Effect of immobilization on the activity of catalase carried by poly(HEMA-GMA) cryogels
(Elsevier B.V., 2019)
Hydrogen peroxide is converted by catalase to molecular oxygen and water to remove oxidative stress. In this study, catalase immobilization was performed using poly(2-hydroxyethyl methacrylate-glycidyl methacrylate) ...
Water-soluble polymeric particle embedded cryogels: Synthesis, characterisation and adsorption of haemoglobin
(Walter De Gruyter Gmbh, 2021)
Making cryogels, which are among today's accepted adsorbents, more functional with different methods, has been one of the subjects spent overtime. In this study, water-soluble poly(maleic anhydride-alt-acrylic acid) polymer ...
Zwitterionic amino acids as precursors for nonmetal cation pentaborate salts
(Wiley-V C H Verlag Gmbh, 2020)
Nonmetal cation (NMC) pentaborate structures were synthesized using the amino acid molecules as cations precursors. Chemical composition analysis, infrared spectroscopy, mass analysis, boron nuclear magnetic resonance, and ...
Novel coordination compounds of alkaline earth metals with coumarilic acid. Synthesis and characterization
(Elsevier B.V., 2021)
In this study, novel coordination compounds of coumarilic acid with 2A group alkaline earth metal cations [Mg2+ (1), Ca2+ (2), Sr2+ (3) and Ba2+(4)] were synthesized and structural characterized. The structural properties ...
Development of novel copper modified cryogels for biochemical isolation
(Springer, 2020)
Cu(II) anchored polymeric cryogels are synthesized for the isolation of B12. The poly(2-hydroxyethyl methacrylate) [poly(HEMA)] is used as solid support and N-methacryloyl-l-aspartic acid, is used as a ligand. Synthesis ...
A kind of energy storage technology: Metal organic frameworks
(2012)
Abstract- For last fifteen years energy has been transferred by using electricity. As an energy carrier electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. ...
Ca2+/Mg2+ co-substituted strontium nanohexaferrites: magnetic investigation and Mossbauer analysis
(Springer, 2019)
We report a comprehensive evaluation of the microstructures, magnetic, and hyperfine traits of Ca2+/Mg2+ co-substituted strontium nanohexaferrites (SHFs) of chemical compositions Sr1-2xCaxMgxFe12O19 (x <= 0.1). These SHFs ...
Impact of Eu3+ ion substitution on structural, magnetic and microwave traits of Ni-Cu-Zn spinel ferrites
(Elsevier Sci Ltd, 2020)
Partially europium (Eu) substituted Ni0.4Cu0.2Zn0.4EuxFe2-xO4(0.0 <= x <= 0.10) nanostructured spinel ferrites (NSFs) were produced by sol-gel auto-combustion strategy. The XRD analyses verified the existence of the ...
Impact of Gd substitution on the structure, hyperfine interactions, and magnetic properties of Sr hexaferrites
(Elsevier Sci Ltd, 2021)
Gd3+-substituted nano-sized Sr-hexaferrite, SrGd(x)Fe(12-x)O19 (0.00 <= x <= 0.05) NHFs (SrGd NHFs), were fabricated by a one-pot sol-gel combustion approach assisted by citric acid. The crystal structures, surface ...
Correlation between chemical composition, electrical, magnetic and microwave properties in Dy-substituted Ni-Cu-Zn ferrites
(Elsevier, 2021)
Dy3+ ion-substituted nanoferrites Ni0.4Cu0.2Zn0.4Fe2_ xDyxO4 (x <= 0.04) were produced via sol-gel method. Correlation between chemical composition, crystal structure, electrical, magnetic and microwave properties was ...
