The author ABSTRACT A trial on dietary organic selenium (Se) supplementation with locally manufactured compound feed was conducted to evaluate sperm motility, sperm morphology, sperm concentration, sperm hole,fertility performance and testis weightof Japanese Quail. A total of 24 adult males and 60 breeder females were randomly and equally allocated to 25, 2.5, 0.25, and 0.0 ppm organic Se (Sel-Plex) supplemented diets having 3 replications in each. Results demonstrated that the semen quality was reduced (p<0.05) at 25 ppm Se supplemented groups without altering the feed intake, body weight and survivability of the bird. sperm motility, sperm morphology, sperm concentration, were found to be significantly higher (p<0.05) in the semen of 0.25 ppm organic Se supplemented birds. The sperm hole number were found to be markedly higher (p<0.05) at the 0.25 and 2.5 ppm organic Se supplementation. The fertility was also higher (p<0.05 ) in 0.25 ppm and 2.5 ppm Se supplemented eggs in comparison to that of control and 25 ppm Se supplementation. The weight of testis in the Se supplemented breeder quail did not differ significantly (p>0.05). The present study suggested that the compound breeder feed manufactured in Bangladesh is deficient of Se and its fortification with 0.25 ppm exogenous Sel-Plex is recommended for its use in breeder quail to ensure the optimum performance. However, an extensive trial on organic Se supplementation covering a range of poultry species and the available branded compound poultry feed is needed to generalize the present findings for the breeders of all poultry species.

Tunable layer dependent electrical and magnetic properties have been shown in these materials and the ability to grow in the hexagonal phase provides opportunities to grow isostructural stacked heterostructures. In this investigation, cobalt selenide (CoSe) and nickel selenide (NiSe) were grown in the hexagonal phase, which consist of central metal atoms that are natively ferromagnetic in bulk, hence providing the potential for interesting magnetic phases in thin film arrangements as well.

  • SEDERHOLMITE, WILKMANITE, KULLERUDITE, M..AKINENITE and TRUSTEDTITE, FIVE NEW NICKEL SELENIDE MINERALS 1)
    T 4 SEDERHOLMITE, WILKMANITE, KULLERUDITE, M..AKINENITE and TRUSTEDTITE, FIVE NEW NICKEL SELENIDE MINERALS 1) BY Y. VUORELAINEN, A. HUHMA AND A. H.A.KLI Outokumpu Co., Finland ABSTRACT Five new nickel selenide minerals from Kuusamo, NE-Finland are described. The minerals occur in veinlets in albitites associated with uranium mineralisation. Sederholmite, which is identical with the synthetic hexagonal fJ-NiSe phase, has a o = 3.62 - 3.65 A and eo = 5.29 - 5.34 A depending upon composition. Wilkmanite corresponds to the artificial monoclinic Ni3Se4 phase. Its a o = 6.22 A, b o = 3.63 A, CO = 10.52 A and fJ = 90.55°. Kullerudite NiSe 2 is an ortho-rhombic nickelian analogue of ferroselite with a o = 4.89 A, b o = 5.96 A and Co = 3.76 A. M:ikinenite, which is the same as the artificial y-NiSe phase, has a trigonal symmetry with a o = 10.01 A and Co = 3.28 A. Triistedtite is a cubic spinel type Ni3Se4 having a o = 9.94 A. It forms a solid solution series with polydymite. Members of this series with 40-70 mole per cent polydymite component have also been found.

    www.acsami.org Research Article Effect of Selenium Content on Nickel Sulfoselenide-Derived Nickel (Oxy)hydroxide Electrocatalysts for Water Oxidation Bryan R. Wygant, Anna H. Poterek, James N. Burrow, and C. Buddie Mullins* Cite This: ACS Appl. Mater. Interfaces 2020, 12, 20366−20375 Read Online ACCESS Metrics & More Article Recommendations *sı Supporting Information ABSTRACT: An efficient and inexpensive electrocatalyst for the oxygen evolution reaction (OER) must be found in order to improve the viability of hydrogen fuel production via water electrolysis. Recent work has indicated that nickel chalcogenide materials show promise as electrocatalysts for this reaction and that their performance can be further enhanced with the generation of ternary, bimetallic chalcogenides (i.e., Ni1−aMaX2); however, relatively few studies have investigated ternary chalcogenides created through the addition of a second chalcogen (i.e., NiX2−aYa). To address this, we fi studied a series of Se-modi ed Ni3S2 composites for use as OER electrocatalysts in alkaline solution. We found that the addition of Se results in the creation of Ni3S2/NiSe composites composed of cross-doped metal chalcogenides and show that the addition of 10% Se reduces the overpotential required to reach a current density of 10 mA/cm2 by 40 mV versus a pure nickel sulfide material. Chemical analysis of the composites’ surfaces shows a reduction in the amount of nickel oxide species with Se incorporation, which is supported by transmission electron microscopy; this reduction is correlated with a decrease in the OER overpotentials measured for these samples. Together, our results suggest that the incorporation of Se into Ni3S2 creates a more conductive material with a less-oxidized surface that is more electrocatalytically active and resistant to further oxidation.

What was once a united state of Bengal is now divided into two parts, the sovereign country of Bangladesh and the state of West Bengal in India. The predominant religion in Bangladesh is Islam and that of West Bengal is Hinduism. Throughout history, ideas and identifications of certain elements of culture as ‘tradition’ have played an important role in the construction of notions of identity in this region, where multiple cultures continue to meet.

Among different transition metals, nickel and copper are abundant electrocatalysts for energy-storage applications. Nickel–copper selenide (NiCuSe2) nanostructures were prepared on a stainless-steel mesh with a cost-effective, simple, and versatile electrodeposition method for supercapacitor applications. The change effect in the bath concentration of nickel and copper altered the structural and electrochemical properties of NiCuSe2 electrode. X-ray diffraction (XRD) patterns confirmed the pure phase of ternary NiCuSe2 thin films with a cubic crystal structure. The surface morphology of NiCuSe2 was tuned by nickel and copper from spherical porous nanoflowers, nanoplates, nanocubes, and nanosphere-like nanostructures deposited on the stainless-steel mesh.

State Street, Rolla, Missouri 65409, United States *S Supporting Information ABSTRACT: Developing low-cost electrocatalysts with high efficiency for water splitting is a critical task to make this technology viable for large-scale clean energy generation. Transition metal selenides, comprising earth abundant elements, such as Fe, Co and Cu, have gained attention as superior electrocatalysts for oxygen evolution reaction (OER) in the alkaline medium. In this article, we have systematically investigated the evolution of OER catalytic activity as a function of composition for a series of Fe−Co−Cu quaternary selenides by exploring a trigonal phase diagram. The OER activity was dependent on the quantity of Cu and Fe in the Fe-Cu-Co-Se quaternary selenide electrocatalysts, while surprisingly, Fe−Cu ternary selenides exhibit reduced OER activity in comparison to their pure parent compounds FeSe ffi and Cu3Se2. Quaternary selenides exhibited more e cient catalytic activity with increasing amount of Fe or Cu in the catalysts, fi and the quaternary mixed metal selenide thin lm of composition (Fe0.48Co0.38Cu0.14)Se showed the best catalytic performance −2 −1 with a small overpotential of 256 mV at 10 mA cm and a low Tafel slope of 40.8 mV dec in N2-saturated 1.0 M KOH solution.

  • Electrodeposited Transition Metal Oxide and Selenide Thin
    Electrodeposited Transition Metal Oxide and Selenide Thin Films for Supercapacitor Zhenjun Qi A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy School of Materials Science & Engineering Faculty of Science University of New South Wales September 2020 PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: QI First name: ZHENJUN Other name/s: Abbreviation for degree as given in the University calendar: Doctor of philosophy School: School of Materials Science and Engineering Faculty: Faculty of Science Title: Electrodeposited Transition Metal Oxide and Selenide Thin Films for Supercapacitor Abstract 350 words maximum: (PLEASE TYPE) As electrode materials of supercapacitors, transition metal oxide and selenide can exhibit superior specific capacitance and energy density, owing to their rich valence states for reversible faradaic reactions. In this dissertation, the simple and fast electrochemical deposition method has been implied to directly deposit transition metal oxide and selenide on suitable substrates to form thin films, which effectively avoids the use of polymer binders and conductive additives, thereby reducing the loss of electrode capacity. Moreover, the morphology, structure and composition of thin films can be controlled for better performance by simply adjusting the electrodeposition parameters, such as temperature, current, potential, and the composition of electrolyte. The main aspects of this research are as follows: (i) A temperature-controlled electrodeposition method was designed and utilized to Mn3O4 and Mn3O4/MnOOH nanocomposite thin films on FTO substrates. The performance of Mn3O4 based electrode was improved due to the optimized morphology and the synergistic effect between Mn3O4 and MnOOH. (ii) Mn3O4/MnOOH thin film with nanorods morphology was obtained by introducing Pt atoms during the electrodeposition and exhibited a superior electrochemical behaviour.
