Manganese Oxides with Different Morphologies In Situ Anchored onto TiCT Nanosheets: Highly Effective Decontamination toward Sulfur Mustard Simulants.

Manganese oxides with porous structure and abundant active sites show potential in degrading sulfur mustard (HD). However, there is an interface effect between the oily liquid HD and nano oxides, and the powder is prone to agglomeration, which leads to incomplete contact and limited degradation ability. Here, we demonstrate a simple hydrothermal method for preparing MnO/TiC composites to address this problem.

Catalytic activation of peracetic acid for pelargonic acid vanillylamide degradation by CoO nanoparticles in-situ anchored carbon-coated MXene nanosheets: Performance and mechanism insight.

Pelargonic acid vanillylamide (PAVA), a capsaicin-type dacryagogue agent utilized for counter-terrorism and riot control, possesses a low stimulus threshold. This characteristic can lead to environmental contamination following its application and may easily result in secondary stimulation to personnel. Cobalt-doped TiC-MXene nanosheets (CoO/TiC@C) were synthesized for the purpose of activating peracetic acid (PAA) and degrading PAVA.

EuRBG10 involved in indole alkaloids biosynthesis in Eucommia ulmoides induced by drought and salt stresses.

Alkaloids are natural products with many important medicinal activities. To explore the mechanism of abiotic stress promoting alkaloid biosynthesis in Eucommia ulmoides, transcriptomic analysis and metabonomic analysis were used, virus-induced gene silencing (VIGS) lines of target gene were constructed. The results showed that drought and salt stress caused wilting and blackening of leaves, decreased chlorophyll level, and significantly induced MDA and relative conductivity.

Degradation of malathion in the solution of acetyl peroxyborate activated by carbonate: Products, kinetics and mechanism.

The degradation process of malathion in the acetyl peroxyborate (APB) solution of different APB/malathion molar ratio and in the carbonate-activated APB (APB/CO) solution of different pH was studied by P NMR technology. In the APB solution, all malathion could be degraded in 47.5 min when the molar ratio of APB/malathion was 60.

Rapid activation of basic hydrogen peroxide by borate and efficient destruction of toxic industrial chemicals (TICs) and chemical warfare agents (CWAs).

The activation process of the B(OH)-activated HO solution and its performance toward toxic industrial chemicals (TICs) and chemical warfare agents (CWAs) were investigated to find an efficient way to destroy TICs and CWAs. B NMR analysis proved that B(OH) reacted rapidly with basic HO to produce peroxoborates ([B(OH)(OOH)]), and the proportional contents were closely related to the pH and temperature. O and ·O were generated, and their production increased exponentially with pH.

Bicarbonate-activated hydrogen peroxide and efficient decontamination of toxic sulfur mustard and nerve gas simulants.

C NMR spectra showed that peroxymonocarbonate (HCO) was generated in the NaHCO-activated HO solution and pH was a key factor in its production. A cycle for the bicarbonate anion was proposed as HCO→HCO → (CO)*→CO(aq)→HCO (HCO)→HCO (HCO) basing on the results of NMR, electron paramagnetic resonance, chemiluminescence analysis. In this cycle, (CO)* was the key intermediate and (CO)*→2CO+hv was the rate controlling step.

Association of rs4331426 and rs2057178 with Risk of Tuberculosis: Evidence from a Meta-Analysis.

Aims: A growing number of genome-wide association studies (GWAS) have revealed associations between single-nucleotide polymorphisms (SNPs) and susceptibility to tuberculosis (TB). However, the results of these studies have been inconclusive. This study evaluated whether the SNPs rs4331426 and rs2057178, identified by GWAS, are associated with TB susceptibility.

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.

Photocatalytic decomposition of acephate in irradiated TiO2 suspensions.

In the present study, the photocatalytic degradation of acephate (O,S-dimethyl acetyl phosphoramidothioate ((CH(3)O)(CH(3)S)P(O)NHCOCH(3))) in aqueous TiO2 suspensions is extensively investigated, pertaining to the concentration of photocatalyst and substrate on degradation rate of acephate. It is found that the acephate can be degradated and mineralized. The high-degradation rate is obtained with 4 g/L concentration of TiO2.
