea polyps at different temperatures].

The scyphozoan genus Aurelia is one of the main contributors causing jellyfish blooms in global coastal waters. The population and reproduction of polyps are important factors to the outbreak of jellyfish. In this study, the effects of different salinity on the survival and asexual reproduction of Aurelia coerulea polyps were explored, which were cultured at the high (21 ℃) and low temperature (12 ℃), respectively.

Torrefaction of herbal medicine wastes: Characterization of the physicochemical properties and combustion behaviors.

To explore the feasibility of using herbal medicine waste (HMW) as solid fuel, HMW was torrefied under different temperatures and atmospheres. The physicochemical properties and combustion behaviors of the torrefied HMW were investigated. Temperature was found to be the most influential factor affecting the torrefaction.

Quantum dots encoded Au coated polystyrene bead arranged micro-channel for multiplex arrays.

This paper describes a promising micro-channel multiplex immunoassay method based on the quantum dots encoded beads which requires micro-volume sample. Briefly, Au nanoparticles coated polystyrene (PS) beads were prepared and Quantum dots (QDs) were employed to encode 4 types of the PS beads by different emission wavelength QDs and various intensities. Different coding types of the beads were immobilized with different antibodies on the surface and BSA was used to block the unsatisfied sites.

The development of a fluorescence polarization immunoassay for aflatoxin detection.

A fluorescence polarization immunoassay (FPIA) was developed for the analysis ofaflatoxins (AFs) using an anti-aflatoxin B1 (AFB1) monoclonal antibody and a novel fluorescein-labeled AFB1 tracer. The FPIA showed an IC50 value of 23.33 ng/mL with a limit of detection of 13.
