Novel Electroless Plating of Ruthenium for Fabrication of Palladium-Ruthenium Composite Membrane on PSS Substrate and Its Characterization
This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولPreparation of Ruthenium(I1) and Ruthenium(II1) Myoglobin and the Reaction of Dioxygen, and Carbon Monoxide, with Ruthenium(I1) Myoglobin*
Ruthenium myoglobins have been prepared by the reconstitution of horse heart apomyoglobin with either ruthenium(I1) or ruthenium(II1) mesoporphyrin IX (MpIX) derivatives. The ruthenium(I1) and -(III) myoglobins (RuMb and RuMb+, respectively) contain one ruthenium porphyrin/heme binding site; the species are readily interconverted using dithionite for reduction and bromine for oxidation. RuMb bi...

متن کاملInteraction of Methanol with Ruthenium
The interaction of methanol with a clean <I 10) ruthenium surface has been studied using temperature programmed desorption methods. Methanol dissociates upon adsorption at 300 K and yields Ha(g) and chemisorbed CO as the domiwt products. Randomization of evolved hydrogen was shown to occur during methanol adsorption and also upon subsequent thermal desorption using isotopically labeled methanol...
