Abstract: nano-silicon (Si) and common Si on lead (Pb) toxicity, uptake, translocation, and accumulation in the riceThe results showed that Si application alleviated the toxic effects of Pb on rice growth.Pb concentrations in rice grains treated with common Si and nano-Si decreased by 21.3%–40.9% and 38.6%growth, preventing Pb transfer from rice roots to aboveground parts, and blocking Pb accumulation inrice grains, especially in high-Pb-accumulating rice cultivars and in heavily Pb-polluted soils.

PISKUNKOVA, I. B. PAVLOVA, L. L. ZAVALOVA, I. P. BASKOVA

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 203-209 doi: 10.1007/s11705-012-1277-2

Abstract: Antifungal activity of recombinant medicinal leech destabilase-lysozyme (rec.Dest-Lys) was investigated by using fungi: , and , including yeasts and . Its antibacterial activity was investigated on gram-negative bacteria . These activities were assessed by radial agar diffusion assay, and scanning and transmission electron microscopy. Therefore, destabilase-lysozyme not only is endo-isopeptidase and lysozyme, but also has antifungal and antibacterial activities. Muramidase activity of rec.Dest-Lys disappeared after heat-treating at 90°C for 50 min without the loss of its antimicrobial activity. Furthermore we showed for the first time that the heated-up derivative of rec.Dest-Lys exhibited more potent activities against the above enumerated fungi and gram-negative bacteria than original protein.

Dual enzyme activated fluorescein based fluorescent probe

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 117-121 doi: 10.1007/s11705-018-1785-9

Abstract: A simple dual analyte fluorescein-based probe ( ) was synthesised containing -glucosidase ( -glc) and hydrogen peroxide (H O ) trigger units. The presence of -glc, resulted in fragmentation of the parent molecule releasing glucose and the slightly fluorescent mono-boronate fluorescein ( ). Subsequently, in the presence of glucose oxidase (GOx), the released glucose was catalytically converted to D-glucono- -lactone, which produced H O as a by-product. The GOx-produced H O resulted in classic H O -mediated boronate oxidation and the release of the highly emissive fluorophore, fluorescein. This unique cascade reaction lead to an 80-fold increase in fluorescence intensity.

Utilisation of waste heat from exhaust gases of drying process

Arsenyeva,Lidija Čuček,Leonid L. Tovazhnyanskyy,Petro O. Kapustenko,Yana A.Kusakov,Oleksandr I. Matsegora

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 1,   Pages 131-138 doi: 10.1007/s11705-016-1560-8

Abstract: Nowadays a lot of low-grade heat is wasted from the industry through the off- and flue-gasses with different compositions. These gases provide the sensitive heat with utilisation potential and latent heat with the components for condensation. In this paper, process integration methodology has been applied to the partly condensed streams. A hot composite curve that represents the gas mixture cooling according to equation of state for real gases was drawn to account the gas-liquid equilibrium. According to the pinch analysis methodology, the pinch point was specified and optimal minimal temperature difference was determined. The location of the point where gas and liquid phases can be split for better recuperation of heat energy within heat exchangers is estimated using the developed methodology. The industrial case study of tobacco drying process off-gasses is analysed for heat recovery. The mathematical model was developed by using MathCad software to minimise the total annualised cost using compact plate heat exchangers for waste heat utilisation. The obtained payback period for the required investments is less than six months. The presented method was validated by comparison with industrial test data.

Multi-Pollutant Formation and Control in Pressurized Oxy-Combustion: SOx, NOx, Particulate Matter, and Mercury

Gaofeng Dai,Jiaye Zhang,Zia ur Rahman,Yufeng Zhang,Yili Zhang,Milan Vujanović,Hrvoje Mikulčić,NebojsaManić,Aneta Magdziarz,Houzhang Tan,Richard L.

Engineering doi: 10.1016/j.eng.2024.03.005

Abstract: Oxy-combustion is a promising carbon-capture technology, but atmospheric-pressure oxy-combustion has a relatively low net efficiency, limiting its application in power plants. In pressurized oxy-combustion (POC), the boiler, air separation unit, flue gas recirculation unit, and CO2 purification and compression unit are all operated at elevated pressure; this makes the process more efficient, with many advantages over atmospheric pressure, such as low NOx emissions, a smaller boiler size, and more. POC is also more promising for industrial application and has attracted widespread research interest in recent years. It can produce high-pressure CO2 with a purity of approximately 95%, which can be used directly for enhanced oil recovery or geo-sequestration. However, the pollutant emissions must meet the standards for carbon capture, storage, and utilization. Because of the high oxygen and moisture concentrations in POC, the formation of acids via the oxidation and solution of SOx and NOx can be increased, causing the corrosion of pipelines and equipment. Furthermore, particulate matter (PM) and mercury emissions can harm the environment and human health. The main distinction between pressurized and atmospheric-pressure oxy-combustion is the former’s elevated pressure; thus, the effect of this pressure on the pollutants emitted from POC—including SOx, NOx, PM, and mercury—must be understood, and effective control methodologies must be incorporated to control the formation of these pollutants. This paper reviews recent advances in research on SOx, NOx, PM, and mercury formation and control in POC systems that can aid in pollutant control in such systems.

Identification of pakchoi cultivars with low cadmium accumulation and soil factors that affect their cadmium uptake and translocation

Lin WANG,Yingming XU,Yuebing SUN,Xuefeng LIANG,Dasong LIN

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 6,   Pages 877-887 doi: 10.1007/s11783-014-0676-7

Abstract: The selection and use of low-Cd-accumulating cultivar (LCAC) has been proposed as one of the promising approaches in minimizing the entry of Cd in the human food chain. This study suggests a screening criterion of LCACs focusing on food safety. Pot culture and plot experiments were conducted to screen out LCACs from 35 pakchoi cultivars and to identify the crucial soil factors that affect Cd accumulation in LCACs. Results of the pot culture experiment showed that shoot Cd concentrations under the three Cd treatments significantly varied across cultivars. Two cultivars, Hualv 2 and Huajun 2, were identified as LCACs because their shoot Cd concentrations were lower than 0.2 mg·kg under low Cd treatment and high Cd exposure did not affect the biomass of their shoots. The plot experiment further confirmed the consistency and genotypic stability of the low-Cd-accumulating traits of the two LCACs under various soil conditions. Results also showed that soil phosphorus availability was the most important soil factor in the Cd accumulation of pakchoi, which related negatively not only to Cd uptake by root but also to Cd translocation from root to shoot. The total Cd accumulation and translocation rates were lower in the LCACs than in the high-Cd cultivar, suggesting that Cd accumulation in different cultivars is associated with the Cd uptake by root as well as translocation from root to shoot. This study proves the feasibility of the application of the LCAC strategy in pakchoi cultivation to cope with Cd contamination in agricultural soils.
