Lipophilization of chitin as novel polymeric stabilizer for improved oil-in-water emulsions
(Springer, 2018)
To develop novel polymeric emulsifiers/stabilizers for improved functionalities, an array of chitin fatty acid esters (chitin octanoate, laurate, palmitate, and stearate) were synthesized using a trifluoroacetic anhydride ...
Effect of dc field on ac-loss peak in a commercial Bi:2223/Ag tape
(Edp Sciences S A, 2017)
Measurements of the ac susceptibility in a commercial Bi:2223/Ag tape for some different ac magnetic field amplitudes, H-ac, in the presence of bias magnetic field H-dc directed along H-ac are reported. It is found that ...
Magnetic Relaxation in a Y0.5Lu0.5Ba2Cu3Oy Superconductor at Various Magnetization Levels
(Springer, 2015)
The evolution of the rate of flux creep along the major hysteresis envelopes in a Y(0.5)Lu(0.5)Ba(2)Ca(3)Oy sample synthesized by a modified melt powder melt growth (MPMG) method at 25 K has been investigated. Magnetic ...
The Effect of Dy Doping on the Magnetic Behavior of YBCO Superconductors
(Springer, 2016)
The effect of dysprosium (Dy) doping on yttrium barium copper oxide (YBCO) prepared by conventional solid-state reaction method has been investigated by means of XRD, AC susceptibility, and DC magnetization measurements. ...
Improvement of Current Density of Different Atmosphere-Sintered Y358 Superconductors
(Springer, 2016)
Y3Ba5Cu8O18 (Y358) which is the last family member of YBCO superconducting material was produced by a solid-state reaction technique. During the production process, superconducting samples were sintered in different ...
Differential scanning calorimetry (DSC) and Ni+2 release analysis of NiTi-shape-memory dental alloys coated by micro-arc oxidation (MAO) method
(Springer Heidelberg, 2018)
This study aims to prevent the release of Ni+2 and increase the biocompatibility of NiTi-shape-memory dental alloys with the micro-arc oxidation (MAO) coating by preserving the shape-memory feature in the oral environment. ...
Chemical composition and bioactive properties of the essential oil of Rhinanthus angustifolius subsp grandiflorus
(Bulgarian Acad Science, 2017)
In this study, the chemical composition and antimicrobial activities of the essential oil of the Rhinanthus angustifolius subsp. grandiflorus plant were investigated. Essential oil was obtained from all parts of the plant ...
Automation in the Mining Industry: Review of Technology, Systems, Human Factors, and Political Risk
(Springer Heidelberg, 2019)
In the opinion of these authors, technology alone can never give an organization an edge over competitors or provide an industry step change. However, history has shown that technology applied with correct logistics and ...
