Liu Haonan,Wu Han,Wang Ying,Wang Fan,Liu Xiaoli,Zhou Jianzhong 한국응용생명화학회 2021 Applied Biological Chemistry (Appl Biol Chem) Vol.64 No.6

A blueberry anthocyanin extract was obtained from Brightwell blueberry fruits cultivated in eastern China and the extraction and purification conditions were optimized. The components of the anthocyanin extract were identified using ultra-performance liquid chromatography-electrospray ionization interface-mass spectrometer. The antioxidant and antibacterial activities of the blueberry fruit supernatant (BFS), blueberry anthocyanin crude extract (BCE), and blueberry anthocyanin rich extract (BRE) were evaluated. The extraction yield was 1.79 ± 0.0014 mg/g under the following optimal conditions: 1:20 solid-to-liquid ratio (v/w), 24 h, 34 °C, and 90% ethanol containing 0.21% (v/v) hydrochloric acid. With regard to purification, anthocyanin purity increased 19.1-fold. Nine fractions were identified as the glycosides of delphinidin, cyanidin, petunidin, and malvidin. The biological activities of the blueberry anthocyanin extract were improved through extraction and purification. Compared with BFS and BCE, BRE had a higher DPPH radical scavenging activity ( EC50 = 0.51 mg/mL), ABTS antioxidant capacity ( EC50 = 0.32 mg/mL), and oxygen radical absorbance capacity (0.43 mmol Trolox/g). Furthermore, BRE (2 mg/mL) showed a maximum of 84.64 ± 0.35% reduction in the biofilm biomass of Listeria monocytogenes and the inhibition zone given by BRE against Escherichia coli was 16.04 ± 0.38 mm. BRE showed the highest antioxidant capacities and obvious antibacterial effects against foodrelated microorganisms than the other samples. Therefore, BRE can be used as a natural antioxidant and antibacterial agent and has potential health advantages and food industry applications.

Indicator of percolation transition in graphite oxide suspension containing cations

Liyan Liu,Jiale You,Haonan Zhu,Wei Tang 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.7

The percolation transition behavior occurs in the solid-liquid separation of graphite oxide (GO), whichchanges the system from suspension to colloid state and terminates the separation process. An indicator of percolationtransition is necessary to help control the status of GO suspension to finish the solid-liquid separation process. Theswell ratio, macroscopic appearance TEM, and rheological behavior of GO suspension were tested before and after thepercolation transition occurred in a specific interval of K+ concentration. Then, the physical properties of 1.00 g/L GOsuspension containing 0.40-0.80 g/L K+, including conductivity, thermal conductivity, viscosity, surface tension, andabsorbance were characterized. The values of these physical properties showed a sharp change in the specific interval ofK+ concentration. We calculated the first and second slope of two adjacent points of each physical property to obtain aproper percolation transition indicator. The conductivity with the second slope up to 500% was the most significantchange among these physical parameters, which can be used as an indicator of percolation transition in GO suspension. To verify the availability of the indicator, we explored the percolation transition behavior of Ca2+ and Al3+ in GOsuspension and K+ with different GO solid content, found that the conductivity is still the most significant percolationtransition indicator. The indicator obtained in this paper is reliable under varying content of GO and types of cations insuspension, which can be used to determine the percolation transition threshold during the solid-liquid separation ofGO suspension containing cations.

SUMMABILITY IN MUSIELAK-ORLICZ HARDY SPACES

Jun Liu,Haonan Xia Korean Mathematical Society 2023 대한수학회지 Vol.60 No.5

Let 𝜑 : ℝⁿ × [0, ∞) → [0, ∞) be a growth function and H^𝜑(ℝⁿ) the Musielak-Orlicz Hardy space defined via the non-tangential grand maximal function. A general summability method, the so-called 𝜃-summability is considered for multi-dimensional Fourier transforms in H^𝜑(ℝⁿ). Precisely, with some assumptions on 𝜃, the authors first prove that the maximal operator of the 𝜃-means is bounded from H^𝜑(ℝⁿ) to L^𝜑(ℝⁿ). As consequences, some norm and almost everywhere convergence results of the 𝜃-means, which generalizes the well-known Lebesgue's theorem, are then obtained. Finally, the corresponding conclusions of some specific summability methods, such as Bochner-Riesz, Weierstrass and Picard-Bessel summations, are also presented.

Effect of naphthalene quinoline and H2S on DBT hydrodesulfurization over unsupported NiMoW catalyst

Changlong Yin,Haonan Zhang,Tongtong Wu,Zhuyan Wu,Kunpeng Li,Yan Kong,Chengwu Dong,Chenguang Liu 한국화학공학회 2019 Korean Journal of Chemical Engineering Vol.36 No.12

Unsupported catalysts have attracted much attention for high activity in comparison with the traditional supported catalyst. Meanwhile, the clear structure of unsupported catalysts is helpful for the recognition of active phase for conducting the industry production. The NiMoW unsupported catalyst was prepared by hydrothermal synthesis and characterized by BET, XRD and HRTEM. The effects of naphthalene, quinoline and H2S on the hydrodesulfurization reactivity of dibenzothiophene (DBT) were investigated in both a batch autoclave and a continuous 10 ml fixed bed micro-reactor over NiMoW and supported catalyst for comparison. The results showed that the hydrogenation reaction and the hydrogenolysis reaction occurred on different active sites. For supported catalyst, the inhibition was relatively weaker, and the inhibition of the hydrodesulfurization pathway was much higher than the direct desulfurization pathway. Although unsupported catalyst was very sensitive to quinoline and H2S in this experiment, the HDS ratio on the unsupported catalyst was maintained at a high level above 99.7%, which is attributed to the very high active site density of unsupported catalysts.

Sedimentary characteristics and palaeoclimatic significance of glauberite in Paleocene lacustrine deposits of the Jiangling Depression, central China

The Paleocene sedimentary sequence in the Jiangling Depression was deposited in a salt lake environment. Based on detailed core observation of four drillholes in the Jiangling Depression, a study of sedimentary characteristics of glauberite in Paleocene lacustrine deposits was conducted through thin section petrography, X-ray diffraction, scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). This study has revealed five types of geological occurrences and six types of profile distribution features of glauberite. On the basis of petrological and mineralogical characteristics, we propose that the glauberite is mainly formed by crystallization from saturated sulfate solution and by ion exchange between sulfate solution and calcium-bearing pore solution. Glauberite mainly occurs in the late stage of Paleocene, when brine is relatively highly concentrated. Replacement of gypsum by glauberite is subordinate. The depositional model of glauberite is also discussed. The sulphur isotopic values δ34S) and the strontium ratios (87Sr/86Sr) of the sulphate suggest a non-marine brine supply. The profile distribution features of glauberite contribute to a better understanding of the past climate change. The glauberite in Late Paleocene is frequently interbedded with dolomite, anhydrite, halite or thenardite, suggesting fluctuation of lake water salinity and climate. Trace element compositions of the mudstones imply the reducing condition and fluctuating salinity. The Homogenization temperatures and hydrogen and oxygen isotopic values (δDSMOW and δ18OSMOW) in halite and thenardite inclusions further indicate that in Paleocene the temperature was relatively high and fluctuant. Moreover, the palaeoclimate was drier in the late stage of Late Paleocene, though the temperature was cooler/lower.
