Synthesis of quadruply boron-doped acenes with stimuli-responsive multicolor emission.

Boron-doped acenes have attracted attention due to their unique structures and intriguing luminescent properties. However, the hitherto known boron-doped acenes have only one or two boron atoms, limiting the chemical space of this unique family of compounds and the capability to tune their optical properties. Herein, we report the synthesis of quadruply boron-doped acenes, including pentacene, heptacene, and nonacene.

Highly selective and visual detection of vanillin based on fluorescence Cd-MOF sensor in milk powders.

Vanillin is a commonly used synthetic flavoring agent in daily life. However, excessive intake of vanillin may pose risks to human health. Therefore, there is an urgent need for rapid and sensitive detection methods for vanillin.

Transcriptome analysis of planktonic cells in response to plasma medicine.

Cold plasma is frequently utilized for the purpose of eliminating microbial contaminants. Under optimal conditions, it can function as plasma medicine for treating various diseases, including infections caused by , an opportunistic pathogen that can overgrow in individuals with weakened immune system. To date, there has been less molecular study on cold plasma-treated .

Construction of a novel Eu-MOF material based on different detection mechanisms and its application in sensing pollutants aniline, F and Hg.

Aniline is an organic pollutant with carcinogenicity and teratogenicity, while F and Hg are toxic ions that are easily soluble in water. When they are released to the environment, they will pose a threat to human health. Designing a material that can simultaneously detect three types of pollutants is of great significance.

A novel noble-metal-free MoC-InS heterojunction photocatalyst with efficient charge separation for enhanced photocatalytic H evolution under visible light.

Currently, designing novel noble-metal-free photocatalysts with efficient carriers migration and catalytically active sites have been a researching hotspot in photocatalytic hydrogen evolution. In this paper, a novel noble-metal-free MoC-InS heterojunction was synthesized by a simple hydrothermal method. Morphology characterization revealed InS was attached to MoC.

Aqueous leaching of lithium from simulated pyrometallurgical slag by sodium sulfate roasting.

In the pyrometallurgical treatment for spent lithium-ion batteries (LIBs), lithium is generally present in slag with Al, Ca and Si and is hard to be further treated. In this study, lithium was recovered from a simulated pyrometallurgical slag (pyro-slag) sodium roasting and water leaching. The thermodynamic process for the reactions between slag and additives such as NaCl, NaNO and NaSO were simulated during roasting by the HSC software, where NaSO possessed stronger chemical reactivity.

A new fluorescent-colorimetric chemosensor based on a Schiff base for detecting Cr, Cu, Fe and Al ions.

A new Schiff base derivative fluorescence-colorimetric chemosensor 2-hydroxy-5-[(2-hydroxy-1-naphthyl)methylideneamino]benzoic acid (HL), has been designed and synthesized. HL displayed high selectivity and sensitivity for detecting Cr, Cu, Fe and Al ions in DMF/HO (v/v = 1/1) solution. When Cr, Cu or Fe ions were added, the solution of HL in DMF/HO exhibited different color changes.

The fluorescent property of 3-[(2-hydroxy-1-naphthyl) methylideneamino]benzoic acid and its application as fluorescent chemosensor for Hg and Al ions.

This manuscript studies the fluorescent property of 3-[(2-hydroxy-1-naphthyl)methylideneamino]benzoic acid (HL). Fluorescent spectra show that in different solvents, HL displays different fluorescent properties, which can be attributed to the interaction between the solvents and HL. Further study indicates that HL exhibits a highly selective and sensitive recognition for Hg ions in dimethylsulfoxide (DMSO), Al ions in methanol and N,N'-dimethylformamide/water (DMF/HO, 1/1, v/v).

3,3'-[Biphenyl-4,4'-diylbis(-oxy)]diphthalic acid.

In the title mol-ecule, C(28)H(18)O(10), the two central benzene rings form a dihedral angle of 31.0 (1)°. In the phthalic acid fragments, the carb-oxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.

[Preparation and catalytic activity of surface-modification CNTs/TiO2 composite photocatalysts].

A novel kind of carbon nanotubes/titanium dioxide (CNTs/TiO2) composite photocatalyst was prepared by a modified sol-gel method in which the nanoscaled TiO2 particles were uniformly deposited on the CNTs modified with poly(vinyl pyrrolidone) (PVP). The composites were characterized by a range of analytical techniques including high resolution transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results show the successful covering of the CNTs with PVP, forming core-shell structure.

[Mechanism study of fluoride adsorption by hydrous metal oxides].

Hydrous oxides of cerium, aluminum, nickel and copper were prepared by alkaline precipitation method. Langmuir adsorption isotherm was studied and specific surface area was measured by BET method through N2 adsorption-desorption process. IR characterization of hydrous metal oxides before and after fluoride adsorption was also studied.

[Removal of methyl orange from aqueous solution by magnetic carbon nanotubes].

Ferrocene was used as a catalyst, and xylene as carbon source. Chemical vapor deposition method was used to synthesize carbon nanotubes (CNTs). The CNTs were treated by oxidation method with concentrated nitric acid.

Study on solvent extraction of propionic acid from simulated discharged water in vitamin B12 production by anaerobic fermentation.

The potential of recovering propionic acid from discharged water in vitamin B(12) production by anaerobic fermentation was investigated in this paper. A primary amine, N(1923), was used as the extractant, kerosene as diluter and n-octanol as modifier. The influences of the content of N(1923) in the organic phase, the phase ratio and the pH of aqueous phase on the extraction yield of propionic acid were studied.
