Preparation of TiO Nanotubes Loaded on Polyurethane Membrane and Research on Their Photocatalytic Properties.

To solve the problem of separation and recovery of photocatalyst in water, the modification of TiO was studied as well as its immobilization and photocatalytic properties. To improve surface properties, TiO nanotubes were synthesized by a hydrothermal method and silylated by silane coupling agents to introduce a certain functional group. Supported on polyurethane (PU) membrane, TiO nanotubes were prepared to produce immobilized PU/TiO.

One-Pot Hydrothermal Synthesis of Carbon Dots with Efficient Up- and Down-Converted Photoluminescence for the Sensitive Detection of Morin in a Dual-Readout Assay.

Blue luminescent carbon dots (CDs) with a high photoluminescence (PL) quantum yield (48.3 ± 5.3%) were prepared by the one-pot hydrothermal reaction of citric acid with poly(ethylenimine) (PEI).

Coligand modifications fine-tuned the structure and magnetic properties of two triple-bridged azido-Cu(ii) chain compounds exhibiting ferromagnetic ordering and slow relaxation.

Employing two benzoate derivatives with different numbers of non-coordinated fluoro-substituents, 2-fluorobenzoic acid (2-Hfba) and 2,6-difluorobenzoic acid (2,6-Hdfba), two new azido-copper coordination polymers, [Cu(2-fba)(N)(CHOH)] (1) and [Cu(2,6-dfba)(N)(CHOH)] (2), have been successfully isolated, and then structurally and magnetically investigated. Single crystal structure analysis demonstrates that the metal cations in the two resulting compounds are connected by the alternating triple-bridge of μ-1,1-azido, syn,syn-carboxylate and μ2-methanol, contributing to analogously linear 1D Cu(ii) chain-like motifs with slightly different intrachain and interchain geometric parameters. The fine-tuned structures lead to variant magnetic properties in the two title compounds.

Controlled synthesis of BiVO/SrTiO composite with enhanced sunlight-driven photofunctions for sulfamethoxazole removal.

The presence of antibiotics in surface waters is paid more and more attention, which is difficult to be removed by conventional treatment technology, and photocatalytic technology is considered to be a promising method for antibiotics pollutant removal. In the present work, a novel heterojunction photocatalyst was successfully synthesized by self-template method under hydrothermal condition. The photocatalytic activity of as-prepared samples was investigated by degradation of sulfamethoxazole in aqueous solution.

Comparative genomic and transcriptomic analyses of the Fuzhuan brick tea-fermentation fungus Aspergillus cristatus.

Background: Aspergillus cristatus is the dominant fungus involved in the fermentation of Chinese Fuzhuan brick tea. Aspergillus cristatus is a homothallic fungus that undergoes a sexual stage without asexual conidiation when cultured in hypotonic medium. The asexual stage is induced by a high salt concentration, which completely inhibits sexual development.

Effects of spatiotemporal variation of soil salinity on fine root distribution in different plant configuration modes in new reclamation coastal saline field.

In order to study the effects of salinity on plant fine roots, we considered three different plant configuration modes (tree stand model (TSM), shrub stand model (SSM), and tree-shrub stand model (TSSM)). Soil samples were collected with the method of soil drilling. Significant differences of electrical conductivity (EC) in the soil depth of 0-60 cm were observed among the three modes (p < 0.

A Virtual Instrument System for Determining Sugar Degree of Honey.

This study established a LabVIEW-based virtual instrument system to measure optical activity through the communication of conventional optical instrument with computer via RS232 port. This system realized the functions for automatic acquisition, real-time display, data processing, results playback, and so forth. Therefore, it improved accuracy of the measurement results by avoiding the artificial operation, cumbersome data processing, and the artificial error in optical activity measurement.

The Ru complex and hollow gold nanoparticles branched-hydrogel as signal probe for construction of electrochemiluminescent aptasensor.

In this work, a novel Ru complex and hollow gold nanoparticles branched-poly(N-(3-aminopropyl)methacrylamide) hydrogel composites (pNAMA-Ru-HGNPs) were prepared and used as electrogenerated chemiluminescence (ECL) signal probe to construct aptasensor for ultrasensitive detection of thrombin (TB). Herein, [Ru(phen)2(cpaphen)](2+) linked N-(3-aminopropyl)methacrylamide and hollow gold nanoparticles functionalized N-(3-aminopropyl)methacrylamide were used as two polymer monomers to prepare pNAMA-Ru-HGNPs composites via free-radical polymerization. The obtained hydrogel composite, containing amount of Ru complex and HGNPs, were used as effective tag-carriers for the immobilization of thrombin binding aptamer II (TBA II) to form the pNAMA-Ru-HGNPs labeled TBA II (pNAMA-Ru-HGNPs-TBA II).

Metzia parva, a new cyprinid species (Teleostei: Cypriniformes) from south China.

A new species of a small cyprinid fish, Metzia parva sp. nov., is described here based on specimens collected from a tributary of Hongshui-He River in the Pearl River basin at Anyang Town, Du'an County, Guangxi Province, south China.

A novel ECL biosensor for β-lactamase detection: Using RU(II) linked-ampicillin complex as the recognition element.

In this work, Ru(phen)2(cpaphen)(2+) linked-ampicillin (Ru-Amp), as the novel specific recognition element, was proposed to construct a simple and sensitive electrogenerated chemiluminescence (ECL) biosensor for the determination of β-lactamase. Here, Ru-Amp complex acted not only as a novel specific recognition element for β-lactamase but also as the ECL Luminescent reagent. Through electrostatic adsorption and the intermolecular π-π interactions, a large amount of Ru-Amp was immobilized to gold nanoparticles (TA@AuNPs) prepared by thiophenemalonic acid (TA) to obtain Ru-Amp/TA@AuNPs nanocomposites.

Granular computing with multiple granular layers for brain big data processing.

Big data is the term for a collection of datasets so huge and complex that it becomes difficult to be processed using on-hand theoretical models and technique tools. Brain big data is one of the most typical, important big data collected using powerful equipments of functional magnetic resonance imaging, multichannel electroencephalography, magnetoencephalography, Positron emission tomography, near infrared spectroscopic imaging, as well as other various devices. Granular computing with multiple granular layers, referred to as multi-granular computing (MGrC) for short hereafter, is an emerging computing paradigm of information processing, which simulates the multi-granular intelligent thinking model of human brain.
