Tuneable Giant Magnetocaloric Effect in (Mn,Fe)2(P,Si) Materials by Co-B and Ni-B Co-Doping
The influence of Co (Ni) and B co-doping on the structural, magnetic and magnetocaloric properties of (Mn,Fe) 2 (P,Si) compounds is investigated by X-ray diffraction (XRD), differential scanning calorimetry, magnetic and direct temperature change measurements. It is found that Co (Ni) and B co-doping is an effective approach to tune both the Curie temperature and the thermal hysteresis of (Mn,F...
متن کاملتهیه و شناسایی کاتالیزگرهای a/b/co-zy تهیه زئولیتy، نانوصفحه ای، تهیه زئولیت p
در بخش اول پروژه کاتالیزگرهای حذف کننده آلاینده nox سنتز و شناسایی شدند. زئولیتy با به سبب ویژگی های منحصر بفرد نظیر حفره سه بعدی با حجم بالا و خاصیت تبادل یونی بالا و نیز پایداری حرارتی به عنوان پایه کاتالیزگر انتخاب شد. برای سنتز کاتالیزگرها زئولیتy در محلول فلزات قلیایی و قلیایی خاکی و لانتانید مورد تبادل یونی قرار داده شد. تبادل یونی با فلزات واسطه باعث ایجاد کاتالیزگر های ناهمگن پرکاربرد د...
Is Each Boolean Algebra , B , h 2 ( B ) - Unsupported ?
If κ is an infinite cardinal, a complete Boolean algebra B is called κ-supported if and only if for each sequence 〈bβ : β < κ〉 of elements of B there holds V α<κ W β>α bβ = W A∈[κ]κ V β∈A bβ. We consider the problem of the existence of a non-atomic complete Boolean algebra B which is h2(B)-supported, where h2(B) is the minimal cardinal κ such that B is not (κ, 2)-distributive.
متن کاملCo-infection of influenza B and Streptococcus.
To the Editor—The recent report on ‘co-infection of influenza B and Streptococcus’ by Lam et al1 is very interesting. They reported “four cases infected with influenza B and streptococci that gave rise to severe pneumonia” and mentioned that “this is the second case report of severe invasive pneumococcal pneumonia secondary to influenza B infection.”1 Indeed, both influenza B and Streptococcus ...
متن کاملCatalytic oxidation of toluene over LaBO3 (B= Fe, Mn and Co) and LaCo0.7B′0.3O3 (B′= Fe and Mn) perovskite-type
In this paper, LaBO3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. Activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. LaCoO3 perovskite formulation showed the highest activity among LaBO3 (Fe, Mn and Co) perovskite catalysts. So, LaCoO3 perovskite based catalyst was s...
