Enhancement of CO2 desorption using ultrasound and vacuum in water scrubbing biogas upgrading system
Fuqiang Jin,Haipeng Xu,Dongliang Hua,Lei Chen,Yan Li,Yuxiao Zhao,Bin Zuo 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.1
Ultrasound and vacuum were respectively employed to enhance CO2 desorption in a water scrubbing biogas upgrading system. Results showed that incomplete CO2 desorption could cause a high CO2 content in the water and seriously affect the purity of the product gas. Vacuum had a strong enhancement effect on CO2 desorption. When a vacuum of 0.04MPa was used to enhance CO2 desorption, the amount of the stripping air could be reduced to 1/16- th of that without enhancement, indicating that vacuum could greatly enhance CO2 desorption and significantly decrease the amount of the stripping air, which was expected to reduce a large amount of energy consumption. In contrast, the enhancement effect of ultrasound was not so obvious for CO2 desorption in the desorption column with air stripping, since the solution could be well desorbed by gas stripping, though ultrasound could strongly affect the static CO2 desorption.

Few-Layered MoS2 Nanostructures for Highly Efficient Visible Light Photocatalysis
Dan Li,Jianwei Li,Caiqin Han,Xinsheng Zhao,Haipeng Chu,Wenyan Lei,Xinjuan Liu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.10
Few-layered MoS2 nanostructures were successfully synthesized by a simple hydrothermal method without the addition of any catalysts or surfactants. Their morphology, structure and photocatalytic activity were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission electron microscopy, electrochemical impedance spectra and UV-Vis absorption spectroscopy, respectively. These results show that the MoS2 nanostructures synthesized at 180℃ exhibit an optimal visible light photocatalytic activity (99%) in the degradation of Rhodamine B owing to the relatively easier adsorption of pollutants, higher visible light absorption and lower electron–hole pair recombination.

Bradysia odoriphaga and B. difformis (Diptera: Sciaridae) are devastating pests of vegetables, ornamentals andedible mushrooms. In Chinese chive fields, the two Bradysia species occur with similar regularities: outbreaks inspring and autumn, and population decreases in summer. Temperature may be an important factor restrictingtheir population abundance in summer. Here, we performed a life-table study under constant high temperaturesand assessed the tolerance of two Bradysia species to heat shock. Life parameters of the Bradysia species indicatedslow developmental rates, and low survival rates and fecundity, when the temperature was higher than 30 °C. At34 °C, individuals were unable to reach the adult stages from eggs. Moreover, temperatures above 36 °C showedlethal effects, decreasing their survival rates. The median lethal time (LT50) values of 4th instar B. odoriphagaand B. difformis larvae were 46.82 and 32.97 h, respectively, while the values at 38 °C were 2.12 and 1.51 h,respectively. The 4th instar larvae and pupae possessed higher thermotolerance levels than adults and eggs,indicating sensitivities to heat stress. Moreover, B. odoriphaga was more thermotolerant than B. difformis. Thus,weak thermotolerance levels may restrict their occurrences during the period of summer heat, and the differencein thermotolerance levels between the two species may be related to their regional distributions.

Study on the Tensile and Shear Behaviors of Selective Laser Melting Manufactured Ti6Al4V
Hao Zhang,Tao Gao,Chang Xu,Lingyu Zhao,Haipeng Song,Ganyun Huang 대한금속·재료학회 2023 METALS AND MATERIALS International Vol.29 No.10
The deformation and failure of Ti6Al4V produced by Selective Laser Melting (SLM) under tensile and shear stress states have been experimentally investigated with different types of the samples. The digital image correlation (DIC) method was applied to observe the deformation, crack initiation and propagation behavior. The effects of building direction on the mechanical behavior were studied. The experimental results show that the yield strength and tensile strength of SLM manufactured Ti6Al4V along the build direction is slightly lower than the horizontal one, but the vertical samples have a higher ductility than horizontal samples. Fractographic analyses were conducted to investigate the damage mechanism and fracture mode of Ti6Al4V under different loading conditions. The defects and stress states have a significant influence on damage and failure behaviors of addictively manufactured Ti6Al4V alloy. The tensile stress tends to open up the defects in the vertically built specimen while the defects tend to be closed in the horizontally built specimen due to the building orientation. The nucleation, growth and coalescence of micro voids are the main damage mechanism of SLM fabricated Ti6Al4V alloy under tensile loading condition, and the void shearing mechanism dominates the failure of shear samples.

Polyethylene film mulching is commonly used in peanut (Arachis hypogaea L.) production, an important oil crop. Clear polyethylene film (CLEF) has previously been the only choice for all growing conditions. However, colored polyethylene film has been applied to the cultivation of crops in recent years, so testing the effects of colored film mulches on peanuts is necessary. In this study, we observed the effects of eight colored polyethylene films on devastating pest abundance, plant growth and yield, and soil conditions in peanut fields. The results showed that light-silver-gray film (LSGF), silver-black on both sides film (SGBF), and black film (BLAF) mulches were more effective in reducing the pest population (aphids, thrips, and mites) compared to plants mulched with other films. In addition, SGBF and LSGF mulching accelerated seeding emergence and benefited peanut growth, and the yield increased by about 20% compared to peanuts mulched with CLEF. The soil temperature and humidity under the LSGF and SGBF treatment were more suitable for peanut growth compared to the other film treatments. In conclusion, LSGF and SGBF mulches were appropriate choices for managing pests, maintaining optimum soil conditions, and increasing yield in peanut production.
