    Low Temperature H2 Production from Formic Acid Aqueous Solution Catalyzed on Metal Doped Mo2C

    Shuaishuai Zhu1, Zhigang Pan1,2, Yaqiu Tao1,2,*, Yue Chen1,2

    Journal of Renewable Materials, Vol.8, No.8, pp. 939-946, 2020, DOI:10.32604/jrm.2020.011197 - 10 July 2020

    Abstract Hydrogen is recognized as a promising energy scours in the close future. Online hydrogen preparation from formic acid under mild reaction conditions causes extensive interests. Mo2C and metal (Fe, Ni, Co, K) doped Mo2C on granular activated carbon (GAC) were prepared and used as heterogeneous catalysts for H2 generation from formic acid on a fixed bed reactor at 100–250°C. The formic acid conversions on doped Mo2C-Me/GAC are clearly improved, especially at lower reaction temperatures. Co doping presents outstanding effect on H2 selectivity and conversion rate compared to Ni and Fe. A 56.3% formic acid conversion was reached on More >

    Sub-Surface Drip Irrigation in Associated with H2O2 Improved the Productivity of Maize under Clay-Rich Soil of Adana, Turkey

    Alhan Sariyev1, Celaleddin Barutcular2,*, Mert Acar1, Akbar Hossain3, Ayman EL Sabagh2,4,5,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 519-528, 2020, DOI:10.32604/phyton.2020.09142 - 22 June 2020

    Abstract Maize being sub-tropical crop is sensitive to water deficit during the early growth stages; particularly clay-rich soil, due to the compaction of the soil. It is well-documented that potential sub-surface drip irrigation (SDI) (Full irrigation; SDIFull (100% field capacity (FC)), Deficit irrigation; SDIDeficit (70% FC)) improves water use efficiency, which leads to increased crop productivity; since it has a constraint that SDI excludes soil air around the root-zone during irrigation events, which alter the root function and crop performance. Additionally, in clayrich soils, the root system of plants generally suffers the limitation of oxygen, particularly… More >

    A Controlled Conditions of Dynamic Cold Storage Using Nano fluid as PCM

    Bin Liu1, Zhaodan Yang1, Yahui Wang1, Rachid Bennacer1,2

    FDMP-Fluid Dynamics & Materials Processing, Vol.13, No.1, pp. 37-47, 2017, DOI:10.3970/fdmp.2017.013.037

    Abstract The dynamic thermal history of storage product system is related to the insulation and also to the inertia. Use a new porous media doped with nanofluid PCM to improve the system efficiency. The analysis of the porous sponge thickness with 8 mm, 16 mm and 20 mm, the integrated nanofluids with 0.1%, 0.15% and 0.2%, the mass of the PCM and the initial temperature of the stored product with -1°C, 4°C, 12°C is achieved in order to underline the advantages of the new saturated porous media (sponges) with the phase change material (PCM) /Al2O3-H2O nanofluid.

    Impact of selenium fertilization on the activity of detoxifying enzymes of H2O2 in bean plants

    Hermosillo-Cereceres MA1, E Sánchez1, E Muñoz-Márquez1, A Guevara-Aguilar1, M García-Bañuelos1, D Ojeda-Barrios2

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 347-352, 2014, DOI:10.32604/phyton.2014.83.347

    Abstract Selenium (Se) is an essential element for many organisms, although in high concentrations it may become toxic, leading to the generation of reactive oxygen species (ROS). In this study, bean plants received different application rates of Se (0, 10, 20, 40, 80, and 160 µM) in the form of selenite and selenate to evaluate the activity of the detoxifying enzymes of H2O2. The results indicated that the activity of these enzymes in bean plants depended on the chemical form of Se: selenite at rates of 20 µM or greater diminished biomass and yield, increasing the activity More >

    Taguching the Atmospheric Plasma Spraying Process: Influence of Processing Factors on Droplet Impact Properties Obtained on Dense ZrO2 and H2Ar75% Plasma Gas

    Ridha Djebali1, Mohsen Toujani2, Bernard Pateyron3

    CMC-Computers, Materials & Continua, Vol.37, No.3, pp. 147-160, 2013, DOI:10.3970/cmc.2013.037.147

    Abstract In this paper a study of the atmospheric plasma spraying process was conducted. The Jets&Poudres code was used to solve the partial differential equations for the conservation of mass, momentum and energy involved in the problem together with the K-e turbulent model. The Taguchi technique was used to study the influence of processing factors on droplet impact properties obtained on dense zirconia (ZrO2) under H2Ar75% plasma gas that allow optimal functioning condition. The test of the operating parameters for the studied ranges showed that the "thermal power" factor plays a key role on the state of sprayed More >

    CMC-Computers, Materials & Continua, Vol.26, No.2, pp. 157-166, 2011, DOI:10.3970/cmc.2011.026.157

    Abstract The research on casing corrosion in sour environment by a synergism of sweet corrosion and H2S corrosion has become the basis of casing selection and casing string safety evaluation with more and more sour reservoirs containing high H2S concentration being developed. It is essential to scientifically utilize casing service ability and reasonably control production rate of gas well to achieve the effective and safe developing of gas resources during the safety period of casing service with a precise casing life prediction. Scanning electron microscopy and tensile testing were applied to investigate the corrosion of TP110TS tube More >

    Abstract Hydrogen technologies are currently one of the most actively researched topics. A lot of researches have tied to enhance their energy conversion efficiencies. In the present study, numerical analyses have been carried out focusing on hydrogen-storage carbon materials which are expected to realize high gravimetric and volumetric capacities. In particular, dissociative adsorption processes of H2 molecules above graphene surfaces have been investigated by ab initio molecular dynamics. The present results indicate that a steric graphene surface plays an important role in enhancing the charge transfer which induces dissociation of H2 and adsorption of H atoms on the More >
