Effect of Sintering Time on the Crystallisation, Morphology, Structure, Electric, Magnetic and Magnetocaloric Properties of La0.80Ag0.20MnO3
(SPRINGER, 2021)
The effects of sintering time -(t(S)) on the morphology, structure and magnetic properties of -La0.80Ag0.20MnO3 manganite perovskite investigated. The main purpose of the study was to explore the possibility of increasing ...
Synthesis and Characterization of Phenol/Urea/Formaldehyde and Clay Composites
(Polish Acad Sciences Inst Physics, 2014)
Recently, so-called "phenol-formaldehyde-urea resins", which are generally made only by mechanical blending of UF resin and alkaline type PF resins, have been used as adhesives for the manufacturing of wood products. Faster ...
Crystal structure of bis(isothiocyanato)[2,6-diacetylpyridine bis(4-hydroxybenzoylhydrazone)]Fe(III) Chloride bis(dimethylformamide) solvate
(Pleiades Publishing Inc, 2013)
The crystal structure of title compound (Fe[(C25H21N7O4S2)] center dot 4(C3NOH7), where C3NOH7 is dimethylformamide, DMF) was determined by the X-ray diffraction method. This compound crystallizes in the monoclinic C2/c ...
The aquaculture supply chain in the time of covid-19 pandemic: Vulnerability, resilience, solutions and priorities at the global scale
(Elsevier, 2022)
The COVID-19 global pandemic has had severe, unpredictable and synchronous impacts on all levels of perishable food supply chains (PFSC), across multiple sectors and spatial scales. Aquaculture plays a vital and rapidly ...
Organotin (IV) complexes derived from Schiff base 1,3-bis[(1E)-1-(2-hydroxyphenyl)ethylidene] thiourea: synthesis, spectral investigation and biological study to molecular docking
(Springer, 2021)
A novel Schiff base-derived organotin (IV) complexes have been synthesized by reacting 1, 3-bis [(1E)-1-(2-hydroxyphenyl)
ethylidene]thiourea (which in turn obtained by condensing thiourea with ortho-hydroxyacetophenone) ...
Determination of radioactivity levels in feldspathic dental ceramics
(Elsevier, 2021)
Activity concentrations of 42 different feldspathic dental ceramic powders were determined using a gamma spectrometer with an HPGe detector. The average 238U, 232Th and 226Ra activity concentrations of the specimens were ...
Optical refracting properties, birefringence and order parameter in mixtures of liquid crystals: Direct smectic A - Isotropic and reverse isotropic - Smectic A phase transitions
(Elsevier, 2022)
Due to the physical anisotropic and self-assembling nature, liquid crystalline materials holdvery important place in theoretical, experimental and applied physics. Besides, liquid crystals are important materials as working ...
A numerical method to solve fractional pantograph differential equations with residual error analysis
(SPRINGER HEIDELBERG, 2021)
In this study, we have introduced a fractional series solution method to solve fractional pantograph differential equations numerically. The method is constructed by collocation approach and Bernstein polynomials. Each ...
